Curl 包装器捆绑包

为 symfony 框架提供的 Curl 包装器捆绑包
https://packagist.org.cn/packages/metaer/curl-wrapper-bundle

安装

composer require metaer/curl-wrapper-bundle

如果您使用 Symfony 4+ 且使用 symfony flex - 那就全部搞定了
如果您使用 Symfony 2 或 3（且不使用 symfony flex），请将其添加到 AppKernel.php 中

new \Metaer\CurlWrapperBundle\MetaerCurlWrapperBundle(),

基本用法

$options = [
    CURLOPT_URL => 'http://example.ex',
    CURLOPT_RETURNTRANSFER => true,
];
        
$cw = $container->get('metaer_curl_wrapper.curl_wrapper');

try {
    $result = $cw->getQueryResult($options);
} catch (CurlWrapperException $e) {
    //handle exception
}

通过控制器注入的基本用法

MyController {
    /**
     * @var CurlWrapper
     */
    private $curlWrapper;

    /**
     * MyController constructor.
     * @param CurlWrapper $curlWrapper
     */
    public function __construct(CurlWrapper $curlWrapper)
    {
        $this->curlWrapper = $curlWrapper;
    }
    
    public function myAction() {    
        $options = [
            CURLOPT_URL => 'http://example.ex',
            CURLOPT_RETURNTRANSFER => true,
        ];

        try {
            $this->curlWrapper->getQueryResult($options);
        } catch (CurlWrapperException $e) {
            //handle exception
        }
        
        return new Response('something');
    }
}

通过控制器动作参数的基本用法

MyController {
    public function myAction(CurlWrapper $curlWrapper) {    
        $options = [
            CURLOPT_URL => 'http://example.ex',
            CURLOPT_RETURNTRANSFER => true,
        ];

        try {
            $result = $curlWrapper->getQueryResult($options);
        } catch (CurlWrapperException $e) {
            //handle exception
        }
        
        return new Response('something');
    }
}

在另一个服务中自动装配的基本用法

<?php
namespace App\Service;

use Metaer\CurlWrapperBundle\CurlWrapper;
use Metaer\CurlWrapperBundle\CurlWrapperException;

class MyService
{
    /**
     * @var CurlWrapper
     */
    private $curlWrapper;
    
    /**
     * MyService constructor.
     * @param CurlWrapper $curlWrapper
     */
    public function __construct(CurlWrapper $curlWrapper)
    {
        $this->curlWrapper = $curlWrapper;
    }
    
    public function myMethod() {    
        $options = [
            CURLOPT_URL => 'http://example.ex',
            CURLOPT_RETURNTRANSFER => true,
        ];

        try {
            $result = $this->curlWrapper->getQueryResult($options);
        } catch (CurlWrapperException $e) {
            //handle exception
        }
    }
}

如何简单地更改服务行为或扩展

Symfony-4 示例

# config/packages/metaer_curl_wrapper.yaml
metaer_curl_wrapper:
    wrapper: custom_curl_wrapper

# services.yaml
services:
    # your services
    #...
    
    custom_curl_wrapper:
        class: 'App\MyCurlWrapper'

// src/MyCurlWrapper.php
namespace App;

use Metaer\CurlWrapperBundle\CurlWrapper;

class MyCurlWrapper extends CurlWrapper
{
    public function getQueryResult(array $curlOptions)
    {
        //your code here
        return 'something';
    }
    
    public function myCustomMethod()
    {
        //something else
    }
}

所以，您不需要复制粘贴整个类代码。只需更改您想要更改的方法即可。

另一种完成相同任务的方法

# services.yaml
services:
    # your services
    #...
    
    metaer_curl_wrapper.curl_wrapper:
        class: 'App\MyCurlWrapper'

超时设置

$connectionTimeout = 8; //seconds
$serverResponseTimeout = 20; //seconds

$options = [
    CURLOPT_CONNECTTIMEOUT => $connectionTimeout,
    CURLOPT_TIMEOUT => $serverResponseTimeout,
];

$cw->getQueryResult($options);
