Linux：ab 发送 POST、PUT 请求

---

ab 可以发送 GET、HEAD、POST、PUT 请求，但是不支持模拟 DELETE 等 Method 的请求。

https://stackoverflow.com/questions/10601821/apache-bench-how-to-force-put-delete-and-post-method

From the manual page:
-i Do HEAD requests instead of GET.
-p POST-file File containing data to POST. Remember to also set -T.
-u PUT-file File containing data to PUT. Remember to also set -T.
But no DELETE, et al.

使用 golang 实现简版服务端，Dump Request：

package main

import (
	"fmt"
	"net/http"
	"net/http/httputil"
)

func main() {
	http.HandleFunc("/", handle)
	http.ListenAndServe(":1280", nil)
}

func handle(w http.ResponseWriter, r *http.Request) {
	req, err := httputil.DumpRequest(r, true)
	if err != nil {
		panic(err)
	}

	fmt.Printf("%s\n", req)
}

执行命令，启动服务端：

$ go run main.go
