签名

我们建议您对webhoot推推送请求做签名校验，我们使用HmacSHA256 生成签名

请求webhoot API RequestHeader 可以获取签名字符串

header 'X-Mamba-hmac-sha256'

从Request.body获取JSON字符串，使用店铺密钥进行HmacSHA256计算得出签名，然后与X-Mamba-hmac-sha256签名对比即可

java示例代码

Java

    @PostMapping("/webHookCall")
    public ResponseEntity<String> webHookCall(HttpServletRequest request) {
        // 获取 request body 工具类根据实际情况选择
        String body = ServletUtil.getBody(request);
        String headerSign = request.getHeader("X-Mamba-hmac-sha256");

        if(StrUtil.isBlank(headerSign)) {
            // 签名为空直接返回失败
            return new ResponseEntity<>("fail", HttpStatus.UNAUTHORIZED);
        }
        String bodySign = HmacUtil.calculateHmac(body, "您的店铺密钥");

        if(!headerSign.equals(bodySign)) {
            // 签名校验不通过失败
            return new ResponseEntity<>("fail", HttpStatus.UNAUTHORIZED);
        }
        // 处理 业务
        ....
        return new ResponseEntity<>("success", HttpStatus.OK);
    }

Java

package com.mazentop.modules.api;

import org.apache.commons.codec.binary.Base64;

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.security.InvalidKeyException;

public class HmacUtil {

    public static final String HMAC_ALGORITHM = "HmacSHA256";
    public static String calculateHmac(String message, String secret) throws NoSuchAlgorithmException, InvalidKeyException {
        Mac hmac = Mac.getInstance(HMAC_ALGORITHM);
        SecretKeySpec key = new SecretKeySpec(secret.getBytes(), HMAC_ALGORITHM);
        hmac.init(key);
        return Base64.encodeBase64String(hmac.doFinal(message.getBytes()));
    }
}
