WebSocket returning 403 every time

问题

我不确定为什么会出现这个错误，但是当我尝试在浏览器中连接时，它失败并返回403错误。但这并没有道理，因为在我的代码中没有明确告诉它返回403，并且没有使用中间件。我附上了我得到的错误的图片。我还在使用Gorilla websocket和gin，以下是托管它的代码：

  1. func WebsocketServer(w http.ResponseWriter, r *http.Request, context *gin.Context) {
  2.     fmt.Println("connection received")
  3.     var upgrader2 = websocket.Upgrader{
  4.         CheckOrigin: func(r *http.Request) bool {
  5.             return true
  6.         },
  7.         EnableCompression: false,
  8.     }
  9.     db, err := aws.GetDB()
  10.     if err != nil {
  11.         helpers.Log.Println(err)
  12.         return
  13.     }
  14.     defer db.Close()
  15.     c, err := upgrader2.Upgrade(w, r, nil)
  16.     if err != nil {
  17.         helpers.Log.Println(err)
  18.         return
  19.     }
  20. }
  1. func PublicRoutes(c *gin.RouterGroup) {
  2.     c.GET("/ws", func(c *gin.Context) {
  3.         relay.WebsocketServer(c.Writer, c.Request, c)
  4.     })
  5. }

我正在使用AWS来托管这个，这是一个托管问题吗？

[GIN] 2023/05/07 - 22:18:49 | 403 | 18.344µs | 71.121.188.229 | GET "/ws"

I'm not sure why this error keeps occurring but when I try connecting in my web browser it fails and returns 403, but it doesn't make sense since no where in my code I specifically told it to return 403, and no middleware is involved, I attached a picture of the error im getting. Im also using Gorilla websocket with gin, here is my code that hosts it

  1. func WebsocketServer(w http.ResponseWriter, r *http.Request, context *gin.Context) {
  2.     fmt.Println("connection received")
  3.     var upgrader2 = websocket.Upgrader{
  4. 		CheckOrigin: func(r *http.Request) bool {
  5. 			return true
  6. 		},
  7. 		EnableCompression: false,
  8. 	}
  9. 	db, err := aws.GetDB()
  10. 	if err != nil {
  11. 		helpers.Log.Println(err)
  12. 		return
  13. 	}
  14. 	defer db.Close()
  15. 	c, err := upgrader2.Upgrade(w, r, nil)
  16. 	if err != nil {
  17. 		helpers.Log.Println(err)
  18. 		return
  19. 	}
  21. }
  1. func PublicRoutes(c *gin.RouterGroup) {
  2.     c.GET("/ws", func(c *gin.Context) {
  3.         relay.WebsocketServer(c.Writer, c.Request, c)
  4.     })
  5. }

Im using aws to host this, is it a hosting issue?

[GIN] 2023/05/07 - 22:18:49 | 403 | 18.344µs | 71.121.188.229 | GET "/ws"

这个问题不再是一个问题了，似乎是我的CORS出了问题？我通过将配置移到底部来解决了这个问题。我应该在初始问题中放置这段代码。

之前的代码：

  1. router := gin.Default()
  2. config2 := cors.DefaultConfig()
  3. config2.AllowOrigins = []string{"http://localhost:3000", "https://rblxfortune.vercel.app", "https://bloxbet.click", "http://localhost:80"}
  4. config2.AllowCredentials = true
  5. router.Use(cors.New(config2))
  7. HandleRoutes(router)
  8. public := router.Group("/")
  9. routes.PublicRoutes(public)
  10. router.NoRoute(func(c *gin.Context) {
  11.     http.Redirect(c.Writer, c.Request, "/login", http.StatusMovedPermanently)
  12. })
  13. private := router.Group("/")
  14. private.Use(helpers.AuthRequired)
  15. routes.PrivateRoutes(private)
  17. err := router.Run(config.Port)
  18. if err != nil {
  19.     log.Println(err)
  20. }

修改后的代码：

  1. router := gin.Default()
  3. HandleRoutes(router)
  4. public := router.Group("/")
  5. routes.PublicRoutes(public)
  6. router.NoRoute(func(c *gin.Context) {
  7.     http.Redirect(c.Writer, c.Request, "/login", http.StatusMovedPermanently)
  8. })
  9. private := router.Group("/")
  10. private.Use(helpers.AuthRequired)
  11. routes.PrivateRoutes(private)
  12. config2 := cors.DefaultConfig()
  13. config2.AllowOrigins = []string{"http://localhost:3000", "https://rblxfortune.vercel.app", "https://bloxbet.click", "http://localhost:80"}
  14. config2.AllowCredentials = true
  15. router.Use(cors.New(config2))
  16. err := router.Run(config.Port)
  17. if err != nil {
  18.     log.Println(err)
  19. }

This issue is no longer a problem, it seemed to be an issue with my CORS? I fixed it by moving the configuration to the bottom. I should've put this code in my intial question

Before

  1. router := gin.Default()
  2. config2 := cors.DefaultConfig()
  3. 	config2.AllowOrigins = []string{"http://localhost:3000", "https://rblxfortune.vercel.app", "https://bloxbet.click", "http://localhost:80"}
  4. 	config2.AllowCredentials = true
  5. 	router.Use(cors.New(config2))
  7. 	HandleRoutes(router)
  8. 	public := router.Group("/")
  9. 	routes.PublicRoutes(public)
  10. 	router.NoRoute(func(c *gin.Context) {
  11. 		http.Redirect(c.Writer, c.Request, "/login", http.StatusMovedPermanently)
  12. 	})
  13. 	private := router.Group("/")
  14. 	private.Use(helpers.AuthRequired)
  15. 	routes.PrivateRoutes(private)
  16. 	
  17. 	err := router.Run(config.Port)
  18. 	if err != nil {
  19. 		log.Println(err)
  20. 	}

After

  1. router := gin.Default()
  3. 	HandleRoutes(router)
  4. 	public := router.Group("/")
  5. 	routes.PublicRoutes(public)
  6. 	router.NoRoute(func(c *gin.Context) {
  7. 		http.Redirect(c.Writer, c.Request, "/login", http.StatusMovedPermanently)
  8. 	})
  9. 	private := router.Group("/")
  10. 	private.Use(helpers.AuthRequired)
  11. 	routes.PrivateRoutes(private)
  12. 	config2 := cors.DefaultConfig()
  13. 	config2.AllowOrigins = []string{"http://localhost:3000", "https://rblxfortune.vercel.app", "https://bloxbet.click", "http://localhost:80"}
  14. 	config2.AllowCredentials = true
  15. 	router.Use(cors.New(config2))
  16. 	err := router.Run(config.Port)
  17. 	if err != nil {
  18. 		log.Println(err)
  19. 	}
  21. </details>
