C# HttpClient Post 无法获得完整响应

Question

我在从发布请求中获得完整响应时遇到问题。 具体来说，我的问题是在 Fiddler 中我得到了完整的响应（下面的响应），而在 .NET 中我只得到了一部分。

我正在使用 HttpClient，这就像我的代码一样

        var client = new HttpClient();

        var response = client.PostAsync(url, content).Result;

在 .NET 中我得到了这个响应（序列化为 json）

{"Version":{"Major":1,"Minor":1,"Build":-1,"Revision":-1,"MajorRevision":-1,"MinorRevision":-1},"Content":{"Headers":[{"Key":"Content-Length","Value":["471"]},{"Key":"Expires","Value":["Thu, 19 Nov 1981 08:52:00 GMT"]},{"Key":"Content-Type","Value":["application/json; charset=UTF-8"]}]},"StatusCode":200,"ReasonPhrase":"OK","Headers":[{"Key":"X-Frame-Options","Value":["SAMEORIGIN"]},{"Key":"Pragma","Value":["no-cache"]},{"Key":"Cache-Control","Value":["no-store, must-revalidate, no-cache, post-check=0, pre-check=0"]},{"Key":"Date","Value":["Wed, 19 Apr 2017 22:13:15 GMT"]},{"Key":"Set-Cookie","Value":["SD_FRAMEWORK_SESSION=10ktfgcedl5rq427kvmo0sj7v4; path=/","user=abca7451088; expires=Sat, 20-May-2017 22:13:15 GMT; Max-Age=2678400; httponly","password=d30b0cc02736cf891cfca885ff5245bd; expires=Sat, 20-May-2017 22:13:15 GMT; Max-Age=2678400; httponly"]},{"Key":"Server","Value":["Apache"]},{"Key":"Connection","Value":["close"]}],"RequestMessage":{"Version":{"Major":1,"Minor":1,"Build":-1,"Revision":-1,"MajorRevision":-1,"MinorRevision":-1},"Content":{"Headers":[{"Key":"Content-Type","Value":["application/x-www-form-urlencoded"]},{"Key":"Content-Length","Value":["88"]}]},"Method":{"Method":"POST"},"RequestUri":"http://URL.COM/","Headers":[],"Properties":{}},"IsSuccessStatusCode":true}

但在 Fiddler 中我得到了这个响应（在 RAW 视图中）

那么，我怎样才能在 .NET 响应中获得那个特殊部分（“{“special”：{“....”）？

Fiddler 显示响应内容。您可以使用HttpContent 的ReadAsStringAsync 方法从HttpResponseMessage 获取内容：

var content = response.Content.ReadAsStringAsync().Result;
