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。
5、代码块(个人喜好把SDK放在extend里面)
