从Android在php服务器上上传多个图像
作者：互联网
对于此特定服务器端php代码的帮助我不了解php,因此我必须将三个图像从android上传到该php页面.
我尝试了许多方法并进行了搜索,但是没有教程或任何内容都无法帮助我,我的Android代码可以正常工作. DNS也已配置,但服务器端未显示图像.请帮我用Java代码.
PHP：
<?php
if ($_FILES["file1"]["error"] > 0)
{
header("HTTP/1.1 400 Bad Request");
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else if ($_FILES["file2"]["error"] > 0)
{
header("HTTP/1.1 400 Bad Request");
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else if ($_FILES["file3"]["error"] > 0)
{
header("HTTP/1.1 400 Bad Request");
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else
{
if ($_FILES["file1"]["error"] > 0)
{
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file1"]["name"] . "<br />";
echo "Type: " . $_FILES["file1"]["type"] . "<br />";
echo "Size: " . ($_FILES["file1"]["size"] / 1024) . " Kb<br />";
echo "Stored in: " . $_FILES["file1"]["tmp_name"]. "<br />";
}
//$target_path = "uploads/";
$target_path = "elp/pendingimages/";
$target_path = $target_path . basename( $_FILES['file1']['name']);
if(move_uploaded_file($_FILES['file1']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['file1']['name']).
" has been uploaded";
}

Java：
public class TryprojectActivity extends Activity {

int pic_count = 0;

@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
try {

解决方法:
看起来您的PHP是正确的.
在您的设备上,使用具有MultipartEntity数据类型的HTTP POST请求.阅读更多here

我的链接示例：
您将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添加到您的项目中.
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httpmime-4.1.jar添加到您的项目中.
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;
}
}
