瀏覽器地址欄字符串轉化

將地址欄中傳發送請求時,中文和一些特殊字符轉化成%12的字符串轉換回來。

String str = "value1=%7B%22actorType%22%3A%22{ACTOR_TYPE}%22%2C%22actorId%22%3A%22{HPP_USER_ID}";
        //String str = "%E4%BD%A0%E5%A5";
        StringBuffer stringBufferResult = new StringBuffer();
        for (int i = 0; i < str.length(); i++)
        {
            char chr = str.charAt(i);
            if (chr == '%')
            {
                StringBuffer stringTmp = new StringBuffer();
                stringTmp.append(str.charAt(i + 1)).append(str.charAt(i + 2));
                //轉換字符，16進制轉換成整型
                stringBufferResult.append((char)(Integer.valueOf(stringTmp.toString(), 16).intValue()));
                i = i + 2;
                continue;
            }
            stringBufferResult.append(chr);
        }

        System.out.println(stringBufferResult);
        String newStr = new String(stringBufferResult.toString().getBytes("Cp1252"), "UTF-8"); //編碼轉換
        System.out.println(newStr);
