I am getting a 400 error (bad request) from this POST:
siteData.myPost = async function (url, data) {
let options = {
method: 'POST',
headers: {
'Content-Type': 'application/json;charset=utf-8'
},
body: JSON.stringify(data)
}
try {
const response = await fetch(quilkinUrlBase() + url,options);
return response.json();
}
catch (error) {
qPopup.Alert("Error with web request: " + error);
}
};
(the fetch address computes to "http://localhost:1337/UpdateSiteVisits").
This can't, of course, convert 'response' to json because the response is a DOC containing the 400 error message.
in server.js I have the following callback definition for the URL specified in the fetch:
app.post("/UpdateSiteVisits", sites.updateVisits);
in the debugger, the code never reaches updateVisits().
I have a very similar construct with a GET:
app.get("/GetSitesForType/:type", sites.findByType);
which works fine, so I assume the problem is with the 'options' object (which the GET doesn't use). In the POST case the data is just an integer ID, and if I change the data format to plain text (instead of json), the post works fine.
If leave the format as json, and send an object, rather than a simple integer, the post also works fine. So it looks like the system just doesn't like converting a single integer to json.
I needed to send the integer as json, so instead of using the method like this:
siteData.myPost("UpdateSiteVisits", siteID)
I needed to use
siteData.myPost("UpdateSiteVisits", { siteId: siteID })

Please ignore my question and answer, I was just getting mixed up with types. Such is the result from me converting from strongly-typed C# to untyped javascript!
I am trying to create a function which return the latest blocked domain from my pihole server.
I first created a JSON call, since the first call I needed was in JSON format, this is all working and I get the data needed.
However, the second function I need is to fetch plain text data and that one doesn't work, it simply returns an empty body [].
This is the function
socket.on("pihole_last", function() {
setInterval(function() {
let settings = {
method: "Get",
headers: {
"Accept": "text/html"
}
};
fetch('http://domain/admin/api.php?recentBlocked', settings)
.then(res => res.text())
.then((data) => {
console.log(data);
}).catch(error => {
return error;
});;
}, 1000)
});
The JSON function which works looks pretty much the same, the only real different is the header accept and the res.text() which should fetch the data in plain text?
The data returned from the URL is a plain text domain, no tags, no nothing.
According to this issue from the pi-hole GIT, you should provide some form of authentication. The question which you linked in your comment is 5 years old, at that time this was an unintended behaviour.
If I understand correctly the API description one way to authorize should be working with this url:
http://domain/admin/api.php?recentBlocked?auth=YOUR_TOKEN
The YOUR_TOKEN should be in:
Authorization & Token required (see WEBPASSWORD in /etc/pihole/setupVars.conf)
I am trying to write a NodeJS app that grabs a image from private URL using Axios and passes it to the Azure Face SDK (documentation) to detect faces in the image and get attributes of those faces - in this case, emotions and head pose.
I have gotten a modified version of the quickstart example code here working, which makes a call to the detectWithUrl() method. However, the image that I have in my code is a ArrayBuffer, so I thought I would try calling detectWithStream() instead. The documentation for this method says it needs to be passed something of type msRest.HttpRequestBody - I found some documentation for this type, which looks like it wants to be a Blob, string, ArrayBuffer, or ArrayBufferView. The problem is, I don't really understand what those are or how I might get from a arraybuffer image to an HttpRequestBody of that type. I have worked with HTTP requests before, but I don't quite understand why one is being passed to this method, or how to make it.
const rqs = {
responseType: 'arraybuffer',
url: `${fileUrl}`,
method: 'GET',
headers: {
'Content-Type': `image/jpeg`,
'Cache-Control': 'no-cache'
},
httpsAgent: agent
};
axios.request(rqs)
.then((ret) => {
// ret.data is a ArrayBuffer type;
let detected_faces = client.face.detectWithStream(ret.data, {
returnFaceAttributes: ["Accessories", "Age", "Blur", "Emotion", "Exposure", "FacialHair", "Glasses", "Hair", "HeadPose", "Makeup", "Noise", "Occlusion", "Smile", "QualityForRecognition"],
detectionModel: "detection_01",
recognitionModel: "recognition_03"
})
.then(ok => {
console.log(ok);
console.log("face(s) detected from image.");
console.log("Face attributes for face(s):");
})
.catch(err => {
console.error(err.message);
});
console.log('ok');
resolve(ret.data);
})
.catch((err) => {
console.error('nok');
console.error(err.message);
reject(false)
});
And I had receive a message error Only absolute URLs are supported
Only absolute URLs are supported -
a. it may be due to passing relative URL to Axios in line 3, try checking the fileUrl.
