Jenkins共享库：如何在groovy中创建一个函数，该函数接受字符串+映射并返回该映射值

Question

I am trying to create a shared library in Jenkins that will either take mapped arguments as a parameter, or if no arguments are provided will read from a config.yml file.

In order to do this I am trying to create a global function that checks if the provided parameter exists in a map of arguments:

getParam(String config_var, Map args) {
    return args.config_var
}

When I call this like so:

args = [
    test_var: "Hello World!"
]

echo getParam('test_var', args)

it returns null. However I change getParam() like so:

getParam(String config_var, Map args) {
    return args.test_var
}

calling it returns "Hello World!"

How can I change this function to dynamically return a value in the arguments passed into it?

更改以return args[config_var]
