PHP 签名示例

<?php// 确定 App 的云 API 密钥$secret_id = "XXXXXXXXXXXXXXXXXX";$secret_key = "AAAAAAAAAAAAAAAAAAA";
// 确定签名的当前时间和失效时间$current = time();$expired = $current + 86400;  // 签名有效期：1天
// 向参数列表填入参数$arg_list = array(    "secretId" => $secret_id,    "currentTimeStamp" => $current,    "expireTime" => $expired,    "random" => rand());
// 计算签名$original = http_build_query($arg_list);$signature = base64_encode(hash_hmac('SHA1', $original, $secret_key, true).$original);
echo $signature;echo "\n";?>

Java 签名示例

import java.util.Random;import javax.crypto.Mac;import javax.crypto.spec.SecretKeySpec;import sun.misc.BASE64Encoder;
// 签名工具类class Signature {    private String secretId;    private String secretKey;    private long currentTime;    private int random;    private int signValidDuration;
    private static final String HMAC_ALGORITHM = "HmacSHA1"; //签名算法    private static final String CONTENT_CHARSET = "UTF-8";
    public static byte[] byteMerger(byte[] byte1, byte[] byte2) {        byte[] byte3 = new byte[byte1.length + byte2.length];        System.arraycopy(byte1, 0, byte3, 0, byte1.length);        System.arraycopy(byte2, 0, byte3, byte1.length, byte2.length);        return byte3;    }
    // 获取签名    public String getUploadSignature() throws Exception {        String strSign = "";        String contextStr = "";
        // 生成原始参数字符串        long endTime = (currentTime + signValidDuration);        contextStr += "secretId=" + java.net.URLEncoder.encode(secretId, "utf8");        contextStr += "&currentTimeStamp=" + currentTime;        contextStr += "&expireTime=" + endTime;        contextStr += "&random=" + random;
        try {            Mac mac = Mac.getInstance(HMAC_ALGORITHM);            SecretKeySpec secretKey = new SecretKeySpec(this.secretKey.getBytes(CONTENT_CHARSET), mac.getAlgorithm());            mac.init(secretKey);
            byte[] hash = mac.doFinal(contextStr.getBytes(CONTENT_CHARSET));            byte[] sigBuf = byteMerger(hash, contextStr.getBytes("utf8"));            strSign = base64Encode(sigBuf);            strSign = strSign.replace(" ", "").replace("\n", "").replace("\r", "");        } catch (Exception e) {            throw e;        }        return strSign;    }
    private String base64Encode(byte[] buffer) {        BASE64Encoder encoder = new BASE64Encoder();        return encoder.encode(buffer);    }
    public void setSecretId(String secretId) {        this.secretId = secretId;    }
    public void setSecretKey(String secretKey) {        this.secretKey = secretKey;    }
    public void setCurrentTime(long currentTime) {        this.currentTime = currentTime;    }
    public void setRandom(int random) {        this.random = random;    }
    public void setSignValidDuration(int signValidDuration) {        this.signValidDuration = signValidDuration;    }}
public class Test {    public static void main(String[] args) {        Signature sign = new Signature();        // 设置 App 的云 API 密钥        sign.setSecretId("个人 API 密钥中的 Secret Id");        sign.setSecretKey("个人 API 密钥中的 Secret Key");        sign.setCurrentTime(System.currentTimeMillis() / 1000);        sign.setRandom(new Random().nextInt(java.lang.Integer.MAX_VALUE));        sign.setSignValidDuration(3600 * 24 * 2); // 签名有效期：2天
        try {            String signature = sign.getUploadSignature();            System.out.println("signature : " + signature);        } catch (Exception e) {            System.out.print("获取签名失败");            e.printStackTrace();        }    }}

对于 Java1.9 以上的版本，已经移除了sun.misc.BASE64Encoder相关的包，可以使用java.util.Base64替换base64Encode方法中对应的实现，具体请参考如下代码：

import java.util.Base64;
private String base64Encode(byte[] buffer) {    Base64.Encoder encoder = Base64.getEncoder();    return encoder.encodeToString(buffer);}

Node.js 签名示例

var querystring = require("querystring");var crypto = require('crypto');
// 确定 app 的云 API 密钥var secret_id = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";var secret_key = "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA";
// 确定签名的当前时间和失效时间var current = parseInt((new Date()).getTime() / 1000)var expired = current + 86400;  // 签名有效期：1天
// 向参数列表填入参数var arg_list = {    secretId : secret_id,    currentTimeStamp : current,    expireTime : expired,    random : Math.round(Math.random() * Math.pow(2, 32))}
// 计算签名var orignal = querystring.stringify(arg_list);var orignal_buffer = new Buffer(orignal, "utf8");
var hmac = crypto.createHmac("sha1", secret_key);var hmac_buffer = hmac.update(orignal_buffer).digest();
var signature = Buffer.concat([hmac_buffer, orignal_buffer]).toString("base64");
console.log(signature);

C# 签名示例

using System;using System.Security.Cryptography;using System.Text;using System.Threading;
class Signature{    public string m_strSecId;    public string m_strSecKey;    public int m_iRandom;    public long m_qwNowTime;    public int m_iSignValidDuration;    public static long GetIntTimeStamp()    {        TimeSpan ts = DateTime.UtcNow - new DateTime(1970, 1, 1);        return Convert.ToInt64(ts.TotalSeconds);    }    private byte[] hash_hmac_byte(string signatureString, string secretKey)    {        var enc = Encoding.UTF8; HMACSHA1 hmac = new HMACSHA1(enc.GetBytes(secretKey));        hmac.Initialize();        byte[] buffer = enc.GetBytes(signatureString);        return hmac.ComputeHash(buffer);    }    public string GetUploadSignature()    {        string strContent = "";        strContent += ("secretId=" + Uri.EscapeDataString((m_strSecId)));        strContent += ("&currentTimeStamp=" + m_qwNowTime);        strContent += ("&expireTime=" + (m_qwNowTime + m_iSignValidDuration));        strContent += ("&random=" + m_iRandom);
        byte[] bytesSign = hash_hmac_byte(strContent, m_strSecKey);        byte[] byteContent = System.Text.Encoding.Default.GetBytes(strContent);        byte[] nCon = new byte[bytesSign.Length + byteContent.Length];        bytesSign.CopyTo(nCon, 0);        byteContent.CopyTo(nCon, bytesSign.Length);        return Convert.ToBase64String(nCon);    }}class Program{    static void Main(string[] args)    {        Signature sign = new Signature();        sign.m_strSecId = "个人 API 密钥中的 Secret Id";        sign.m_strSecKey = "个人 API 密钥中的 Secret Key";        sign.m_qwNowTime = Signature.GetIntTimeStamp();        sign.m_iRandom = new Random().Next(0, 1000000);        sign.m_iSignValidDuration = 3600 * 24 * 2;
        Console.WriteLine(sign.GetUploadSignature());    }}

#return str(signature2, 'UTF-8')
print("Original: ", Original)print("HMAC-SHA1: ", Sha1)print("Signature before BASE64: ", Signature)print("Signature after BASE64: ", str(Signature2))

Go 签名示例
