推荐答案

我碰巧使用worldweatheronline.com来获取当地天气.

他们的API的一部分包括城市搜索API-您给他们一个城市名称，然后它们会返回该名称的最佳匹配.例如，您给他们巴黎"，它会还给您:法国巴黎"，巴黎，德克萨斯州"等，以及每个人的纬度和经度.

如果您用谷歌搜索它们，还有其他可用的.

Google有一个类似的API，但是我对他们的使用条款的理解是，仅当您打算使用该API在地图上显示一个点时，才应该使用该API-因为那不是我使用的模型还有别的.

这里有一个很好的示例网页:

I happen to use worldweatheronline.com to get local weather.

Part of their API includes a city search API -- you give them a city name and they return the best matches for that name. For example you give them "Paris" it will give you back: "Paris, France", "Paris, TX" , etc. along with the latitude and longitude for each.

There are others available if you google for them.

Google has a similar API, but my understanding of their terms of use is you are only supposed to use that API if you are going to use it to display a point on a map -- since that isn''t my usage model I went with something else.

There''s a good sample webpage here:

http://stevemorse.org/jcal/latlon.php[^]

which I found via google. He lists links to services he uses to get the data, and you can also look at the source code for the page.
