问题

在与第三方API的速率限制作斗争，他们限制每个IP地址每秒n个请求

预期

轻松调用API，无需

解决方案

使用此包，您将使用

• 通过代理进行IP轮换
• 速率限制器来控制请求速率

安装

您可以通过以下两种方法安装此库

使用composer

此项目使用composer。

composer require mars-php-utils/rate-limit-bypass

手动安装

在以下位置检出代码库

vendor_dev/rate-limiter-bypass

composer.json

"repositories": [
    {
        "type": "path",
        "url": "vendor_dev/rate-limiter-bypass"
    }
],

如何使用

假设您正在使用curl进行请求

function getUser($id) {
    $curl = curl("https://example-api.com/user/$id");
    curl_setopt_array($curl, $your_options);
    $response = curl_exec($curl);
    return $response;
}

您只需要做以下操作

use RateLimitBypass\IpRateLimitHelper;


$max_request_per_second = 10;
$proxies = [...];
$rotator = new IpRateLimitHelper($proxies, $max_request_per_second);

function getUser($id) {
    $proxy_opt = $rotator->tap();
    
    $curl = curl("https://example-api.com/user/$id");

    $your_options = array_merge_recursive($your_options, $proxy_opt);
    
    curl_setopt_array($curl, $your_options);
    $response = curl_exec($curl);
    return $response;
}

通过API密钥轮换进行限制

use RateLimitBypass\ApiKeyRateLimitHelper;

$max_request_per_second = 10;
$api_keys = [...];
$rotator = new ApiKeyRateLimitHelper($api_keys, $max_request_per_second);

function getUser($id) {
    $api_key = $rotator->tap(); // api key can be in query string, headers, path, ... depend on the API endpoint
    
    $curl = curl("https://example-api.com/user/$id?apiKey=$api_key");
    curl_setopt_array($curl, $your_options);
    $response = curl_exec($curl);
    return $response;
}

本地开发

composer.json

"repositories": [
        {
            "type": "path",
            "url": "vendor_dev/mars-php-utils/rate-limit-bypass"
        }
    ],

然后运行

composer require mars-php-utils/rate-limit-bypass

composer会将vendor/mars-php-utils符号链接到vendor_dev/mars-php-utils