b. check the face SDK is provided with the proper endpoint
relative URL - "./a/b"
absolute URL - "https://www.x.com/a/b"
how I might get from an array buffer image?
Array buffer is not needed. Looking at face SDK code Ref (hope this is right sdk), we just need streams.
we can get this by changing the responseType value to stream
responseType: 'arraybuffer', // current
responseType: 'stream', // updated - we can update it in rqs and reponse will be stream and you can pass res.data to detectWithStream function
-------------------------------------Hope the code works----------------------------------------
Recommendation:
You are creating a callback hell by using nested .then chains what is call back hell.
Try using async/await syntax to achieve the same functionality in a simplified way - Ref.

I've been given the task to use the Azure Speech Recognition API on a Flutter application. The app is supposed to record the user's voice and send it to the Azure API. I've tried to use the only pub.dev plugin that I could find, but it did not work and the documentation does not have a Flutter example. Since the request returned 200 on Postman and I was able to make it work on a Javascript application, the problem must be my Flutter application, maybe something on the request, since it is returning code 400 (bad request), saying that the request contains invalid data.
The code below is my request to the API. The file which I'm using to get the bytes is a wav file containing the recorded voice
Could you help me? Thanks for the attention.
var bytes = file.readAsBytesSync();
var response = await Dio().post(
"https://brazilsouth.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=pt-BR",
data: bytes,
options: Options(
headers: {
"Ocp-Apim-Subscription-Key": "subscriptionKey",
"Content-Type": "audio/wav"
},
);
print(response.statusCode);
After trying to solve this problem for a couple of days, I finally got a successful response!
Future<dynamic> speechToText(File file) async {
final bytes = file.readAsBytesSync();
var headers = {
'Ocp-Apim-Subscription-Key': key,
'Content-Type': 'audio/wav'
};
var response;
Map<String, dynamic> responseBody;
var recognizedVoiceText;
try {
response = await http.post(
"https://brazilsouth.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=pt-BR",
body: bytes,
headers: headers,
);
// The response body is a string that needs to be decoded as a json in order to extract the text.
responseBody = jsonDecode(response.body);
recognizedVoiceText = responseBody["DisplayText"];
} catch (e) {
print('Error: ${e.toString()}');
recognizedVoiceText = "Something went wrong";
}
return recognizedVoiceText;
}
I know this question is not new but all the solution I get for this are in PHP or my issue is different from them.
I am using MWS feed API to submit flat file for Price and Quantity Updates and always get the following error:
the Content-MD5 HTTP header you passed for your feed did not match the
Content-MD5 we calculated for your feed
I would like to ask 3 questions here:-
ContentMD5Value parameter is optional as given in doc, but if i not passed that than it will say that you must enter ContentMD5Value.
As in doc the ContentFeed which we are given to Amazon. Amazon create contentMD5 for that file and then compares that contentMD5 value with the contentMD5 value we send to Amazon.
If both match then OK, otherwise it will throw an error. But if suppose I will not send the file then also the same errors come that MD5 does not match. How is that possible? Which file are they calculating the MD5 for? Because I haven't send the file in ContentFeed.
If I send the contentMD5 in a header as well as parameter and sending the ContentFeed in body, I still get the error.
Note:- I am sending the contentMD5 in a header as well as in a parameters in form using request module and also calculating the signature with that and then pass the contentFeed in body.
I am using JavaScript (Meteor), I calculate the md5 using the crpyto module.
