1.获取京东小程序appid
2.通过京东给的文档接口得到推广链接
3.跳转
url路径：pages/union/proxy/proxy?spreadUrl={encoded获取到的推广链接}&EA_PTAG=17078.27.178 调用微信小程序wx.navigateToMiniProgram(Object object)接口实现跳转 跳转方式参考微信小程序官网文档 示例：
let e = encodeURIComponent('转链后的链接');wx.navigateToMiniProgram({appId: 'xxxxxxxxxxxxx',path: 'pages/union/proxy/proxy?spreadUrl=' + e+ '&EA_PTAG=17078.27.178',envVersion: 'release',success(res) {console.log(res)},fail(res) {//拒绝之后返回上一页if (refuse == 0) {wx.navigateBack({delta: 1,})} else {console.log(res)wx.switchTab({url: '/pages/index/index',})}}});
5.跳转后的界面，如图：
