设置杜松子酒中找不到的路线 [英] Setting up Route Not Found in Gin

问题描述

我已经在Gin中设置了默认路由器和一些路由:

I've setup a default router and some routes in Gin:

router := gin.Default()
router.POST("/users", save)
router.GET("/users",getAll)

但是我该如何处理杜松子酒中找不到404路线?

but how do I handle 404 Route Not Found in Gin?

最初，我使用的是了解Gin所用的httprouter，所以这就是我本来拥有的...

Originally, I was using httprouter which I understand Gin uses so this was what I originally had...

router.NotFound = http.HandlerFunc(customNotFound)

和功能:

func customNotFound(w http.ResponseWriter, r *http.Request) {
    //return JSON
    return
}

但这不适用于Gin.

我需要能够使用 c * gin.Context 返回JSON，以便可以使用:

I need to be able to return JSON using the c *gin.Context so that I can use:

c.JSON(404, gin.H{"code": "PAGE_NOT_FOUND", "message": "Page not found"})

推荐答案

您正在寻找的是

What you're looking for is the NoRoute handler.

更准确地说:

r := gin.Default()

r.NoRoute(func(c *gin.Context) {
    c.JSON(404, gin.H{"code": "PAGE_NOT_FOUND", "message": "Page not found"})
})
