Android :使用MultipartEntity上传大型文件

Question

根据这个答案，"Android upload video to remote server using HTTP multipart form data"，我做了所有步骤。

但是我不知道我是如何为服务器端编码的！我的意思是一个PHP简单的页面，为我最忠实的敌人上传服务。

另一个问题是: YOUR_URL (以下代码段的第3行)必须是该PHP页面的地址？

private void uploadVideo(String videoPath) throws ParseException, IOException {

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(YOUR_URL);

    FileBody filebodyVideo = new FileBody(new File(videoPath));
    StringBody title = new StringBody("Filename: " + videoPath);
    StringBody description = new StringBody("This is a description of the video");

    MultipartEntity reqEntity = new MultipartEntity();
    reqEntity.addPart("videoFile", filebodyVideo);
    reqEntity.addPart("title", title);
    reqEntity.addPart("description", description);
    httppost.setEntity(reqEntity);

    // DEBUG
    System.out.println( "executing request " + httppost.getRequestLine( ) );
    HttpResponse response = httpclient.execute( httppost );
    HttpEntity resEntity = response.getEntity( );

    // DEBUG
    System.out.println( response.getStatusLine( ) );
    if (resEntity != null) {
      System.out.println( EntityUtils.toString( resEntity ) );
    } // end if

    if (resEntity != null) {
      resEntity.consumeContent( );
    } // end if

    httpclient.getConnectionManager( ).shutdown( );
}

Answer 1

这段代码正常工作，我应该使用的PHP代码非常简单：

<?php

    $file_path = "uploads/";

    $file_path = $file_path . basename( $_FILES['videoFile']['name']);
    if(move_uploaded_file($_FILES['videoFile']['tmp_name'], $file_path)) {
        echo "success";
    } else{
        echo "upload_fail_php_file";
    }
 ?>

注意到，videoFile必须与

reqEntity.addPart("videoFile", filebodyVideo);

而最重要的问题可能是服务器配置中post_max_size和upload_max_filesize的默认值！由于缺省值太小，并且当您试图上传大型文件时，PHP脚本将返回："upload_fail_php_file“，没有错误或异常抛出。所以记住把这些值设置得足够大..。

享受编码吧。
