golang (5) http 请求分析

http 分析包分析

https  客户端跳过http认证

golang http请求server的https文件，出现错误

error: certificate signed by unknown authority，

go的Client端默认要对服务端传过来的数字证书进行校验的，如果这个证书是由不知名CA签发的，则会出先上面的错误。联想到curl的-k选项，可以跳过对服务端认证的认证。

修改client.go的代码，让client端略过对证书的校验，如下：

package main

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

func main() {
    tr := &http.Transport{
        TLSClientConfig:    &tls.Config{InsecureSkipVerify: true},
    }
    client := &http.Client{Transport: tr}
    resp, err := client.Get("https://localhost:8081")

    if err != nil {
        fmt.Println("error:", err)
        return
    }
    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)
    fmt.Println(string(body))
}
