我使用此代码将文件上传到本地服务器（wamp服务器）并且它可以工作，但是当我更改连接到远程Web服务器的目标时，代码没有显示任何错误，并且过程进展顺利但我可以找不到服务器中的文件。 请帮帮我..
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 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog1.dismiss();
Log.e("uploadFile", "Source File not exist");
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(UploadAssignment.this, "Source File not exist",Toast.LENGTH_SHORT).show();
}
});
return 0;
}

使用Below功能在服务器上传文件，
private void doFileUpload() {
File file1 = new File(selectedPath1);
File file2 = new File(selectedPath2);
File file3 = new File(selectedPath3);
File file4 = new File(selectedPath4);
String urlString = "your server link/folder_name/filename.php";
try {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(urlString);
FileBody bin1 = new FileBody(file1);
FileBody bin2 = new FileBody(file2);
FileBody bin3 = new FileBody(file3);
FileBody bin4 = new FileBody(file4);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("uploadedfile1", bin1);
reqEntity.addPart("uploadedfile2", bin2);
reqEntity.addPart("uploadedfile3", bin3);
reqEntity.addPart("uploadedfile4", bin4);
reqEntity.addPart("user", new StringBody("User"));
post.setEntity(reqEntity);
HttpResponse response = client.execute(post);
resEntity = response.getEntity();
final String response_str = EntityUtils.toString(resEntity);
if (resEntity != null) {
Log.i("RESPONSE", response_str);
runOnUiThread(new Runnable() {
public void run() {
try {
Toast.makeText(
getApplicationContext(),
"Upload Complete. Check the server uploads directory.",
Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
} catch (Exception ex) {
Log.e("Debug", "error: " + ex.getMessage(), ex);
}
}
