发送CURL命令并从Flask页面检索响应

Question

当我启动此命令时：

$python -m rasa_core.server 
-d <DIALOGUE_MODEL_PATH> 
-u <NLU_MODEL_PATH> 
--debug 
-o out.log 
--cors *

当我使用curl -XPOST命令的终端时，我得到以下预期结果。

$ curl -XPOST localhost:5005/conversations/default/respond -d '{"query":"Hello"}'
[{"recipient_id": "default", "text": "Hello! How can I help?"}]

服务器似乎运行良好：

但是当我尝试通过图形界面发送消息时，我得到一个例外：

Expecting value: line 1 column 1 (char 0)
127.0.0.1 - - [06/Jun/2018 09:33:46] "POST /chat HTTP/1.1" 200

而这只来自Rasa服务器终端：

2018-06-06 09:41:14+0100 [-] "127.0.0.1" - - [06/Jun/2018:08:41:13 +0000] "GET /parse?q=Hi HTTP/1.1" 404 233 "-" "python-requests/2.18.4"

以下是app.py可能有问题的部分，我想：

@app.route('/chat',methods=["POST"])
def chat():
    try:
        user_message = request.form["text"]
        response = requests.get("http://localhost:5005/parse",params={"q":user_message})
        response = response.json()
        print("response :\n",response) 
        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:
            get_random_response = lambda intent:random.choice(intent_response_dict[intent])
            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..."})

**因此，我只是在Flask创建的图形页面上寻找使用CURL命令获得的相同答案。 **

目前我只得到：

Answer 1

你正在做一个get而不是post，它期望一个直接的字符串作为数据参数，而不是一个JSON对象作为param参数。我将我想解释的文本传递给这样的方法

   def apiai_text_request(self, text):
    request_text = '{"q":"'+text+'"}'
    result = requests.post("http://localhost:5000/parse", data = request_text)
    return result.json()
