websocket致命错误消息:“无法监听tcp://0.0.0.0:8080:地址已在使用中”
我在尝试为我的网站创建一个websocket服务器时,遇到了一个致命错误,提示“无法在tcp://0.0.0.0:8080上监听:地址已在使用中”。我该如何解决这个问题呢?
问题是,我想在我的网站上设置一个websocket服务器,但收到了以下错误信息:“致命错误:未捕获的运行时异常:无法在“tcp://0.0.0.0:8080”上监听:地址已在使用中。”这个错误发生在TcpServer.php文件的第184行。我该如何排查和修复这个问题,以便成功在我的网站上设置websocket服务器呢?
我想实现管理员的Python程序和Python客户端之间通过PHP服务器实时发送数据。
这是管理员的Python脚本(发送方)
import asyncio
import websockets
import json
async def send_array():
uri = "ws://example.com:8080"
async with websockets.connect(uri, timeout=60.0) as websocket:
array_data = [1, 2, 3, "hello"]
await websocket.send(json.dumps(array_data))
asyncio.run(send_array())
当我运行它时出现的错误是
引发超时错误
这是PHP文件服务器
require_once 'vendor/autoload.php';
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class WebSocketServer implements MessageComponentInterface {
protected $clients;
public function __construct() {
$this->clients = new \SplObjectStorage;
}
public function onOpen(ConnectionInterface $conn) {
$this->clients->attach($conn);
echo "New connection! ({$conn->resourceId})\n";
}
public function onMessage(ConnectionInterface $from, $msg) {
$data = json_decode($msg, true);
if (is_array($data)) {
// Process the array data as needed
echo "Received array data: " . print_r($data, true) . "\n";
// Send the array data to all connected clients
foreach ($this->clients as $client) {
if ($from !== $client) {
$client->send(json_encode($data));
}
}
}
}
public function onClose(ConnectionInterface $conn) {
$this->clients->detach($conn);
echo "Connection {$conn->resourceId} has disconnected\n";
}
public function onError(ConnectionInterface $conn, \Exception $e) {
echo "An error has occurred: {$e->getMessage()}\n";
$conn->close();
}
}
PHP文件的错误是
致命错误信息,提示“无法在tcp://0.0.0.0:8080上监听:地址已在使用中”
这是Python客户端(接收方)
import asyncio
import json
import websockets
# Replace this URL with the URL of your PHP server
url = "ws://example:8080"
async def receive_array():
async with websockets.connect(url) as websocket:
while True:
# Receive data from the server
data = await websocket.recv()
array_data = json.loads(data)
# Print the received data for demonstration purposes
print("Received data: ", array_data)
# Run the real-time client
asyncio.get_event_loop().run_until_complete(receive_array())
asyncio.get_event_loop().run_forever()
我希望能得到一些指导,帮助我排查和解决在我的网站上设置websocket服务器时出现的“无法在tcp://0.0.0.0:8080上监听:地址已在使用中”的错误。我想实现管理员的Python程序和Python客户端之间通过PHP服务器实时发送数据。
