go语言 服务器接入小米支付SDK

服务器需要接入小米支付， 但是官网只有java和php版本，因此签名解析需要自己写

实行步骤：

1. 用eclipse打开java版本支付用例，加入mainClass文件，代码如下：

package com.xiaomi.migc.server.sdk;import java.io.File;import java.util.HashMap;import java.util.Map;public class mainClass {private static String getSign(Map params) throws Exception{String signString = ParamUtil.getSortQueryString(params);return HmacSHA1Encryption.hmacSHA1Encrypt(signString, "QFehjb0X8qEhbkpi380GTQ=1");} public static void main(String args[]){ Map mapInfo = new HashMap(); mapInfo.put("appId", "2882303761517239138"); mapInfo.put("cpOrderId", "9786bffc-996d-4553-aa33-f7e92c0b29d5"); mapInfo.put("orderConsumeType", "10"); mapInfo.put("orderId", "21140990160359583390"); mapInfo.put("orderStatus", "TRADE_SUCCESS"); mapInfo.put("payFee", "1"); mapInfo.put("payTime", "2014-09-05%2015:20:27"); mapInfo.put("productCode", "com.demo_1"); mapInfo.put("productCount", "1"); mapInfo.put("productName", "银子1两"); mapInfo.put("uid", "100010"); try {System.out.println(mainClass.getSign(mapInfo));} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();} }}

2. 编写golang代码，并测试，代码如下：

package mainimport ("crypto/hmac""crypto/sha1""fmt""net/url""sort")func CheckXiaoMiPay(urlInfo url.Values) bool {mapKeyInfo := map[string]string{}var slKeys sort.StringSlicefor key, _ := range urlInfo {if key == `signature` {continue}mapKeyInfo[key] = urlInfo.Get(key)slKeys = append(slKeys, key)}//check successslKeys.Sort()var sText stringfor _, key := range slKeys {sText = sText + key + `=` + mapKeyInfo[key] + `&`}if len(sText) != 0 {sText = sText[:len(sText)-1]}sEncrypt := getEncryptKey(sText, "QFehjb0X8qEhbkpi380GTQ=1")fmt.Println(sEncrypt)return sEncrypt == urlInfo.Get(`signature`)}func getEncryptKey(sText string, appSecret string) string {mac := hmac.New(sha1.New, []byte(appSecret))mac.Write([]byte(sText))slBytes := mac.Sum(nil)if slBytes == nil {return ``}var strRtn stringfor _, aByte := range slBytes {strRtn = strRtn + fmt.Sprintf("%02x", aByte)}return strRtn}func main() {urlData := url.Values{"appId":            []string{"2882303761517239138"},"cpOrderId":        []string{"9786bffc-996d-4553-aa33-f7e92c0b29d5"},"orderConsumeType": []string{"10"},"orderId":          []string{"21140990160359583390"},"orderStatus":      []string{"TRADE_SUCCESS"},"payFee":           []string{"1"},"payTime":          []string{"2014-09-05%2015:20:27"},"productCode":      []string{"com.demo_1"},"productCount":     []string{"1"},"productName":      []string{"银子1两"},"uid":              []string{"100010"},"signature":        []string{"121f401e6e92fa8d8bb45392b8102891a058c1be"},}fmt.Println(CheckXiaoMiPay(urlData))}

经过测试打印为true，服务器程序只需要复制上面俩个函数，即可对签名进行确认。
