All submitted information is transmitted in the background. Users cannot see this process in the browser. High security. The

POST method is more suitable for sending confidential or large amounts of data to the server.

The GET method is the default method of the method attribute in the

form. Form data submitted using the GET method is appended to the URL and sent to the server as part of the URL.

Note: To send a form using the GET method, the length of the URL should be limited to 1MB characters. If the amount of data sent is too large, the data will be truncated, causing unexpected or failed processing results.

string urlencode(string str): URL-encode the string str

string urldecode(string str): Decode
