- Uses curl for speed and reliability, not (trying to) re-inventing the wheel.
- Works with ajax calls that supports cookies
- Works (for me ) with a RESTful API including PUT and DELETE requests
- Works with nginx for php version below 5.4.0 where getallheaders aren't supported natively
- Works around the cross-domain request restrictions
- This script tries to do it's best to be a transparant medium
- Given the above, it does try to do it's best to send it's own http statuses in case of problems or missing required input without contacting a backend.
- Since it has cookie support, it should function for ajax-based logins accross domains
- crossproxy.php is the class
$proxy = new CrossProxy(array('http://live.tigerblood.com','dev/backend.php'));
CrossProxy class' constructor takes 4 arguments, only the first is required.
$forward_host, which is where all requests to the proxy will be routed. when this is an array, the second part will be added to the url (invisible to frontend calling the proxy) before calling the backend.
$allowed_hostname, which an optional parameter. Is this is supplied, it should be a hostname or ip address that you would like to restrict requests to. It can be an array of hostnames or IPs.
$handle_errors, which is a boolean flag with a default value of TRUE. If enabled, the object will use it's own error and exception handlers. handling in your application.
- array of optional options.
Another gotcha with cookies: Make sure that cookies being emitted from the target server are going to be accepted by the client. (cookie domain!)
- php curl !
Don't want to sound too negative, but I tried using others work but I didn't really like the way it was written, the one that came close was ajax-proxy by Kenny Katzgrau but that too did things not entirely correct. I tried to fork it and see if I could fix a few things here and there and i make it work for me, did some merging of a few upstreams but eventually I just wanted to rewrite it. I also didn't want to NOT use curl at all. This script is for people who have total control over their installs and can install curl at will. Another problem I had with other peoples code was not gracefully erroring out to the requester using http status codes. I did copy over some good idea's too and even code (including docs). Not all was bad.
