我在公司环境中使用，但在家庭环境中脚本可以正常工作

我正在尝试从一些天气网站获取响应。我编写了一个简单的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，会收到响应，但是在Python中却出现错误。 请帮忙。

完整的错误信息：

Traceback (most recent call last):
File "C:\Python34\weather.py", line 14, in <module>

File "C:\Python34\lib\urllib\request.py", line 153, in urlopen

Answer 1

您的代码按预期工作，除了响应字节应该进行解码，因为 json.loads 需要一个 str 对象。 更新 您需要像浏览器一样在 Python 代码中配置代理。您可以使用 urllib.request.Request.set_proxy 或者 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)

- falsetru

---

感谢您的快速回复。我已经将解码添加到脚本中，但是仍然出现相同的错误。我认为这个错误与我的环境有关：Win 7，Python 3.4.2，IDLE。 - Toren

@Toren，我刚刚在完全相同的环境中尝试了这段代码，它可以正常工作：http://i.imgur.com/Z9IHQaE.png - falsetru

你的代码在我的家庭环境下运行正常！不幸的是，在我的企业环境中仍然存在错误。也许我需要以某种方式包装代码？在企业环境中浏览器中相同的URL是正常的。 - Toren

根据配置，Internet Explorer 配置了代理脚本。 - Toren

@Toren，不用谢。我很高兴能对你有所帮助。我已经相应地更新了答案。 - falsetru

Answer 2

我会使用requests，使你的代码更简洁：

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)

为什么需要使用代理？是不是只有公共代理是免费的，所以我需要使用公共代理？ - MasayoMusic
