HttpClient 不返回 Content-Type

Question

I'm sending a request with HttpClient . Server returns two headers which I want return to client. I run it like this:

 using (var client = new HttpClient())
 {
     var response = await client.GetAsync(DownloadUri + $"?path={path}&fileName={fileName}");
     // ...
 }

But on client side I have 10 headers, while server sends 12. This is what I get in debugger for response.Headers.ToString() :

Transfer-Encoding: chunked
X-SourceFiles: =?UTF-8?B?QzpcVXNlcnNcQWxleFxEb2N1bWVudHNcdGZzXFVDRktcdnNuXGRldlxMYW5pdC5VQ0ZLLkZpbGUuU2VydmVyXEZpbGUuc3ZjXERvd25sb2Fk?=
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST, GET, OPTIONS
Access-Control-Allow-Credentials: true
Cache-Control: private

And this is what I get with external Rest client:

Content-Type and Content-Disposition are missing. How can I get it with HttpClient ?

Answer 1

You should look at response.Content.Headers you should find headers relating to the content here. More information about all the content header types can be found on the msdn link below.

https://msdn.microsoft.com/en-us/library/system.net.http.headers.httpcontentheaders(v=vs.118).aspx

Answer 2

Content_type is part of the Content Headers. So you should use:

response.Content.Headers;

Answer 3

  HttpResponseMessage response = await client.SendAsync(request);
  String sContentType = response.Content.Headers.ContentType.MediaType;
  Console.WriteLine($"Response ContentType: {sContentType}");
  //
  // Response ContentType: application/json
