微信支付- 客户端提示签名错误！
但是后台的数据，在签名工具里检验是正确的。
1前端代码第一步用户 点击获取 code 传去去后台得openid
//getQueryString方法获取url参数的值 并且提取 code值
function getQueryString(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if(r != null) return unescape(r[2]);
return null;
}
var code = getQueryString("code");
//获取openid
$.ajax({
type: 'GET',
url: "",
dataType: 'json',
data: {
code: code
},
success: function(data) {},
error: function(error) {
alert("error");
}
});
