Campus Network Automatic Login Program

Recently took advantage of the campus network for free in the paper, but face black, the old school network kicked, love.

Then wrote a escort of automatic login ~

STEP1: Analysis Package

Before I naively thought that just write the user name and password on the line = Ah I want to find time to repair computer network.

In the browser installed Firebug plug-in, manually login and grabbed the package.

Analysis:

1. Under the network options, see the address is sent, the mouse can see the specific address, the bad is not cut.

2. Expand it, you can see a bunch of things in the request header, it's just about the host and Referer.

3. In the post bar, see the specific sent parameters

Then the basic information is ready.

STEP2: Detecting If there is an Internet connection

Open a Web page to see if it can be opened, because the open Web page is not logged in will be directed to the login page (also may not open), so first detect whether it can be opened, if so, the analysis page element detection title is consistent.

Here Microsoft Dafa works with Bing as a test page =w=

STEP3: Build your own packets and send

It is good to use Python Dafa here.
