How to solve the problem that phpcms phpsso cannot exit synchronously? This problem may be often seen in our daily study or work. I hope you can gain a lot from this question. The following is the reference content that the editor brings to you, let's take a look at it!

What if phpcms cannot exit synchronously? Phpcmsv9 phpsso cannot exit synchronously?

Phpcmsv9 comes with a phpsso_server for simultaneous multi-site login and can integrate ucenter. In order not to change too much code, this phpsso is still used when integrating ECSHOP and PHPCMS today.

ECSHOP is very convenient and can communicate with ucenter with a simple configuration. This phpsso has been working for a long time but failed to communicate with ucenter. After hours of deliberation, they finally succeeded in getting them to communicate.

Registration, login, can all be synchronized, but when logging out in phpcms, ECSHOP does not quit, and vice versa.

The cause of the problem:

On the home page, you can see that there is a synchronous logout statement in the logout code of PHPCMS:

$synlogoutstr = $this- > client- > ps_member_synlogout ()

The synchronized logout code looks like this.

/ * * synchronous exit * @ param string $uid * @ return string javascript user synchronous exit js * / public function ps_member_synlogout () {return $this- > _ ps_send ("synlogout', array ());}

Notice that the second parameter to _ ps_send is an empty array.

Then see the constructor of the phpsso class in phpsso_server:

If (isset ($_ POST ["data'])) {parse_str (sys_auth ($_ POST ['data'],' DECODE', $this- > applist [$this- > appid] ['authkey']), $this- > data); if (emptyempty ($this- > data) |! is_array ($this- > data) {exit (' 0');}} else {exit ('0');}

Here is a judgment for $this- > data. If empty returns true, it will return 0 directly and the following synchronization exit code will not be executed. In the previous step, you can see that the data parameter passed in when calling synchronous logout is exactly array (), and empty will of course return true. So the invocation of synchronous exit ends here.

The solution to the problem:

Knowing the reason is easy to solve, there are two main kinds.

The safe way is to add a random element to the empty array in ps_member_synlogout.

The second is to remove the judgment of empty ($this- > data).
