HTTP in Java socket


HTTP in Java socket



I want to send a JSON to an already written server (not from me).
My problem is that I have an HTTP problem and need to convert it to HTTP.



Server message:


2018-06-29 20:02:30.532:WARN:oejh.HttpParser:qtp245475541-15: badMessage: 400
No URI for HttpChannelOverHttp@2bb4ec27{r=0,c=false,a=IDLE,uri=}
2018-06-29 20:03:24.206:WARN:oejh.HttpParser:qtp245475541-18: badMessage: 400
No URI for HttpChannelOverHttp@866a0c9{r=0,c=false,a=IDLE,uri=}



Code:


public class client {

public static void main(String args) {
JsonObject js = new JsonObject();
js.addProperty("action","auth");
js.addProperty("type","android");
js.addProperty("token","lalalalalalalalala");
try {
Socket ss = new Socket("localhost",3000);
PrintWriter out =
new PrintWriter(ss.getOutputStream(), true);
BufferedReader in =
new BufferedReader(
new InputStreamReader(ss.getInputStream()));
out.println(js.toString());// sending json

System.out.println(in.readLine()); //recieving answer

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}



Output on console: HTTP/1.1 400 No URI.


HTTP/1.1 400 No URI





Don't use a Socket, use an HttpURLConnection.

Socket

Writing your own HTTP client from scratch is doable, but it's not simple. Check out this link: Java Tutorials: URLConnection. That is going to save you a lot of effort.

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
