将下面代码改为GO代码host = 'https://kuaidi100.market.alicloudapi.com' path = '/getExpress' method = 'GET' appcode = '你自己的AppCode' querys = 'NO=12345678&TYPE=yuantong' bodys = {} url = host + path + '?' + querys request = urllib2.Request(url) request.add_header('Authorization', 'APPCODE ' + appcode) ctx = ssl.create_default_context() ctx.check_hostname = False ctx.verify_mode = ssl.CERT_NONE response = urllib2.urlopen(request, context=ctx) content = response.read() if (content): print(content)

以下是将代码改为GO代码的示例：

package main

import (
	"fmt"
	"net/http"
	"io/ioutil"
)

func main() {
	host := "https://kuaidi100.market.alicloudapi.com"
	path := "/getExpress"
	method := "GET"
	appcode := "你自己的AppCode"
	querys := "NO=12345678&TYPE=yuantong"
	url := host + path + "?" + querys

	req, err := http.NewRequest(method, url, nil)
	if err != nil {
		fmt.Println(err)
		return
	}

	req.Header.Add("Authorization", "APPCODE " + appcode)

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		fmt.Println(err)
		return
	}
	defer res.Body.Close()

	body, err := ioutil.ReadAll(res.Body)
	if err != nil {
		fmt.Println(err)
		return
	}

	fmt.Println(string(body))
}

请注意，由于GO语言的标准库中已经包含了HTTP客户端，因此我们不需要像Python中一样使用`urllib2`和`ssl`模块，而是直接使用GO语言的`http`包发送HTTP请求，并使用`ioutil`包读取响应内容。