First, I think that my md5 is wrong but then I tried with an online website that will give me the md5 for a file the md5.
for my file is:
MD5 value: d90e9cfde58aeba7ea7385b6d77a1f1e
Base64Encodevalue: ZDkwZTljZmRlNThhZWJhN2VhNzM4NWI2ZDc3YTFmMWU=
The flat file I downloaded from for Price and Quantity Updates:-
https://sellercentral.amazon.in/gp/help/13461?ie=UTF8&Version=1&entries=0&
I calculated the signature also by giving ContentMD5Value while calculating the signature.
FeedType:'_POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA_'
As, I read documentation for that I passed the MD5-header in headers and also send as parameter.
Amazon doc says:
Previously, Amazon MWS accepted the MD5 hash as a Content-MD5 header
instead of a parameter. Passing it as a parameter ensures that the MD5
value is part of the method signature, which prevents anyone on the
network from tampering with the feed content.
Amazon MWS will still accept a Content-MD5 header whether or not a
ContentMD5Value parameter is included. If both a header and parameter
are used, and they do not match, you will receive an
InvalidParameterValue error.
I am using the request module for http requests.
I am passing all the required keys, seller id, etc. in form of request module and passing the FeedContent in body.
I tried sending the file as follows:
Method for submitFeed is:-
submitFeed : function(){
console.log("submitFeedAPI running..");
app = mwsReport({auth: {sellerId:'A4TUFSCXD64V3', accessKeyId:'AKIAJBU3FTBCJUIZWF', secretKey:'Eug7ZbaLljtrnGKGFT/DTH23HJ' }, marketplace: 'IN'});
app.submitFeedsAPI({FeedType:'_POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA_'},Meteor.bindEnvironment(function(err,response){
if(err){
console.log("error in submit feed...")
console.log(err)
}
else{
console.log("suuccess submit feed....")
console.log(response);
}
}))
Method that call Amazon submitFeedAPI is:-
var submitFeedsAPI = function(options, callback){
console.log("submitFeedsAPI running...");
var fileReadStream = fs.createReadStream('/home/parveen/Downloads/test/testting.txt');
var contentMD5Value = crypto.createHash('md5').update(file).digest('base64');
var reqForm = {query: {"Action": "SubmitFeed", "MarketplaceId": mpList[mpCur].id, "FeedType":options.FeedType,"PurgeAndReplace":false,"ContentMD5Value":contentMD5Value}};
mwsReqProcessor(reqForm, 'submitFeedsAPI', "submitFeedsAPIResponse", "submitFeedsAPIResult", "mwsprod-0000",false,file, callback);
}
also try
var fileReadStream = fs.createReadStream('/home/parveen/Downloads/test/testting.txt');
var base64Contents = fileReadStream.toString('base64');
var contentMD5Value = crypto.createHash('md5').update(base64Contents).digest('base64');
mwsReqProcessor function is as below:-
mwsReqProcessor = function mwsReqProcessor(reqForm, name, responseKey, resultKey, errorCode,reportFlag,file, callback) {
reqOpt = {
url: mwsReqUrl,
method: 'POST',
timeout: 40000,
body:{FeedContent: fs.readFileSync('/home/parveen/feedContentFile/Flat.File.PriceInventory.in.txt')},
json:true,
form: null,
headers: {
// 'Transfer-Encoding': 'chunked',
//'Content-Type': 'text/xml',
// 'Content-MD5':'ZDkwZTljZmRlNThhZWJhN2VhNzM4NWI2ZDc3YTFmMWU=',
// 'Content-Type': 'text/xml; charset=iso-8859-1'
'Content-Type':'text/tab-separated-values;charset=UTF-8'
},
}
reqOpt.form = mwsReqQryGen(reqForm);
var r = request(reqOpt, function (err, res, body){
console.log(err)
console.log(res)
})
// var form = r.form();
//form.append('FeedContent',fs.createReadStream('/home/parveen/feedContent//File/Flat.File.PriceInventory.in.txt'))
}
Method for mwsReqQryGen generation:-
mwsReqQryGen = function mwsReqQryGen(options) {
var method = (options && options.method) ? ('' + options.method) : 'POST',
host = (options && options.host) ? ('' + options.host) : mwsReqHost,
path = (options && options.path) ? ('' + options.path) : mwsReqPath,
query = (options && options.query) ? options.query : null,
returnData = {
"AWSAccessKeyId": authInfo.accessKeyId,
"SellerId": authInfo.sellerId,
"SignatureMethod": "HmacSHA256",
"SignatureVersion": "2",
"Timestamp": new Date().toISOString(),
"Version":"2009-01-01",
},
key;
if(query && typeof query === "object")
for(key in query)
if(query.hasOwnProperty(key)) returnData[key] = ('' + query[key]);
if(authInfo.secretKey && method && host && path) {
// Sort query parameters
var keys = [],
qry = {};
for(key in returnData)
if(returnData.hasOwnProperty(key)) keys.push(key);
keys = keys.sort();
for(key in keys)
if(keys.hasOwnProperty(key)) qry[keys[key]] = returnData[keys[key]];
var sign = [method, host, path, qs.stringify(qry)].join("\n");
console.log("..................................................")
