Question

I am using Net::HTTP to get a request from a Google API with a custom header:

req = Net::HTTP::Get.new(uri.request_uri, {'Authorization' => 'GoogleLogin auth=#{auth}'})

The #{auth} is a variable that changes each time I run the program, so I made a variable with it, but the single quotes don’t expand it. I can’t change the single quotes to double quotes, because Google only accepts the header with single quotes.

Is there any way to expand the variable but keep the single quotes?

Answer 1

However, I can’t change the single quotes to double quotes, because google only accepts the header with single quotes.

So hard to believe it.

Anyway, try Kernel%sprintf or its shorter version just str % [arguments..]. It will help.
