请问使用CommonRequest调用集群的接口时，RequestBody具体的格式内容是？

我看到你们demo都是get请求的，put请求的怎么使用，我这里调用都是无效的

public String k8sScaleCluster(String regionId) {

    CommonRequest request = new CommonRequest();

    request.setMethod(MethodType.PUT);

    request.setDomain("cs.aliyuncs.com");

    request.setVersion("2015-12-15");

    request.setUriPattern("/clusters/1222222222222222222221");
    request.putQueryParameter("RegionId", regionId);
    request.putHeadParameter("Content-Type", "application/json");


    String requestBody = "" +
            "\"key_pair\":\"test\"," +
            "\"worker_data_disk\":false," +
            "\"worker_system_disk_category\":\"cloud_efficiency\"," +
            "\"worker_system_disk_size\":120," +
            "\"worker_instance_types\":[\"ecs.hfg5.2xlarge\",\"ecs.hfg5.large\"]," +
            "\"vswitch_ids\":[\"vsw-steststtessss\"]," +
            "\"count\":1";
    request.setHttpContent(requestBody.getBytes(), "utf-8", FormatType.JSON);
    CommonResponse response = null;
    try {
        response = client.getClient(regionId).getCommonResponse(request);
        System.out.println(response.getData());
    } catch (ServerException e) {
        e.printStackTrace();
    } catch (ClientException e) {
        System.out.println("==========:" + e.getErrCode());
        e.printStackTrace();
    }
    return response.getData();
}

报错内容如下： ==========:SDK.UnknownError com.aliyuncs.exceptions.ClientException: SDK.UnknownError : code=400, message=Unmarshal type error: expected=types.CreationRequest, got=string, offset=10
