How to check for user agent for all requests?
问题
我有一个定义用户代理的函数：
func getUserAgent(c *gin.Context) bool {
ua := ua.Parse(c.Request.UserAgent())
if ua.Bot {
return false
} else {
return true
}
}
此外，我有一些路由，我需要在每个路由中调用getUserAgent函数，如果返回true，则使用我的路由，如果返回false，则返回其他内容。我该如何做到这一点？
路由：
func Routes(router *gin.Engine) {
router.GET("/user_agent", getUserAgent)
router.GET("/", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.html", nil)
})
router.GET("/:some_urls", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.html", nil)
})
categories := router.Group("/categories")
{
categories.GET("/", controller.GetAllCategories)
}
router.GET("/category_detail", controller.GetCategoriesById)
products := router.Group("/products")
{
products.GET("/", controller.GetAllProducts_by_multi_params)
}
...
英文:
I have a function that defines a user_agent:
func getUserAgent(c *gin.Context) bool {
ua := ua.Parse(c.Request.UserAgent())
if ua.Bot {
return false
} else {
return true
}
}
Also, I have routes, and I need to call getUserAgent in each route and if it true - use my routes , if false - return smth else. How can i do this?
Routes:
func Routes(router *gin.Engine) {
router.GET("/user_agent", getUserAgent)
router.GET("/", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.html", nil)
})
router.GET("/:some_urls", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.html", nil)
})
categories := router.Group("/categories")
{
categories.GET("/", controller.GetAllCategories)
}
router.GET("/category_detail", controller.GetCategoriesById)
products := router.Group("/products")
{
products.GET("/", controller.GetAllProducts_by_multi_params)
}

也许你可以将getUserAgent作为中间件，像下面这样：
每个路由器都会先经过getUserAgent，然后再运行处理程序。
router.Use(getUserAgent)
英文:
Maybe you can make the getUserAgent as middleware like below
every router will go into the getUserAgent first then run the handler.
router.Use(getUserAgent)
