如何使用承载令牌发布JSon

Question

我可以使用类似的代码和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：{Transfer-Encoding：chunked Connection：keep-alive Expect-CT：max-age = 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： __cfduid = dc0232e99fa0fefc0bd728258229dd5d51554273534; expires = Thu，02-Apr-20 06:38:54 GMT; path = /; domain = .paymentsapi.io; HttpOnly; Secure Server：cloudflare X-Powered-By：ASP.NET Content-Type： application / json; charset = utf-8}“

谁能看到我在做什么错？

提前致谢。

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();

PostAsJsonAsync将您的ByteArrayContent转换为json对象。 您可以使用醚PostAsJsonAsync直接与您的TestMaster像这样：

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();

或者你转换TestMaster以JSON和使用PostAsync用StringContent对象。 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();
