→ Enter the URL that contains the query string, for example: http://localhost:54176/api/ProductCategories?name=darren&age=25
→ Click the params, the query string is stored as a set of key-value teams
→ Select key-value pairs, right-select "encodeURIComponent" to encrypt keys or values


How to use body?

→form-data option, enter form data
→x-www-form-urlencoded options, enter form data, postman automatic encryption
→raw option, enter JSON data

{
"Name": "",
"Username": ""

}
→binary options, upload pictures, audio, video, etc.
