java调⽤js-sdk接⼝
JSSDK使⽤步骤
步骤⼀：绑定域名
注意：前⾯不需要加http
步骤⼆：引⼊JS⽂件
jquery.js⾃⾏下载到⾃⼰的⼯程引⼊即可。
<script src="/js/jquery.js"></script>
<script src="res.wx.qq/open/js/jweixin-1.0.0.js"></script>
前端传的 url : https%3A%2F%2Foftoo.site%2F%3Fcode%3D071N3ldz0A3Ixd1RIXez0fqXcz0N3ldT%2
6state%3D123 在后的代码要decode

根据JSAPITICKET⽣成的字符串。与返回的数据在签名校验⼯具⽹址进⾏对⽐加密后的signature是否⼀致
