测试天气查询API（JAVA版百度api、C#版APIX）未处理json

本文记录测试网络上免费的天气api，只测试两个。

百度一下有很多，可以自己去找别的。

例如我做测试的ＡＰＩＸ与ＡＰＩＳｔｏｒｅ。还有易源接口，聚合等等。。。。

首先给出百度ＡＰＩ的地址http://apistore.baidu.com/apiworks/servicedetail/112.html

测试根据城市名称查询天气的，另外还有历史７天与未来３天，根据城市拼音或者城市ｉｄ等其它接口不做测试

package com.lhh.Weather;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;


public class BaiduWeather {
	/*
	 * 根据城市名称查询天气
	 * @param city
	 * 
	 * auther 老辉辉
	 */
	
	//百度天气api上给的可用，免费apikey	d2ae44152f93b617584f9a6e8740c94e
	private static String mykey = "d2ae44152f93b617584f9a6e8740c94e";
	private static String httpUrl = "http://apis.baidu.com/apistore/weatherservice/cityname";
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String city = "福州";	
		String httpArg = "cityname="+city+"";
		String jsonResult = request(httpUrl, httpArg);
		System.out.println(jsonResult);
		
	}
	//向服务器发送请求，并传递参数
	public static String request(String httpUrl, String httpArg) {
	    BufferedReader reader = null;
	    String result = null;
	    StringBuffer sbf = new StringBuffer();
	    httpUrl = httpUrl + "?" + httpArg;

	    try {
	        URL url = new URL(httpUrl);
	        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
	        connection.setRequestMethod("GET");
	        connection.setRequestProperty("apikey",  mykey);
	        connection.connect();
	        InputStream is = connection.getInputStream();
	        reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
	        String strRead = null;
	        while ((strRead = reader.readLine()) != null) {
	            sbf.append(strRead);
	            sbf.append("
");
	        }
	        reader.close();
	        result = sbf.toString();
	    } catch (Exception e) {
	        e.printStackTrace();
	    }
	    return result;
	}
}
