Python请求在本地主机中返回504 [英] Python requests return 504 in localhost

问题描述

我运行 werkzeug 服务器(通过 Flask)并尝试通过请求库连接到本地主机并出现 504 错误，但如果打开 http://127.0.0.1:5000/ 在浏览器中 - 一切正常.

I run werkzeug server (via Flask) and trying to connect to localhost by requests lib and got 504 error, but if open http://127.0.0.1:5000/ in browser - anything ok.

我的代码:

import requests
r = requests.get('http://127.0.0.1:5000/')
print(r.content)

响应错误:

b'\r\n\r\n错误:网关超时\r\n

错误:网关超时

\r\n\r\n\r\n

尝试检索 URL http://127.0.0.1:5000/:

b'\r\n\r\nERROR: Gateway Timeout\r\n

ERROR: Gateway Timeout

\r\n\r\n\r\n

While trying to retrieve the URL http://127.0.0.1:5000/:

烧瓶代码:

from flask import Flask, request, render_template, jsonify, Response
import geoLocation
import models
import json
from bson.json_util import dumps
from bson import json_util



app = Flask(__name__)

@app.route('/', methods=['GET', 'POST'])
def index():
    return 'OK'
....

如何通过请求库连接到本地主机(ip + 端口)?

How to connect to localhost (ip + port) via requests lib?

推荐答案

找到解决方案，禁用代理

Found solution, disable proxy

import os
import requests

os.environ['NO_PROXY'] = '127.0.0.1'
r = requests.get('http://127.0.0.1:5000')
print(r.content)
