问视频审核失败，总是返回空值， 状态显示 status: "PROCESSING" ？

@PostMapping("/describeVideoTask")

public Object DescribeVideoTask(

@RequestParam (name = "vodTaskId") String vodTaskId

) {

System.out.println("参数");

System.out.println(vodTaskId);

try{

Credential cred = new Credential("APPID", "SECRER");

HttpProfile httpProfile = new HttpProfile();

httpProfile.setEndpoint("ticm.tencentcloudapi.com");

ClientProfile clientProfile = new ClientProfile();

clientProfile.setHttpProfile(httpProfile);

TicmClient client = new TicmClient(cred, "ap-beijing", clientProfile);

String params = "{\"VodTaskId\":\""+vodTaskId+"\"}";

System.out.println(params);

DescribeVideoTaskRequest req = DescribeVideoTaskRequest.fromJsonString(params, DescribeVideoTaskRequest.class);

System.out.println(req);

DescribeVideoTaskResponse resp = client.DescribeVideoTask(req);

System.out.println(DescribeVideoTaskResponse.toJsonString(resp));

return resp;

} catch (TencentCloudSDKException e) {

System.out.println(e.toString());

}

return null;

}

加上变量就不行，返回空值，而且状态是 status: "PROCESSING"

String params = "{\"VodTaskId\":\""+vodTaskId+"\"}";

把vodTaskId写死就返回正常，求大神指点

String params = "{\"VodTaskId\":\"1254418846-procedurev2-5c4568825e168676014e5f23f03a20b4t0\"}";
