Yar_Concurrent_Client::loop

(PECL yar >= 1.0.0)

Yar_Concurrent_Client::loop — Send all calls

Descrizione

public static Yar_Concurrent_Client::loop(callable $callback = ?, callable $error_callback = ?): bool

Send all registed remote RPC calls.

Elenco dei parametri

callback

If this callback is set, then Yar will call this callback after all calls are sent and before any response return, with a $callinfo NULL.

Then, if user didn't specify callback when registering concurrent call, this callback will be used to handle response, otherwise, the callback specified while registering will be used.

error_callback

If this callback is set, then Yar will call this callback while error occurred.

Example #1 Yar_Concurrent_Client::loop() example

<?php
function callback($retval, $callinfo) {
     if ($callinfo == NULL) {
        echo "Now, all requests are sent, and no any response available\n";
     } else {
        echo "This is a remote call response, the method name is", $callinfo["method"], 
             ". calling sequence is " , $callinfo["sequence"] , "\n";
        var_dump($retval);
     }
} 

function error_callback($type, $error, $callinfo) {
    error_log($error);
}

Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"), "callback");
Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"));   // if the callback is not specificed, 
                                                                               // callback in loop will be used
Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"), "callback", NULL, array(YAR_OPT_PACKAGER => "json"));
                                                                               //this server accept json packager
Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"), "callback", NULL, array(YAR_OPT_TIMEOUT=>1));
                                                                               //custom timeout 

Yar_Concurrent_Client::loop("callback", "error_callback"); //send the requests, 
                                                           //the error_callback is optional
?>

Il precedente esempio visualizzerà qualcosa simile a:

Now, all requests are sent, and no any response available
This is a remote call response, the method name issome_method. calling sequence is 4
string(11) "some_method"
This is a remote call response, the method name issome_method. calling sequence is 1
string(11) "some_method"
This is a remote call response, the method name issome_method. calling sequence is 2
string(11) "some_method"
This is a remote call response, the method name issome_method. calling sequence is 3
string(11) "some_method"

loop是在所有的request请求都返回之后，才执行下一条吧？
而不是发出request之后立刻返回吧？
谢谢
