Node.js 多次调用PassportJS中间件_Node.js_Express_Passport.js_Sequelize.js

Node.js 多次调用PassportJS中间件

node.js express sequelize.js

Node.js 多次调用PassportJS中间件,node.js,express,passport.js,sequelize.js,Node.js,Express,Passport.js,Sequelize.js,似乎每当我调用Passport的ensureAuthenticated中间件时，就会导致Passport.deserializeUser函数被额外调用6-7次。我不确定这是我的应用程序通过Express、Sequelize的结构还是Passport的导入方式。出于这个原因，我将列出一些文件，希望找到它误入歧途的地方以下是我如何组织一切的 application/ auth/ models/ node-modules/ public/ routes/ views/ a

似乎每当我调用Passport的

ensureAuthenticated

中间件时，就会导致

Passport.deserializeUser

函数被额外调用6-7次。我不确定这是我的应用程序通过Express、Sequelize的结构还是Passport的导入方式。出于这个原因，我将列出一些文件，希望找到它误入歧途的地方

以下是我如何组织一切的

application/
  auth/
  models/
  node-modules/
  public/
  routes/
  views/
  app.js

我的假设是，要么是因为中间件不是单例，要么是因为我的路由设置很奇怪注意：我遵循了关于设置单例续集方法的指南

我知道这是一段代码，但我感觉它非常简单。任何指导都将不胜感激。

我刚刚遇到了这个问题。所有静态资产都通过中间件运行的原因是，您要么没有定义什么是静态资产，要么定义得太晚。我必须告诉它使用

/assets

作为公共文件的基础，然后你必须确保它先于你的其他应用。使用定义

app.use（'/assets'，express.static（path.join（'public'））
这是因为您使用的passportJS会话中间件早于静态文件。因此，您的所有静态文件调用（如
）都将通过会话中间件并调用反序列化user（）

解决方案
在app.js文件中使用（express.static（…）
之后使用会话中间件

您使用的编辑器/IDE是什么？我强烈推荐使用Jetbrains Webstorm。然后，只需添加几个断点并检查调用堆栈即可快速回答问题。或者，也可以调用console.trace（）
fromdeserializeUser
。/auth/index.js
中deserializeUser
的日志/跟踪会随着SQL执行而重复-这似乎是多次调用的内容。另外，只需vim/zsh即可。确保您的公用文件夹不是通过express调用的，而是通过它前面的东西（apache、nginx等等）调用的。因为每次CSS/JS/img/etc.调用都会触发中间件（发生在我身上）。@user766987我刚刚遇到了这个问题。所有静态资产都通过中间件运行的原因是，您要么没有定义什么是静态资产，要么定义得太晚。我必须告诉它使用/assets
