前提条件

开发要求

• 调用接口需要使用appId、accessKey和accessSecret密钥对进行接口认证签名
• appId、accessKey和accessSecret 需要由运营人员提供

认证信息

接口请求认证需要使用appId、accessKey和accessSecret对请求进行签名认证，设置请求头参数信息

签名算法

将appId、accessKey、accessSecret和timestamp按照以下顺序组合后，使用accessSecret作为密钥通过HmacSHA256加密输出作为signature值。

Java参考代码：

String appId = "e28af480a60f3234c0e9bb5a1d7c3780";
String accessKey = "c08578f98d9798c928053525de3d8650";
String accessSecret = "C475D7136B46ADFDC57B6BAF9A3BCCBB";
String timestamp = String.valueOf(System.currentTimeMillis());

String origin = appId+ "\n" + accessKey + "\n" + accessSecret + "\n" + timestampStr;
String signature = genSignature(accessSecret, origin);


public String genSignature(String secretKey, String data) {
    try {
        SecretKeySpec signingKey = new SecretKeySpec(secretKey.getBytes("UTF-8"), "HmacSHA256");
        Mac mac = Mac.getInstance("HmacSHA256");
        mac.init(signingKey);
        return Base64.getEncoder().encodeToString(mac.doFinal(data.getBytes("UTF-8")));
    } catch (NoSuchAlgorithmException | InvalidKeyException | UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    return null;
}

JavaScript参考代码：

var appId = "e28af480a60f3234c0e9bb5a1d7c3780";
var accessKey = "c08578f98d9798c928053525de3d8650";
var accessSecret = "C475D7136B46ADFDC57B6BAF9A3BCCBB";
var timestamp = Date.now(); // 当前时间戳

var origin = appId + "\n" + accessKey + "\n" + accessSecret + "\n" + timestamp;
var hash = CryptoJS.HmacSHA256(origin,accessSecret);
var signature = CryptoJS.enc.Base64.stringify(hash);
