解决Java call php web webService 中文参数乱码 终极解决方法

利用base64原理，在Java编写base64_encode函数，在php端解析，可以做到一劳永逸。

package com.webservices;
public class Base64_Encode { //对应php里的 base64_decode 方法    
        private static final String base64code = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
                        + "abcdefghijklmnopqrstuvwxyz" + "0123456789" + "+/";
        private static final int splitLinesAt = 76;
        public static byte[] zeroPad(int length, byte[] bytes) {
                // initialized to zero by JVM
        byte[] padded = new byte[length];
                System.arraycopy(bytes, 0, padded, 0, bytes.length);
                return padded;
        }
        public static String encode(String string) {
                String encoded = "";
                byte[] stringArray;
                try {
      // use appropriate encoding string!
                        stringArray = string.getBytes("UTF-8");    
                } catch (Exception ignored) {
      // use locale default rather than croak
                        stringArray = string.getBytes();    
                }
                // determine how many padding bytes to add to the output
                int paddingCount = (3 - (stringArray.length % 3)) % 3;
                // add any necessary padding to the input
                stringArray = zeroPad(stringArray.length + paddingCount, stringArray);
                // process 3 bytes at a time, churning out 4 output bytes
                // worry about CRLF insertions later
                for (int i = 0; i < stringArray.length; i += 3) {
                        int j = ((stringArray[i] & 0xff) << 16) +
                                ((stringArray[i + 1] & 0xff) << 8) +
                                (stringArray[i + 2] & 0xff);
                        encoded = encoded + base64code.charAt((j >> 18) & 0x3f) +
                                base64code.charAt((j >> 12) & 0x3f) +
                                base64code.charAt((j >> 6) & 0x3f) +
                                base64code.charAt(j & 0x3f);
                }
                // replace encoded padding nulls with "="
                return splitLines(encoded.substring(0, encoded.length() -
                        paddingCount) + "==".substring(0, paddingCount));

        }
        public static String splitLines(String string) {
                String lines = "";
                for (int i = 0; i < string.length(); i += splitLinesAt) {

                        lines += string.substring(i, Math.min(string.length(), i + splitLinesAt));
                        lines += "\r\n";
                }
                return lines;
        }
}
