阿里云短信服务接口的c++实现

日期：2018-04-25点击：374

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

 *阿里云短信接口参数的时间格式要求：

std::string getCurentTimeDesc() { time_t _t = time(NULL); char bufTime[64] = { 0 }; struct tm* _tt; //localtime_s(&_tt, &_t);//系统本地时间 _tt = gmtime(&_t);//格林时间 _tt->tm_year += 1900; _tt->tm_mon += 1; sprintf(bufTime, "%04d-%02d-%02dT%02d:%02d:%02dZ" , _tt->tm_year,_tt->tm_mon,_tt->tm_mday,_tt->tm_hour,_tt->tm_min,_tt->tm_sec); return std::string(bufTime); }

 *重点一，签名算法实现，来源网上公开的一些资料，经过实践实用c语言函数

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
