How to get the size of the request body of scripted rest API?

[Mahesh Bachhav]

I have scripted REST API in my ServiceNow scoped application. I would like to get the size of the request body when someone calls this REST API.

How to get the size of request body?

Hi,

what do you mean by size of request body?

It's not a file which can be measured in MB

Hey,

You can't really check the size of the payload

If you are looking to do some relevant details:

Property	Default value	Description
glide.rest.scripted.max_inbound_content_length_mb	10	The maximum size, in megabytes, for a scripted REST request body that is not gzipped.
glide.rest.scripted.max_inbound_gzip_content_length_mb	1	The maximum size, in megabytes, for a scripted REST request body that is gzipped.
glide.rest.max_content_length	10	The maximum size, in megabytes, for a scripted REST request body, whether or not it is gzipped. Maximum: 25 As a result, even if glide.rest.scripted.max_inbound_content_length_mb or glide.rest.scripted.max_inbound_gzip_content_length_mb are set, the request body is limited to the value of glide.rest.max_content_length.

Hi @Mahesh Bachhav 

It is not a file to get size.

If your body is in JSON format, you can get the length of the object. i.e, number of key-value pairs in that with below sample script.

let a = {
   name: "ABC",
   age: 100,
   country: "Singapore"
}
console.log(Object.keys(a).length)


//It will print 3 as output

Mark as correct or helpful if it works.

Regards,

Sumanth

As per Splunk documentation, the property "glide.rest.max_content_length" limits the maximum size, in megabytes, for a scripted REST request body.

Let me rephrase my question - 

I would like to get the content length of the request body in megabytes. The request body is in JSON and may have new line characters. How to do this?
