看起来你的 PHP 是正确的.
在您的设备上使用带有 MultipartEntity 数据类型的 HTTP POST 请求.阅读更多此处

来自我的链接的示例:
您必须下载额外的库才能运行 MultipartEntity！
1) 从 http://james.apache 下载 httpcomponents-client-4.1.zip.org/download.cgi#Apache_Mime4J 并将 apache-mime4j-0.6.1.jar 添加到您的项目中.
2) 从 http://hc.apache 下载 httpcomponents-client-4.1-bin.zip.org/downloads.cgi 并将 httpclient-4.1.jar、httpcore-4.1.jar 和 httpmime-4.1.jar 添加到您的项目中.
3) 使用下面的示例代码.
<前><代码>私有 DefaultHttpClient mHttpClient;公共服务器通信(){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) {尝试 {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());} 捕获(异常 e){Log.e(ServerCommunication.class.getName(), e.getLocalizedMessage(), e);}}私有类 PhotoUploadResponseHandler 实现了 ResponseHandler {@覆盖公共对象 handleResponse(HttpResponse 响应)抛出 ClientProtocolException，IOException {HttpEntity r_entity = response.getEntity();String responseString = EntityUtils.toString(r_entity);Log.d("上传", 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.

解决方案
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;
}
}
