1、首先你需要注册聚合数据,获取相应的KEY

如图:

技术分享

 

2、得到相应的key后,我们就可以通过代码来获取数据了,具体代码如下:

/**
 * 获取菜谱数据
 */
public class CaiPumMenueActivity extends Activity {
    //配置您申请的KEY
    public static final String APPKEY = "82ca66***********49a93e5";
    String apiAddress = "http://apis.juhe.cn/cook/query?key=" + APPKEY +
            "&menu=午餐&rn=10&pn=3";

    /**
     * 请求菜谱数据
     * @param url:请求 用AsyncTask异步请求
     */
    public void readNet(String url)  //请求菜谱数据
    {
        new AsyncTask<String, String, String>() {
            StringBuilder sb;
            @Override
            protected String doInBackground(String... params) {
  try {
                        URL url = new URL(params[0]);
                        URLConnection connection = url.openConnection();      //建立连接
                        InputStream inputStream = connection.getInputStream();
                        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
                        BufferedReader br = new BufferedReader(inputStreamReader);
                        String line;
                        sb = new StringBuilder();
                        while ((line = br.readLine()) != null) {
                            sb.append(line);
                        }
                        br.close();
                        inputStream.close();
                        return sb.toString();

4、通过网络获取图片

  /**
     * //创建新的子线程
     * 获取图片
     */
    public void ImgThread(final String img) {
        new Thread() {
            private HttpURLConnection conn;
            private Bitmap bitmap;

            @Override
            public void run() {
                super.run();
                try {
                    URL url = new URL(img);
                    conn = (HttpURLConnection) url.openConnection();
                    conn.setConnectTimeout(5000);
                    conn.setRequestMethod("GET");
                    int code = conn.getResponseCode();
                    if (code == 200) {
                        InputStream is = conn.getInputStream();
                        bitmap = BitmapFactory.decodeStream(is);
                        Message msg = new Message();
                        msg.what = 1;
                        msg.obj = bitmap;
                        handler.sendMessage(msg);
                    } else {
                        Message msg = new Message();
                        msg.what = 2;
                        handler.sendMessage(msg);
                    }

                } catch (MalformedURLException e) {
                    Message msg = new Message();
                    msg.what = 2;
                    handler.sendMessage(msg);
                    e.printStackTrace();
                } catch (IOException e) {
                    Message msg = new Message();
                    msg.what = 2;
                    handler.sendMessage(msg);
                    e.printStackTrace();
                }
            }
        }.start();
    }
