I have an API end-point which takes a query string as url-encoded form data and returns a json.
I have used "Content-Type":"application/x-www-form-urlencoded" as headers.
When I try sending "query=xxx" as body of http post call using composer I get an error in emulator saying "The parent is missing.".
When I try sending {"query":"xxx"} as body, I get an error in emulator saying :
Misused header name. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects.
In which format should I send the data?
You should send it like this:
URL:http://localhost:7071/api/GetStudentGrade
Body(string):studentID=${user.studentID}&coursecode=${user.coursecode}
Content type:application/x-www-form-urlencoded

I think you have to change the body to an object, Also content type to application/json. Let me know if this resolves your issue.

My pdf file is being sent to my server as binary data with Postman as seen in the picture attached.
The content of the file is being parsed on my ExpressJS server with req.on((chunk) => ...) etc.
Everything is fine, except the fact that I try to obtain the original filename(highlighted in red - valid-compressed-compressed.pdf) on the server, but I can't find the value anywhere in the request object.
Any suggestions, please?
Short answer: you cant.
If you look closely at the headers being sent with the request, there are no headers containing the filename. Therefore there are no headers you can access in express to retrieve that information. The only headers you send are Content-Type and Content-Length that gives some information about what you're sending. Other than that there's just the binary request body.
If you want to post a file and the filename you need to look into multipart/form-data (Multer).
I'm trying to log in into a site which requires grcp content-type using requests. I alrady have a HTTP 2 client, but I don't know how body of my post request should look like.
When I'm trying to simply copy request as a curl from chrome network tab, request body looks like this:
%äEMAIL"PASSWORD(0
When I'm trying to request site with same body as I copied from chrome tab, I'mm getting response with this headers:
Grpc-Message: grpc: received message larger than max (218767392 vs. 4194304)
Grpc-Status: 8
I'm sure It's becouse wrong payload format
If anybody knows how can I pass data in request plase help.
If you're trying to send a one-off gRPC request, https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md would be helpful to know as to how to construct a message. Otherwise, using gRPC clients (https://github.com/grpc/grpc) would make more sense.
In my integration tests, ContentType is null when I make Get requests using ServiceStack's JsonServiceClient. However all the Post requests have a ContentType. Is it excluded on purpose? ie. Do I need a content type for http get requests?
Is there a way I can set the ContentType using this client?
There is no Content-Type for GET Requests since it doesn't have a Request body.
The Content-Type on the Request Header specifies what format the Request Body is in, likewise when on the Response Body specifies what format the Response Body is in.
You may instead be after the Accept HTTP Request Header which tells the server the preferred Content Types it would like the Response in.
i' m a bit new to Node, so question may be stupid...
I am sending a POST request to a website (through http.request) and I want to be able to use the invisible POST data I get along the response.
I hope this is achievable, and I think so since I am able to preview those data in Chrome debugger.
PS : I understand that we can use BodyParser to parse and get those while listening for a POST call server side, but I have found no example of how to use it coupled with an http.request.
Thanks !
If the body of the HTTP response contains JSON, then you need to parse it first in order to turn it from a string into a JavaScript object, like this:
var obj = JSON.parse(body);
console.log(obj.response.auth_token);
More info on various ways of sending a POST request to a server can be found here: How to make an HTTP POST request in node.js?
Edit : So we figured it out in the comments. The value I needed was in the form to begin with, as a hidden field. My error was to think it was generated afterward. So I'll just grab it first then login, so I can use it again for future POST requests on the website.
I am sending a JSON object from web client, which looks like this:
{"AudioEncoder":{"Settings":{"1":{"audio_bitrate":"16000"}}}}
And in the request I get from req.body.myvalue:
{"AudioEncoder":{"Settings":[null,{"audio_bitrate":"16000"}]}}
In the Network panel of my browser I see correct value though:
myvalue[AudioEncoder][Settings][1][audio_bitrate]:16000
Error is where I am expecting object with key {1:... but get [null:....
Any ideas why would this happen?
I suspect your browser isn't actually sending JSON, it's sending application/x-www-form-urlencoded. This is not the correct value if you are trying to have the browser send JSON: myvalue[AudioEncoder][Settings][1][audio_bitrate]:16000. That's not JSON. Check the request headers for Content-Type and look at the raw body of the request to verify this. If you post your browser JS that's sending the AJAX, we can help you fix that. jQuery makes it a little tricky to specify the options correctly to get it to really send JSON.
