Nginx How to redirect a URL in Nginx?

For some reason this isn't working for me.

Code:

rewrite /register/facebook?reg=1 /register/connected-accounts/facebook/?setup=1 permanent;

But this one works fine:

Code:

rewrite /account/external-accounts /account/connected-accounts/ permanent;

---

 

This one works for me.

Code:

rewrite ^(/register/facebook*) /register/connected-accounts/facebook/?setup=1        permanent;
rewrite ^(/register/twitter*) /register/connected-accounts/twitter/?setup=1          permanent;

Don't know how to convert this into location block, as it's recommended than rewrite.

 

Works for me:

Code (Text):

location = /register/facebook  { return 301 https://site.com/register/connected-accounts/facebook/?setup=1; }
location = /register/twitter  { return 301 https://site.com/register/connected-accounts/twitter/?setup=1; }
location = /register/google  { return 301 https://site.com/register/connected-accounts/google/?setup=1; }
