Android上传图片到PHP服务器并且支持浏览器上传文件（word、图片、音乐等）

暑假已经过了一半了，这才完成计划当中的第二个任务。虽然进度是慢了点。但也算是暑假的收获吧。下面我就把我学习当中的收获记录在此。

还是跟以往一样，先上图片。

操作的步骤：打开程序----》选择上传的照片-----》点击返回键------》显示没有选择上传图片的toast------》点击上传的图片-----》打印图片的存储的物理路径----》询问是否确认上传选择的图片-----》确认则显示上传成功----》取消则退出

php代码：

<?php
//上传文件进行简单错误过滤
if($_FILES['userfile']['error']>0){
    exit('上传文件有错误');
    }
    //定义存放文件的真实路径（需要手动创建）
    $path = "D:/xampp/htdocs/xampp/upload/";
    //定义存放上传文件的真实路径名
    $name = $_FILES['userfile']['name'];
    
    //将文件的名字的字符编码从utf-8转换成gb2312
    $name = iconv ("UTF-8","GB2312",$name);
    //将上传文件移动到指定目录文件中
    $path = $path.$name;
    if(move_uploaded_file($_FILES['userfile']['tmp_name'],$path)){
        echo "文件上传成功！";
        // print_r($_FILES);

        }else{
        echo "文件上传失败！";
       $_FILES['userfile']['tmp_name'] ;
        print_r($_FILES);

            }
?>

    private void doUpload(){
        new Thread(new Runnable(){
            public void run(){
                try{
                    //文件二进制数据
                    InputStream in = new FileInputStream(new File(pathName));

                        }
                    });

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.btn_select = (Button) this.findViewById(R.id.btn_select);
        this.btn_select.setOnClickListener(new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(intent, FLAGE_LOAD_IMAGE);
            }
        });
    }

   
    
}

UserService.java 一个接口代码为：

package com.itcast.upload;

import java.io.InputStream;
import java.util.Map;

public interface UserService {
    public String userUpload(InputStream in,Map<String,String> data)throws Exception;
}

UserServiceImpl.java 实现UserService接口

代码为：

package com.itcast.upload;

import java.io.InputStream;
import java.nio.charset.Charset;
import java.util.Map;
import java.util.Random;

import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.InputStreamBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.protocol.HTTP;
import org.apache.http.util.EntityUtils;

 class UserServiceImpl implements UserService {

    @Override
    public String userUpload(InputStream in, Map<String, String> data)
            throws Exception {
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("http://192.168.1.103/xampp/upData.php");
        //要把数据封装到post里面去
        /*Httpmine*/
        MultipartEntity entity = new MultipartEntity();
        //二进制的流文件数据对象
        entity.addPart("userfile",new InputStreamBody(in, "multipart/form-data",MainActivity.pathName));
        //数据放到post
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        int statusCode = response.getStatusLine().getStatusCode();
        System.out.println(statusCode);
        if (statusCode != HttpStatus.SC_OK) {
            
        }
        String result = EntityUtils.toString(response.getEntity(), HTTP.UTF_8);
        return result;
    }

}

需要添加的权限有：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET"/>

至此，android端的代码书写完毕。

下面是浏览器端的代码：
