url - Java Load image from URLConnection -

-

मेरे पास URLConnection है, जो एक वेब पेज को एक्सेस करता है। 

  यूआरएल यूआरएल = नया यूआरएल ( "https: // डोमेन"); Con = url.openConnection (); con.setDoOutput (सही);

फिर मैंने con.setRequestProperty ()

का उपयोग करके सर्वर को कुछ डेटा भेजा है < / p> 

 <कोड> स्ट्रिंग headerValue = con.getHeaderField (6);

मुझे html भी मिलता है और वहां से एक छवि यूआरएल को पार्स करता है। लेकिन यहां एक समस्या है। मैं केवल, सर्वर को वापस कैश डेटा भेजने जब मैं मेरी छवि acces से इस छवि को मिल सकती है।

तो मैं एक नया कनेक्शन 

  यूआरएल URL1 = नए URL खोलने ( "Https: // domain / image); URLConnection con1 = url1.openConnection ();

मैं कुकीज़ को सर्वर पर वापस भेजता हूं con1.setRequestProperty (" cookie ", headerValue );

और अंत में मैं BufferedInputStream का उपयोग कर छवि को प्राप्त करने की कोशिश करता हूं और फिर एक जेलैबल में एक इमाज बना रहा हूं 

  BufferedInputStream = new BufferedInputStream (con1.getInputStream) ()); ByteArrayOutputStream byteArrayOut = नए ByteArrayOutputStream (); पूर्णांक ग, जबकि ((ग = in.read ()) = -1) {byteArrayOut.write (ग);}। छवि छवि = Toolkit.getDefaultToolkit () createImage (byteArrayOut.toByteArray ()); label.setIcon (नई ImageIcon (छवि));

समस्या यह काम नहीं लगता है यह एक और तरीका है एक सर्वर से एक फ़ाइल प्राप्त करने के लिए है। एक यूआरएल कनेक्शन के माध्यम से? आर कोड

<पूर्व> सर्वर ने यूआरएल के लिए एचटीएमपी प्रतिक्रिया कोड भेजा: 400: sun.net पर http://www.protocol.http.HttpURLConnection.getInputStream (अज्ञात स्रोत) पर https: // domain / image। net.www.protocol.https.HttpsURLConnectionImpl.getInputStream (अज्ञात स्रोत)

अग्रिम धन्यवाद

त्रुटि मिली मामला समाप्त। । कुकीज़ स्ट्रिंग विभाजित करने के लिए इस कोड को प्रयुक्त 

  स्ट्रिंग अस्थायी = headerValue.substring (0, (len1-17));

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).
