我封装到js里面的，直接调用就行了
授权登录：

// 用户登录
export function userLogin() {return new Promise((resolve, reject) => {var loginData = {}uni.login({success(res) {if (res.code) {//发起网络请求loginData.code = res.code// 获取微信用户信息}}})uni.getUserProfile({desc: '用于完善资料',success: function(res) {// console.log('getUserInfo', res)loginData.signature = res.signatureloginData.rawData = res.rawDataloginData.encryptedData = res.encryptedDataloginData.iv = res.ivuni.setStorageSync('loginInfo', res)login(loginData).then((res) => {     //后端登录接口// console.log('微信登录',res)uni.setStorageSync('sessionKey', res.data.sessionKey)setToken(res.data.token)getInfo().then((respose) => {      //后端获取用户信息接口resolve(respose)uni.$emit('loginUser','登陆了')})})},fail: res => { // 获取失败的去引导用户授权console.log(res)}})})
}

先访问uni.login得到code存起来，再访问uni.getUserProfile获取rawData、iv等数据，再加上code一起返回给后端，再请求后端接口
手机号授权：

// 用户授权手机号
export function userPhone(e) {return new Promise((resolve, reject) => {var phone = {}var res = e.detail// console.log('事件源', e.detail)if (res.errMsg == "getPhoneNumber:ok") {phone.sessionKey = uni.getStorageSync('sessionKey');phone.signature = uni.getStorageSync('loginInfo').signature;phone.rawData = uni.getStorageSync('loginInfo').rawData;phone.encryptedData = res.encryptedDataphone.iv = res.iv}})
}

页面中：

<button class="phone-button" open-type="getPhoneNumber" @getphonenumber="$noMulClicks(getPhoneNumber)">未绑定手机号</button>getPhoneNumber(e) {userPhone(e).then((res) => {if (res === 200) {//成功后的操作}})
},
