1、说明

############################################ 发该贴时签名实现方式粗糙，后边进行了改善并封装了阿里大鱼的sdk 看帖的朋友请移步alidayujs-demo 或者看npm的插件alidayujs ############################################

2、代码实现

生成sign

    /**
 * 根据淘宝官网提供的教程
 * http://open.taobao.com/doc2/detail.htm?articleId=101617&docType=1&treeId=1
 */
var md5 = require("blueimp-md5");

// 淘宝应用App信息(换成自己的)
var config = {
    AppKey: '233002**',
    AppSecret: '3403636b338e100399**'
};
exports.config=config;

var dySign = function (obj) {
    // 生成时间戳
    var time = new Date();
    var timestamp = time.getFullYear()  + "-" +
        ("0" + (time.getMonth() + 1)).slice(-2) + "-" +
        ("0" + time.getDate()).slice(-2) + ' '  +
        ("0" + time.getHours()).slice(-2)   + ":" +
        ("0" + time.getMinutes()).slice(-2) + ":" +
        ("0" + time.getSeconds()).slice(-2);
    obj.timestamp = timestamp;

    // 程序key
    obj.app_key = config.AppKey;
    
    // 参数数组
    var arr = [];
    // 循环添加参数项
    for(var p in obj){
        arr.push(p + obj[p]);
    }
    // 2、按首字母升序排列
    arr.sort();
    // 3、连接字符串
    var msg =  arr.join('');
    // console.log(msg);

    // 生成签名 sign hmac
    var sign = md5(msg, config.AppSecret);

    // 返回
    return sign.toUpperCase();
}

module.exports.dySign = dySign;

拼接字符串并发送请求

    var signGenerate = require('./create_dysign');
var http = require('http');
var qs = require('querystring');

var alidayuUrl = 'http://gw.api.taobao.com/router/rest';
// 短信发送的参数对象
var obj = {
    format: 'json',
    method: 'alibaba.aliqin.fc.sms.num.send',
    v: '2.0',
    timestamp: '2016-1-16 02:33:30',
    partner_id: 'top-sdk-nodejs-20160116',
    rec_num: '15110****', //手机号多个以逗号间隔
    sign_method: 'hmac',
    sms_type: 'normal',
    sms_param: '{"code":"giscafer","product":"alidayu短信测试"}',
    sms_free_sign_name: '身份验证',
    sms_template_code: 'SMS_4725038'
}
//生成签名并拼接请求参数链接
var sign = signGenerate.dySign(obj);
console.log('签名：', sign);

obj.sign = sign;
obj.app_key = signGenerate.config.AppKey;
var arr = [];
for (var p in obj) {
    arr.push(p + '=' + obj[p]);
}
var msg = arr.join('&')
var sendurl = alidayuUrl + '?' + msg;
console.log('完成请求地址：' + sendurl);

/**
 * 短信发送请求测试
 */
var params = qs.stringify(obj);
var options = {
    hostname: 'gw.api.taobao.com',
    port: 80,
    path: '/router/rest?' + params,
    method: 'GET'
};
var req = http.request(options, function (res) {
    console.log('STATUS: ' + res.statusCode);
    // console.log('HEADERS: ' + JSON.stringify(res.headers));
    // console.log(req.path);
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log('RESULT: ' + chunk);
    });
});

req.on('error', function (e) {
    console.log('ERROR: ' + e.message);
});

// write data to request body
req.write("执行完毕！");

req.end();

请求结果

{"alibaba_aliqin_fc_sms_num_send_response":{"result":{"err_code":"0","model":"100545278271^1100912293896","success":true},"request_id":"15q8um2g8w8ef"}}
