从Android发布文件到服务器 - MultipartEntityBuilder - HTTP

Question

我试图从Android应用程序上传一些文件到我的服务器(通过HTTP POST),我在这里检查了很多问题,但无法让它工作.我希望有人可以帮助我:

我还在URL中包含了一些变量,以验证至少那些变量到达服务器(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();
    }

这确实运行并从服务器获得响应.以下是$ _GET,$ _POST,$ _FILES的vardump:

我希望POST有文件和变量

在我的Eclipse Logcat中,我在使用MultiPartEntityBuilder后看到以下内容:

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 5966 (INSTANCE) in Lorg/apache/http/message/BasicHeaderValueParser;

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

我想我已经正确地包含了所有必需的库:

我能够解决这个问题,我的解决方案在下面的答案中有所描述

Answer 1

我很幸运能在Stackoverflow中找到克里斯蒂安的一个答案来解决我的问题.

添加边界后,它开始工作.我不得不将它添加到HTTP Post

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

和实体

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

现在我得到服务器中的所有内容:
