Java simulated HTTP GET POST request easily realize campus BBS automatic reply _java

The example of this article for everyone to share the Java simulation HTTP GET POST request, Campus BBS automatic reply function, for your reference, the specific contents are as follows

Design ideas

Find the collection of post links, the last number of changes, you can get different posts

Prevent the post will be deleted again, to determine whether the post exists

To traverse this collection, post requests for replies to each link

Key points

Note:

• Replies require user Login information
• One is the use of cookies
• The other is to simulate a login
• This paper uses the former

Code

The code is relatively simple, the note is to find their own cookies, assigned to string Yourcookeie can be run directly

The main thing is to judge the existence of a post, this is a GET request, and then send a reply with post, the reply information in mapdata.put ("message", "Friendship help Top") in the hard code for "friendship Help Top", you can modify
