我正在尝试使用flask和请求模块开发一个小的小应用程序。我试图将一些数据发布到烧瓶Web应用程序中。但我坚持这个错误。
flask.py
@app.route('/add/', methods=['POST'])
def add_paths():
paths = request.form['paths']
tags = 'others'
for path in paths:
g.db.execute('insert into entries (path, tags) values(?, ?)',
[path, tags])
g.db.commit()
message = 'New paths are posted'
return jsonify(result = message)
用于发布数据的命令行文件
import json
import glob2
import requests
list = glob2.glob('/home/sheeshmohsin/*/**')
post_data = {'paths' : list }
headers = {'content-type': 'application/json'}
post_response = requests.post(url='http://localhost:9696/add/', data=json.dumps(post_data), headers=headers)
print post_response
print post_response.text
我得到的错误是: -
File "commandline.py", line 8, in <module>
post_response = requests.post(url='http://127.0.0.1:9696/add/', data=json.dumps(post_data), headers=headers)

resp = self.send(prep, **send_kwargs)
File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 438, in send
r = adapter.send(request, **kwargs)
File "/usr/lib/python2.7/site-packages/requests/adapters.py", line 327, in send
raise ConnectionError(e)
requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=9696): Max retries exceeded with url: /add/ (Caused by <class 'socket.error'>: [Errno 111] Connection refused)
答案 0 :(得分:0)
连接被拒绝错误消息表明它可能是您的防火墙或环回:
localhost
,以便Python不使用环回接口(requests.post(url='http://localhost:9696/add/',...
)。您可能必须对Flask(app..run(host='192.168...', port=9696)
)执行相同操作。
