生成ticket值：{"success":true,"errorCode":1000000,"errorMsg":null,"result":{"debugTrace":http://www.wxticket.com/,"url":"weixin://dl/business/?ticket=tdfd2ba5686833d7ecdee6e11c86f7f64"}}<p>拼多多微信跳转api效果：<a href="weixin://dl/business/?ticket=tdfd2ba5686833d7ecdee6e11c86f7f64">手机浏览器打开测试<a/>

生成wxticket值即可用js调用跳转。
