Question

我能够使用类似的代码和Bearer令牌进行GET，但似乎无法执行POST。

当我将Json，URL和Bearer Token复制/粘贴到Postman时，它可以正常工作。但是从C＃执行此操作时，出现此错误：

“ StatusCode：400，ReasonPhrase：“错误请求”，版本：1.1，内容： System.Net.Http.StreamContent，标头：{传输编码：分块连接：keep-alive Expect-CT：最大年龄= 604800， report-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：__cfduid = dc0232e99fa0fefc0bd728258229dd5d51554273534; expires =星期四，格林尼治标准时间20年4月2日06:38:54；路径= /; domain = .paymentsapi.io; HttpOnly;安全服务器：cloudflare X-Powered-通过：ASP.NET 内容类型：application / json; charset = utf-8}“

有人可以看到我在做什么吗？

先谢谢了。

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();

PostAsJsonAsync将您的ByteArrayContent转换为json对象。您可以像这样直接将PostAsJsonAsync和以太TestMaster一起使用：

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();

或者您将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();

如何使用承载令牌发布JSon
