URLEncode Encoding and Decoding
URLEncode encoding and decoding, convert the characters to be transcoded into hexadecimal, then take 4 bits from right to left (less than 4 bits are processed directly), make one bit every 2 bits, add% in front, and encode into% XY format. It is applicable to the encoding of uniform resource identifier (URI). It is also used to prepare data for "application / x-www-form-urlencoded" mime, and then submit HTML form data through HTTP request.
Calculate the MD5 hash value of the text, and the output result is expressed in HEX string and Base64 format. The input text will be converted into byte array using the selected character set, and then the MD5 hash value of the binary data will be calculated, and then the hash value will be expressed as HEX string and Base64 string.
WEBSOCKET Test Online
The websocket online test tool can be used as a websocket client to connect to the websocket server of the intranet or public network, and supports receiving and sending text messages in real time. Websocket is a new protocol under HTML5. It realizes the full duplex communication between browser and server, which can better save server resources and bandwidth, and achieve the purpose of real-time communication. Like HTTP, it transmits data through the established TCP connection, but its biggest difference from HTTP is that websocket is a two-way communication protocol. After the connection is established, the websocket server and client can actively send or receive data to each other, just like socket; Like TCP, websocket needs to establish a connection first. Only after the connection is successful can they communicate with each other.
User Agent Analysis Online
User agent online analysis. The Chinese name of user agent is user agent, abbreviated as UA. It is a special string header that enables the server to identify the operating system and version used by the customer, CPU type, browser and version, browser rendering engine, browser language, browser plug-in, etc.
HTML Color Picker
The HTML color picker selects the HTML color online and obtains the RGB value of the corresponding color. Supports transparency settings. This tool also provides common HTML color query and common HTML color name reference table query. HTML color is generally composed of red (R), green (g) and blue (b). Red, green and blue values (RGB) are usually represented by hexadecimal numbers. The lowest value of each color is 0 (hexadecimal 00) and the highest value is 255 (hexadecimal FF). Hexadecimal values are written as # numbers followed by three or six or eight hexadecimal characters. The three digit representation is: #rgb. The six digits are expressed as: #rrggbb. The eight digits are represented as #rrggbbaa, and the last two hexadecimal digits are alpha channel values, indicating the transparency of the color.
HTML Encode / Decode Online
HTML encoding and decoding tool, providing HTML entity online Decode and Encode functions. This tool supports encoding reserved characters in HTML into HTML character entities, and converting HTML character entities into corresponding characters.
JSON Format/JSON Parse Online
JSON Format/JSON Parse Online tool support online verification of JSON data format, formatting JSON data display, parsing JSON data, compressing JSON data and escaping JSON data. JSON data source supports inputting strings, opening local files and opening URLs.
Longitude Latitude Query and Positioning
Longitude Latitude Query and Positioning online:pick up the longitude and latitude coordinates through the online map, or query the longitude and latitude coordinates of the address. You can also reverse query the address information through the longitude and latitude coordinates.
CSS Selectors Reference
The CSS selector defines the range of elements that CSS rules apply to. This tool provides a reference manual for CSS universal selectors, type selectors, class selectors, id selectors, combination selectors, attribute selectors, pseudo class selectors, and so on. It also shows the CSS Level that this selector was introduced into.
Hash Calculation Online
Calculate the hash value of text and file online, and the calculation supports MD2, MD4, MD5, SHA1, SHA256, SHA384, SHA512, SHA3-224, SHA3-256, SHA3-384, SHA3-512 algorithms. The input data supports string, hex, base64 string or file. The hash value of the corresponding data is calculated, and the calculation result is expressed as hexadecimal string and base64 string.
