In postman, the difference between form-data, x-www-form-urlencoded, raw, and binary is postmanbinary.

1. form-data:

IsMultipart/form-dataIt processes the form data as a message, and uses tags as the unit, separated by delimiters. You can upload key-value pairs or files. When the uploaded field is a file, Content-Type is used to indicate the file Type of the table name. content-disposition is used to describe some information about the field;

Because of boundary isolation, multipart/form-data can both upload files and key-value pairs. multipart/form-data adopts key-value pairs, so it can upload multiple files.

 

2. x-www-form-urlencoded:

YesApplication/x-www-from-urlencodedTo convert the data in the form to a key-value pair, for example, name = java & age = 23

 

3. raw

You can upload text in any format, text, json, xml, html, etc.

4. binary

EquivalentContent-Type: application/octet-streamOnly binary data can be uploaded, which is usually used to upload files. Because there is no key value, only one file can be uploaded at a time.
