最近在调用阿里云短信服务接口发现并没有c++的资料，网上查询发现也是零星描述，由于自身项目基础累积了C++的太多，不想掺杂太多语言，就自行实现c++的阿里云短信接口，其难点就在于签名而已，希望能给大家提供参考。
1）我的网页调用接口采用acl_master实现的，acl_master是一个跨平台c/c++库，提供了网络通信库及服务器编程框架，同时提供更多的实用功能库及示例。（下载地址：Github: https://github.com/acl-dev/acl），读者可采用其他库实现。
2）参考阿里云的“HTTP协议及签名”（https://help.aliyun.com/document_detail/56189.html?spm=a2c4g.11186623.6.581.fy2faU）描述文档，先做一些必要的准备：
*注册阿里云，有需要的阿里云产品通用代金券的可以点击下面链接进行领取：
https://promotion.aliyun.com/ntms/yunparter/invite.html?userCode=pfb80n4a
开通短信服务后，在你账户头像下AccessKeys选项进入用户信息管理界面，获取到你的AccessKeyId和AccessKeySecret，具体请参考阿里云短信服务的资料完成操作
*根据"http协议及签名”描述文档，定义了短信请求参数结构,初始化中带*的请自行写入自己实际参数：
struct HttpMsgArg
{
HttpMsgArg()
: addr_("dysmsapi.aliyuncs.com")
, path_("")
, port_(80)
//
, AccessKeyId("********")
, AccessKeySecret("***************")
, Timestamp("2018-04-13T10:10:10Z")
, Format("XML")
, SignatureMethod("HMAC-SHA1")
, SignatureVersion("1.0")
, SignatureNonce("1")
, Signature("")
//
, Action("SendSms")
, Version("2017-05-25")
, RegionId("cn-hangzhou")
, PhoneNumbers("137********")
, SignName("短信测试")
, TemplateCode("SMS_*******")
, TemplateParam("")
, SmsUpExtendCode("")
, OutId("123")
{
};
//
std::string addr_; // web 服务器地址
std::string path_; // 本地请求的数据文件
int port_;
//
std::string AccessKeyId; //
std::string AccessKeySecret; //
std::string Timestamp; //格式为：yyyy-MM-dd’T’HH:mm:ss’Z’；时区为：GMT
std::string Format; //没传默认为JSON，可选填值：XML
std::string SignatureMethod; //建议固定值：HMAC-SHA1
std::string SignatureVersion; //建议固定值：1.0
std::string SignatureNonce; //用于请求的防重放攻击，每次请求唯一，JAVA语言建议用：java.util.UUID.randomUUID()生成即可
std::string Signature; //最终生成的签名结果值
std::string Action; //API的命名，固定值，如发送短信API的值为：SendSms
std::string Version; //API的版本，固定值，如短信API的值为：2017-05-25
std::string RegionId; //API支持的RegionID，如短信API的值为：cn-hangzhou
/*
*短信接收号码,支持以逗号分隔的形式进行批量调用，
*批量上限为1000个手机号码,批量调用相对于单条调用及时性稍有延迟,
*验证码类型的短信推荐使用单条调用的方式
*/
std::string PhoneNumbers;
std::string SignName; //短信签名
std::string TemplateCode; //短信模板ID
/*
短信模板变量替换JSON串,友情提示:如果JSON中需要带换行符,请参照标准的JSON协议。
*/
std::string TemplateParam;
std::string SmsUpExtendCode; //上行短信扩展码,无特殊需要此字段的用户请忽略此字段
std::string OutId; //外部流水扩展字段
};*url格式转换需求：
unsigned char ToHex(unsigned char x)
{
return x > 9 ? x + 55 : x + 48;
}
unsigned char FromHex(unsigned char x)
{
unsigned char y;
if (x >= 'A' && x <= 'Z') y = x - 'A' + 10;
else if (x >= 'a' && x <= 'z') y = x - 'a' + 10;
else if (x >= '0' && x <= '9') y = x - '0';
else assert(0);
return y;
}
std::string UrlEncode(const std::string& str)
{
std::string strTemp = "";
size_t length = str.length();
for (size_t i = 0; i < length; i++)
{
if (isalnum((unsigned char)str[i]) ||
(str[i] == '-') ||
(str[i] == '_') ||
(str[i] == '.') ||
(str[i] == '~'))
strTemp += str[i];
else if (str[i] == ' ')
strTemp += "+";
else
{
strTemp += '%';
strTemp += ToHex((unsigned char)str[i] >> 4);
strTemp += ToHex((unsigned char)str[i] % 16);
}
}
return strTemp;
}
std::string UrlDecode(const std::string& str)
{
std::string strTemp = "";
size_t length = str.length();
for (size_t i = 0; i < length; i++)
{
if (str[i] == '+') strTemp += ' ';
else if (str[i] == '%')
{
assert(i + 2 < length);
unsigned char high = FromHex((unsigned char)str[++i]);
unsigned char low = FromHex((unsigned char)str[++i]);
strTemp += high * 16 + low;
}
else strTemp += str[i];
}
return strTemp;
}*UUID的生成实现函数：
std::string getUUID() {
#ifdef WIN32
char buffer[GUID_LEN] = { 0 };
GUID guid;
if (CoCreateGuid(&guid))
{
fprintf(stderr, "create guid error\n");
return "";
}
_snprintf(buffer, sizeof(buffer),
"%08X-%04X-%04x-%02X%02X-%02X%02X%02X%02X%02X%02X",
guid.Data1, guid.Data2, guid.Data3,
guid.Data4[0], guid.Data4[1], guid.Data4[2],
guid.Data4[3], guid.Data4[4], guid.Data4[5],
guid.Data4[6], guid.Data4[7]);
printf("guid: %s\n", buffer);
return std::string(buffer);
#else
uuid_t uuid;
uuid_generate(uuid);
char buf[64] = { 0 };
uuid_unparse(uuid, buf);
return std::string(buf);
#endif
};*用于ascii和utf-8的字符格式转换，一些其他的格式转换也一并给出，防止特定需要，主要是阿里参数中文可能需要用到

