Why there are duplicate api calls? #6

Closed xueenda closed 8 years ago

xueenda commented 8 years ago

I noticed for every api call there is a method "options" call first and then is the real api call. Why is that? How can I just make one "get" or "post" call?

random-quote OPTIONS 204 xhr build.js:15 258 B 5 ms
random-quote GET 200 xhr Other 292 B 5 ms
users/ OPTIONS 204 xhr build.js:15 272 B 5 ms
users/ POST 201 xhr Other 423 B 39 ms create/ OPTIONS 204 xhr build.js:15 272 B 4 ms
create/ POST 201 xhr Other 423 B 9 ms

You don't have to fix. That's the behaviour of cross origin http request.

When performing certain types of cross-domain Ajax requests, modern browsers that support CORS will insert an extra "preflight" request to determine whether they have permission to perform the action (reference)
