Commonly used encoding
The enctype attribute of form is the encoding method. There are two commonly used methods: application/x-www-form-urlencoded and multipart/form-data. The default is application/x-www-form-urlencoded.
1.x-www-form-urlencoded
When the action is get, the browser uses the x-www-form-urlencoded encoding method to convert the form data into a string (name1=value1&name2=value2...), then append the string to the url, split it with ?, and load it this new url.
2.multipart/form-data
When the action is post, the browser encapsulates the form data into the http body and sends it to the server. If there is no type=file control, use the default application/x-www-form-urlencoded. But if there is type=file, it is necessary to use multipart/form-data. The browser will divide the entire form in units of controls, and add Content-Disposition (form-data or file), Content-Type (default text/plain), name (control name) and other information to each part, and Add a delimiter (boundary).
