如何使HttpClient忽略Content-Length标头

Question

我正在使用HttpClient与我无法访问的服务器进行通信.有时,服务器的JSON响应会被截断.

当Content-Length标头小于它应该是(8192对8329)时,会出现问题.这似乎是服务器上的一个错误,它提供了比响应主体的实际大小更小的Content-Length标头.如果我使用谷歌浏览器而不是HttpClient,则响应始终完成.

因此,我想让HttpClient忽略错误的Content-Length标头并读取到响应的结尾.有可能吗？任何其他解决方案都很受欢迎.谢谢!

这是我的HttpClient的代码:

var client = new HttpClient();
client.BaseAddress = new Uri(c_serverBaseAddress);

HttpResponseMessage response = null;
try
{
      response = await client.GetAsync(c_serverEventApiAddress + "?location=" + locationName);
}
catch (Exception e)
{
    // Do something
}
var json = response.Content.ReadAsStringAsync().Result;

var obj = JsonConvert.DeserializeObject<JObject>(json); // The EXCEPTION occurs HERE!!! Because the json is truncated!

编辑1:

如果我使用HttpWebRequest,它可以完全读取到JSON响应的末尾而不会截断.但是,我想使用HttpClient,因为它有更好的async/await.

这是使用HttpWebRequest的代码:

var url = c_serverBaseAddress + c_serverEventApiAddress + "?location=" + "Saskatchewan";

var request = (HttpWebRequest)WebRequest.Create(url); 
request.ProtocolVersion = HttpVersion.Version10;
request.Method = "GET";
request.ContentType = "application/x-www-form-urlencoded";

var response = (HttpWebResponse)request.GetResponse();

StringBuilder stringBuilder = new StringBuilder(); 
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
      string line;
      while ((line = reader.ReadLine()) != null)
      {
            stringBuilder.Append(line);
      }
}
var json = stringBuilder.ToString();  // COMPLETE json response everytime!!!

您可以尝试指定响应内容的缓冲区大小

var client = new HttpClient();
client.MaxResponseContentBufferSize = <your_buffer_size>;

其中属性 MaxResponseContentBufferSize 的含义是：

获取或设置读取响应内容时要缓冲的最大字节数。
