接受上传的PHP代码

<?php

    $friend_id = $_REQUEST['friend_id'];
    $userid = $_REQUEST['userid'];

    echo 'friend_id : '.$friend_id. ' userid '.$userid;

    move_uploaded_file($_FILES['uploadedfile']['tmp_name'], "./uploads/".$_FILES["uploadedfile"]["name"]);

?>

你想上传多个大型内容，对吗？我只是clarefyingYes，服务器已经完成了，但在Android中，我们将拍摄一些照片、视频或音频，然后上传到服务器。因此我采用了与我发布的问题解决方案类似的方法。但我必须添加3个库才能“正常工作”“，但我达到了移动到

Android Studio

的极限，希望我能。。。但不在我手中。大老板不想把项目转移到它身上。。（多次试图说服..buuuuutt…不走运）谢谢@ArsalImam我会试试告诉你一些事情只问一个问题，“jsonString”是什么？我的意思是，我不知道从哪里获得它，或者它代表了什么（对不起，在这种类型的服务器中有点新手）。实际上，兄弟，这种方法涵盖了android和服务器之间的主要功能，你可以设置jsonString=”“m。。我被绊倒了。。正在启动此错误：09-10 14:09:28.160:E/AndroidRuntime（11166）：java.lang.NoSuchFieldError:没有类型为Lorg/apache/http/message/BasicHeaderValueFormatter的静态字段实例；Lorg/apache/http/message/BasicHeaderValueFormatter类中；或者它的超类（声明'org.apache.http.message.BasicHeaderValueFormatter'出现在/system/framework/ext.jar中）是您正在使用的库问题。。。。！如何在其中添加进度条。。？
