http HeaderField request invalid

According to provided API, the request must include the following header:

x-http-request-info:{"clientRequestId":{"sessionId":"some_ID_number","requestId":"123456789"}}

If I use the webread, I can construct this as

requestId = struct('clientRequestId',struct('sessionId',sessionId,'requestId',requestId));
header = {'x-http-request-info'  jsonencode(requestId)};
options = weboptions('RequestMethod','GET','HeaderFields',header);
response = webread(url, options);

The problem with this approach is that webread does not return response-header, so I have to use the low level http commands.

However matlab.net.http.RequestMessage does not accept the above request header. I have tried to use matlab.net.http.HeaderField:

field1 = matlab.net.http.HeaderField('sessionId', sessionId);
field2 = matlab.net.http.HeaderField('requestId', requestId);
requestInfo = matlab.net.http.HeaderField('clientRequestId',[field1, field2]);
matlab.net.http.HeaderField('x-http-request-info', requestInfo);
method = matlab.net.http.RequestMethod.GET;
request = matlab.net.http.RequestMessage(method,header);
response = send(request,uri);

The response comes back with code 400 BadRequest

response = 

  ResponseMessage with properties:

    StatusLine: 'HTTP/1.1 400 '
    StatusCode: BadRequest
        Header: [1×8 matlab.net.http.HeaderField]
          Body: [1×1 matlab.net.http.MessageBody]
     Completed: 0
     
response.Body.Data.messages

ans = 

  struct with fields:

         key: 'request.header.invalid.x-http-request-info'
    severity: 'ERROR'
     message: 'Der Header 'x-http-request-info' ist fehlerhaft.'

What is the correct way to specify this particular header?

Many thanks in advance!

Hi Victor,

I see that you want to set a custom header for your GET request. “webread” method lets you do this however you mentioned that you want to use a lower-level HTTP method for the same.

I suggest that you checkout “urlread2” from the File Exchange: https://www.mathworks.com/matlabcentral/fileexchange/35693-urlread2

Thanks & regards,
