The mobile phone browser calls out the QQ chat window, and the WeChat built-in browser calls out the QQ

Method 1: This method can also call out qq in the WeChat built-in browser.

http://shang.qq.com/v3/index.h tml

1. Log in to QQ

2. Enter the "Promotion Tool", if it is a newly registered QQ account, the first time you log in, you will be prompted to "Open now for free"

3. Copy the code and modify it to your own QQ number
http://wpa.qq.com/msgrd?v=3&uin= Enter QQ number here&site=qq&menu=yes

4. Test
Copy and paste the generated link into the browser, click Enter, and the following prompt will pop up. If you have multiple QQ accounts logged in on your computer

Note: If it is a newly registered QQ account, if you have not logged in on QQ promotion and activated this service, just copy the above link and modify it into a QQ account. This function cannot be realized. When you open the link, the webpage will automatically flash and close. .

Solution:
For a new QQ account, you need to log in to QQ promotion, click "Open now for free", and then continue with the above operations.

Method 2: This has not been tried in WeChat

< a   href = "mqqwpa://im/chat?chat_type=wpa&uin=your QQ number&version=1&src_type=web" > Contact me </ a >

Sometimes it is not enough to just have a link to jump. Maybe our webpage needs to know whether QQ is online in time, and there is also an interface:

< script >  var  online= new  Array();  </ script >
< script  src = "http://webpresence.qq.com/getonline?Type=1&QQ号1:QQ号2:" > < script > ;
