The example of this article tells the way Java calls China Weather Network API to obtain weather forecast information. Share it for everyone for your reference. The specific implementation method is as follows:
// Take Bingcheng Harbin as an example to call the weather information through the Chinese weather API. ulthttpclient (); httpget httget = new httpget ("http: // m.weather.com.cn/data/101050101.html "); Responsehandler <string> Responsehandler = New Basicresponsehandler (); String Responsebody = httpclient.exec UTE (httget, responsehandler); System.out.println (responsebody); jsonparser JP = new jsonparser (); jsonelement jse = jp.parse (responsebody); jsonObject JSO = jse.getasjsonObject (). GetasjsonObject (); // raing updtime = jso.get ("fchh"). getasstring (); // if (updtime! = NULL) {// // Temperature // string j = jso.get ("temp1").