returnData.Signature = mwsReqSignGen(sign);
}
//console.log(returnData); // for debug
return returnData;
};
I also tried with following:-
reqOpt = {
url: mwsReqUrl,
method: 'POST',
timeout: 40000,
json:true,
form: null,
body: {FeedContent: fs.createReadStream('/home/parveen/feedContentFile/Flat.File.PriceInventory.in.txt')},
headers: {
// 'Transfer-Encoding': 'chunked',
//'Content-Type': 'text/xml',
// 'Content-MD5':'ZDkwZTljZmRlNThhZWJhN2VhNzM4NWI2ZDc3YTFmMWU=',
// 'Content-Type': 'text/xml; charset=iso-8859-1'
},
}
I also tried without JSON and directly send the file read stream in the
body, i.e:
reqOpt = {
url: mwsReqUrl,
method: 'POST',
timeout: 40000,
form: null,
body: fs.createReadStream('/home/parveen/feedContentFile/Flat.File.PriceInventory.in.txt'),
headers: {
// 'Transfer-Encoding': 'chunked',
//'Content-Type': 'text/xml',
// 'Content-MD5':'ZDkwZTljZmRlNThhZWJhN2VhNzM4NWI2ZDc3YTFmMWU=',
// 'Content-Type': 'text/xml; charset=iso-8859-1'
},
}
But same error comes every time:
the Content-MD5 HTTP header you passed for your feed did not match the
Content-MD5 we calculated for your feed
I want to know where I am doing wrong or what is the right way to submit feed API and sending the file using request module.
I also tried with the code given on MWS to generate the MD5 but same
error occurred each time.
My .txt file as follows:
sku price quantity
TP-T2-00-M 2
Any help is much appreciated
finally i got the solution as Ravi said above. Actually there are few points i want to clear here for you all who are facing the same issue:-
Amazon marketplace API doc is not giving proper information and example. Even i guess the documentation is not updated . As in doc they said that ContentMD5Value parameter value is optional on this page
You can check there they clearly mention that the field is not required but if you not pass than they gives the error that you must pass content MD5 value.
So that is wrong. ContentMD5 is required attribute.
They said in the same doc that you need to send file data weather its a xml or flat-file in the field key name i.e. FeedContent.
But that is also not needed you can send the file with any name no
need to give FeedContent key for the file you just need to send the
file in stream.
They will give the same error of contentMD5 not match weather you send file or not because if they not found file than the contentMD5 you send will not match to that. SO if you are getting the ContentMD5 not match error than check the following:-
Check that you are generating the right MD5 code for your file you can check whether you are generating the right code or not by there java code they given on doc . You can get that from this link
Don't trust on online websites for generating the MD5 hash and base64 encoding.
If your MD5 is matched with the MD5 generated from Java code they given than one thing is clear that your MD5 is right so no need to change on that.
Once your MD5 is correct and after that also if you get the same error that is:-
Amazon MWS SubmitFeed Content-MD5 HTTP header did not match the
Content-MD5 calculated by Amazon
ContentMD5 not matched .Than you need to check only and only you file uploading mechanism.
