如何在Golang中访问另一个包的私有功能？

Question

I want to access a private function of a package called "pastry". But it generates error as: invalid reference to unexported identifier

Specify the way by which private functions of golang are accessible in main.

Answer 1

You can also add public proxy-function.

For example:

You have package-private function

func foo() int {
    return 42
}

You can create public function in the same package, which will call the package-private function and return it's result

func Bar() int {
    return foo()
}
