I'm trying to create a Python script which can use the PATCH method to upload a file into MS's Common data service. I'm successfully making GET, POST, PATCH, and DELETE calls with simple data, but have so far been unable to configure it so that I can upload a file.
I've been using the Requests library for Python, with the requests.patch function in order to try updating the data. I'm attempting to upload a .csv file into the field, the file which i'm uploading has a filesize of 1kb.
If I upload the data directly into the common data service through the in-built data interface, my browser is able to correctly make a PATCH call. I've attempted to copy the call as closely as I can, but have had zero success.
File field in common data service
PATCH call in web browser
What is the correct way to make a PATCH request with a file to Microsoft's Common data service?
Made a mistake with the url in my request - I had missed out which field I was uploading data to
Incorrect URL:
https://90g9j3gf.crm4.dynamics.com/api/data/v9.0/test_entity(34cd854c-1175-4778-bf95-e1ce12dea3b0)
Corrected URL:
https://90g9j3gf.crm4.dynamics.com/api/data/v9.0/test_entity(34cd854c-1175-4778-bf95-e1ce12dea3b0)/test_field
The code I used to make the request:
Import requests
http_headers = {
'Authorization': 'Bearer ' + token['access_token'],
'Content-Type': 'application/octet-stream',
'x-ms-file-name': 'test.csv'
}
filedata = open("project-folder\\test.csv", "rb")
patch_req = requests.patch(
url, # My URL is defined elsewhere
headers=http_headers,
data=filedata
)
This now works correctly for me

We have many dozens of build pipelines and we want to pause and resume (re-enable) build pipelines from a simple webapp interface as we are making config changes frequently. Here is the MS doc explaining this API:
https://learn.microsoft.com/en-us/rest/api/azure/devops/build/builds/update%20build?view=azure-devops-rest-5.0#definitionqueuestatus
From this documentation, it appears I need to hit the REST API and change/toggle the DefinitionQueueStatus -- however, this documentation only shows a sample for a build specific operation, whereas I want to pause then re-enable the entire build pipeline. What is the proper way to make this call?
I'm using fetch - and I've tried many dozen formats in the call - the 'ourorg' and 'ourproject' are correct (we use this call structure for many other calls), but all fails for this call below. I grabbed the 'definitionID' from the URL I can visibly see when in the Azure devops portal on the specific build pipeline page, and I'm using it for the {buildID} as I don't know what else to put there. Any guidance to help here is appreciated - I don't need to use fetch btw - any working sample will help here:
fetch(https://dev.azure.com/our_org/our_projectname/_apis/build/builds/definitionId=1593?retry=true&api-version=5.0 {
method: 'PATCH ',
credentials: 'same-origin',
body: 'DefinitionQueueStatus: "Enabled"'
}).then(function(response) {
console.log(response);
})
It seems that the body is incorrect in your post. Here is sample about how to use POSTMAN to access Azure DevOps Services REST APIs.
Generate the PAT, and then record the token, it is important to use to authorization, please see this document.
Create a new request in POSTMAN, it is recommended to put the request in a collection for Azure DevOps Services REST API;
Select the authorization as Basic Auth, you can input the username as any value, and the password as the token which is generated in step1.
Basic Auth
Set the REST API which you want to use,and select the request method type(GET,POST,FETCH ....), here you use https://dev.azure.com/{organization}/{project}/_apis/build/builds/{buildId}?api-version=5.0.
In the Body tab, you can set the request body as raw in json format, and input the value as following:
{
"buildNumber":"#20190607.2",
"buildNumberRevision":1,
"definition":
{
"id":1,
"createdDate":null,
"queueStatus":"paused"
}
}
Everthing is ready now, you can send the request, if sccuess, you will get the response from the REST API.
In your post, the body content is incorrect, the Request Body should meet the format in the REST API document. The DefinitionQueueStatus is a type in definitions. In addition, if you send the request with parameter retry, you will get the message The request body must be empty when the retry parameter is specified..
Notice: This question is not about ANGULAR's HttpClient, but the document generated by a component's template.
I want to do an old trick for a simple, yet powerful MS EXCEL export: Generate an HTML document containing one single <table>, and serve it with "Content-Type: application/xls". The user's browser will forward the document to a locally installed MS EXCEL, which detects that this is not a "real" .xls, but HTML, and converts very nicely the HTML into a spreadsheet.
My approach to implement this is straigtforward: Add a route for path, say, "/export-xls", and a new component that gets the data and renders it in its template.
However I absolutely cannot find a way to set the "Content-Type" header in the response!? I envisage that in the "Routes" array I would set "contentType: 'application/xls'", but no way.
What is the easiest and best way to generate such a document from within ANGULAR?
You can solve your problem by doing following steps
create a file containing your table in your local file system and create a URL for that file using URL.createObjectURL method
send an http request to that file
intercept the request and add contentType: 'application/xls' to response headers
after receiving your file revoke the URL using URL.revokeObjectURL method and delete the file from your local file system
I am not sure if you can do this without the creation of physical file because you need an http request because of the response content type
I have created a lambda function using serverless. This function is fired via API Gateway on a GET request and should return a pdf file from a buffer. I'm using html-pdf to create the buffer and trying to return the pdf file with the following command
let response = {
statusCode: 200,
headers: {'Content-type' : 'application/pdf'},
body: buffer.toString('base64'),
isBase64Encoded : true,
};
return callback(null, response);
but the browser is just failing to load the pdf, so I don't know exactly how to return the pdf file directly to the browser. Could'nt find a solution for that.
well, I found the answer.
