使用httppost Android文件上传 [英] file upload using httppost android
问题描述
我已经试过很多方法和对堆栈溢出和其他博客描述上传从我的Android应用程序文件到我的服务器的答案,但他们没有为我工作。
I have tried so many methods and answers that described on stack overflow and other blogs for uploading a file from my android app to my server but none of them worked for me.
我用httpclient4.3.3.jar,httpcore4.3.3.jar和httpmime4.3.3.jar
I used httpclient4.3.3.jar,httpcore4.3.3.jar and httpmime4.3.3.jar
我没有得到任何错误消息和我的应用程序工作的罚款。但没有数据即将在我的服务器,我使用PHP的服务器和我的服务器端code是波纹管。
Am not getting any error messages and my app working fine. But not data coming in my server, am using php server and my server side code is bellow.
$file_path = "uploads/";
$file_path = $file_path.basename( $_FILES['file_data']['name']);
if(move_uploaded_file($_FILES['file_data']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
请给我任何工作样品或code所需的库。这么多天我的工作就可以了..请帮我一个完整的答案。
please give me any working samples or code with required libs. So many days am working on it.. please help me with a complete answer.
推荐答案
试试这个。
public int uploadFile(String sourceFileUri) {
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"
+uploadFilePath + "" + uploadFileName);
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Source File not exist :"
+uploadFilePath + "" + uploadFileName);
}
});
return 0;
}
else
{
