区块链教程之基础开发通过接口查询币种提币情况bch

代码如下

package main

import (

"encoding/json"

"fmt"

"github.com/buger/jsonparser"

"github.com/levigross/grequests"

)

// HTTPGet .

if err == nil {

if httpResponse.StatusCode == 200 {

response = httpResponse.Bytes()

}

return

}

// BchBlocksChainCheck 根据提币的数量，提币方地址以及目标方地址来检查提币是否已经confirmed.

// 返回值有两个：提币状态以及已收到的提币数量（扣除手续费）

if err != nil {

fmt.Println("error: HTTPGet targetURL failed.")

return

}

//fmt.Println(string(bData))
