Python 3.x从URL获取JSON

Question

程序员大家好,

今天我想用Python 3.3从这个网站上获取一些JSON数据:http://ladv.de/api/-apikey-redacted-/ausDetail？id = 884&wettbewerbe = true&all = true

官方API告诉我,调用此URL会返回一些JSON数据.但是,如果我使用以下代码来获取它(我也在stackoverflow上找到它),它会抛出一个错误:

import urllib.request
import json

request = 'http://ladv.de/api/mmetzger/ausDetail?id=884&wettbewerbe=true&all=true'
response = urllib.request.urlopen(request)
obj = json.load(response)
str_response = response.readall().decode('utf-8')
obj = json.loads(str_response)
print(obj)

打印出来

Traceback (most recent call last):
  File "D:/ladvclient/testscrape.py", line 5, in <module>
    response = urllib.request.urlopen(request)
  File "C:\Python33\lib\urllib\request.py", line 156, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Python33\lib\urllib\request.py", line 475, in open
    response = meth(req, response)
  File "C:\Python33\lib\urllib\request.py", line 587, in http_response
    'http', request, response, code, msg, hdrs)
  File "C:\Python33\lib\urllib\request.py", line 513, in error
    return self._call_chain(*args)
  File "C:\Python33\lib\urllib\request.py", line 447, in _call_chain
    result = func(*args)
  File "C:\Python33\lib\urllib\request.py", line 595, in http_error_default
        raise HTTPError(req.full_url, code, msg, hdrs, fp)
    urllib.error.HTTPError: HTTP Error 404: Not Found

错误在哪里,什么是正确的代码？提前致谢,

您尝试获取的网站不可用,如下所示:

http://ladv.de/api/-apikey-redacted-/ausDetail?id=884&wettbewerbe=true&all=true

您也可以自己阅读错误消息:

urllib.error.HTTPError: HTTP Error 404: Not Found
