Guzzle 介绍
Guzzle 是一款简单、易用的 PHP HTTP 客户端。
它可以快速的集成到 WEB 项目中,帮助我们非常方便的发送 HTTP 请求。
Guzzle 特点
接口简单
支持使用 curl,PHP streams,sockets等各种方式。
支持同步和异步请求
遵循 PSR7 规范,可以集成其他的符合 psr7 规范的类库,自定义处理逻辑
安装
使用 composer 安装,非常方便
composer require --prefer-dist guzzlehttp/guzzle
快速入门
1.初始化客户端
use GuzzleHttp\Client;
options = [
'base_uri' => 'http://guzzle.testhttp.com',
'connect_timeout' => 1,
'timeout' => 3,
];
$client = new Client($options);
2.发送body请求
$client->request('POST', '/post', ['body' => 'this is post body']);
3.发送表单请求
$client->request('POST', '/post', [
'form_params' => [
'user_id' => 1,
'user_name' => 'hello world!'
]
]);
4.json 请求
$client->request('POST', '/post', ['json' => ['data' => 'hello world!']]);
5.使用cookie
$params = ['json' => ['data' => 'hello world!']];
$cookieJar = CookieJar::fromArray(['cookieName' => 'testCookie'], 'guzzle.testhttp.com');
$param['cookies'] = $cookieJar;
$client->request('POST', '/post', $params);
6.multipart
$client->request('POST', '/post', [
'multipart' => [
[
'name' => 'baz',
'contents' => fopen('/path/to/file', 'r')
],
[
'name' => 'qux',
'contents' => fopen('/path/to/file', 'r'),
'filename' => 'custom_filename.txt'
],
]
]);
7.异步请求
use Psr\Http\Message\ResponseInterface;
use GuzzleHttp\Exception\RequestException;
$promise = $client->requestAsync('POST', '/post', ['json' => ['data' => 'hello world!']]);
$promise->then(
function (ResponseInterface $res) {
echo $res->getStatusCode() . "\n";
},
function (RequestException $e) {
echo $e->getMessage() . "\n";
echo $e->getRequest()->getMethod();
}
);
8.并发请求
use GuzzleHttp\Client;
use GuzzleHttp\Promise;
$client = new Client(['base_uri' => 'http://guzzle.testhttp.com/']);
// Initiate each request but do not block
$promises = [
'a' => $client->requestAsync('POST', '/post', ['json' => ['data' => 'hello test1!']]),
'b' => $client->requestAsync('POST', '/post', ['json' => ['data' => 'hello test2!']]),
'b' => $client->requestAsync('POST', '/post', ['json' => ['data' => 'hello test3!']]),
];
// Wait on all of the requests to complete.
$results = Promise\unwrap($promises);
// You can access each result using the key provided to the unwrap
// function.
echo $results['a']->getBody()->getContents(); // body 也有实现 __toString()调用getContents()
echo $results['b']->getHeader('Content-Length');
