Forge Api修补程序请求返回415“不支持的媒体类型”

Question

我正在使用锻造API。我需要执行补丁请求。当我使用邮递员发送它时，一切都很好，但是当我使用HttpquiestMessage构建请求时，我会得到一个响应-"415不支持的媒体类型"。由API留档Content-Type I设置为"应用程序/vnd.apijson"。

邮递员的请求正文

请求对象结构

JObject jsonApi = new JObject();
            jsonApi.Add("version", "1.0");
            JObject attributes = new JObject();
            attributes.Add("displayName", file.FileName);
            JObject data = new JObject();
            data.Add("type", "items");
            data.Add("id", file.ExternalFileId);
            data.Add("attributes", attributes);

            JObject request = new JObject();
            request.Add("jsonapi", jsonApi);
            request.Add("data", data);

            using (var httpClient = new HttpClient())
            {
                HttpRequestMessage http = new HttpRequestMessage
                {
                    RequestUri = new Uri(url),
                    Method = new HttpMethod("PATCH"),
                    Headers =
                    {
                        { HttpRequestHeader.Authorization.ToString(), "Bearer " + userLastAccessToken },
                        { HttpRequestHeader.Accept.ToString(), "application/vnd.api+json" }
                    }
                };  
                http.Content = new StringContent(request.ToString(), Encoding.UTF8, "application/vnd.api+json");
                HttpResponseMessage responseMessage = await httpClient.SendAsync(http);
            }

Answer 1

好的，我通过这样设置ContentType解决了这个问题

http.Content = new StringContent(request.ToString(), Encoding.UTF8);
http.Content.Headers.ContentType = MediaTypeHeaderValue.Parse("application/vnd.api+json");

Answer 2

再次尝试使用"Application/json"或使用HttpHeaders。#################################################################################################################################

http.Content = new StringContent(request.ToString(), Encoding.UTF8, "application/json");

或：

http.Content = new StringContent(request.ToString(), Encoding.UTF8);
http.Headers.TryAddWithoutValidation("Content-Type", "application/vnd.api+json");