The settings in my response object are fine, I just had to manually change the settings in API Gateway for this to work in the browser. I have added "*/*" to binary media types under the binary settings in API Gateway console
API GATEWAY
just log into your console
choose your api
click on binary support in the dropdown
edit binary media type and add "*/*"
FRONTEND
opening the api url in new tab (target="_blank"). Probably the browser is handling the encoded base 64 response, In my case with chrome, the browser just opens the pdf in a new tab exactly like I want it to do.
After spending several hours on this I found out that if you set Content handling to Convert to binary (CONVERT_TO_BINARY) the entire response has to be base64, I would otherwise get an error: Unable to base64 decode the body.
Therefore my response now looks like:
callback(null, buffer.toString('base64'));
The Integration response:
The Method response:
And Binary Media Types:
If you have a gigantic PDF, then it will take a long time for Lambda to return it and in Lambda you are billed per 100ms.
I would save it to S3 first then let the Lambda return the S3 url to the client for downloading.
I was having a similar issue where pdf where downloaded as base64 and started happening when changed the serverles.yml file from:
binaryMediaTypes:
- '*/*'
to
binaryMediaTypes:
- 'application/pdf'
- '....other media types'
The issue is because the way AWS implemented this feature. From aws documentation here:
When a request contains multiple media types in its Accept header, API
Gateway honors only the first Accept media type. If you can't control
the order of the Accept media types and the media type of your binary
content isn't the first in the list, add the first Accept media type
in the binaryMediaTypes list of your API. API Gateway handles all
content types in this list as binary.
Basically if the first media type contained in the accept request header is not in your list in binaryMediaTypes then you will get base64 back.
I checked the request in the browser and the first media type in the accept header was text/html so I got it working after changing my settings to:
binaryMediaTypes:
- 'application/pdf'
- '....other media types'
- 'text/html'
Hope this helps anyone with the same issue.
Above solution is only for particular content-type. You can't more content type.
Follow only below two-step to resolve multiple content type issue.
Click on the checkbox of Use Lambda Proxy integration
API gateway --> API --> method --> integration request
Create your response as
let response = {
statusCode: 200,
headers: {
'Content-type': 'application/pdf',//you can change any content type
'content-disposition': 'attachment; filename=test.pdf' // key of success
},
body: buffer.toString('base64'),
isBase64Encoded: true
};
return response;
Note* - It is not secure
Instead of doing all this. It's better to use serverless-apigw-binary plugin in your serverless.yaml file.
Add
plugins:
- serverless-apigw-binary
custom:
apigwBinary:
types:
- "application/pdf"
Hope that will help someone.
I'm trying to display an Instagram feed on my website. I am not familiar with server side scripts. The explanations I have read go over my head.
I have managed to get an access key through Instagram but I don't know how to proceed.
I also tried the instructions from a video "How to implement an Instagram Feed in PHP without using the Instagram API"
For that, my php file works, displays the feed but I don't understand how to make it appear on my html page.
I'd be happy to make either method work.
In your HTML you should include a JavaScript 'script' element where you do something called an AJAX Request. The request will access the PHP file that produces the Instagram feed. ECHO the result from the PHP file and it will be returned into the DATA variable in the AJAX request. The request looks roughly like this:
$.ajax({
method: ‘POST or GET, most likely POST’,
url: ‘not always an actual url, this is the path to your PHP file’,
success: function(data) {
//php file returns into variable ‘data’
//display the feed within this function
}
});
The result from the PHP file should be echo’d back in JSON notation, if it isn’t, just add this to end of PHP the file:
$whatever = json_encode($your_result);
echo $whatever; //this is still the feed, just encoded in JSON
And if you need to decode it for some reason, just do
json_decode($variable_to_decode);
There are other parameters you can use in the AJAX request, like if for instance you need access to certain variables in your PHP file, that currently only exist in your HTML document.
this was solved by saving the html as php. i don't know why that is but it worked
I'm trying to upload a jpeg file for profile image using the Profiles REST API to IBM Connections_v5.0. I however get an error message "The type of the photo file you provided is not supported".
I'm however able to upload the same file directly using the Connections UI interface directly. I'm setting the MIME type correctly as "image/jpeg".
Also tried with GIF and PNG images but get the same error message.
Any pointers would be very helpful.
I'm just using FF restclient addon to fire a REST call. So basically doing a PUT on /profiles/photo.do?key=....
Content-Type is set as "image/jpeg" and the payload consists of the image data in binary (base 64) encoded.
The payload should just be the binary of the image, there is no need to Base64 encode it.
You should refer to Adding a Profile Photo
You need to use a Key (great stackoverflow post here)
If you know the key for a user's profile you can do the following:
key — This is generated by Connections itself during the population
process. It is used to define the users profile within the context of
Profiles and provides Connections with the ability to associate
content with a user when the users LDAP information has been altered.
It provides a separation of identity and helps facilitate user content
synchronization for Connections.
Once you have a key, you make the following request
URL: https://profiles.enterprise.example.com/profiles/photo.do?key=
b559403a-9r32-2c81-c99w-ppq8bb69442
METHOD: PUT
CONTENT-TYPE: image/png
input the binary content on the stream
you should be able to use "image/jpeg", "image/jpg", "image/png" or "image/gif"
If you have an error after the PUT method, you should add the SystemOut.log lines which are relevant.
