微信支付出现的问题总结--不同域名进行授权解决方案

时间：2015-07-20 12:47:32   收藏：0   阅读：373
    1、如果使用的是微信支付的方式，并且使用的是native的支付方式，那么需要在服务器上生成一张二维码，注意二维码的路径问题：
  1. String imgName  = UUID.randomUUID().toString().replace("-", "") +".png";
  2. String QRPath =  this.getServletContext().getRealPath("/pay/QRIMG/wx") + imgName;
    使用上述的方式可以解决路径问题；在项目中直接引用该文件就可以了
   2、在多个项目中，由于微信的授权登陆只能配置一个，如下图（不同域名进行授权解决方案）：

此时我们想获得到微信授权到不同的域名，此时的方法为：

这里贴出2个主要的授权方法：

3、微信openid的区别：
    在开发微信的时候，如果你使用了测试账户，测试账户值得是：在公众平台设置的测试账号；测试你用过授权得到的openid，和实际使用的openid是不一致的！，需要特别的注意，在正式上线的时候，需要使用真实的openid；
    使用测试账号的openid和测试的首选域，是可以完成支付测试的，需要注意：只技术分享
公众平台设置了测试授权目录才能进行相应的支付测试，负责，不能完成支付；
