Question

This is the code有问题。我从moz网站上得到了这个。

此代码与Moz API连接，让我们批量检查域权限/页面权限。它工作正常，但问题是它允许最多200个URL。

因此，如果有超过200个域，我会尝试在API上发出多个请求。我这样做是为了通过在代码中创建2个API请求来检查400个域。这是修改后的代码。

<?php
    // Get your access id and secret key here: https://moz.com/products/api/keys
    $accessID = "ACCESS_ID_HERE";
    $secretKey = "SECRET_KEY_HERE";

    // Set your expires times for several minutes into the future.
    // An expires time excessively far in the future will not be honored by the Mozscape API.
    $expires = time() + 300;

    // Put each parameter on a new line.
    $stringToSign = $accessID."\n".$expires;

    // Get the "raw" or binary output of the hmac hash.
    $binarySignature = hash_hmac('sha1', $stringToSign, $secretKey, true);

    // Base64-encode it and then url-encode that.
    $urlSafeSignature = urlencode(base64_encode($binarySignature));

    // Add up all the bit flags you want returned.
    // Learn more here: https://moz.com/help/guides/moz-api/mozscape/api-reference/url-metrics
    $cols = "68719476736";

    // Put it all together and you get your request URL.
    $requestUrl = "http://lsapi.seomoz.com/linkscape/url-metrics/?Cols=".$cols."&AccessID=".$accessID."&Expires=".$expires."&Signature=".$urlSafeSignature;

    // Put your URLS into an array and json_encode them.
    $batchedDomains = array('www.moz.com', 'www.apple.com', 'www.pizza.com');
    $batchedDomains1 = array_slice($batchedDomains, 0, 200);
    $batchedDomains2 = array_slice($batchedDomains, 200, 200);

    $encodedDomains1 = json_encode($batchedDomains1);
    $encodedDomains2 = json_encode($batchedDomains2);

    $options1 = array(
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_POSTFIELDS     => $encodedDomains1
    );
    $options2 = array(
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_POSTFIELDS     => $encodedDomains2
    );

    $ch1 = curl_init( $requestUrl );
    curl_setopt_array( $ch1, $options1 );
    $content1 = curl_exec( $ch1 );
    curl_close( $ch1 );

    $ch2 = curl_init( $requestUrl );
    curl_setopt_array( $ch2, $options2 );
    $content2 = curl_exec( $ch2 );
    curl_close( $ch2 );

    $contents1 = json_decode( $content1 );
    $contents2 = json_decode( $content2 );

    $contents = json_decode($content);
    print_r($contents1);
    print_r($contents2);

?>

这适用于2个请求，但如果我必须检查1000个或可能是2000个域，那么我将不得不创建20个此代码块来处理所有域。

我正在寻找一种自动化此过程的方法。如果要检查的域名超过200个，代码将自动创建200个批次（通过拆分数组）并为每个批次生成API请求，然后再次合并结果。

如果将域存储在数据库表中，则可以创建一个获取所有行并返回数组的函数。

假设您获得了一个名为$domains

的200多个元素的数组

$domains = array(
        'www.moz.com',
        'www.apple.com',
        'www.pizza.com'
        // ...
    );

使用array_chunk我们将其分成200个元素的块，我们调用一个函数向moz api发送每个块的请求。
最后一个块可能包含少于200个元素。

$chunks = array_chunk($domains,200);

foreach($chunks as $chunk){
    $response = sendRequest(json_encode($chunk));
    var_dump($response);
}

function sendRequest($jsonString){
    // Get your access id and secret key here: https://moz.com/products/api/keys
    $accessID = "ACCESS_ID_HERE";
    $secretKey = "SECRET_KEY_HERE";

    // Set your expires times for several minutes into the future.
    // An expires time excessively far in the future will not be honored by the Mozscape API.
    $expires = time() + 300;

    // Put each parameter on a new line.
    $stringToSign = $accessID."\n".$expires;

    // Get the "raw" or binary output of the hmac hash.
    $binarySignature = hash_hmac('sha1', $stringToSign, $secretKey, true);

    // Base64-encode it and then url-encode that.
    $urlSafeSignature = urlencode(base64_encode($binarySignature));

    // Add up all the bit flags you want returned.
    // Learn more here: https://moz.com/help/guides/moz-api/mozscape/api-reference/url-metrics
    $cols = "68719476736";

    // Put it all together and you get your request URL.
    $requestUrl = "http://lsapi.seomoz.com/linkscape/url-metrics/?Cols=".$cols."&AccessID=".$accessID."&Expires=".$expires."&Signature=".$urlSafeSignature;

    $options = array(
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_POSTFIELDS     => $jsonString
    );

    $ch = curl_init( $requestUrl );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    curl_close( $ch );

    return json_decode($content);
}

您可以收集数组中的$response变量，稍后再使用它们。

sendRequest函数中的代码完全可循环使用，我们不需要反复重写，只需将参数传递给CURLOPT_POSTFIELDS

试图让这个PHP代码适用于批量操作
