文件上传不能在Win phone 8 3G连接上使用 [英] File uploading not working on Win phone 8 3G connection

问题描述

我有一个应用程序，用户可以在其中记录视频和api将录制的视频上传到天蓝。我使用下面的代码

  HttpClientHandler handler = new HttpClientHandler（）; 
 handler.MaxRequestContentBufferSize = int.MaxValue; 
 using（HttpClient httpClient = new HttpClient（handler）
 {
 MaxResponseContentBufferSize = int.MaxValue 
}）
 {
 MultipartFormDataContent content = new MultipartFormDataContent（） ; 
 content.Add（new ByteArrayContent（chunks），file，fileName）; 
 HttpResponseMessage response = null; 
 response = await httpClient.PostAsync（new Uri（url），content）; 
返回等待response.Content.ReadAsStringAsync（）; 
 
 
 
 $ b $ p 
 $ b 
这只有当连接是wifi或3G视频小于10秒当我试图上传大小约20-30 MB的视频比失败。作为回应，我得到了状态代码404 Not Found。
 
 
 
我也尝试了另一种上传方式，但遇到同样的错误。
 
 
I have a app in which user can record video and an api to upload recorded video to azure. I am using below code
HttpClientHandler handler = new HttpClientHandler();
handler.MaxRequestContentBufferSize = int.MaxValue;
using (HttpClient httpClient = new HttpClient(handler) 
   { 
        MaxResponseContentBufferSize = int.MaxValue
   })
{
  MultipartFormDataContent content = new MultipartFormDataContent();
  content.Add(new ByteArrayContent(chunks), "file", fileName);
  HttpResponseMessage response = null;
  response = await httpClient.PostAsync(new Uri(url), content);
  return await response.Content.ReadAsStringAsync();
}
This is working only when either connection is wifi or on 3G video is less than of 10 sec. When I tried to upload video of size around 20-30 MB than it fails. In response I got status code 404 Not Found.

I also tried another way to upload but caught same error.
解决方案
At last, I have changed my api code and send request with 1 mb chunks.
