Java 代码中如何调用 第三方Api

参考：https://www.cnblogs.com/swordfall/p/10757499.html

在代码中，可能需要一个工具类，能够调用第三方API 获取一些数据

/**
     *  以 Get 方法调用API
     */
    public static void doGet(String pathUrl,String data) throws IOException{
        OutputStreamWriter  out = null;
        BufferedReader  br = null;
        String result =  "";
        try {
            URL url = new URL(pathUrl);
            //打开和 URL 之间的连接
            HttpURLConnection conn = (HttpURLConnection)url.openConnection();
            conn.setRequestMethod("GET");
            //设置通用属性
            conn.setRequestProperty("accept", "*/*");    
            InputStream is = (InputStream) conn.getInputStream();
            //构造一个字符缓冲流
            br = new BufferedReader(new InputStreamReader(is));
            String str = "";
            while((str=br.readLine())!=null) {
                result +=str;
            }
            System.out.println(result);
            //关闭流
            is.close();
            conn.disconnect();
            
        }catch(Exception e) {
            e.printStackTrace();
        }finally {
            try {
                if(out != null) {
                    out.close();
                }
                if(br != null) {
                    br.close();
                }
            }catch(IOException e) {
                e.printStackTrace();
            }
        }    
    }

测试类：

public class Main {
    public static void main(String[] args) throws Exception{
        MyHttpUrlConnection.doGet("https://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel=13026194071", "");
    }
}
