HttpURLconnection POST request

[chopficaro]

i want to send a request with post data
i tried looking it up for myself, but this page has alot of missing information
HTTP POST Basics
when i compiled it the compiler didnt know what connector.open was or httprequest was etc

[Norm]

the compiler didnt know

Please post the full text of any error messages.

Did you spell the class names and method names correctly?
Did you have the needed import statements?

[chopficaro]

i copied and pasted it exactly so everything was spelled correctly, but then i started messing with it because it wasnt working, i replaced HttpConnection with HttpURLConnection and stuff
maybe i dont have the "connector" import statement, but i cant find any class called connector
it looks like connector is an object tho and they dont show the instanciation of the class
they dont show the instanciation of alot of classes actually...
i just want to make a POST request this shouldnt be so hard

InputScreen.java:302: cannot find symbol
symbol : variable Connector
location: class InputScreen
conn = (HttpURLConnection) Connector.open( check
URL );

[Norm]

Where is the class: Connector defined?

Locked (temporarily if need be) due to spam attack.

Edit: sorry for the re post but someone locked the other thread, probably because im new and they think im a spam bot, but nope im just a guy who wants to make a post request

No, nobody thought you were a spambot. But there were a series of spambot posts to your thread, so the thread was locked temporarily.

I've merged your new post here.

[chopficaro]

i dont know where the class connector is defined
thats what ive been trying to say
i just saw the code on the link i posted, but i cant find connector class on the oracle site, so i cant type in the import statement
why did they not show the instanciation or import in the guide i posted idk

[chopficaro]

i would show u my code but it is so messed up from dumb stuff ive done to try to fix it
can someone just explain the missing information to me?
why is it so hard to make a post request????

[Norm]

Perhaps you should start with a new version that doesn't copy code that's missing parts.

Try using the URL openConnection() method. Print out the value it returns.

[chopficaro]

ok i looked up url openConnection(), it said to make a post request do this

String urlParameters = "param1=a&param2=b&param3=c";
String request = "http://example.com/index.php";
URL url = new URL(request); 
HttpURLConnection connection = (HttpURLConnection) url.openConnection();           
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false); 
connection.setRequestMethod("POST"); 
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(urlParameters.getBytes().length));
connection.setUseCaches (false);

DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
connection.disconnect();

but the last few lines dont make any sense. how do i get the content returned by the post request as a string?

[Norm]

"it" said.
Who is the "it"?

Get the input stream and read from that.
