天氣 API、Python 或 JavaScript

Question

我正在嘗試讓天氣 API 正常工作。 但是我如何才能獲得 C° 和天氣圖標； 沒有其他的？

Answer 1

使用 pip 安裝pywapi后，打開 ipython shell 並探索pywapi可以做什么。 這是一個實際上可以為您提供所需內容的示例：-

In [1]: import pywapi

In [2]: pywapi.
pywapi.GOOGLE_CITIES_URL                   pywapi.YAHOO_WEATHER_URL                   pywapi.get_weather_from_weather_com        pywapi.urlopen
pywapi.GOOGLE_COUNTRIES_URL                pywapi.getText                             pywapi.get_weather_from_yahoo              pywapi.wind_beaufort_scale
pywapi.NOAA_WEATHER_URL                    pywapi.get_cities_from_google              pywapi.minidom                             pywapi.wind_direction
pywapi.URLError                            pywapi.get_countries_from_google           pywapi.quote                               pywapi.xml_get_attrs
pywapi.WEATHER_COM_URL                     pywapi.get_everything_from_yahoo           pywapi.re                                  pywapi.xml_get_ns_yahoo_tag
pywapi.YAHOO_WEATHER_NS                    pywapi.get_weather_from_noaa               pywapi.sys                                 pywapi.yield_all_country_city_codes_yahoo

In [2]: pywapi.get_weather_from_yahoo?
Type:       function
String Form:<function get_weather_from_yahoo at 0x10daeb9b0>
File:       /Users/calvin/.virtualenvs/myweather/lib/python2.7/site-packages/pywapi.py
Definition: pywapi.get_weather_from_yahoo(location_id, units='metric')
Docstring:
Fetches weather report from Yahoo! Weather

Parameters:
  location_id: A five digit US zip code or location ID. To find your location ID,
  browse or search for your city from the Yahoo! Weather home page (http://weather.yahoo.com/)
  The weather ID is in the URL for the forecast page for that city. You can also get
  the location ID by entering your zip code on the home page. For example, if you
  search for Los Angeles on the Weather home page, the forecast page for that city
  is http://weather.yahoo.com/forecast/USCA0638.html. The location ID is USCA0638.

  units: type of units. 'metric' for metric and '' for non-metric
  Note that choosing metric units changes all the weather units to metric,
  for example, wind speed will be reported as kilometers per hour and
  barometric pressure as millibars.

Returns:
  weather_data: a dictionary of weather data that exists in XML feed.
  See http://developer.yahoo.com/weather/#channel

In [3]: pywapi.get_weather_from_yahoo('USCA0638')

正如您在結果中看到的，您可以在html_description ( http://l.yimg.com/a/i/us/we/52/33.gif ) 和temp獲得天氣圖標。 由於返回給您的結果就是一切，因此您需要像使用 Python 字典一樣提取/訪問它。

更新

1. 轉到http://weather.yahoo.com/並輸入您的郵政編碼（或您所在的城市）。
2. 如果選擇不止一種，請選擇您想要的一種。
3. 在“6-10 天”列下找到“擴展預測”鏈接。 點擊它。
4. 查看 URL 地址欄，那里的數字是您所在城市的郵政編碼。

所有城市代碼

這是幫助您獲取所有國家/地區、城市代碼的功能

In [4]: pywapi.yield_all_country_city_codes_yahoo?
Type:       function
String Form:<function yield_all_country_city_codes_yahoo at 0x10daebaa0>
File:       /Users/calvin/.virtualenvs/myweather/lib/python2.7/site-packages/pywapi.py
Definition: pywapi.yield_all_country_city_codes_yahoo(country_code, cities)
Docstring:
Yield all cities codes for a specific country.

Parameters:
  country_code: A four letter code of the necessary country. For example 'GMXX' or 'FRXX'.
  cities: The number of cities to yield

Returns:
  country_city_codes: A generator containing the city codes

Answer 2

您可以使用 Metwit天氣 api 。
如果您可以在客戶端實現它們：200 個請求/天（基於 ip 的限制）無需身份驗證。 全球覆蓋，符合 JSON 和 REST。 你可以免費注冊額外的 API 調用，如果你仍然需要它來調用它們服務器端，基本計划非常便宜。

這里有一個 jQuery 的小例子： http : //jsbin.com/isukam/1使用我們的天氣資源。

完全披露：我擁有這個甜蜜的 API。
