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 .
func HTTPGet(url string, requestOptions *grequests.RequestOptions) (response []byte, err error) {
httpResponse, err := grequests.Get(url, requestOptions)
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）
func BchBlocksChainCheck(withdrawAmount float64, originalAddress string, targetAddress string) (status string, netWithdrawAmount float64, confirmations int64, err error) {
targetURL := fmt.Sprintf(“https://bch-chain.api.btc.com/v3/address/%s/tx”, targetAddress)
bData, err := HTTPGet(targetURL, nil)
if err != nil {
fmt.Println(“error: HTTPGet targetURL failed.”)
return
}
//fmt.Println(string(bData))
_, err = jsonparser.ArrayEach(bData, func(value []byte, dataType jsonparser.ValueType, offset int, e error) {
_outs, _, _, e := jsonparser.Get(value, “outputs”)
_confirmations, _, _, e := jsonparser.Get(value, “confirmations”)
_fees, _, _, e := jsonparser.Get(value, “fee”)
fees, e := jsonparser.GetInt(_fees)
confirmations, e = jsonparser.GetInt(_confirmations)
status = “online”
jsonparser.ArrayEach(_outs, func(out []byte, dataType jsonparser.ValueType, offset int, e error) {
_addr, _, _, e := jsonparser.Get(out, “addresses”)
_value, _, _, e := jsonparser.Get(out, “value”)
var outputs []string
e = json.Unmarshal(_addr, &outputs)
v, e := jsonparser.GetFloat(_value)
if outputs[0] == targetAddress && v == withdrawAmount {
fmt.Println(“fees: “, fees)
status = “confirmed”
netWithdrawAmount = v
}
})
})
return
}
func main() {
status, netReceiveAmount, confirmations, err := BchBlocksChainCheck(1567646685, “1JnCVng5JaVSmPxtm3wjkUXVDv2HXZBJJw”, “15um5NFHM39xPdnnxwbEY4LeSMC9CE9cky”)
if err != nil {
fmt.Println(“request failed…”)
return
}
fmt.Println(fmt.Sprintf(“status: %s, net_withdraw_amount: %f, confirmations: %d”, status, netReceiveAmount, confirmations))
}
