Use Google weather API to query weather forecasts

Use Google weather API to query weather forecasts

Google weather API only supports querying by zip code in the United States. For example:
Http://www.google.com/ig/api? Hl = ZH-CN & weather = 94043
(94043 is the zip code of Mountain View city, California, USA)

In addition to the United States, you must use latitude and longitude coordinates as parameters to execute the Google weather API. For example:
Http://www.google.com/ig/api? Hl = ZH-CN & weather =, 3067133, 104019996
(3067213,10409706 is the longitude and latitude coordinates of Chengdu and mainland China)

Of course, you may also query the city name in Chinese pinyin. For example, the following is the weather in Beijing.
Http://www.google.com/ig/api? Hl = ZH-CN & weather = Beijing

To coordinate the longitude and latitude of other regions, you can use the countries provided by Google APICodeYou can query the list and corresponding city longitude and latitude coordinates. The following are the query parameters provided by Google API:
Http://www.google.com/ig/countries? Output = xml & HL = ZH-CN

(Query the code of all countries supported by Google and display it in ZH-CN Simplified Chinese)
Http://www.google.com/ig/cities? Output = xml & HL = ZH-CN & Country = Cn
