问为什么ChatBot在线测试结果和实际程序中获得结果不一样？

const tencentcloud = require("tencentcloud-sdk-nodejs");
const urlencode = require('urlencode');
class tencentBot {

    constructor() {

    }

    async getTencentBotResult(query) {
        const NlpClient = tencentcloud.nlp.v20190408.Client;
        const models = tencentcloud.nlp.v20190408.Models;

        const Credential = tencentcloud.common.Credential;
        const ClientProfile = tencentcloud.common.ClientProfile;
        const HttpProfile = tencentcloud.common.HttpProfile;

        let cred = new Credential(process.env.TencentAPIId, process.env.TencentAPIKey);
        let httpProfile = new HttpProfile();
        httpProfile.endpoint = "nlp.tencentcloudapi.com";
        let clientProfile = new ClientProfile();
        clientProfile.httpProfile = httpProfile;
        let client = new NlpClient(cred, "ap-guangzhou", clientProfile);

        let req = new models.ChatBotRequest();
        query = urlencode(query);
        let params = '{"Flag":0,"Query":' + '\"' + query + '\"}';
        //console.log(params);
        req.from_json_string(params);
        console.log(req);
        return new Promise((resolve) => {
            client.ChatBot(req, function (errMsg, response) {

            if (errMsg) {
                console.log(errMsg);
                resolve(null);
            }

            //console.log(response);
            resolve(response);
        });
        });
        
    }

}

module.exports.tencentBot = tencentBot;
