Restful 调用返回错误请求。在 RestSharp 取得成功。使用 HttpClient/HttpWebRequest 失败

Question

好的！因此，我尝试向 Polycom 设备拨打这个 Restful 电话。

为了在这段代码中进行隔离，我使用了 RestSharp，它工作正常。还删除凭据对象或更改它会使其反击未经授权，因此我相信授权很好。我认为它的主体/参数不正确。

        //THIS SECTION WORKS 
        //RestRequest restRequest = new RestRequest();
        //restRequest.AddJsonBody(body);
        //RestClient restClient = new RestClient(targetUrl);
        //restClient.RemoteCertificateValidationCallback = (sPoint, cert, wRequest, certProb) => true;
        //restClient.Authenticator = new HttpBasicAuthenticator(username, deskPhone.MACPassword);
        //IRestResponse restsharpResponse = await restClient.ExecutePostAsync(restRequest).ConfigureAwait(false);
        //END SECTION 

我的问题是什么.. 我不知道为什么会收到错误 400 Bad Request。当我查看通话中的内容时，一切似乎都正确对齐。 Auth token 和 RestSharp 一样，body 是同一个对象。

我真的不知所措，不幸的是我不能使用restsharp，我需要使用Net Core中可用的东西。

我在代码中有几个不同的实现，如下所示。我尝试使用 HttpClient 并尝试使用 HttpWebRequest。

我的问题是......我有什么错误可能会阻止这是一个正确的请求。

此处的此链接指向 API 文档，我似乎也正确地对齐了该文档。 https://support.polycom.com/content/dam/polycom-support/products/voice/polycom-uc/other-documents/en/2018/ucsoftware-restapi.pdf

        HttpResponseMessage stuff = await httpClient.PostAsync(targetUrl, temp).ConfigureAwait(false);

        handler.Dispose();
        httpMessage.Dispose();

        httpClient.Dispose();
    }

所以下面是来自 fiddler 的两个比较。

问题孩子是这里的这一行。

request.ContentType = "application/json; charset=utf-8";

修复？？

request.ContentType = "application/json";

以下是导致发现的提琴手结果。
