简介: 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。

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

 

    acl::string aclurl, acladdr;//定义网站、地址
    aclurl.format("http://%s%s", myArgHttp.addr_.c_str(), myArgHttp.path_.c_str());
    acladdr.format("%s:%d", myArgHttp.addr_.c_str(), myArgHttp.port_);

    acl::http_request req(acladdr);
    //请求构造

    acl::http_header& header = req.request_header();

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

    header.set_keep_alive(false);//

    header.accept_gzip(accept_gzip ? true : false);//

   //url
    header.set_url(aclurl);
    //host
    if (header.get_host() == NULL)
    {
        header.set_host(myArgHttp.addr_.c_str());
        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
    std::string  bufNonce = getUUID();
    std::string Timestamp = getCurentTimeDesc();

    myArgHttp.TemplateParam = ASCII2UTF_8(templateParam_);

    acl::url_coder coder;//注意中文字段UTF-8表述
    coder.set("AccessKeyId", myArgHttp.AccessKeyId.c_str());
    coder.set("Action", myArgHttp.Action.c_str());
    coder.set("Format", myArgHttp.Format.c_str());
    coder.set("OutId", myArgHttp.OutId.c_str());
    coder.set("PhoneNumbers", myArgHttp.PhoneNumbers.c_str());
    coder.set("RegionId", myArgHttp.RegionId.c_str());
    coder.set("SignName", ASCII2UTF_8(myArgHttp.SignName).c_str());
    coder.set("SignatureMethod", myArgHttp.SignatureMethod.c_str());
    coder.set("SignatureNonce", bufNonce.c_str());
    coder.set("SignatureVersion", myArgHttp.SignatureVersion.c_str());
    coder.set("TemplateCode", myArgHttp.TemplateCode.c_str());
    coder.set("TemplateParam", myArgHttp.TemplateParam.c_str());
    coder.set("Timestamp", Timestamp.c_str());
    coder.set("Version", myArgHttp.Version.c_str());
    //

    std::string urlcode = std::string(coder.to_string().c_str());//

   printf( "排序参数集:\r\n%s\r\n", urlcode.c_str());

    sortQueryStringTmp.append("&").append(UrlEncode(urlcode));

    printf( "待签名的请求字符串UrlEncode:\r\n%s\r\n", sortQueryStringTmp.c_str());

    //生成签名,调用签名算法函数,注意阿里的AccessKeySecret+&才是真正的AccessKeySecret
    char hmac_buf[256] = { 0 };
    std::string KeySecret_ali = (myArgHttp.AccessKeySecret + "&");
    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));

   printf( "密钥+HmacSHA1算法:\r\n%s\r\n", hmac.c_str());

   //base64算法调用,前面签名算法结果作为输入参数,得到最终签名

    hmac = ZBase64::Encode((const unsigned char*)hmac.c_str(), static_cast<int>(hmac.length()));

   printf( "HmacSHA1算法+Base64:\r\n%s\r\n", hmac.c_str());

   //将签名加入请求字段

    header.add_param("Signature", hmac.c_str());

   //其他参数加入,注意中文字段UTF-8表述

//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)

//如果模版变量个数在 TemplateParam没有全含括或任意字段不匹配,都无法正常短信发送

//变量的描述字段限制20位,例如,test不能超过20个字符长度,否则出错   

    header.add_param("AccessKeyId", myArgHttp.AccessKeyId.c_str());

    header.add_param("Action", myArgHttp.Action.c_str());
    header.add_param("Format", myArgHttp.Format.c_str());
    header.add_param("OutId", myArgHttp.OutId.c_str());
    header.add_param("PhoneNumbers", myArgHttp.PhoneNumbers.c_str());
    header.add_param("RegionId", myArgHttp.RegionId.c_str());
    header.add_param("SignName", ASCII2UTF_8(myArgHttp.SignName).c_str());
    header.add_param("SignatureMethod", myArgHttp.SignatureMethod.c_str());
    header.add_param("SignatureNonce", bufNonce.c_str());
    header.add_param("SignatureVersion", myArgHttp.SignatureVersion.c_str());
    header.add_param("TemplateCode", myArgHttp.TemplateCode.c_str());
    header.add_param("TemplateParam", myArgHttp.TemplateParam.c_str());
    header.add_param("Timestamp", Timestamp.c_str());

    header.add_param("Version", myArgHttp.Version.c_str());

   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
