uni-app微信小程序新版getUserProfile使用

1、小程序封装

getUserProfile 获取用户信息。页面产生点击事件（例如 button 上 bindtap 的回调中）后才可调用，每次请求都会弹出授权窗口，用户同意后返回 userInfo。该接口用于替换 wx.getUserInfo，详见 用户信息接口调整说明

async weixinlogin () {
        let wxLoginRt={code:''}
        // 获取code
        Promisify('login').then(res=>{
            wxLoginRt.code=res.code
        }).catch((err) => {
        })

        const wxUserInfo = await Promisify('getUserProfile', { lang: 'zh_CN',desc:'登录' }).catch((err) => {
          throw Error('获取用户信息失败')
        })
        console.log(wxUserInfo)
        const { code: lp_code } = wxLoginRt
        wxUserInfo.rawData = JSON.parse(wxUserInfo.rawData)
        loginByWxLp({
                code: lp_code,
                encryptedData:wxUserInfo.encryptedData,
                iv:wxUserInfo.iv,
                rawData: JSON.stringify(wxUserInfo.rawData),
                signature:wxUserInfo.signature,
        }).then(res=>{
                if(res.code == 1){
                     console.log('登录成功');
                }
        }).catch(e=>{
                console.error(e);
        })
    }
  },

2、后台接口

使用easywachat

  public function loginByWxLp()
    {
        $post = $this->request->post();
        $code = $post['code'];
        $encryptedData = $post['encryptedData'];
        $rawData = $post['rawData'];
        $signature = $post['signature'];
        $iv = $post['iv'];

        if (empty($code) || empty($encryptedData) || empty($iv) || empty($rawData)) {
            $this->error('missing params');
        }

        $app = Factory::miniProgram(config('wechat'));

        $open_res  = $app->auth->session($code);
        if (empty($open_res['session_key'])) {
            Log::write('wxLoginFail:' . json_encode($open_res, JSON_UNESCAPED_UNICODE), 'notice');
            $this->apiError('code2session fail');
        }

        try {
            $wx_info = $app->encryptor->decryptData($open_res['session_key'], $iv, $encryptedData);
            $wx_info = array_merge($open_res, $wx_info);
            Log::write('wxLoginSucess:' . json_encode($wx_info, JSON_UNESCAPED_UNICODE), 'notice');
        } catch (\Throwable $e) {
            Log::write('wxLoginFail:' . $e->getMessage(), 'notice');
        }
        $user = User::where('open_id', $open_res['openid'])->find();
        if($user){
            //用户已存在，则返回用户信息
        }else{
            //用户不存在，则新增用户
        }
    }
