transcoding and decoding of URL parametersImport Java.net.URLDecoder; Import = "=abc%12= Urlencoder.encode (strtest, "UTF-8"= Urldecoder.decode ( Strtest, "UTF-8"); System.out.println (strtest);Execution Result:%3f%3dabc%3f%e4%b8%ad%251%262%3c3%2c4%3e=abc?%121. The problem arisesIn restful service design, when querying some information, the general URL address is designed as: Get/basic/service? Keyword= history, and the like URL address. However, in

Because of the project encountered in the server-side jar package program, to the foreground message, the previous paragraph received a message garbled situation, so take the message string before sending the message to ASCII code before sending to the foreground, The foreground takes a solution that turns the ASCII code into a string before receiving a background message.1) Java method for turning strings into ASCII Public Staticstring Stringtoascii (String value) {StringBuffer SBU=NewString

For this (class) issue:(1) The problem occurs when the unicodeencodeerror–> description is Unicode encoding;(2) ' GBK ' codec can ' t encode character–> description is an issue that occurs when encoding Unicode characters as GBK;At this point, it is often most likely that the character of the Unicode type itself contains some characters that cannot be converted to GBK encoding.The solution is: Scenario 1: When encoding Unicode characters, add the ignore parameter, ignoring characte

When using PHP json_encode to handle Chinese, Chinese will be encoded, become unreadable, similar to the "\u***" format, if you want Chinese characters do not transcode, here are three ways1. Upgrade PHP, in PHP5.4, the problem is finally resolved, JSON added an option: Json_unescaped_unicode, so the name Incredibles, that is, JSON do not encode UNICODE.1 PHP 2 3 Echo json_encode ("Chinese", json_unescaped_unicode); 4 5 // "Chinese"2. UrlEncode the Chinese characters first and then use the Json_

The principle is very simple, because the GB2312/GBK is Chinese two bytes, these two bytes is a range of values, and utf-8 Chinese characters are three bytes, also have a range of values for each byte. The English language is less than 128, regardless of the encoding, and occupies only one byte (except all corners). If it is a file-form code check, you can also check Utf-8 's BOM information directly. To say, directly on the function, this function is used to check the string and

If it's just a Unicode utf-8 encoded algorithm, the internet is everywhere, but a lot of people are you copy me, I copy you, do not understand why and do, in addition to the simplest PHP for Unicode transcoding utf-8 encoding functions, but also in-depth discussion of the two coding relationship, Understand that some of the old things on the internet, are seriously redundant and outdated, because from the beginning of the utf-8 popular to now, has bee

Today encountered a thorny problem, in the old project Riga some JS files and old project coding format inconsistencies appear garbled. The old page is GB2312, the link into the JS file is UTF-8, two files can not be transferred format. The first idea is to convert the Chinese in the JS file to Unicode encoding. This approach is based on the expense of readability of the conditions, the Chinese all become a password. Afterwards think that there should be a better way, and then go to Baidu, t

Example of jquery getting URL parameters and transcoding, jqueryurl Using jquery to obtain URL parameters and transcode them, I personally think it is good because sometimes garbled characters are not transcoded.Jquery obtains URL parameters and transcodes them. First, it constructs a regular expression object containing the target parameters, matches the target parameters, and returns the parameter values.Code: Test url: http://xxxx.html? Picture =
