android - HttpUrlConnection.openConnection fails second time -

-

I know that this problem should be fixed with system .setProperty ("http.keepAlive", "false") ; Before OpenConnection, but he did not work before I try to work on this code, the second fails even if I try this request after less than 5 seconds, then it works . If I wait more than that, it fails again

This is my code: 

  System.setProperty ("http.keepAlive", "false" ); HttpURL Connection Conn = (HttpURLConnection) mURL.openConnection (); Conn.setUseCaches (wrong); Conn.setRequestProperty ("Connection", "Keep-Alive"); Conn.setRequestProperty ("user-agent", useragent); Conn.setConnectTimeout (30000); Conn.setDoOutput (right); Conn.setDoInput (true); Consumer.sign (Conn); Input source = new input source (conn.getInputStream ());

I get an exception on the last line: 

  java.io.IOException: Write error: I / O error during system call, broken pipe w / System.err (2164): on org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl: org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.nativewrite (Native method) w / System.err (2164 ) on .access $ 600 (OpenSSLSocketImpl.java:55) W / System.err (2164): org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl $ SSLOutputStream.write (OpenSSLSocketImpl.java:583) w / System. to err (2164): org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.sendRequest on (: java.io.OutputStream.write (OutputStream.java:82) W / System.err ( 2164) On HttpURLConnectionImpl.java:1332) W / System.err (2164): org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.doRequestInternal (HttpURLConnectionImpl.java:1656) W / System.err ( at 2164): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.doRequest (HttpURLConne ctionImpl.java:1649) W / System.err (2164): org.apache.harmony. luni.internal.net.www.protocol.http.HttpURLConnectionImpl.getInputStream (HttpURLConnectionImpl.java:1153) W / System.err (2164): org.apache.harmony.luni.internal.net.www.protocol.https. On HttpsURLConnectionImpl.getInputStream (HttpsURLConnectionImpl.java:253)

Is there an idea about what's wrong here? Thanks!

connection pool used by the HttpURL connection when this connection is alive It has broken so that it tries to use the connection closed by the server. By default, Android sets KeepAlive on all connections.

System.setProperty ("http.keepAlive", "false"); is a workaround that disables KeepAlive for all connections so that you avoid the bug in the connection pool.

conn.setRequestProperty ("Connection", "Keep-Elive"); Turns on KeepAlive for this special connection, essentially what is behind System.setProperty ("http.keepAlive", "false"); does.

In addition, I always explicitly call connect because it makes it clear that you are ending your connection setup. I'm not sure this method Calling is optional or not. 

  System.setProperty ("http.keepAlive", "false"); HttpURL Connection Conn = (HttpURLConnection) mURL.openConnection (); Conn.setUseCaches (wrong); Conn.setRequestProperty ("user-agent", useragent); Conn.setConnectTimeout (30000); Conn.setDoOutput (right); Conn.setDoInput (true); Consumer.sign (Conn); Conn.connect (); Input source = new input source (conn.getInputStream ());

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
