How to get the content type of the submitted data?
First, Content-Type is specified as application/x-www-form-urlencoded;Second, the submitted data is encoded as key1=val1&key2=val2, and both keys and Vals are URL transcoded.Most server-side languages support this approach very well.For example, $_in PHP POST ['title'] can get the value of title, $_POST ['sub'] can get a subarray.

Should I use application X-www-form-Urlencoded?
Hence, it is advised to use x-www-form-urlencoded when you have to send form data e.g. most of the web form which asks you to enter values and use multipart/form-data when you have to upload files to the server as used here.

To send an HTTP post request on form submission with a Content Type of multipart/form-data, one must explicitly specify this as the enctype value.
What is Urlencoded?
urlencoded() is a method inbuilt in express to recognize the incoming Request Object as strings or arrays. This method is called as a middleware in your application using the code: app.

Should I Urlencode POST data?
The general answer to your question is that it depends. And you get to decide by specifying what your "Content-Type" is in the HTTP headers. A value of "application/x-www-form-urlencoded" means that your POST body will need to be URL encoded just like a GET parameter string.
How does form data work?
FormData objects are used to capture HTML form and submit it using fetch or another network method. We can either create new FormData(form) from an HTML form, or create an object without a form at all, and then append fields with methods: formData. append(name, value)

Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
What is express JSON used for?
json() is a built-in middleware function in Express. This method is used to parse the incoming requests with JSON payloads and is based upon the bodyparser. This method returns the middleware that only parses JSON and only looks at the requests where the content-type header matches the type option.

summary
Two encoding formats for POST requests: application/x-www-urlencoded, which is the default encoding format for browsers, is used for key-value pair parameters with an interval between them;Multpart/form-data is commonly used for binary files, such as files, or for key-value pair parameters that are connected to a string of character transfers (refer to Java OK HTTP).In addition to these two encoding formats, application/json is also frequently used..
