范例

Example #1 EventHttpConnection::makeRequest() example

  <?php
 function  _request_handler ( $req ,  $base ) {
    echo  __FUNCTION__ ,  PHP_EOL ;

    if ( is_null ( $req )) {
        echo  "Timed out\n" ;
    } else {
         $response_code  =  $req -> getResponseCode ();

        if ( $response_code  ==  0 ) {
            echo  "Connection refused\n" ;
        } elseif ( $response_code  !=  200 ) {
            echo  "Unexpected response:  $response_code \n" ;
        } else {
            echo  "Success:  $response_code \n" ;
             $buf  =  $req -> getInputBuffer ();
            echo  "Body:\n" ;
            while ( $s  =  $buf -> readLine ( EventBuffer :: EOL_ANY )) {
                echo  $s ,  PHP_EOL ;
            }
        }
    }

     $base -> exit ( NULL );
}

 $address  =  "127.0.0.1" ;
 $port  =  80 ;

 $base  = new  EventBase ();
 $conn  = new  EventHttpConnection ( $base ,  NULL ,  $address ,  $port );
 $conn -> setTimeout ( 5 );
 $req  = new  EventHttpRequest ( "_request_handler" ,  $base );

 $req -> addHeader ( "Host" ,  $address ,  EventHttpRequest :: OUTPUT_HEADER );
 $req -> addHeader ( "Content-Length" ,  "0" ,  EventHttpRequest :: OUTPUT_HEADER );
 $conn -> makeRequest ( $req ,  EventHttpRequest :: CMD_GET ,  "/index.cphp" );

 $base -> loop ();
 ?>
