会话不会保存在会话variables中。 导航后，req.user不存在

背景：

我有一个运行在端口4200上的angular度cli，以及运行在3000上的服务器端api node.js。

我发现会话护照值不会保存后，与本地护照login。

所以当我尝试导航到另一个页面login后，其不持有护照，会话中的variables，因为它应该是，需要调用req.user

出于某种原因，服务器不调用反序列化用户。

请求login后redirect到页面/testing。

更新：

login我使用端口4200发送一个请求，使用以下代码：（angular2 / 4）

 performLogin(name: string, password: string): Observable<Comment[]> { var params = new URLSearchParams(); params.append('username', name); params.append('password', password); url = "SITE:3000/api/login"; return this.http.post(this.url,params, this.options) .map(result => result.json()) .do(result => this.result = result); } 

更新2：插入信用请求客户端双面。 在每一个请求login – >然后调用testing页我总是得到：

 ReferenceError: User is not defined at /root/mafiagame/src/config/passport.js:32:9 at pass (/usr/lib/node_modules/passport/lib/authenticator.js:347:9) at Authenticator.deserializeUser (/usr/lib/node_modules/passport/lib/authenticator.js:352:5) at SessionStrategy.authenticate (/usr/lib/node_modules/passport/lib/strategies/session.js:53:28) at attempt (/usr/lib/node_modules/passport/lib/middleware/authenticate.js:348:16) at authenticate (/usr/lib/node_modules/passport/lib/middleware/authenticate.js:349:7) at Layer.handle [as handle_request] (/root/mafiagame/node_modules/express/lib/router/layer.js:95:5) at trim_prefix (/root/mafiagame/node_modules/express/lib/router/index.js:317:13) at /root/mafiagame/node_modules/express/lib/router/index.js:284:7 at Function.process_params (/root/mafiagame/node_modules/express/lib/router/index.js:335:12) at next (/root/mafiagame/node_modules/express/lib/router/index.js:275:10) at initialize (/usr/lib/node_modules/passport/lib/middleware/initialize.js:53:5) at Layer.handle [as handle_request] (/root/mafiagame/node_modules/express/lib/router/layer.js:95:5) at trim_prefix (/root/mafiagame/node_modules/express/lib/router/index.js:317:13) at /root/mafiagame/node_modules/express/lib/router/index.js:284:7 at Function.process_params (/root/mafiagame/node_modules/express/lib/router/index.js:335:12) 

相关的问题，这并没有解决我的问题：

Passportjslogin后不保存用户进入会话

PassportJS反序列化用户从未调用过

快速护照会议不起作用

req.session.passport为空，反序列化用户未调用 – ExpressJS，护照

主要问题：请求login后redirect到页面/testing。

看起来会话被保存了，但是会话中的护照详情不是。

我的应用程序：

login后req.session转储：

  Session { cookie: { path: '/', _expires: 2017-05-03T19:42:58.728Z, originalMaxAge: 14400000, httpOnly: true, secure: false }, passport: { user: '5909a6c0c5a41d13340ecf94' } } 

会话时访问/testing

 Session { cookie: { path: '/', _expires: 2017-05-03T19:43:10.503Z, originalMaxAge: 14400000, httpOnly: true, secure: false } } 

server.js

这里是我的server.js与快递，护照等

用户variables包含：

来自访问/testing的服务器响应

这似乎是一个angular度2/4的问题。 你可以尝试这个或这个

希望它能帮助你！ 🙂
