node.js - 将 session 写入 MongoDB 时出错

Question

我正在开发一个 Node 应用程序并使用 MongoDB 来存储 session 。该应用程序使用 Linkedin oAuth 和 MongoDB。

我的代码:

var store = new MongoDBStore({
    uri: mongoUri,
    collection: '_sessions',
    function(err) {
        console.log(err);
    }
});

// Catch MONGO CONNECTION errors
store.on('error', function(error) {
    assert.ifError(error);
    assert.ok(false);
});

// if (isLocal) {
//     app.use(session({resave: 'true', saveUninitialized: 'true', secret: 'keyboardcat'}));
// }else{
// }
app.use(session({
    store: store,
    resave: 'true',
    saveUninitialized: 'true',
    secret: process.env.SESSION_SECRET,
    cookie: {
        maxAge: 1000 * 60 * 60 * 24 * 7
    }
}));

应用启动时出现以下错误。

Error: Error setting ZwkuhpnbkYgD1HzscBJ8w2fmhwZpiQPL to Session {
  cookie: 
   { path: '/',
     _expires: 2016-09-20T22:20:15.753Z,
     originalMaxAge: 604800000,
     httpOnly: true,
     secure: null,
     domain: null },
  passport: {},
  'oauth2:www.linkedin.com': { state: 'DqyHf7eqG8RCN7BYRkG9NSUV' } }: The dotted field 'oauth2:www.linkedin.com' in 'session.oauth2:www.linkedin.com' is not valid for storage.

我知道 mongodb 提示虚线字段。我的问题是，在用户经过身份验证之后，如何在将其写入 Passport 之前拦截 session :{}？

您可以在定义 LinkedIn 策略时将其添加为选项来覆盖所使用的“sessionKey”

passport.use(new LinkedinStrategy({ ...options, sessionKey: 'linkedin'},Strategy.linkedin));
