无法访问网络的问题
String path = "http://192.168.1.20:8080/BHHGYJ_web/aaa.jpg";//访问服务器上的一个图片
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//下断点跟踪发现conn的connected值是false，responseCode是-1
conn.setConnectTimeout(10000);
conn.setRequestMethod("GET");
if (conn.getResponseCode() == 200) {
InputStream inStream = conn.getInputStream();
return parseStream(inStream);
