公众号直接唤起微信支付
1、支付授权目录说明：
1-1、商户最后请求拉起微信支付收银台的页面地址我们称之为“支付目录”，例如：https://www.weixin.com/pay.php。
1-2、商户实际的支付目录必须和在微信支付商户平台设置的一致，否则会报错“当前页面的URL未注册：”
2、登录微信支付商户平台（pay.weixin.qq.com）–>产品中心–>开发配置，设置后一般5分钟内生效。
3、支付授权目录校验规则说明：
3-1、如果支付授权目录设置为顶级域名（例如：https://www.weixin.com/ ），那么只校验顶级域名，不校验后缀；
3-2、如果支付授权目录设置为多级目录，就会进行全匹配，例如设置支付授权目录为https://www.weixin.com/abc/123/，则实际请求页面目录不能为https://www.weixin.com/abc/，也不能为https://www.weixin.com/abc/123/pay/，必须为https://www.weixin.com/abc/123/
4、网页授权域名
开发JSAPI支付时，在统一下单接口中要求必传用户openid，而获取openid则需要您在公众平台设置获取openid的域名，只有被设置过的域名才是一个有效的获取openid的域名，否则将获取失败。在公众号设置—功能设置—网页授权域名设置。注意证书的下载和位置。
