Hello @zkcrescent,
Welcome to the Kratos repository! I'm Dosu, a bot here to assist you. While we wait for a human maintainer to respond, feel free to ask me anything regarding solving bugs, answering questions, or even becoming a contributor. I'm here to assist you in the meantime.
在Kratos框架中,您可以使用中间件来打印所有请求路由,包括被拦截的或者没有content type被拦截的请求。中间件是一系列处理器的链,可以在请求到达最终处理器之前处理这些请求。在您的情况下,您可以创建一个中间件来记录所有传入的请求。
在提供的上下文中,已经定义了三个中间件函数:corsFilter
,authFilter
和loggingFilter
。每个函数都会记录请求的方法和URI。您可以修改这些函数以记录更多信息。
以下是如何修改loggingFilter
以记录关于请求的更多信息的示例:
func loggingFilter(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
// Log the method, URI, and content type of the request
log.Println("logging:", r.Method, r.RequestURI, r.Header.Get("Content-Type"))
// Call the next handler, which can be another middleware in the chain, or the final handler.
next.ServeHTTP(w, r)
})
}
在TestRoute
函数中,使用Filter
函数将loggingFilter
添加到服务器:
srv := NewServer(
Filter(corsFilter, loggingFilter),
)
这意味着loggingFilter
将应用于服务器处理的所有请求。因此,所有请求,包括被拦截的或者没有content type被拦截的请求,都将被记录。
Kratos框架通过使用Router结构来处理由protobuf生成的HTTP路由。Router结构有一个名为Handle的方法,该方法使用URL路径和方法的匹配器注册新路由。
Handle方法接受HTTP方法,相对路径,HandlerFunc和可选的过滤器。HandlerFunc是一个服务HTTP请求的函数。过滤器是可以修改HTTP请求或响应的函数。
Router结构还有每个HTTP方法(GET,POST,PUT,PATCH,DELETE,CONNECT,OPTIONS,TRACE)的便利方法,这些方法使用适当的HTTP方法调用Handle方法。
Kratos框架通过使用中间件来处理被拦截的请求。Kratos中的中间件是一系列处理器的链,每个处理器决定是否将请求传递给链中的下一个处理器。
在提供的上下文中,使用Invoke
方法进行远程过程调用。此方法创建一个新的HTTP请求并设置必要的头。然后使用transport.NewClientContext
函数更新请求的上下文。
然后调用invoke
方法,该方法使用中间件链来处理请求。使用middleware.Chain
函数创建中间件链,该函数接受一系列中间件函数并返回一个新的中间件函数,该函数按照提供的顺序调用每个中间件函数。
希望这些信息对您有所帮助。如果您有任何其他问题或需要进一步的澄清,请随时告诉我。
