MultipartEntity图像不被上传 [英] MultipartEntity image is not upload

问题描述

我想用MultipartEntity上传图片。我有尝试以下code。

我没有得到任何错误，但图像没有上传。我有足够的权限，上传

PHP

 ＆LT; PHP    //接收来自Android的数据
    $名称= $ _ POST ['名'];
    $数据= $ _ POST ['数据'];    //接收文件
    $文件= $ _FILES ['形象']    move_uploaded_file（$ _ FILES ['形象'] ['tmp_name的值']，User_files /\".$_ FILES ['形象'] ['名']）;
    //处理数据    //返回响应于服务器    回声json_en code（
                阵列（
                    '结果'= GT;'成功'，
                    '味精'=＆GT;报告添加成功。
                    ）
                ）;                ？＆GT;公共无效上传（）抛出异常{
        //服务器的网址
        字符串URL =URL;
        HttpClient的客户端=新DefaultHttpClient（）;
        HttpPost后=新HttpPost（URL）;
        MultipartEntity mpEntity =新MultipartEntity（）;
        //文件的路径上传
        字符串的文件路径= Environment.getExternalStorageDirectory（）+/ a.png;
        档案文件=新的文件（文件路径）;
        ContentBody cbFile =新FileBody（文件，图像/ *）;        //将数据添加到多部分实体
        mpEntity.addPart（形象，cbFile）;
        mpEntity.addPart（名，新StringBody（测试，Charset.forName（UTF-8）））;
        mpEntity.addPart（数据，新StringBody（这是测试报告，Charset.forName（UTF-8）））;
        post.setEntity（mpEntity）;
        //执行POST请求
        HTT presponse response1 = client.execute（岗位）;
        //从服务器的响应
        HttpEntity resEntity = response1.getEntity（）;
        字符串响应= EntityUtils.toString（resEntity）;
        Log.d（响应：响应）;
        //生成从响应该阵列
        JSONArray jsonarray =新JSONArray（[+响应+]）;
        的JSONObject的JSONObject = jsonarray.getJSONObject（0）;
        //从响应结果变量
        字符串结果=（jsonobject.getString（结果））;
        弦乐味精=（jsonobject.getString（味精））;
        //关闭连接
        client.getConnectionManager（）shutdown（）方法。
    }
 

解决方案

您需要赋予权限在manifest文件的 WRITE_EXTERNAL_STORAG​​E 和 READ_EXTERNAL_STORAG​​E ：

 ＆LT;使用许可权的android：NAME =android.permission.WRITE_EXTERNAL_STORAG​​E/＆GT;   ＆LT;使用许可权的android：NAME =android.permission.READ_EXTERNAL_STORAG​​E/＆GT;
 

I want to upload image using MultipartEntity. I have try below code.

I did not get any error but image is not upload. I have enough permission for upload

PHP

<?php

    //Receive the data from android
    $name = $_POST['name'];
    $data = $_POST['data'];

    //Receive the file
    $file = $_FILES['image']

    move_uploaded_file($_FILES['image']['tmp_name'], "User_files/".$_FILES['image']['name']);
    //process the data

    //return response to the server

    echo json_encode(
                array(
                    'result'=>'success',
                    'msg'=>'Report added successfully.'
                    )
                );

                ?>

public void upload() throws Exception {
        //Url of the server
        String url = "URL";
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(url);
        MultipartEntity mpEntity = new MultipartEntity();
        //Path of the file to be uploaded
        String filepath = Environment.getExternalStorageDirectory()+"/a.png";
        File file = new File(filepath);
        ContentBody cbFile = new FileBody(file, "image/*");         

        //Add the data to the multipart entity
        mpEntity.addPart("image", cbFile);
        mpEntity.addPart("name", new StringBody("Test", Charset.forName("UTF-8")));
        mpEntity.addPart("data", new StringBody("This is test report", Charset.forName("UTF-8")));
        post.setEntity(mpEntity);
        //Execute the post request
        HttpResponse response1 = client.execute(post);
        //Get the response from the server
        HttpEntity resEntity = response1.getEntity();
        String Response=EntityUtils.toString(resEntity);
        Log.d("Response:", Response);
        //Generate the array from the response
        JSONArray jsonarray = new JSONArray("["+Response+"]");
        JSONObject jsonobject = jsonarray.getJSONObject(0);
        //Get the result variables from response 
        String result = (jsonobject.getString("result"));
        String msg = (jsonobject.getString("msg"));
        //Close the connection
        client.getConnectionManager().shutdown();
    }

解决方案

You need to give permission in your manifest file for WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE:

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

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