golang的GET请求(类似于PHP的CURL)

check_url := "https://www.baidu.com"

    header := make(map[string]string)

    res, err := util.Hpool.Request(check_url, http.MethodGet, "", header)

    if err != nil {

        return nil, err

    }

    spew.Dump(res)

【http.go】

package util

import (

    "bytes"

    "io/ioutil"

    "net/http"

    "time"

)

type HttpConPool struct {

    Conn *http.Client

    Hpool = new(HttpConPool)

        Transport: &http.Transport{

            MaxIdleConnsPerHost: Str2Int(GetConfigValue("http", "max_conn")),

        },

        Timeout: time.Duration(Str2Int(GetConfigValue("http", "timeout"))) * time.Millisecond,

    }

}

func (h *HttpConPool) Request(url string, method string, data string, header map[string]string) (interface{}, error) {

    req, err := http.NewRequest(method, url, bytes.NewBuffer([]byte(data)))

    if err != nil {

        return nil, err

    }

    for h, v := range header {

        req.Header.Set(h, v)

    }
