帮助这个特定的服务器端php代码我不知道php，我必须从android上传三个图片到这个php页面。
我尝试了很多方法并进行了搜索，但没有教程或任何东西不能帮助我的android代码正常工作。DNS也已配置，但服务器端不显示图像。请帮助我使用Java代码。
PHP:
<?php

header("HTTP/1.1 400 Bad Request");
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}

最佳答案
看起来你的php是正确的。
在您的设备上使用http post request和MultipartEntity数据类型。阅读更多here

我的链接示例：
您必须下载其他库才能运行MultipartEntity！
1）从http://james.apache.org/download.cgi#Apache_Mime4J下载httpcomponents-client-4.1.zip并将apache-mime4j-0.6.1.jar添加到项目中。
2）从http://hc.apache.org/downloads.cgi下载httpcomponents-client-4.1-bin.zip，并将httpclient-4.1.jar、httpcore-4.1.jar和httptime-4.1.jar添加到项目中。
3）使用下面的示例代码。 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; } }
