已解决，不知道靠不靠谱贴上代码。 button 组件授权后在调用wx.login 进行解密 userInfoHandler: function (e) { let that = this; if (e.detail.errMsg =='getUserInfo:ok') { wx.login({ success: function (r) { let code = r.code; if (code) { // 解密用户数据 wx.request({ url: url, method: 'post', header: {'content-type': 'application/x-www-form-urlencoded'}, data: {encryptedData: e.detail.encryptedData, iv: e.detail.iv, code: code}, success: function (data) { console.log(data); if (data.data.status == 1) { app.globalData.userInfo = data.data.userInfo; wx.setStorageSync('userInfo', data.data.userInfo); // 缓存用户信息 typeof cb == "function" && cb(app.globalData.userInfo); app.navigateBack('navigateTo', '/pages/index/index'); } else { // 失败 that.showMsg(data.data.msg); } }, fail: function (err) { that.showMsg(err.errMsg); console.log(err) } }) } else { that.showMsg(err.errMsg); console.log('获取用户登录态失败！', err) } }, fail: function (err) { that.showMsg(err.errMsg); console.log('登陆失败', err); } }) } }
