ModifyResponsePlugin， response with the Content-Type of application/json is

try {
String bodyStr = modifyBody(new String(responseBody,
StandardCharsets.UTF_8));
LOG.info("the body string {}", bodyStr);
return bodyStr.getBytes(StandardCharsets.UTF_8);
} catch (Exception e) {
LOG.error("modify response error", e);
throw new ShenyuException(String.format("response modify
failure. %s", e.getLocalizedMessage()));
