如何在路线处理程序中定义护照策略？

Question

我有一个多租户应用程序，每个租户可以有不同的策略。我想在中间件或路由处理程序中设置通行证策略。

这是我想做的示例代码：

function loadTenantProviderSettings(req){
  // return settings
}

function generateProviderStrategy(provider, settings){
 // return strategy instance. ex:
 // new GoogleStrategy({ ...settings },
 //           (accessToken, refreshToken, profile, done) => {
 //             return done(null , profile);
 //           },
 //         ))
}


app.get('/socialLogin/:provider', function(req,res,next){
  const socialProvider = req.params.provider
  const settings = loadTenantProviderSettings(req);

  // Following works but I don't find it right. Because passport is singleton
  // passport.use( generateProviderStrategy(socialProvider, settings ) )
  // passport.authenticate(socialProvider, async (err, user, info ) => { })(req,res,next)

  passport.authenticate(socialProvider, settings, async (err, user,info) => { })(req,res,next)
})

预先感谢
