我试图将一个json字符串发布到Web API时,出现了以下错误信息(这是包含System.IO.File.WriteAllText的行写入文件的内容):
Response: StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Pragma: no-cache
Cache-Control: no-cache
Date: Thu, 13 Aug 2015 21:26:12 GMT
Server: Microsoft-IIS/8.5
X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET
Content-Length: 36
Content-Type: application/json; charset=utf-8

}
我的异步发布方法中的代码如下:
Uri theUri = new Uri("http://www.website.com/WebsiteAPI/PostDetails");
HttpClient aClient = new HttpClient();
aClient.BaseAddress = theUri;
aClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
aClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", "USERNAME", "PASSWORD"))));
aClient.DefaultRequestHeaders.Host = theUri.Host;
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, theUri);
request.Content = new StringContent(resource, Encoding.UTF8, "application/json");
// Post the data
aClient.SendAsync(request).ContinueWith(responseTask =>
{
System.IO.File.WriteAllText(PROFILE_JSON_PATH, "Response: " + responseTask.Result);
});
我尝试了许多不同的在线解决方案,但似乎都无法正常工作。有任何想法为什么会出现这种情况吗?
