谁能告诉我这段代码有什么问题，它返回语法错误。任何人都可以修复它吗？
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name="uploaded_file";filename=""
+ fileName + """ + lineEnd);'
第二部分在 catch 它返回错误。请检查这个：
runOnUiThread(new Runnable() {
public void run() {
String msg = "File Upload Completed.\n\n See uploaded file here : \n\n"
+http://www.androidexample.com/media/uploads/"
+uploadFileName;
messageText.setText(msg);
Toast.makeText(UploadToServer.this, "File Upload Complete.",Toast.LENGTH_SHORT).show();
}
});
}
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
dialog.dismiss();
ex.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("MalformedURLException Exception : check script url.");
Toast.makeText(UploadToServer.this, "MalformedURLException",Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
dialog.dismiss();
e.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Got Exception : see logcat ");
Toast.makeText(UploadToServer.this, "Got Exception : see logcat ",Toast.LENGTH_SHORT).show();
}});
Log.e("Upload file to server Exception", "Exception : " + e.getMessage(), e);
}
dialog.dismiss();
return serverResponseCode;
} // End else block
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.upload_to_server, menu);
return true;
}
}
