帖子文件从Android的服务器 - MultipartEntityBuilder - HTTP [英] Post files to server from Android - MultipartEntityBuilder - HTTP

问题描述

我想上传一些文件到我的服务器（通过HTTP POST）从一个Android应用程序，我在这里检查过很多问题，但不能让它开始工作。我希望有人能帮助我了：

I am trying to upload some files to my server (via HTTP POST) from an Android app and I have checked many Questions here but can't get it to work. I hope someone can help me out:

我还包含在URL中的一些变量来验证至少那些到达服务器（GET）。

I also included some variables in the URL to verify that at least those are reaching the server(GET).

    HttpClient httpClient = new DefaultHttpClient();
    String url="http://XXXXX.com/files/upload.php?flies=yes&eats=no&friend=yes";
    HttpPost httppost = new HttpPost(url);
    httppost.addHeader("Content-Type", "multipart/form-data");
    String content,response="";
    try {

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        builder.addTextBody("randomvar", "42");

        //add image file
        //String filename="eye.png";
        //InputStream is=mContext.getAssets().open(filename);
        //builder.addBinaryBody("image", is, ContentType.create("image/png"), filename);

        //add text XML file
        final File file = new File(mContext.getFilesDir() +"/"+"serverXML.xml");
        FileBody fb = new FileBody(file);
        builder.addPart("file", fb);
        httppost.setEntity(builder.build());


        response = EntityUtils.toString(httpClient.execute(httppost).getEntity(), "UTF-8");


        Log.i(TAG, "RESPONSE FROM SERVER: "+response);
    } catch (IOException e) {
        Log.i(TAG, "Exception: "+response);
        e.printStackTrace();
    }

这不运行，并从服务器的响应。以下是$ _GET，$ _ POST的vardump，$ _FILES：

This does run and get a response from the server. The following is the vardump of $_GET, $_POST, $_FILES:

我想POST有文件和可变

I would want POST to have the file and variable

在我的Eclipse的logcat我看到使用MultiPartEntityBuilder后的情况如下：

In my Eclipse Logcat I see the following after using MultiPartEntityBuilder:

10-06 02:36:57.231: D/dalvikvm(15888): DexOpt: couldn't find static field Lorg/apache/http/message/BasicHeaderValueParser;.INSTANCE

10-06 02:36:57.241: W/dalvikvm(15888): VFY: unable to resolve static field 5960 (INSTANCE) in Lorg/apache/http/message/BasicHeaderValueFormatter;

我想我已经正确包含所有需要的库：

I think I have correctly included all the required libraries:

I was able to solve this, my solution is the described in my answer below

推荐答案

我很幸运地找到一个<一个href="http://stackoverflow.com/questions/20284542/upload-photo-using-httppost-multipartentitybuilder">Answer由克里斯蒂安在＃1就解决了我的问题。

I was fortunate enough to find one Answer by Krystian in Stackoverflow that solved my issue.

添加边界后，它开始工作。我不得不将它添加到相应的HTTP POST

After adding the boundary it started working. I had to add it to the HTTP Post

String boundary = "-------------" + System.currentTimeMillis();
httppost.setHeader("Content-type", "multipart/form-data; boundary="+boundary);

和该实体

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
builder.setBoundary(boundary);

现在我得到的一切，在服务器：

Now I get everything in the server:
