Golang 语言版本奇亚(Chia, XCH) 接口之获取主链相关信息(含最新块高)

关于如何使用 curl 命令来获取奇亚(Chia, XCH) 接口之获取主链相关信息(含最新块高)，请移步 https://www.twle.cn/t/19316#reply0

这里只贴上 Golang 使用 net/http 包来实现的版本

package main

import (
    "bytes"
    "crypto/tls"
    "crypto/x509"
    "encoding/json"
    "fmt"
    "io/ioutil"
    "net/http"
)

const url = "https://localhost:8555/get_blockchain_state"

func main() {

    pool := x509.NewCertPool()

    cliCrt, err := tls.LoadX509KeyPair("/Users/yufei/.chia/mainnet/config/ssl/full_node/private_full_node.crt",
        "/Users/yufei/.chia/mainnet/config/ssl/full_node/private_full_node.key")

    if err != nil {

        fmt.Println("Loadx509keypair err:", err)

        return

    }

    tr := &http.Transport{

        TLSClientConfig: &tls.Config{

            RootCAs: pool,

            Certificates:       []tls.Certificate{cliCrt},
            InsecureSkipVerify: true, //跳过验证服务端证书

        },
    }

    client := &http.Client{Transport: tr}

    data := make(map[string]string)
    b, _ := json.Marshal(data)

    resp, err := client.Post(url,
        "application/json",
        bytes.NewBuffer(b))
    if err != nil {
        fmt.Println(err)
    }
    defer resp.Body.Close()
    body, _ := ioutil.ReadAll(resp.Body)
    fmt.Println(string(body))
}

重点有两个地方

设置证书

pool := x509.NewCertPool()

cliCrt, err := tls.LoadX509KeyPair("/Users/yufei/.chia/mainnet/config/ssl/full_node/private_full_node.crt",
    "/Users/yufei/.chia/mainnet/config/ssl/full_node/private_full_node.key")

if err != nil {

    fmt.Println("Loadx509keypair err:", err)

    return

}

设置不检查客户端证书和服务器证书

tr := &http.Transport{

    TLSClientConfig: &tls.Config{

        RootCAs: pool,

        Certificates:       []tls.Certificate{cliCrt},
        InsecureSkipVerify: true, //跳过验证服务端证书

    },
}

client := &http.Client{Transport: tr}

输出结果如下
