gateway 可以設(shè)置消息路由，手冊里有介紹

方法就是樓上說的為gateway設(shè)置路由，主要是 $key 的定制， 以下是路由至特定businessworker參考代碼：

$gateway->router = function($worker_connections, $client_connection, $cmd, $buffer){
    $target_businessworker = array(
        'ip'    => '127.0.0.1',          //填寫目標 businessworker ip
        'name'  => 'demoBusiness2',      //填寫目標 businessworker name
        'id'    => rand(0, 2),           //填寫目標 businessworker id
    );  

    $key = implode(':', array_values($target_businessworker));
    empty($client_connection->businessworker_address) && $client_connection->businessworker_address = $key;

    return $worker_connections[$client_connection->businessworker_addres];
};

謝謝兩位，看了好久的手冊都沒有，找到，謝謝！

用了樓上的代碼，不知道為什么報這個錯誤。

$gateway->router = function($worker_connections, $client_connection, $cmd, $buffer){
    $target_businessworker = array(
        'ip'    => '127.0.0.1',           //填寫目標 businessworker ip
        'name'  => 'BusinessWorker_Exchange',       //填寫目標 businessworker name
        'id'    => 0,  // rand(0, 1) ,            //填寫目標 businessworker id
    );

    $key = implode(':', array_values($target_businessworker));
     empty($client_connection->businessworker_address) && $client_connection->businessworker_address = $key;

    // var_dump( $worker_connections);
    return $worker_connections[$client_connection->businessworker_address];
};

二樓的代碼非常正確，只不過我的情況只有一個worker 所以ID 是0，然后我改成零不能用，后來var_dump發(fā)現(xiàn)沒有錯，經(jīng)檢查是因為0打了單引號。
初次寫代碼，不懂不好意思。
