golang有用的库及工具 之 fasthttp客户端 最通用最有效最简单使用方式

fasthttp 是go语言中最常用性能最好的http请求库。

那么如何使用fasthttp 客户端调用http请求。

常用http kv请求：

//http请求
func doTimeout(arg *fasthttp.Args, method string, requestURI string, cookies map[string]interface{}) ([]byte, int, error) {
   req := &fasthttp.Request{}
   switch method {
   case "GET":
      req.Header.SetMethod(method)
      // 拼接url
      requestURI = requestURI + "?" + arg.String()
   case "POST":
      req.Header.SetMethod(method)
      arg.WriteTo(req.BodyWriter())
   }
   if cookies != nil {
      for key, v := range cookies {
         req.Header.SetCookie(key, v.(string))
      }
   }
   req.SetRequestURI(requestURI)

   resp := &fasthttp.Response{}
   err := gCli.DoTimeout(req, resp, time.Second*30)

   return resp.Body(), resp.StatusCode(),  err
}

json body 使用：

func doJsonTimeout(method string, url, bodyjson string) ([]byte, int, error) {
   req := &fasthttp.Request{}
   resp := &fasthttp.Response{}

   switch method {
   case "GET":
      req.Header.SetMethod(method)
   case "POST":
      req.Header.SetMethod(method)
   }

   req.Header.SetContentType("application/json")
   req.SetBodyString(bodyjson)

   req.SetRequestURI(url)

   err := gCli.DoTimeout(req, resp, time.Second*30)
   return resp.Body(), resp.StatusCode(),  err
}

test:

func main() {
   var arg = &fasthttp.Args{}
   arg.Set("hello","world")
   fmt.Println(doTimeout(arg, "GET","http://127.0.0.1/hello",nil))
   fmt.Println(doJsonTimeout("GET","http://127.0.0.1/hello","{\"hello\":\"world\"}"))
}
