    app.get("/auth/loginByWeixin",
        passport.authenticate('loginByWeixin',{ successRedirect: '/test/hello',
            failureRedirect: '/login' })
    );

    //在微信客户端登录，使用/auth/loginByWeixinClient
    app.get("/auth/loginByWeixinClient",
        passport.authenticate('loginByWeixinClient',{ successRedirect: '/test/hello',
            failureRedirect: '/login' })
    );
```

### Weapp 微信小程序

#### 配置
test/bootstrap/providers.json
```json
...
    "clientID": "替换为自己的小程序AppID",
    "clientSecret": "替换为自己的小程序AppSecret",
...
```

#### 启动测试服务
```bash
# npm install
# npm start
```

#### HTTPS
由于小程序只支持HTTPS，需要将weapp passport server放在某HTTPS的反向代理后面才可以。类似下面2种途径
- `brew install nginx` and config ...
- `docker run -v ${PWD}/nginx/conf.d:/etc/nginx/conf.d -v ${PWD}/nginx/certs:/etc/nginx/certs -d -p 443:443 nginx`
