无聊整理的真正免费的天气API，无需注册申请key等，当然部分数据解析需要自己理解下，也不是所有天气数据都有，如果有特别需求，还是使用各个收费的天气供应商支持。这仅分享各开发者学习测试使用。
1.中华万年历的天气API
url:http://wthrcdn.etouch.cn/WeatherApi?city=城市名 或 http://wthrcdn.etouch.cn/WeatherApi?citykey=城市代码，平常使用觉得直接传对应城市名更方便些，citykey还需要查找。
返回的数据是XML格式，
1.支持的数据当时温度、湿度、风力、风向、日出时间、日落时间；
2.支持前一天和未来五天的数据，包含高-低温，白天天气和夜晚天气；
3.支持一些天气指数提示和建议，包括穿衣指数，紫外线指数，运动指数等；
例如，查询上海的天气
http://wthrcdn.etouch.cn/WeatherApi?city=上海
返回结果：

2.讯飞语音识别内置的墨迹天气API
url:http://autodev.openspeech.cn/csp/api/v2.1/weather?openId=aiuicus&clientType=android&sign=android&city=上海&latitude=39.902895&longitude=116.427915&needMoreData=true&pageNo=1&pageSize=7
支持通过城市名直接查询或者通过经纬度查询，city和经纬度经过一种方式即可。
注意：url中的openId、clientType以及sign等参数具体含义我也不清楚，但写此文档时如上参数是必需的，否则请求失败；具体传什么值好像并没影响。
返回数据为json格式；支持未来7天的数据查询，支持的数据有天气、温度、湿度、PM2.5、PM10、空气指数、空气质量、日出时间、日落时间等；
例如查询上海数据：http://autodev.openspeech.cn/csp/api/v2.1/weather?openId=aiuicus&clientType=android&sign=android&city=上海&needMoreData=true&pageNo=1&pageSize=7

以上即是两个免费的天气API介绍。第一个中华万年历的应该更稳定些，第二个是讯飞内置的语音查询天气API，不排除后续讯飞接口优化。
3.乐享天气APP
潇潇已经使用中华万年历API开发了一款天气APP，有兴趣的朋友可参看。
