如何让 HttpClient 忽略 Content-Length 标头

Question

I am using HttpClient to communicate with a server which I don't have access to. Sometimes the JSON response from the server is truncated.

The problem occurs when the Content-Length header is smaller than what it should be (8192 vs. 8329). It seems like a bug on the server which gives a smaller Content-Length header than the actual size of the response body. If I use Google Chrome instead of HttpClient, the response is always complete.

Therefore, I want to make HttpClient to ignore the wrong Content-Length header and read to the end of the response. Is it possible to do that? Any other solution is well appreciated. Thank you!

This is the code of my HttpClient:

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!

EDIT 1:

If I use HttpWebRequest, it can read to the end of the JSON response completely without any truncation. However, I would like to use HttpClient since it has better async/await.

This is the code using HttpWebRequest:

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!!!

You could try specifying the buffer size of the response content

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

Where the property MaxResponseContentBufferSize means:

Gets or sets the maximum number of bytes to buffer when reading the response content.
