java 版 sdk 生成签名示例：

SignParams signParams = 

SignParams.builder().requestMethod("GET").uri("/api/customer/pageList").secretKey(secretKey).

headersAndParams(new HashMap<String, String>(){{

put("AccessKeyId", "JTQ9UtrjQg0XlPSINy0w");

put("SignatureMethod", "HMAC-SHA256");

put("SignatureVersion", "1.0");

put("Nonce", "8473822919405522134ED");

put("Timestamp", "2022-01-10T12:00:00Z");

put("ApiVersion", "2021-09-01");

put("RegionId", "cn-beijing");

put("RoleCode", " CecloudSystemRoleForAdministrator");

put("Host", "api.cecloudcs.com");

put("Content-Type", "application/json");

put("pageSize", "10");

put("curPage", "1");

}}).body("").build();

String signature = SignUtils.generateSignature(signParams);
