Got message 'HTTP/1.1 401 Unauthorized' when tried to access user profile (https://graph.microsoft.com/v1.0/me)

so you do get a response now, try now without the Async, i think problem might be in the Async method now.  (not in the method, but how you handle it).

I never used that method, i believe you have to have an event catching the response or something like that ?

(can check that tomorrow, i now go to bed : )

I tried Execute instead of ExecuteAsync, Response.JSONValue is still null.

Very strange, if you get a response code of 200 and you see the body in the proxy it should have a value, can you see if request.Response.Content contains any text?

(debug it right after request.execute in your code)

Here are the values I got during debug:

 

RESTProfileResponse.Content : ''
RESTProfileResponse.ContentLength : 348
RESTProfileResponse.ContentType : 'application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false'
RESTProfileResponse.ContentEncoding : ''
RESTProfileResponse.FullRequestURI : 'https://graph.microsoft.com/v1.0/me'
RESTProfileResponse.Headers : (nil, $5A528A0, #$D#$A, nil, 0, ',', '"', '=', [soWriteBOM,soTrailingLineBreak,soUseLocale])
RESTProfileResponse.JSONText : ''
RESTProfileResponse.JSONValue : nil
RESTProfileResponse.Observers : ($120E3090, TComponent.GetObservers$ActRec($120FFAB4) as TObservers.TCanObserveEvent, TComponent.GetObservers$ActRec($120FFAB0) as TObservers.TObserverAddedEvent)
RESTProfileResponse.RootElement : ''
RESTProfileResponse.StatusCode : 200

ah ok.

You can see that there is content (348 bytes)
 

but i think i know the problem, probably your accept header is not ok.

more will follow in a minute, i check something.....

 

you have this RESTProfileRequest.Params.AddItem('Accept', '*/*', TRESTRequestParameterKind.pkHTTPHEADER); somewhere? 

 

change the '*/* in 'application/json'

or better just use the constant: CONTENTTYPE_APPLICATION_JSON

(is declared in the Rest.Types unit)

 

i use:

req.AddParameter('Accept', ctAPPLICATION_JSON, pkHTTPHEADER, [TRESTRequestParameterOption.poDoNotEncode]);

I don't have setting 'Accept'.

After I added req.AddParameter('Accept', ctAPPLICATION_JSON, pkHTTPHEADER, [TRESTRequestParameterOption.poDoNotEncode]);

the JSONValue is still null.

 

Just check the component, there is setting for Accept: 'application/json, text/plain; q=0.9, text/html;q=0.8,'

very strange. and in the proxy you still  get json text in the response?

Here are what I got from Charles Proxy. Is the header with size 0 normal?

 

[mvanrijnen 121]

but there is clearly JSON data in the response, i really would not know where your response content is empty

The Content-Type header value looks suspicious:

 

application%2Fjson

 

 

RESTListResGroupResponse.JSONValue maybe is empty because the content type is not the expected one, application/json

 

As can be seen in the screen shot, all other slashes are not encoded as #2F.

 

If the request header Content-Type is not required, just remove it from the request setup and try if this helps.

I created TRESTClient/Request in the code, and used seperate Clients. Still got JSONValue null. Is it possible that TRESTClient doesn't work in some situation?

i'm out of idea, very strange that you get a statuscode 200, visible content in the proxy but not content in the delphi object.

It turns out that TRESTResponse may have some bug. Remember the 'ContentLength' is 348, and 'Content' is empty? After encode the 'RawBytes' of the response, I can see the profile content. For some unknown reason, TRESTResponse ignores the content.

Thanks for all the replies.

Could you attach/upload the last version of your code? This would make it easier to reproduce the issue and to create a bug report for it.