Because now the file you are sending to Amazon is not either correct or you are not sending it in the right way.
Check for file upload
For checking whether or not you are sending the right file you need to check with following:-
You need to send the required parameters like sellerId, marketplaceId, AWSAccessKey etc. as query params.
You need to send the file in the form-data as multipart , if you are using the request module of node.js than you can see the above code given by Ravi.
you need to set the header as only:-
'Content-Type': 'application/x-www-form-urlencoded'
No need to send the header as chunked or tab separated etc because i don't need them any more they are even confuse me because somewhere someone write use this header on other place someone write use this header.
So finally as i am abel to submit this API i didn't need any of the header rather than application/x-www-form-urlencoded.
Example:-
reqOpt = {
url: mwsReqUrl,
method: 'POST',
formData: {
my_file: fs.createReadStream('file.txt')
},
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
qs: { }// all the parameters that you are using while creating signature.
Code for creating the contentMD5 is:-
var fileData= fs.readFileSync('/home/parveen/Downloads/test/feed.txt','utf8');
var contentMD5Value = crypto.createHash('md5').update(fileData).digest('base64');
As i am facing the issue that is because i am using form and form-data simultaneously via request module so i convert my form data with qs(query string) and file in form-data as multipart.
So in this way you can successfully submit the API for submit feed.
Amazon requires the md5 hash of the file in base64 encoding.
Your code:
var fileReadStream = fs.createReadStream('/path/to/file.txt');
var file = fileReadStream.toString('base64'); //'[object Object]'
var contentMD5Value = crypto.createHash('md5').update(file).digest('base64');
wrongly assumes that a readStream's toString() will produce the file contents, when, in fact, this method is inherited from Object and produces the string '[object Object]'.
Base64-encoding that string always produces the 'FEGnkJwIfbvnzlmIG534uQ==' that you mentioned.
If you want to properly read and encode the hash, you can do the following:
var fileContents = fs.readFileSync('/path/to/file.txt'); // produces a byte Buffer
var contentMD5Value = crypto.createHash('md5').update(fileContents).digest('base64'); // properly encoded
which provides results equivalent to the following PHP snippet:
$contentMD5Value = base64_encode(md5_file('/path/to/file.txt', true));
Hey sorry for late reply but why don't you try to send the file in multipart in the form-data request and other queryStrings in 'qs' property of request module.
You can submit the request as follows:-
reqOpt = {
url: mwsReqUrl,
method: 'POST',
formData: {
my_file: fs.createReadStream('file.txt')
},
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
qs: {
AWSAccessKeyId: '<your AWSAccessKeyId>',
SellerId: '<your SellerId>',
SignatureMethod: '<your SignatureMethod>',
SignatureVersion: '<your SignatureVersion>',
Timestamp: '<your Timestamp>',
Version: '<your Version>',
Action: 'SubmitFeed',
MarketplaceId: '<your MarketplaceId>',
FeedType: '_POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA_',
PurgeAndReplace: 'false',
ContentMD5Value: '<your file.txt ContentMD5Value>',
Signature: '<your Signature>'
}
}
request(reqOpt, function(err, res){
})
Probably, I'm too late, but here are key points for C#:
1) Multipart form-data didn't work at all. Finished with the following (simplified):
HttpContent content = new StringContent(xmlStr, Encoding.UTF8, "application/xml");
HttpClient client = new HttpClient();
client.PostAsync(query, content)
2) About query:
UriBuilder builder = new UriBuilder("https://mws.amazonservices.com/");
NameValueCollection query = HttpUtility.ParseQueryString(builder.Query);
query["AwsAccessKeyId"] = your_key_str;
query["FeedType"] = "_POST_ORDER_FULFILLMENT_DATA_";
... other required params
query["ContentMD5Value"] = Md5Base64(xmlStr);
builder.Query = query.ToString();
query = builder.ToString();
3) About Md5base64
public static string Md5Base64(string xmlStr)
{
byte[] plainTextBytes = Encoding.UTF8.GetBytes(xmlStr);
MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider();
byte[] hash = provider.ComputeHash(plainTextBytes);
return Convert.ToBase64String(hash);
}
