在我們平時工作、學習、生活中,微信小程序已成為我們密不可分的一部分,我們仔細留意下,每當我們使用一個新的小程序時,總會遇到如下頁面:
這便是微信小程序授權(quán)登錄功能了,授權(quán)登錄后,我們就可以正常使用小程序,而小程序也會獲取到我們的用戶權(quán)益,手機號等個人信息
授權(quán)登錄功能剖析
微信小程序的授權(quán)登錄具體步驟如下所示
具體實現(xiàn)主要有以下三個步驟:
調(diào)用wx.login() 微信api獲取臨時登錄憑證code,并回傳到開發(fā)者服務(wù)器
調(diào)用auth.code2Session?微信api接口,獲取用戶唯一標識OpenID、 用戶在微信開放平臺帳號下的唯一標識UnionID和會話密鑰session_key
通過步驟2獲取的參數(shù)進行解密操作,獲取用戶手機號,頭像等特性,并把需要的數(shù)據(jù)保存到緩存中
步驟實現(xiàn)代碼如下:
一、獲取臨時登錄憑證code
由于微信官方修改了getUserInfo接口,現(xiàn)在無法實現(xiàn)一進入微信小程序就會自動彈出授權(quán)窗口,所以我們只能通過button按鈕讓用戶手動觸發(fā)
我們先寫一個簡單的彈框,用isShow變量控制,isShow取決于步驟3中的緩存信息,當所有步驟都走通,會正確緩存用戶信息,此時彈框隱藏,否則彈框都為顯示狀態(tài)
??<view> ????????<view> ??????????<text>需要先授權(quán)獲取個人信息</text> ??????????<button>微信賬號快速授權(quán)</button> ????????</view> ??</view>
點擊按鈕時,調(diào)用getUserInfo方法,isShow設(shè)置為false,同時使用wx.login獲取到登錄憑證code
getUserInfo:e=>{??????this.setData({????????isShow:false ??????}) ??????wx.login({????????success:?function?(res)?{???????????????let?code?=?res.code?//?登錄憑證code ?????????} ??????}) ?????? ??}
二、根據(jù)登錄憑證code,獲取用戶登錄信息
拿到登錄憑證code后,調(diào)用auth.code2Session?微信api接口(此處為服務(wù)端操作,后端大佬搞定,我們直接調(diào)用他給的接口就好)
?????????wx.request({????????????????url:?獲取用戶信息的auth.code2Session微信api接口,????????????????method:?'POST',????????????????data:{??????????????????code:code//登錄憑證code ????????????????},????????????????header:?{??????????????????'content-type':?'application/json;charset=UTF-8' ????????????????},???????????????? ????????????????success:?function?(res)?{??????????????????var?userphone=?res.data.data??????????????????//解密手機號 ??????????????????var?msg?=?e.detail.errMsg;??????????????????var?sessionKey?=?userphone.session_key;//會話密鑰 ??????????????????var?encryptedData=e.detail.encryptedData;?//簽名 ??????????????????var?unionid?=?userphone.unionid//唯一標識 ??????????????????var?iv=?e.detail.iv;??????????????????//授權(quán)成功 ??????????????????if?(msg?==?'getPhoneNumber:ok')?{ ????????????????????wx.checkSession({??????????????????????success:function(){????????????????????????//進行請求服務(wù)端解密手機號 ????????????????????????this.deciyption(sessionKey,encryptedData,iv,unionid); ??????????????????????} ????????????????????}) ??????????????????} ????????????????} ??????????????}) ????????} ??????})
此時大多數(shù)用戶信息我們已經(jīng)獲取了,但用戶手機號,用戶頭像等信息還處于加密狀態(tài),我們需要去解密獲取這些參數(shù)
三、根據(jù)用戶信息,解密獲取用戶手機號
deciyption(sessionKey,encryptedData,iv,unionid){????var?that?=?this; ????wx.request({??????url:?解密接口,??????method:?'POST',??????data:?{????????sessionKey:?sessionKey,????????encryptedData:encryptedData,????????iv:?iv ??????},??????header:?{????????'content-type':?'application/json;charset=UTF-8' ??????},??????success:?function(res)?{ ????????let?data?=?res.data????????if?(data.resultCode?==?'success')?{ ????????????wx.setStorageSync('userTel',?data.data.phoneNumber);//存儲解密后的用戶手機號 ????????}else{ ????????????wx.showToast({????????????????title:?'獲取信息失敗請重新授權(quán)',????????????????icon:?'none' ????????????}) ????????????that.setData({????????????????isShow:true ????????????}) ????????}???? ??????}, ??????fail:function(res)?{ ????????wx.showToast({????????????title:?'獲取失敗請重新授權(quán)',????????????icon:?'none' ????????}) ????????that.setData({??????????isShow:true ????????}) ??????} ????}) ??},
此時授權(quán)登錄功能已完成
