Python Weather-API模块- Errno 11001: getaddrinfo失败错误

Question

最近，我又回到了我的一些代码，这些代码过去在weather api模块(https://pypi.org/project/weather-api/)中工作得很好。然而，现在它只是抛出了一个很长的错误，我不知道该如何处理。

我已经将错误追溯到weather.py，并尝试使用time.sleep()人为地降低请求速率，但是没有效果。

from weather import Weather , Unit
weather = Weather(unit=Unit.CELSIUS)
location = weather.lookup_by_location('London')

这将产生以下错误：

现在尝试解构Ln: 38处的D:\Program Files\Python\Lib\site-packages\weather\weather.py错误(在_call()函数中)，如下所示：

def _call(self, url):
    req = requests.get(url)
    print('here') # my addition to the code. This is never reached.
    if self.log:
        self.logger.info("Request URL: %s" % req.url)
        self.logger.info("Status Code: %s" % req.status_code)
        self.logger.info("JSON Response: %s" % req.content)
    if not req.ok:
        req.raise_for_status()

    try:
        results = req.json()
        if self.log:
            self.logger.info(results)
        if int(results['query']['count']) > 0:
            wo = WeatherObject(results['query']['results']['channel'])
            return wo
        else:
            if self.log:
                self.logger.warn("No results found: %s " % results)
            return
    except Exception as e:
        self.logger.warn(e)
        self.logger.warn(req.content)
        sys.exit(0)

我不知道为什么requests模块会导致这个错误，有谁知道解决方案吗？

预期结果:一个类对象，它应该包含来自雅虎天气的数据，可以用location.text将其读取为字符串。

实际结果:错误:/

Answer 1

雅虎的天气API被弃用了！谁能想到。

(意思是尝试在雅虎网址上运行requests.get(url)，但不再有效，没有得到正确的结果)
