Answer 2

using RestSharp;

ServicePointManager.SecurityProtocol = (SecurityProtocolType)48
| (SecurityProtocolType)192 | (SecurityProtocolType)768 | (SecurityProtocolType)3072;
var client = new RestClient("https://localhost:4009/connect/token");
var request = new RestRequest(Method.POST);
request.AddHeader("content-type", "application/x-www-form-urlencoded");
request.AddParameter("application/x-www-form-urlencoded"
, "grant_type=client_credentials&client_id="m2m2"&client_secret="uykykjh"&audience=Api&scope=Api", ParameterType.RequestBody);
IRestResponse response =await client.ExecuteAsync(request);
var result = JsonConvert.DeserializeObject<ResponseMessage>(response.Content);
//api call
//the same code with microsoft httpclient api works here
HttpClient apiclient2 = new HttpClient();
apiclient2.DefaultRequestHeaders.Authorization
= new AuthenticationHeaderValue("Bearer", result.access_token);
var result2= await apiclient2.GetAsync("https://localhost:44347/weatherforecast/notedited/1");
var content = await result2.Content.ReadAsStringAsync();

        /*************this code is not working*****************************/
      //  api call
        var apiclient = new RestClient("https://localhost:44347/weatherforecast/notedited/1");
        var apirequest = new RestRequest(Method.GET);

        apirequest.AddHeader("content-type", "application/json");
        apirequest.AddHeader("authorization", string.Format( "Bearer {0}" , result.access_token));
       // IRestResponse apiresponse =  apiclient.Execute(request);
        //the error appears here "Method not allowed"******************/
        IRestResponse apiresponse = await apiclient.ExecuteAsync(request);
        /*************this code is not working ends*****************************/

Answer 3

I don’t use restsharp, but why are you setting the content type on a get?

Answer 4

Hi @Erum Mirza ,

...  
var request = new RestRequest(Method.POST);  
...  
//api call  
//the same code with microsoft httpclient api works here  
HttpClient apiclient2 = new HttpClient();  
apiclient2.DefaultRequestHeaders.Authorization  
= new AuthenticationHeaderValue("Bearer", result.access_token);  
var result2= await apiclient2.GetAsync("https://localhost:44347/weatherforecast/notedited/1");  
var content = await result2.Content.ReadAsStringAsync();  

     /*************this code is not working*****************************/  
   //  api call  
     var apiclient = new RestClient("https://localhost:44347/weatherforecast/notedited/1");  
     var apirequest = new RestRequest(Method.GET);  
          
     apirequest.AddHeader("content-type", "application/json");  
     apirequest.AddHeader("authorization", string.Format( "Bearer {0}" , result.access_token));  
    // IRestResponse apiresponse =  apiclient.Execute(request);  
     //the error appears here "Method not allowed"******************/  
     IRestResponse apiresponse = await apiclient.ExecuteAsync(request);  
     /*************this code is not working ends*****************************/  

The cause of the problem is that you used the wrong RestRequest, which using different request method. Please check the code above: at lines 2, 15 and 21.

From the HttpClient request, we can know that the weatherforecast/notedited/1 end point should be accessed via the Get method.

IRestResponse apiresponse = await apiclient.ExecuteAsync(request);  

But from the above code, when using the RestClient, you are using the request (which is the Post method), you should change it to apirequest (this is the Get method). Change the code as below:

IRestResponse apiresponse = await apiclient.ExecuteAsync(apirequest);  

Besides, the above change still not working, try to remove the follow code:

     apirequest.AddHeader("content-type", "application/json");
