Tollbooth是一个用Go语言编写的用来限制HTTP访问速度的中间件，可用来限制每个HTTP请求的传输速率。例如你可以不限制/的访问速率，但是可以针对/login限制每个IP每秒最多POST多少个请求。
Go程序中使用的方法：
package mainimport ( "github.com/didip/tollbooth" "net/http" "time")func HelloHandler(w http.ResponseWriter, req *http.Request) { w.Write([]byte("Hello, World!"))}func main() { // You can create a generic limiter for all your handlers // or one for each handler. Your choice. // This limiter basically says: allow at most 1 request per 1 second. limiter := tollbooth.NewLimiter(1, time.Second) // This is an example on how to limit only GET and POST requests. limiter.Methods = []string{"GET", "POST"} // You can also limit by specific request headers, containing certain values. // Typically, you prefetched these values from the database. limiter.Headers = make(map[string][]string) limiter.Headers["X-Access-Token"] = []string{"abc123", "xyz098"} // And finally, you can limit access based on basic auth usernames. // Typically, you prefetched these values from the database as well. limiter.BasicAuthUsers = []string{"bob", "joe", "didip"} // Example on how to wrap your request handler. http.Handle("/", tollbooth.LimitFuncHandler(limiter, HelloHandler)) http.ListenAndServe(":12345", nil)
