在解析*http.Request
对象并将其转发到Gorilla mux router处理程序之前,是否有办法捕获它?
例如,我们有一些带有其处理程序的路由图:
r := mux.NewRouter()
r.HandleFunc("/products/{key}", ProductHandler)
r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
我计划使用动态语言前缀(2个符号)。示例:
没有语言代码(用于默认语言选项):
https://example.com/products/1
https://example.com/articels/2
使用语言代码:
https://example.com/ru/products/1
https://example.com/ru/articels/2
是否有办法在中间件中捕获完整的URL,提取语言(如果存在),然后在进行一些修改后将其传递给Gorilla多路复用器路由器?这将有助于建立漂亮的URL:
https://example.com/products/1 <- default language
https://example.com/ru/products/1 <- russian language (same resource but in different language)
看起来比这个变体更具吸引力:
https://example.com/en/products/1 <- mandatory default language
https://example.com/ru/products/1 <- russian language
类似的事情可能会起作用:
r := mux.NewRouter()
r.HandleFunc("/products/{key}", ProductHandler)
r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
m := http.NewServeMux()
m.HandeFunc("/", func(w http.ResponseWriter, req *http.Request) {
// do something with req
r.ServeHTTP(w, req)
})
http.ListenAndServe(":8080", m)
