10. 響應樣本

{
 "success": true,
 "model": "28fdf560-249a-4712-adcc-906c0346602b",
 "errorCode": null,
 "errorMsg": null
}

11. 介面簽名

請求端需要對請求的內容進行簽名，服務端進行驗簽，以證明內容沒有被篡改，從而保障開發人員應用和開放平台互動的安全性。

11.1. 簽名涉及要素

11.1.1. Request URI

如請求地址為：https://{domainName}/openapi/v1/a/b

則requestURI為：/openapi/v1/a/b

11.1.2. Request Method

http請求的method。

11.1.3. Request Header

要求標頭主要包含以下幾個Fields（Field是大小寫敏感的）。

11.1.4. Request Body

Body為JSON格式的詳細請求資訊，其中的欄位因介面而異。

11.2. 簽名方式

1. 首先需要構造用於加簽的content，每次請求都會有以下屬性：

   • HTTP_URI : 例如 /openapi/v1/a/b

   • X-Access-Key：46b1cac78ed94ca4b99ad6de550a****

   • X-Request-Timestamp：1676904384074

   • HTTP_BODY : body 舉例如下：

{
	"appId": "223232323****",
	"authClientId": "7230000****,
	"grantType": "authorization_code",
	"authCode": "1cc19911172e4f8aaa509c8fb5d1****"
}

2. 基於以上資訊，{Content_To_Be_Signed}的格式如下，我們可以構造出需要加簽的content。<HTTP_METHOD> <HTTP_URI> <Client-Id>.<Request-Time>.<Access-Key>

POST /openapi/v1/a/b
{
	"appId": "223232323****",
	"authClientId": "7230000****",
	"grantType": "authorization_code",
	"authCode": "1cc19911172e4f8aaa509c8fb5d1****"
}.1676904384074.46b1cac78ed94ca4b99ad6de550afb68

3. 使用HmacSHA1演算法，以下的程式碼範例展示了如何加簽一個請求。

public String sign(String accessKey,String secretKey,String timestamp,String uri,byte[] bodyBytes) {
    String content = String.format("POST %s\n%s.%s.%s", uri, new String(bodyBytes), timestamp, accessKey);
    String signed = generateSign(content, secretKey, "HmacSHA1");
    return Base64.getEncoder().encodeToString(signed.getBytes(StandardCharsets.UTF_8));
}


public static String generateSign(String content, String key, String algorithm) {
    if (!StringUtils.isEmpty(algorithm) && !StringUtils.isEmpty(content) && null != key) {
        try {
            SecretKeySpec signinKey = new SecretKeySpec(key.getBytes(), algorithm);
            Mac mac = Mac.getInstance(algorithm);
            mac.init(signinKey);
            byte[] rawHmac = mac.doFinal(content.getBytes());
            return convertToHex(rawHmac);
        } catch (InvalidKeyException | NoSuchAlgorithmException var6) {
            return "";
        }
    } else {
        return "";
    }
}


public static String convertToHex(byte[] bytes) {
    int len = bytes.length;
    StringBuilder buf = new StringBuilder(len * 2);

    for(int j = 0; j < len; ++j) {
        buf.append(HEX[bytes[j] >> 4 & 15]);
        buf.append(HEX[bytes[j] & 15]);
    }

    return buf.toString();
}

11.3. 發送請求

通過將Client-Id、Request-Time和Signature添加到要求標頭，可以構造出如下請求：

curl -X POST \
  https://example.com/openapi/v1/a/b \
  -H 'Content-Type: application/json' \
  -H 'X-Access-Key: 46b1cac78ed94ca4b99ad6de550afb68' \
  -H 'X-Request-Timestamp: 1676904384074' \
  -H 'Signature: KrwDE9tAPJYBb4cUZU6ALJxGIZgwDXn5UkFPMip09n%2FkYKPhEIII%2Fki2rYY2lPtuKVgMNz%2BtuCU%2FjzRpohDbrOd8zYriiukpGAxBQDIVbatGI7WYOcc9YVQwdCR6ROuRQvr%2FD1AfdhHd6waAASu5Xugow9w1OW7Ti93LTd0tcyEWQYd2S7c3A73sHOJNYl8DC1PjasiBozZ%2FADgb7ONsqHo%2B8fKHsLygX9cuMkQYTGIRBQsvfgICnJhh%2BzXV8AQoecJBTrv6p%xxxx' \
  -d '{
	"appId": "223232323****",
	"authClientId": "7230000****",
	"grantType": "authorization_code",
	"authCode": "1cc19911172e4f8aaa509c8fb5d1****"
}'
