Using Anonymous Structs in Go

This is just a short tutorial about using anonymous structs in Go, which can be very handy when dealing with JSON server responses (especially from Facebook).

So say you have this JSON response from the server:

Hidden Content

You must

[To see links please register here]

or

[To see links please register here]

to view this content.

and you want to put `lights` into a Go struct that looks like this:

Hidden Content

You must

[To see links please register here]

or

[To see links please register here]

to view this content.

with anonymous structs you can now do this with ease!

Hidden Content

You must

[To see links please register here]

or

[To see links please register here]

to view this content.

[To see links please register here]

is a link to a Go playground where I implemented this example.

Good luck with your Go coding!

That's interesting... So what exactly would creating an anonymous struct accomplish when dealing with server sent JSON repsonse(s)?

because you don't always want the outer JSON object, you just want the data portion. To do this without an anonymous struct you would have to define a new type like:

Hidden Content

You must

[To see links please register here]

or

[To see links please register here]

to view this content.

and then create an instance of that type and after you populate it with the response you have to extract the Lights map.

Facebook responses look like this:

Hidden Content

You must

[To see links please register here]

or

[To see links please register here]

to view this content.

and so I would make an anonymous struct to extract the data objects from the data tag, maybe like:

Hidden Content

You must

[To see links please register here]

or

[To see links please register here]

to view this content.

That's fucking dope dude. You're a legend.
