An interface callback and the problem of receiving callback information

An interface callback and the problem of receiving callback information

This is the problem. When I interface with an agent, the user of the agent comes to me and the user logs in after successful verification.

The original design is

$url = 'http://www.1234.com/123.php?'.$PassportNotify;
$html = file_get_contents($url);

Then this $html returns a string re=0&msg=success

I ask the user to log in based on re=0 and refuse to log in if re=1


The problem now is that there may be a problem with the network communication between the servers, that is, the user is asked to log in regardless of re=0 or re=1
Then if re=1, it will send callback information to the other party's server until re=0 is received, which is somewhat similar to the asynchronousness of the Alipay interface

But I don’t know how to implement this method in the program. Thank you for your advice, thank you!

Let me answer

First of all, this call is inappropriate here. This is not called a callback
LZ go and see what is called a callback

In my opinion, it is the simplest while loop. Nothing difficult?

How to verify, GET or POST? For POST, file_get_contents alone cannot complete the task.

It is to send a complete URL address to the other party's server, and the other party's server will return a string. I accept this string to make a judgment. What is the best way to use this operation? I feel that it takes a long time to use file_get_contents. Is there any good way? Thank you

I just want to get a string from the other party's server address, and then get the return value. Is there any good way? Thank you!

for($count =1; $count++; $count
$html = file_get_contents($url);
parse_str($html);
print_r($re);

if($re == 0){
break;
}

Is this okay?

do {

$html = file_get_contents($url);

}while($html!=0);


Copy code

file_get_contents sends a URL to the other party's server and gets a response. It takes more than a minute to loop five times. It's so slow. Is there any other way?
