rasahttpapi测试

rasa - http api测试

rasa run --enable-api --cors "*"

仅解析意图

请求地址：localhost:5005/model/parse
命令行 curl -X POST localhost:5005/model/parse -d ‘{“text”: “hello”}’

代码示例

import json
import requests
url = "http://localhost:5005/model/parse"
data = {"text": "hello"}
data = json.dumps(data, ensure_ascii=False)
data = data.encode(encoding="utf-8")
r = requests.post(url=url, data=data)
print(json.loads(r.text))


连续对话

请求地址： localhost:5005/webhooks/rest/webhook
curl -X POST localhost:5005/webhooks/rest/webhook -d {“sender”: sender, “message”: message}

代码示例

import json
import secrets
import requests
def post(url, data=None):
data = json.dumps(data, ensure_ascii=False)
data = data.encode(encoding="utf-8")
r = requests.post(url=url, data=data)
r = json.loads(r.text)
return r
sender = secrets.token_urlsafe(16)
url = "http://localhost:5005/webhooks/rest/webhook"
while True:
message = input("Your input -> ")
data = {
"sender": sender,
"message": message
}
print(post(url, data))


1. post请求，添加messages

请求地址：localhost:5005/conversations/0/messages
命令行 curl -X POST localhost:5005/conversations/0/messages -d ‘{ “text”: “Hello!”, “sender”: “user” }’

2. post请求，预测action

请求地址：localhost:5005/conversations/0/predict
命令行 curl -X POST localhost:5005/conversations/0/predict

3. 执行action

请求地址：localhost:5005/conversations/0/execute
命令行 curl -X POST localhost:5005/conversations/0/execute -d ‘{ “name”: “utter_greet” }’

代码示例

import json
import requests
def post(url, data=None):
data = json.dumps(data, ensure_ascii=False)
data = data.encode(encoding="utf-8")
r = requests.post(url=url, data=data)
r = json.loads(r.text)
return r
if __name__ == "__main__":
# 会话id，此处简单设为0
conversation_id = 0

# 1. 发送消息
url = "http://localhost:5005/conversations/{}/messages".format(conversation_id)
data = {
"text": "Hi",
"sender": "user"
}
result = post(url, data)
print(result)
# 2. 预测下一步动作
url = "http://localhost:5005/conversations/{}/predict".format(conversation_id)
result = post(url)
print(result)
# 3. 执行动作
url = "http://localhost:5005/conversations/{}/execute".format(conversation_id)
data = {
"name": result["scores"][0]["action"] # 取置信度最高的动作
}
result = post(url, data)
print(result)
print(result["messages"]) # 获取对话信息
# [{'recipient_id': '1', 'text': 'Hey! How are you?'}]


对话流程

简单例子无法连续对话，如何连续对话呢？

import json
import secrets
import requests
def post(url, data=None):
data = json.dumps(data, ensure_ascii=False)
data = data.encode(encoding="utf-8")
r = requests.post(url=url, data=data)
r = json.loads(r.text)
return r
if __name__ == "__main__":
conversation_id = secrets.token_urlsafe(16) # 随机生成会话id
messages_url = "http://localhost:5005/conversations/{}/messages".format(conversation_id) # 发送消息
predict_url = "http://localhost:5005/conversations/{}/predict".format(conversation_id) # 预测下一步动作
execute_url = "http://localhost:5005/conversations/{}/execute".format(conversation_id) # 执行动作
action = "action_listen" # 动作初始化为等待输入
while True:
if action in ["action_listen", "action_default_fallback", "action_restart"]:
# 等待输入
text = input("Your input -> ")
post(messages_url, data={"text": text, "sender": "user"}) # 发送消息
respOnse= post(predict_url) # 预测下一步动作
action = response["scores"][0]["action"] # 取出置信度最高的下一步动作
respOnse= post(execute_url, data={"name": action}) # 执行动作
messages = response["messages"] # 取出对话信息
if messages:
print(messages)


domain.yml中的utter_great可添加buttons

responses:
utter_greet:
- text: Hey! How are you?
buttons:
- payload: '/mood_great'
title: 'great'
- payload: '/mood_unhappy'
title: 'sad'


常用命令

查看5005端口是否被占用 netstat -aon | findstr 5005
启动Rasa API服务（跨域）rasa run --enable-api --cors “*”
启动Rasa API服务（保存日志）rasa run --enable-api --log-file out.log
启动Rasa API服务（指定模型）rasa run --enable-api -m models

遇到的坑

若遇到死循环，一般是遇到默认动作没有退出，查看默认动作
