Support files as values to variables

No

Describe the solution you'd like

I'd like to be able to specify a value as a file location that automatically resolves and the content of the file gets put into the variable. E.g. jwt below would have the value of file:///Users/nl/work/data/jwt. This would facility not having to paste the JWT each time.

{
staging: {
baseUrl: "https://taskmanagement.cognosos.dev/api/v0",
jwt: "file:///Users/nl/work/data/jwt"
},
}

Thanks for the suggestion. I will consider adding this in the future.

Currently, there is no built-in function for reading files, but there is a workaround. Since the script runs on GraalVM JS, you can use Java classes. To read a file and assign its content to a variable, you can write the following in your pre-request script:

const Files = Java.type('java.nio.file.Files');
const Paths = Java.type('java.nio.file.Paths');

const path = Paths.get("path_to_your_jwt");

try {
    jc.variables.set("jwt", Files.readString(path));
} catch (e) {
    console.error("Error reading file: " + e.message);
}

You can then use the jwt variable wherever you need it.

Added the jc.readFile function to read file contents. You can now set a variable's value to the contents of a file using this script: jc.variables.set("jwt", jc.readFile('path')).

In the future, I plan to implement inline functions for variable values, like this: jwt: {{readFile('path')}}
