POwrting byte array in java
text
Body
copied!<p>I'm trying to realize a Java server / c client and I have a problem with my put method in java. The server receive for example the array buffer. I printed in server what it received and it was = {-17 -65 -67 -17 -65 -67 -17 -65 -67 -17 -65 -67 0 16 74 70 73 70 0 1 1 0 0 1 0}. but when I write it with </p> <pre><code>FileOutputStream out = new FileOutputStream(filename); out.write(buffer); </code></pre> <p>And then I read the same file with </p> <pre><code>FileInputStream is = new FileInputStream(filename); is.read(buffer); </code></pre> <p>I don't get the same byte array. in this Example I get : buffer = {-17 -65 -67 -17 -65 -67 -17 -65 -67 -17 -65 -67 0 16 74 70 73 1 0 0 -1 -2 0 59 67}</p> <p><strong>EDIT :</strong> </p> <pre><code>private void put(String request, InputStream entreeSocket, OutputStream sortieSocket) { //request = "a/b/c/file.txt"; System.out.println(request); String[] s = request.split(" "); Path path = Paths.get(s[0]); String filename =""; int i = s[0].indexOf('/'); //System.out.println(request+i); if (i != -1){//System.out.println(request.substring(i)); filename = s[0].substring(s[0].lastIndexOf('/')+1); s[0] = s[0].substring(0,s[0].lastIndexOf('/')); path = Paths.get(s[0]); filename = path + "/"+filename; if (Files.notExists(path)){ if (!new File(s[0]).mkdirs()) return; } //System.out.println(path + " " + filename); } else filename = s[0]; i = request.indexOf("Content-Length"); //System.out.println(request.substring(i)); i = request.indexOf(":",i); //System.out.println(request.substring(i)); int j = request.indexOf("\r\n",i); int length = Integer.valueOf(request.substring(i+1,j).trim()); //System.out.print(length); byte[] buffer = new byte[2048]; j = request.indexOf("\r\n\r\n"); request = request.substring(j+4); System.out.print(length); //length = length - request.length(); try { buffer = request.getBytes("UTF-8"); print(buffer,buffer.length); length -= request.getBytes("UTF-8").length; FileOutputStream out = new FileOutputStream(filename); out.write(buffer, 0, request.getBytes("UTF-8").length); length = 0; while(length > 0){ int nb; if(length > buffer.length) nb = entreeSocket.read(buffer,0,buffer.length); else nb = entreeSocket.read(buffer,0,length); print(buffer,nb); out.write(buffer,0,nb); if(nb == -1) break; length -=nb; } sortieSocket.write(new String("205 OK\r\n").getBytes()); out.close(); entreeSocket.close(); sortieSocket.close(); FileInputStream is = new FileInputStream(filename); int nb = is.read(buffer); print(buffer,nb); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } </code></pre> <p>That the debut of my corrupt files:</p> <pre><code>ef bf bd 50-4e 47 0d 0a-1a 0a 00 00-00 0d 49 48 </code></pre> <p>That the debut of the original files</p> <pre><code>89 50 4e 47-0d 0a 1a 0a-00 00 00 0d-49 48 44 52 </code></pre>
