使用 GatewayWorker + redis 使用出現(xiàn)問題

duoduo 更新于2016-11-25

使用 GatewayWorker + redis 使用出現(xiàn)問題，

我在 Events.php 中做如下處理

public static function onWorkerStart($businessWorker) 中初始化redis 

      $redis = new redis();
          $redis -> connect('127.0.0.1',6379);
          echo "啟動(dòng)redis\n";

public static function onMessage($client_id, $message) 中存儲(chǔ)數(shù)據(jù)

         $redis->zAdd($key, $i, $redis_str);

但是啟動(dòng)后，顯示如下錯(cuò)誤：

PHP Notice:  Undefined variable: redis in /GatewayWorker/Applications/YourApp/Events.php on line 149

Notice: Undefined variable: redis in /GatewayWorker/Applications/YourApp/Events.php on line 149
PHP Fatal error:  Call to a member function zAdd() on a non-object in /GatewayWorker/Applications/YourApp/Events.php on line 149

Fatal error: Call to a member function zAdd() on a non-object in /GatewayWorker/Applications/YourApp/Events.php on line 149
WORKER EXIT UNEXPECTED E_ERROR Call to a member function zAdd() on a non-object in /GatewayWorker/Applications/YourApp/Events.php on line 149
worker exit with status 65280
啟動(dòng)redis

不曉得是何原因哦，偶是新手，請(qǐng)各位大哥多多指點(diǎn)，感激不盡。

private $_redis;
public static function onWorkerStart($businessWorker) {
$redis = new redis();
$redis -> connect('127.0.0.1',6379);
$this->_redis=$redis;
echo "啟動(dòng)redis\n";
}

public static function onMessage($client_id, $message) {
$this->_redis->zAdd($key, $i, $redis_str);
}

@1424:您好，您這個(gè)也是有報(bào)錯(cuò)的。靜態(tài)方法中要用 self:: ，但是修改后也是有報(bào)錯(cuò)。郁悶了

其實(shí)把上面手冊(cè)那里基礎(chǔ)看懂就會(huì)了
