[视频教程] 最新版swoole安装和TASKS功能测试

今天我们来安装和测试一下php的多并发高性能网络通信扩展，这个扩展是使用c语音开发的，加载到php以后，在php的层面上实现了多并发异步通信，模拟了go语音的很多特性，极大的拓宽了php的应用场景。

直接使用官网上的那句命令就可以，安装swoole时可能会出现错误和卡住不动，多试几次就能成功。
pecl install swoole
要配置php的cli环境和fpm环境的ini文件，把扩展的so加载进去要红包。

视频地址：

httprver.php

$http = new swoole_http_rver("127.0.0.1", 9501);$http->on("start", function ($rver) {        echo "swoole http rver is started at http://127.0.0.1:9501\n";});$http->on("request", function ($request, $respon) {        $respon->header("content-type", "text/plain");            $respon->end("hello world\n");});$http->start();

注意使用httpclient的时候会有一些错误，首先新版的swoole移除了swoole\http\client,会报类找不到，其次要在协程中执行get方法

httpclient.php

$client = new swoole_client(swoole_sock_tcp, swoole_sock_async);$client->on("connect", function($cli) {    $cli->nd("hello world\n");});$client->on("receive", function($cli, $data){    echo "received: {$data}花粉的作用\n";});$client->on("error", function($cli){    echo "connect failed建党一百周年好句好段\n";});$client->on("clo", function($cli){    echo "connection clo\n";});$client->connect("127.0.0.1", 9502, 0.5);

taskrver.php

<?php$rv = new swoole\rver("127.0.0.1", 9502, swoole_ba);$rv->t(array(    'worker_num' => 2,    'task_worker_num' => 4,));$rv->on('receive', function(swoole\rver $rv, $fd, $from_id, $data) {    echo "接收数据" . $data . "\n";    $data = trim($data);    $task_id = $rv->task($data, 0);     $rv->nd($fd, "分发任务，任务id为$生命是什么task_id\n");});$rv->on('task', function (swoole\rver $rv, $task_id, $from_id, $data) {    echo "tasker进程接收到数据";    echo "#{$rv->worker_id}\tontask: [pid={$rv->worker_pid}]: task_id=$task_id, data_len=".strlen($data).".".php_eol;    $rv->finish($data);});$rv->on('finish', function (swoole\rver $rv, $task_id, $data) {    echo "task#$task_id finished, data_len=".strlen($data).php_eol;});$rv->on('workerstart', function($rv, $worker_id) {    global $argv;    if($worker_id >= $rv->tting['worker_num']) {        swoole_t_process_name("php {$argv[0]}: task_worker");    } el {        swoole_t_process_name("php {$argv[0]}: worker");    }});$rv->start();

taskclient.php

$client = new swoole_client(swoole_sock_tcp, swoole_sock_async);$client->on("connect", function($cli) {        $cli->nd("hello world\n");});$client->on("receive", function($cli, $data){        echo "received: {$data}\n";});$client->on("error", function($cli){  关于情人节的歌      echo "connect failed\n";});$client->on("clo", function($cli){        echo "connection clo\n";});$client->connect("127.0.0.1", 9502, 0.5);
