Ich verwende Verschlüsselung in Java und Entschlüsselung in PHP. Jetzt, wenn ich verschlüsselte Parameter an die URL übergeben habe, bekomme ich nicht die richtige Antwort. Hier ist mein Android-Code.

<code>public static InputStream multipartPOST(String urlStr, 
            Hashtable<String, String> stringParams, 
            Hashtable<String, File> fileParams) throws Exception {URL connectURL = new URL(urlStr);

            conn = (HttpURLConnection)connectURL.openConnection();
            conn.setDoInput(true);
            conn.setDoOutput(true);
            conn.setUseCaches(false);
            //conn.setChunkedStreamingMode(1000*1024);
            int timeout = 10000; 
            conn.setConnectTimeout(timeout);
            conn.setReadTimeout(timeout);
            conn.setRequestMethod("POST");
            conn.setRequestProperty("User-Agent", "RRE");
            conn.setRequestProperty("Connection","Keep-Alive");
            conn.setRequestProperty("Content-Type","multipart/form-data;boundary="+boundary);
            conn.setRequestProperty("Accept-Encoding","gzip");
            conn.connect();

            MessageDigest digester = MessageDigest.getInstance("MD5");
            digester.update(Constants.SALT1.getBytes());

            DataOutputStream dataStream = new DataOutputStream(conn.getOutputStream());
            //DataOutputStream dataStream =new DataOutputStream(new BufferedOutputStream(conn.getOutputStream(), 128000));


            ArrayList<String> stringParamsKeys = Collections.list(stringParams.keys());
            Collections.sort(stringParamsKeys);
            for (String stringParamsKey : stringParamsKeys) {
                String stringParamsValue = stringParams.get(stringParamsKey);
                if(stringParamsValue != null) {
                    writeFormField(dataStream, stringParamsKey, stringParamsValue, digester);
                }
            }

            if(fileParams != null) {
                ArrayList<String> fileParamsKeys = Collections.list(fileParams.keys());
                Collections.sort(fileParamsKeys);
                for (String fileParamsKey : fileParamsKeys) {
                    File fileParamsValue = fileParams.get(fileParamsKey);

                    FileInputStream fileInputStream = new FileInputStream(fileParamsValue);
                    BufferedInputStream bufferedInputStream = new BufferedInputStream(fileInputStream);

                    writeFileField(dataStream, fileParamsKey, fileParamsValue.getName(), "", bufferedInputStream, 
                            fileParamsValue.length(), digester);

                    // final closing boundary line
                    dataStream.writeBytes(twoHyphens + boundary + twoHyphens + CRLF);           
                    bufferedInputStream.close();
                    fileInputStream.close();
                }
            }
            System.out.println(dataStream);
            byte[] messageDigest = digester.digest();
            String md5Hash = Utils.byteArrayToHexString(messageDigest);
            writeFormField(dataStream, "md5Hash", md5Hash, null);

            dataStream.flush();
            dataStream.close();
            dataStream = null;
            try
            {
                InputStream in=conn.getInputStream();

            }
            catch (Exception e) {
                // TODO: handle exception
                Log.d("logexception",e.toString());
            }
            InputStream inputStream = conn.getInputStream();
            System.out.println(inputStream);
            try
            {
                 String contentEncoding = conn.getContentEncoding();
                 Log.d("logexceptio",contentEncoding.toString());
            }
            catch (Exception e) {
                // TODO: handle exception
                Log.d("logexceptionhhhhhhhh",e.toString());
            }
            Log.d("loghi","hiiiiii");
            String contentEncoding = conn.getContentEncoding();

            if (contentEncoding != null && contentEncoding.equalsIgnoreCase("gzip")) {
                System.out.println("gggzzziiippppppp");
                inputStream = new GZIPInputStream(inputStream);
            }

            return inputStream;
            }

In stingParams habe ich verschlüsselte Parameter übergeben. Ich habe eine Ausnahme bei conn.getinputstream (). Wenn ich die verschlüsselte URL im Browser übergeben, läuft es gut. aber von der android seite habe ich die ausnahme bekommen. Kannst du mir bitte sagen, was ich falsch mache?
