本文介紹了從android在php服務器上上傳多個圖像的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！

問題描述

此特定服務器端 php 代碼的幫助我對 php 一無所知，我必須將三張圖片從 android 上傳到此 php 頁面.

我嘗試了很多方法并進行了搜索，但沒有任何教程或任何內容對我沒有幫助，我的 android 代碼運行正常.DNS 也已配置，但圖像未顯示在服務器端.請幫我寫java代碼.

PHP:

解決方案

看起來你的 PHP 是正確的.

在您的設備上使用帶有 MultipartEntity 數據類型的 HTTP POST 請求.閱讀更多此處

編輯

來自我的鏈接的示例:

您必須下載額外的庫才能運行 MultipartEntity！

1) 從 http://james.apache 下載 httpcomponents-client-4.1.zip.org/download.cgi#Apache_Mime4J 并將 apache-mime4j-0.6.1.jar 添加到您的項目中.

2) 從 http://hc.apache 下載 httpcomponents-client-4.1-bin.zip.org/downloads.cgi 并將 httpclient-4.1.jar、httpcore-4.1.jar 和 httpmime-4.1.jar 添加到您的項目中.

3) 使用下面的示例代碼.

<前><代碼>私有 DefaultHttpClient mHttpClient;公共服務器通信(){HttpParams params = new BasicHttpParams();params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);mHttpClient = new DefaultHttpClient(params);}public void uploadUserPhoto(File image1, File image2, File image3) {嘗試 {HttpPost httppost = new HttpPost("some url");MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);multipartEntity.addPart("Title", new StringBody("Title"));multipartEntity.addPart("Nick", new StringBody("Nick"));multipartEntity.addPart("Email", new StringBody("Email"));multipartEntity.addPart("Description", new StringBody(Settings.SHARE.TEXT));multipartEntity.addPart("file1", new FileBody(image1));multipartEntity.addPart("file2", new FileBody(image2));multipartEntity.addPart("file3", new FileBody(image3));httppost.setEntity(multipartEntity);mHttpClient.execute(httppost, new PhotoUploadResponseHandler());} 捕獲(異常 e){Log.e(ServerCommunication.class.getName(), e.getLocalizedMessage(), e);}}私有類 PhotoUploadResponseHandler 實現了 ResponseHandler {@覆蓋公共對象 handleResponse(HttpResponse 響應)拋出 ClientProtocolException，IOException {HttpEntity r_entity = response.getEntity();String responseString = EntityUtils.toString(r_entity);Log.d("上傳", responseString);返回空；}}

Help for this specific server side php code I don't have any knowledge of php and I have to upload three images from android to this php page.

I have tried many methods and searched for it but no tutorial or anything didn't help me my android code is working properly. DNS also configured but images aren't shown at the server side. Please help me with java code.

解決方案

Looks like your PHP is correct.

On your device use HTTP POST request with MultipartEntity data type. Read more here

EDIT

Example from my link:

You will have to download additional libraries to get MultipartEntity running!

1) Download httpcomponents-client-4.1.zip from http://james.apache.org/download.cgi#Apache_Mime4J and add apache-mime4j-0.6.1.jar to your project.

2) Download httpcomponents-client-4.1-bin.zip from http://hc.apache.org/downloads.cgi and add httpclient-4.1.jar, httpcore-4.1.jar and httpmime-4.1.jar to your project.

3) Use the example code below.



    private DefaultHttpClient mHttpClient;


    public ServerCommunication() {
        HttpParams params = new BasicHttpParams();
        params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
        mHttpClient = new DefaultHttpClient(params);
    }


    public void uploadUserPhoto(File image1, File image2, File image3) {

        try {

            HttpPost httppost = new HttpPost("some url");

            MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);  
            multipartEntity.addPart("Title", new StringBody("Title"));
            multipartEntity.addPart("Nick", new StringBody("Nick"));
            multipartEntity.addPart("Email", new StringBody("Email"));
            multipartEntity.addPart("Description", new StringBody(Settings.SHARE.TEXT));
            multipartEntity.addPart("file1", new FileBody(image1));
            multipartEntity.addPart("file2", new FileBody(image2));
            multipartEntity.addPart("file3", new FileBody(image3));
            httppost.setEntity(multipartEntity);

            mHttpClient.execute(httppost, new PhotoUploadResponseHandler());

        } catch (Exception e) {
            Log.e(ServerCommunication.class.getName(), e.getLocalizedMessage(), e);
        }
    }

    private class PhotoUploadResponseHandler implements ResponseHandler {

        @Override
        public Object handleResponse(HttpResponse response)
                throws ClientProtocolException, IOException {

            HttpEntity r_entity = response.getEntity();
            String responseString = EntityUtils.toString(r_entity);
            Log.d("UPLOAD", responseString);

            return null;
        }

    }
