Question

我将Android Java App移植到C＃，Windows商店应用程序。它必须向具有多部分内容，图像和一些键/值数据的服务器发送POST。 java代码：

HttpPost post = new HttpPost(SERVER);
        MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
        entity.addPart(filename, new ByteArrayBody(byteArray, "image/jpeg", filename + ".jpg"));
        entity.addPart("usr", new StringBody(user));
        entity.addPart("sid", new StringBody(session));
        entity.addPart("action", new StringBody(method));
        post.setEntity(entity);

和Windows应用商店代码：

  MultipartFormDataContent multipartContent = new MultipartFormDataContent();
        ByteArrayContent byteContent = new ByteArrayContent(byteArray);
        multipartContent.Add(byteContent, fileName);                
        multipartContent.Add(new StringContent(User), "usr");
        multipartContent.Add(new StringContent(Session), "sid");
        multipartContent.Add(new StringContent(method), "action");

但服务器响应不同的响应。它可能是什么？

如果服务器通过user-agent确定输出，则尝试在两个Apps上设置相同的UserAgent。

http://developer.android.com/reference/android/net/http/AndroidHttpClient.html

// UserAgent taken from http://www.useragentstring.com/pages/Android%20Webkit%20Browser/
// Pick one you find suitable or use Firefox/Chrome UserAgents, whatever works for you
String userAgent = "Mozilla/5.0 (Linux; U; Android 2.3.4; fr-fr; HTC Desire Build/GRJ22) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1";
AndroidHttpClient httpClient = AndroidHttpClient.getInstance(userAgent);
httpClient.execute(post);

C＃/。NET

// make sure to use same user agent in both apps
string userAgent = "Mozilla/5.0 (Linux; U; Android 2.3.4; fr-fr; HTC Desire Build/GRJ22) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1";
HttpClient httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Add("user-agent",userAgent);

如果服务器根据用户代理标头返回不同的结果，那么应该给出相同的结果。

Windows商店应用发布与multipartFormDataContent
