我在使用Android + Php将MP3文件上传到服务器时遇到问题
正在使用android studio
上载完成后，一切正常，我无法在服务器端找到文件

我的布局代码:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

android:layout_height="match_parent"
tools:context="com.uploadfile.milad.MainActivity">


<Button
    android:id="@+id/upload"
    android:layout_centerInParent="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

            // sees the explanation, try again to request the permission.

        } else {

            // result of the request.
        }
    }
}

}

我的上传类(class):

package com.uploadfile.milad;

import android.content.Context;
import android.content.pm.PackageInfo;
import android.location.Address;
import android.util.Log;

import com.loopj.android.http.AsyncHttpClient;
import com.loopj.android.http.RequestParams;
import com.loopj.android.http.ResponseHandlerInterface;

import java.io.File;
import java.io.FileNotFoundException;

import cz.msebera.android.httpclient.client.ResponseHandler;



public class Upload {

private static String URL = "http://10.0.2.2:8000/edsa-proj/test%20lab/up/upload.php", KEY = "uploaded_file";
private String fileAddress;
private File file;

private AsyncHttpClient httpClient;
private Context context;
private RequestParams params;

public Upload(Context context, String FileAddress){
    this.fileAddress = FileAddress;
    this.context = context;
    httpClient = new AsyncHttpClient();
    params = new RequestParams();
    file  = new File(FileAddress);
}

public boolean fileExist(){
    if(file.exists())
        return true;
    else
        return false;
}
/*returns
   true if file is exist
   false if file not exist
* */
public boolean run(ResponseHandlerInterface handler){
    if(putFileParam(file)) {
        httpClient.post(context, URL, params, handler);
        return true;
    }
    else {
        return false;
    }
}
/*returns
   true if file is exist
   false if file not exist
* */
private boolean putFileParam(File file)
{
    try {
        params.put(KEY, file);
        return true;
    }
    catch(Exception e) {
        Log.w("LOG_UPLOAD", e.toString());
        return false;
    }
}
}

和php代码:

<?php

$file_path = "uploads/";
$KEY = 'uploaded_file';
$file_path = $file_path . basename( $_FILES[$KEY]['name']);

if(move_uploaded_file($_FILES[$KEY]['tmp_name'], $file_path)) {
    echo "success";
} else{
    echo "fail";
}
 ?>

我用替换字符串只是为了测试
我的问题是上载完成后我选择文件时，在笨蛋上载时找不到mp3文件
我不知道问题出在哪里
提前thnx

如果您对要上传的文件的绝对路径进行硬编码，则您的代码是正确的。工作正常。

除了在此处使用绝对路径之外，您的代码和逻辑还可以(但是解决这个问题可能很小)。结论是:您面临的问题与服务器配置有关。我建议您调查一下用户帐户，权限和权限(上传文件，编写服务器端)背后的内容。如果有问题，请在StackOverflow此处提出另一个问题。本礼物已经完成。
