大佬教程收集整理的这篇文章主要介绍了Android:java.net.protocolException不支持输出,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
public class MConnections { static String BaseURL = "http://www.xxxxxxxxx.com"; static String charset = "UTF-8"; private static String result; private static StringBuilder sb; private static List<String> cookies = new ArrayList<String>(); public static String PostData(String url,String sa[][]) { httpURLConnection connection = null; try { connection = (httpURLConnection) new URL(BaseURL + url) .openConnection(); } catch (MalformedURLException e1) { } catch (IOException e1) { } cookies = connection.getHeaderFields().get("Set-Cookie"); try{ connection.setDoOutput(true); // triggers POST. connection.setrequestProperty("Accept-Charset",charset); connection.setrequestProperty("Content-Type","application/x-www-form-urlencoded;charset=" + charset); }catch (Exception E) { //Here i get Exception that "java.lang.IllegalStateException: Already connected" } OutputStream output = null; String query = ""; int n = sa.length; for (int i = 0; i < n; i++) { try { query = query + sa[i][0] + "=" + URLEncoder.encode(sa[i][1],"UTF-8"); } catch (UnsupportedEncodingException E) { } } try { output = connection.getOutputStream(); output.write(query.getBytes(charset)); } catch (Exception E) { //Here i get Exception that "android: java.net.protocolException: Does not support output" } finally { if (output != null) try { output.close(); } catch (IOException E) { } } InputStream response = null; try { response = connection.geTinputStream(); } catch (IOException E) { //Here i get Exception that "java.io.IOException: BufferedInputStream is closed" } finally { //But i am closing it here connection.disconnect(); } try { BufferedReader reader = new BufferedReader(new InputStreamReader( response,"iso-8859-1"),8); sb = new StringBuilder(); sb.append(reader.readLine()); String line = "0"; while ((line = reader.readLine()) != null) { sb.append("\n" + linE); } response.close(); result = sb.toString(); } catch (Exception E) { } return result; } }
但是我在代码中注释了这样的异常.
其实我正在使用AsyncTask从我的Activity中@L_956_3@mConnections.PostData()两次.这可能会导致异常:已连接,但我正在使用COnnection.disconnect.但为什么我还会得到这个异常?
我用错了吗?
谢谢
