java爬淘寶第四級(jí)地址問(wèn)題

獲取淘寶街道地址，

請(qǐng)求的連接是：http://h5api.m.taobao.com/h5/...

    public String run(String link) {
        String data = "";
        try {
            // 建立連接
            URL url = new URL(link);
            HttpURLConnection httpUrlConn = (HttpURLConnection) url.openConnection();
            httpUrlConn.setDoInput(true);
            httpUrlConn.setRequestMethod("GET");
            httpUrlConn.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");
            // 獲取輸入流
            InputStream input = httpUrlConn.getInputStream();
            // 將字節(jié)輸入流轉(zhuǎn)換為字符輸入流
            InputStreamReader read = new InputStreamReader(input, "utf-8");
            // 為字符輸入流添加緩沖
            BufferedReader br = new BufferedReader(read);
            // 讀取返回結(jié)果
            data = br.readLine();
            while (data != null) {
                System.out.println(data);
                data = br.readLine();
            }
            // 釋放資源
            br.close();
            read.close();
            input.close();
            httpUrlConn.disconnect();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return data;
    }

就獲取不到了，有什么辦法沒(méi)
