如何使用承载令牌发布JSon

Question

我可以使用类似的代码和承载令牌进行GET，但似乎无法完成POST。

当我将Json、URL和承载令牌复制/粘贴到Postman中时，效果非常好。但从C#执行此操作时，会出现以下错误：

“状态代码：400，原因短语：'错误请求'，版本：1.1，内容：System.Net.Http.StreamContent，标题：{传输编码：分块连接：保持活动预期CT：最大年龄=604800，报告uri=”https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct“CF-RAY:4c190ad8ad786539 SYD日期：2019年4月3日星期三06:38:54 GMT Set Cookie：\u cfduid=dc0232e99fa0fefc0bd728258229dd5d51554273534；expires=周四，20年4月2日06:38:54 GMT；path=/；domain=.paymentsapi.io；HttpOnly；安全服务器：cloudflare X-Powered-By:ASP.NET内容类型：应用程序/json；charset=utf-8}”

有人能看出我做错了什么吗？

提前谢谢。

JsonSerializerSettings jss = new JsonSerializerSettings();
string strValue = JsonConvert.SerializeObject(TestMaster, jss);
lblJSon.Text = strValue;        // This Json is valid
ByteArrayContent bytecontent = new ByteArrayContent(System.Text.Encoding.UTF8.GetBytes(strValue));
bytecontent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

string AccessToken = lblToken.Text;

HttpClient tRequest = new HttpClient();
tRequest.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", AccessToken);

Task<HttpResponseMessage> getTask = tRequest.PostAsJsonAsync(new Uri(strURL).ToString(), bytecontent);

HttpResponseMessage urlContents = await getTask;

Console.WriteLine("urlContents.ToString");
lblEDDR.Text = urlContents.ToString();

将您的ByteArrayContent转换为json对象。您可以将ether直接与TestMaster一起使用，如下所示：

string AccessToken = lblToken.Text;

HttpClient tRequest = new HttpClient();
tRequest.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", AccessToken);

Task<HttpResponseMessage> getTask = tRequest.PostAsJsonAsync(new Uri(strURL).ToString(), TestMaster);

HttpResponseMessage urlContents = await getTask;

Console.WriteLine("urlContents.ToString");
lblEDDR.Text = urlContents.ToString();

或者将TestMaster转换为Json，并将PostAsync与StringContent对象一起使用。像这样：

JsonSerializerSettings jss = new JsonSerializerSettings();
string strValue = JsonConvert.SerializeObject(TestMaster, jss);
lblJSon.Text = strValue;        // This Json is valid
StringContent strcontent = new StringContent (strValue);
bytecontent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

string AccessToken = lblToken.Text;

HttpClient tRequest = new HttpClient();
tRequest.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", AccessToken);

Task<HttpResponseMessage> getTask = tRequest.PostAsync(new Uri(strURL).ToString(), bytecontent);

HttpResponseMessage urlContents = await getTask;

Console.WriteLine("urlContents.ToString");
lblEDDR.Text = urlContents.ToString();
