微信小程序获取开发之获取openId和手机号码
微信官网：https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/getPhoneNumber.html
1、获取code 直接调用API获取code即可，然后将code作为参数传递给接口。
代码语言：javascript复制<button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber"></button> Page({
getPhoneNumber (e) {
console.log(e.detail.code)
}
})此处code就是动态口令，有效期5min。
2、获取openID和手机号码的util类
