1、同步请求授权
作者:xiaochun365
需求分析:
1.在小程序首次打开的时候,我需要同时请求获取多个权限,由用户逐一授权。
([‘scope.userInfo’,‘scope.userLocation’,‘scope.address’,‘scope.record’,‘scope.writePhotosAlbum’])
问题分析:
1. wx.authorize接口同时调用,请求多个权限,由于异步原因,将授权请求一并发出,显然不符合要求。
2. promise能很好的解决问题,试着尝试了一下,下面代码分为两个文件。
import es6 from '../helpers/es6-promise'
function getScope(scopeName) {
return new es6.Promise(function (resolve, reject) {
wx.getSetting({
success(res) {
if (!res.authSetting[scopeName]) {
wx.authorize({
scope: scopeName,
success() {
resolve(0)
}, fail() {
resolve(1)
}
})
}
}
})
})
}
module.exports = { getScope: getScope }

import scope from "../../service/scope"

分析求解: 1.代码中问题1写法过于笨,但是尝试通过循环方式调用写法,又不知道如何处理回调问题。 2.wx.authorize接口,success参数官方给出的解释是(接口调用成功的回调函数),其实不然,实际上是接口调用成功,并且获取到了scope指定的权限.
2、用户拒绝授权,重新调起授权
