url codec
Encode and decode the URL component, and the data will not leave the browser.URL encoding description
URL component encoding and decoding
Convert texts such as query parameters, path fragments into safe percent codes, or restore encoded content to readable text.Component Code
Tools use URL component rules, encode characters such as slashes, question marks, and signs that may change the URL structure.
Chinese and spaces
Chinese will first convert to UTF-8 bytes and then encode; spaces are usually displayed as %20, not the plus sign in the form rules.
Avoid duplicate coding
Re-encoding the encoded percents will generate %25, and it should be confirmed that the input has been processed before use.

Use when content is to be used as a single query parameter value or path fragment, avoid the sabotage of the URL structure.
Why is decoding an error?
