OpenSwoole\Coroutine\Http\Client::__construct(...)

Description

Create a new HTTP Client within a co::run coroutine context.

When specifying the host you can add the protocol of the host like http:// or https://. There is also support for Unix Sockets like unix://tmp/your_file.sock.

Note: HTTPS support is only available if OpenSwoole was compiled with SSL support.

Structure

The structure of the HTTP Client object before execution of any requests:

<?php

var_dump(new OpenSwoole\Coroutine\Http\Client('swoole.co.uk', 443, true));

...

object(OpenSwoole\Coroutine\Http\Client)#3 (18) {
  ["errCode"]=>
  int(0)
  ["errMsg"]=>
  string(0) ""
  ["connected"]=>
  bool(false)
  ["host"]=>
  string(12) "swoole.co.uk"
  ["port"]=>
  int(443)
  ["ssl"]=>
  bool(true)
  ["setting"]=>
  NULL
  ["requestMethod"]=>
  NULL
  ["requestHeaders"]=>
  NULL
  ["requestBody"]=>
  NULL
  ["uploadFiles"]=>
  NULL
  ["downloadFile"]=>
  NULL
  ["downloadOffset"]=>
  int(0)
  ["statusCode"]=>
  int(0)
  ["headers"]=>
  NULL
  ["set_cookie_headers"]=>
  NULL
  ["cookies"]=>
  NULL
  ["body"]=>
  string(0) ""
}

Example

Using a parsed URL host (domain name) and path

<?php
use OpenSwoole\Coroutine\HTTP\Client;

co::run(function()
{
  $urlInfo = parse_url('https://swoole.co.uk');

  $host = $urlInfo['host'];
  $path = $urlInfo['path'];

  $client = new Client($host);

  $client->setHeaders([
      'Host' => $host,
      "User-Agent" => 'Chrome/49.0.2587.3',
      'Accept' => 'text/html,application/xhtml+xml,application/xml',
      'Accept-Encoding' => 'gzip',
  ]);

  $client->set(['timeout' => 1]);

  $client->get($path);

  echo $client->body;

  $client->close();
});

Using a direct IP and Port

<?php

use OpenSwoole\Coroutine\Http\Client;

co::run(function()
{
  $client = new Client('127.0.0.1', 80);

  $client->setHeaders([
      'Host' => 'localhost',
      'User-Agent' => 'Chrome/49.0.2587.3',
      'Accept' => 'text/html,application/xhtml+xml,application/xml',
      'Accept-Encoding' => 'gzip',
  ]);

  $client->set(['timeout' => 1]);

  $client->get('/index.php');

  echo $client->body;

  $client->close();
});
