guzzle/guzzle 日常使用

Guzzle

Guzzle 是一个 PHP HTTP 客户端，致力于让发送 HTTP 请求以及与 Web 服务进行交互变得简单。

Composer：https://packagist.org/packages/guzzlehttp/guzzle

发送请求

use GuzzleHttp\Client;

$client = new Client([
    //跟域名
    'base_uri' => 'http://localhost/test',
    // 超时
    'timeout'  => 2.0,
]);

$response = $client->get('/get'); //http://localhost/get
$response = $client->delete('delete');  //http://localhost/get/delete
$response = $client->head('http://localhost/get');
$response = $client->options('http://localhost/get');
$response = $client->patch('http://localhost/patch');
$response = $client->post('http://localhost/post');
$response = $client->put('http://localhost/put');

POST

$response = $client->request('POST', 'http://localhost/post', [
    'form_params' => [
        'username' => 'webben',
        'password' => '123456',
        'multiple' => [
            'row1' => 'hello'
        ]
    ]
]);

响应

# 状态码
$code = $response->getStatusCode(); // 200
$reason = $response->getReasonPhrase(); // OK

# header
// Check if a header exists.
if ($response->hasHeader('Content-Length')) {
    echo "It exists";
}

// Get a header from the response.
echo $response->getHeader('Content-Length');

// Get all of the response headers.
foreach ($response->getHeaders() as $name => $values) {
    echo $name . ': ' . implode(', ', $values) . "\r\n";
}

# 响应体
$body = $response->getBody();
// Implicitly cast the body to a string and echo it
echo $body;
// Explicitly cast the body to a string
$stringBody = (string) $body;
// Read 10 bytes from the body
$tenBytes = $body->read(10);
// Read the remaining contents of the body as a string
$remainingBytes = $body->getContents();

自定义header

// Set various headers on a request
$client->request('GET', '/get', [
	//header
    'headers' => [
        'User-Agent' => 'testing/1.0',
        'Accept'     => 'application/json',
        'X-Foo'      => ['Bar', 'Baz']
    ],
    //下载
	'save_to'=> $filename,
	//referer
	'allow_redirects' => [
		'referer'		=> '',
	],
]);

cookie 访问

$client = new \GuzzleHttp\Client();

$url = 'https://www.baidu.com/getUserInfo';

$jar = new \GuzzleHttp\Cookie\CookieJar();
$cookie_domain = 'www.baidu.com';
$cookies = [
	'BAIDUID' 	=> '221563C227ADC44DD942FD9E6D577EF2CD',
];

$cookieJar = $jar->fromArray($cookies, $cookie_domain);

$res = $client->request('GET', $url, [
       'cookies' => $cookieJar,
       // 'debug' => true,
]);
$body = $res->getBody();
