OpenWeatherMap接口API

• 接口文档

当前天气查询接口

天气预报查询接口

• 接口特点

外国的这个接口，付费和收费的差别是接口的访问频率限制，获得的内容是一样的！我们现在这种测试项目程序，用这个接口非常合适。接口返回的信息中，也含有weather_code，并且也提供了相应的图标，但图标比较小，不够心知天气的图标漂亮，所以选择还是用心知天气的图标进行显 示，自己做一次weather_code的手工转码。

• Weather_code转码

天气代码定义文档

对应心知天气的code，自己写一个根据OWM天气代码返回心知天气代码的函数：

def convert_weather_code(argument):
    """Convert this API code to API_Thinkpage, so MainWindow can reuse the 
       pictures of API_Thinkpage.
    Args:
        A string of weather code, like '200'
    Returns:
        A string of weather code, like '16'
    """
    switcher = {
        #thunder
        '200': '16',
        '201': '16',
        '202': '16',
        '210': '16',
        '211': '16',
        '212': '16',
        '221': '16',
        '230': '16',
        '231': '16',
        '232': '16',

        #atomosphere

        '803': '7',
        '804': '4'
    }
    return switcher.get(argument, '99')

99为心知天气未知状态的图片，如果未查询到对应的代码，就返回“未知”状态。

• 读取天气信息，返回自定义参数

自己将返回信息定义得和心知天气API的格式一样，窗体可以用一样的代码读取，并放入对应的控件中。

def get_weather_now(city_input):
    """Get realtime weather info from http://api.thinkpage.cn/
    Args:
        city_input: The name of the city input by user.
    Returns:
        dict_weather_now:{
            "status_code": "200",
            "message": "ok",
            "name": city_name,
            "weather": "city_weather",
            "weather_code": "0",
            "temp": "city_temp"

    """Get weather forecast from http://api.thinkpage.cn/
