Basic Usage

The following gateways are provided by this package:

• WeChat Express (WeChat JSAPI)

For general usage instructions, please see the main Omnipay repository.

WeChat JSAPI require OAuth openid to submit a new order, use$WeChat_Express->getAuthCode($callback)to get an url for WeChat OAuth and$WeChat_Express-->getOpenid($code)in callback page to get openid.

p.s. the url for WeChat OAuth must be opened in WeChat In-App broswer, you can usestrpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') === falseto check if the page were not opened in it, and generate a QR code for user.

All methods for WeChat OAuth will be removed in next stable version and I'll publish a WeChat MP library package for composer.
