java调用接口的get方法

 //接口调用
    public String get(String httpUrl) { // httpurl为所调用接口的url
        String result = "";
        try {
            URL url = new URL(httpUrl.toString());
            StringBuffer document = new StringBuffer();
            HttpURLConnection httpconn = (HttpURLConnection) url.openConnection();
            httpconn.setRequestProperty("accept", "*/*");
            httpconn.setRequestProperty("connection", "Keep-Alive");
            httpconn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");
//建立实际的连接
            httpconn.connect();
            InputStream input = null;
            try {
                httpconn.connect();
                input = httpconn.getInputStream();
            } catch (Exception e) {
                e.printStackTrace();
            }
            BufferedReader reader = new BufferedReader(new InputStreamReader(input));
            String Result = "";
            while ((Result = reader.readLine()) != null) {
                document.append(Result);
            }
            result = document.toString();

        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }
