Question

我使用企业环境，在我家的环境中，脚本运行正常

我正试图从某个天气网站获得回复。我制作了一个简单的python脚本。

import urllib.request
import json

req=urllib.request.Request("http://api.wunderground.com/api/e0b319c6f7e8115a/geolookup/conditions/q/IA/Cedar_Rapids.json")
 response=urllib.request.urlopen(req)
 data = json.loads(response.read().decode())  #<--according to @falsetru fix
 print (data)

当我将URL粘贴到浏览器中时，我得到了响应，但在python中我收到错误 请帮忙

Answer 1

您的代码按预期工作，但响应字节应该被解码，因为json.loads需要str个对象。

<强>更新

您需要在Python代码中配置代理，例如浏览器。您可以使用urllib.request.Request.set_proxy或urllib.request.ProxyHandler：

import urllib.request
import json

req = urllib.request.Request("http://api.wunderground.com/api/e0b319c6f7e8115a/geolookup/conditions/q/IA/Cedar_Rapids.json")
req.set_proxy('PROXY_HOST:PROXY_PORT', 'http')  # <---
response = urllib.request.urlopen(req)
data = json.loads(response.read().decode())  # <----
print(data)

Answer 2

我会使用requests并使您的代码更简单：

import requests

proxies = {
"http": "http://ip:port",
"https": "http://ip:port",
}

req = requests.get("http://api.wunderground.com/api/e0b319c6f7e8115a/geolookup/conditions/q/IA/Cedar_Rapids.json",proxies=proxies)

data = req.json()
print(data)
