让服务器监听在另一个端口上运行的特定端口或Flask应用程序？

版本

rasa-core：0.9.0a3
rasa-nlu：0.12.3

Problema

我有一个web-app chat and a Rasa server这是一个聊天机器人，我希望聊天机器人处理从第一个收到的消息 .

在this tutorial结束时，可以读取路径是通过执行"run_server.bat"脚本启动以下命令来启动RASA-NLU服务器 . 加载自定义训练模型并开始侦听端口5000：

$ python -m rasa_nlu.server --path projects

我尝试了以下但终端告诉我端口已经在使用中

(myFlaskAppenv) mike@mike-thinks:~/Programing/Rasa/myflaskapp$ python -m rasa_nlu.server --path ~/Programing/Rasa/myflaskapp

确实 ：

(myFlaskAppenv) mike@mike-thinks:~/Programing/Rasa/myflaskapp$ python app.py 
 * Serving Flask app "app" (lazy loading)

   WARNING: Do not use the development server in a production environment.

所以，在我尝试与聊天机器人交谈的那一刻，它给了我在终端lou我把 app.py 包含所有路线：

127.0.0.1 - - [04/Jun/2018 16:42:46] "GET /parse?q=hi HTTP/1.1" 404 -
HOUSTON ! WE GOT AN EXCETPITON !
Expecting value: line 1 column 1 (char 0)
127.0.0.1 - - [04/Jun/2018 16:42:46] "POST /chat HTTP/1.1" 200 -

这是 app.py 的一部分，它指的是聊天机器人消息的处理，告诉我是否有更多需要，但我认为这不是最重要的：

@app.route('/chat',methods=["POST"])
def chat():
    try:
        user_message = request.form["text"]
        response = requests.get("http://localhost:5000/parse",params={"q":user_message})
        response = response.json()
        entities = response.get("entities")
        topresponse = response["topScoringIntent"]
        intent = topresponse.get("intent")
        print("Intent {}, Entities {}".format(intent,entities))
        if intent == "gst-info":
            response_text = gst_info(entities)# "Sorry will get answer soon" #get_event(entities["day"],entities["time"],entities["place"])
        elif intent == "gst-query":
            response_text = gst_query(entities)
        else:
            response_text = get_random_response(intent)
        return jsonify({"status":"success","response":response_text})
    except Exception as e:
        print("HOUSTON ! WE GOT AN EXCETPITON !")
        print(e)
        return jsonify({"status":"success","response":"Sorry I am not trained to do that yet..."})

So, what command should I make for the chatbot server to start listening and discussing with port 5000?
