短信验证码接入----腾讯云短信
作者：互联网
最近因为公司项目需要接入短信验证码功能，在网上转了几圈，最终选定了2家公司；一家是腾讯云的短信业务，这个是收费的。另一个是Mob的短信业务，这个是免费的。
本篇文章主要是介绍腾讯云的接入，后面一章节会介绍Mob的接入方法。
腾讯云的接入文档参考地址：
https://cloud.tencent.com/document/product/382/5976
参数问题和错误码等直接看文档，下面我们说说流程。
首先是需要去腾讯云注册账号，然后做个人或者公司的实名认证。通过之后再注册应用，应用也是需要通过认证来申请短信模板的；
注册地址如下：https://console.cloud.tencent.com/sms/smslist
创建应用之后如下：https://console.cloud.tencent.com/sms/smsinfo/1400248333/0
这里是应用的管理后台，可以查看很多信息。管理短信模板等。一样的是ID和key：
验证流程是，手机端生成验证码，并本地保存，好后面做验证；然后把手机号和验证码通过Http的json格式的数据发生给TX，TX校验通过之后，会把验证码发给对应手机号。TX本身是不生成验证码和做校验的。验证码生成和校验都是需要我们自己做的。手机端收到验证码之后，和之前的缓存做对比，本地判断是否验证成功。TX的作用就是一个短信息的发送。我们的测试环境是cocos2dx3.16，用的是cocos的http和json解析。
下面我们看看详细的接入代码：
引入头文件：
#include "network/HttpClient.h"
#include "json/rapidjson.h"
#include "json/document.h"
#include "json/stringbuffer.h"
#include "json/writer.h"
//------------函数声明------------
//生成本地验证码
int CreateCode();
//发送TX短信验证码
void SendSMSCode();
//拼接TX需要的JSON格式的数据，并做哈希加密
std::string getJsonData();
//TX回复的消息处理
void onRequestCompleted(cocos2d::network::HttpClient* sender, cocos2d::network::HttpResponse* response);
//哈希函数
char* StrSHA256(const char* str, long long length, char* sha256);
int m_smsCode;
std::string m_phoneNum;
//------------函数实现------------
//生成本地验证码
int LoginScene::CreateCode()
{
srand(time(NULL));
int _num = 100000 + rand() % 999999;
log("-----SMS Code:%d", _num);
return _num;
}
//拼接json数据
std::string LoginScene::getJsonData()
{
auto _now = system_clock::to_time_t(system_clock::now());
int _time = (int)_now;//UNIX 时间戳
string strMobile = m_phoneNum; //tel 的 mobile 字段的内容
string strAppKey = "3687c053222838ef80a00b2e4cc6ba"; //sdkappid 对应的 appkey，需要业务方高度保密
string strRand = "7326249334"; //URL 中的 random 字段的值
string strTime = std::to_string(_time); //UNIX 时间戳
string sig = ""; //string sig = sha256(appkey=3687c053222838ef80a00b2e4cc6ba85&random=7226249334&time=1457336869&mobile=18012345678)

VS2013加密输出信息：
经过第三方网站加密输出对比：http://www.atool9.com/hash.php
我们加密出来的哈希值和三方网站的是相同的。剩下的就是本地保存的验证码，和手机收到的码做比较，判断校验是否通过。
