(Web、触屏)微信支付功能调用以及QQ回调地址配置、以及遇到的一些坑

2.微信拦截，获取微信登录的openid

此处测试经常遇到的问题总结如下：

1.需要配置域名测试，必须是http://www.baidu.com这样的类似的域名，必须是www开头

2.唤起微信支付页面二级链接必须要在微信官网上有注册，是二级目录的 http://www.2bulu.com/

http://www.2bulu.com/lolapay/webchat_travel_pay.htm //这样子就可以了、二级目录：lolapay，换成别的就不可以
就会出现图三错误：url未注册

3.本地测试的时候必须是正规的域名，后面不能加后缀如 http://www.xxx.com/tbl/....这个tbl不能要的

必须是这个样子：http://www.2bulu.com/community/gotohuatinfo.htm?id=40467&type=1

/*//微信调用成功会出现如下的链接如下：
https://open.weixin.qq.com/connect/oauth2/authorize?
    appid=wxf4089e0e20e0c44b&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Ftbl%2Fcommunity%2Fcommon%2F
authorization_open_id.htm%3Fa%3Db&response_type=code&scope=snsapi_base&state=authorize_flag
&uin=NDE1MzkwMjQw&key=2d22aaf0f212624a6154ffe6be5f7790d1b68cf1bade9a5203542e07012e86f01da8d387a1669b38da63b1495bc32148&
pass_ticket=dfUpz5Or1CLGRwxk2rJYbR5+3diWDT4Ik8wcvTYorY5/K5hYIcbKAsGZOx4uVFlLNLcm/EqrFlRrqZ0a00Q7nA==
*/


/*这个是接口返回的js用来唤起
**/

4.本地测试话，需要改下host文件：映射为域名

配置回调地址、地址必须是域名http开头，加上正确的地址

手机端用微信支付经常会遇到一个问题就是回调地址，提前回调了，通过查看微信支付的API上面说

所以必须要重定向到一个中间页面来唤起微信，到时候微信支付完成或取消支付都会，再回到这个中间页面，中间页面可以让用户自己做处理或者用轮询去查数据库订单状态，上图请确认微信需要放到一个中间页面 ，下图就是我自己随便做的一个跳转页面
