Microbusement applet and public number to implement data interworking

company because of the small program project first on the line, after the public No. develop, received a superior arrangement to achieve a small program to get through the task, look after the document was found: the same developer account as long as the binding applet with the public number WeChat open platform for the future there will be a unique unionid, this product share at unionid Tencent. This is the key unionid we get through. After

1 micro-channel public number applet after binding, the applet calls wx.login () method:

Let me talk about ideas. will automatically get unionid, according to the official number of public documents after obtaining information about users will get the same unionid, openid, nickname. . . . Other relevant information;

2 unionid applets get information updating operation, get the number of public databases unionid the like, stores the new database table A; (NOTE: In this step, since we the company reasons, before our public No. someone concern, then before that, I get concerned about the user through the public number list to get a list openid were cycled openid list, the call to the public number to obtain information about users list stored in a database table a event, before the end of the cycle concerned person information is stored in the database a, is then performed, this step of operation)

3. number of public interest by load / off corresponding to the database table a deletions operation, maintain freshness transactions;.

4 relational query, this step we find that, after association table by unionid we have achieved interworking of the

eloquent He said a lot, in fact, the two interfaces is critical number of public (1 concern / take off events corresponding user interfaces 2. get the basic information Interface)

about public security number domain configuration, the domain name server configuration and access token is not here to say, Baidu, a lot.

Code Implementation:

The first step Gets a list of the public number of the user operation openid, According to the query of the basic information of the user, deposit the database operation (because our company’s public number is only 1000+, so I only call the interface to get the list of attention)