3）准备工作完成，开始短信申请全过程，本人借助acl-master库实现，用其他网页访问接口的请斟酌参考

//访问类型为Get
header.set_method(acl::HTTP_METHOD_GET);

header.set_url(aclurl);
//host
if (header.get_host() == NULL)

printf(">>>set host: %s\r\n", myArgHttp.addr_.c_str());
}
else
printf(">>>host: %s\r\n", header.get_host());
//签名内容缓存
std::string sortQueryStringTmp = "";
sortQueryStringTmp.append("GET&").append(UrlEncode("/"));
//签名内容项,参数key的字符串排序

hmac_sha((char*)(ASCII2UTF_8(KeySecret_ali)).c_str(), (int)KeySecret_ali.length()
, (char*)ASCII2UTF_8(sortQueryStringTmp).c_str(), (int)sortQueryStringTmp.length(), hmac_buf, 20);
std::string hmac = std::string(hmac_buf,strlen(hmac_buf));

//TemplateParam，例如，"{\"customer\":\"test\"}"，
//进行传输短信的变量与你阿里短信服务模版的变量一致，（如都存在”customer“变量）

bool rc = req.request(NULL, 0);//http请求
// 将 build_request 放在 req.request 后面，是因为
// req.request 内部可能会修改请求头中的字段
acl::string hdr;
header.build_request(hdr);
printf("request header:\r\n%s\r\n", hdr.c_str());
if (rc == false)
{
printf( "send request error");
return;
}
printf("send request ok!\r\n");
// 取出 HTTP 响应头的 Content-Type 字段
const char* p = req.header_value("Content-Type");
if (p == NULL || *p == 0)
{
printf( "no Content-Type");
return;
}
// 分析 HTTP 响应头的数据类型
acl::http_ctype content_type;
content_type.parse(p);
// 响应头数据类型的子类型
const char* stype = content_type.get_stype();
bool ret;
if (stype != NULL)
ret = do_plain(req);
if (ret == true)
printf("read ok!");
4）最终呈现效果
图二的签名与图一部一致是因为两张图片分别来自两个请求的截图
5）阿里云短信接口的http实现关键是做好签名，然后按通用的http访问请求实现即可,另外需要特别注意的是注意阿里里面短信定义要求，例如变量不能包含限制字符，变量长度不能超过20等等
