为什么带while循环的PHP Curl会产生504超时？

Question

[好，我正在尝试从CSV文件中使用json数组创建一些虚拟卡。 CSV文件有100张我要创建的卡片。如果我尝试在csv文件中发布完整的100行，则会收到504错误。如果我只发布10行，则该帖子可以成功打印响应。

我将其托管在共享托管帐户上。我无法更改http.conf或任何其他Apache配置。

我的CSV文件

First,Lasy,DOB,Phone,Email,Address 1,Address 2,City,State,Zip,Country
John,Doe,1/1/2000,5555555555,[email protected],123 something street,,Atlanta,GA,00000,US
Jimmy,Doe,1/1/2000,5555555555,[email protected],123 something street,,Atlanta,GA,00000,US

我的代码。 。 。

$handle = fopen('sgvc.csv', 'r')
$header = fgetcsv($handle);
while(($data = fgetcsv($handle)) !== false){

        $sv = '{
      "VirtualCards":[{  
      "FirstName":"'.$data[0].'",  
     "LastName":"'.$data[1].'",  
     "DateOfBirth":"'.$data[2].'", 
    "Phone":"'.$data[3].'", 
     "Email":"'.$data[4].'", 
     "ProfileAddress":{  
      "AddressLine1":"'.$data[5].'", 
       "AddressLine2":"'.$data[6].'", 
       "City":"'.$data[7].'", 
       "State": "'.$data[8].'", 
       "PostalCode":"'.$data[9].'", 
       "Country":"'.$data[10].'", 
       }, 
      "GroupId": ""}]

     }';

        echo $sv;
       $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS,  $sv);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); 
        curl_setopt($ch, CURLOPT_TIMEOUT, 900);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: token ','Content-Type: application/json'));
        $result = curl_exec($ch);
        curl_close($ch);
    }
    fclose($handle);
}

我回应的json ..

    { "VirtualCards":[{ "FirstName":"John", "LastName":"Doe", "DateOfBirth":"2/3/1981", "Phone":"5555555555", "Email":"[email protected]", "ProfileAddress":{ "AddressLine1":"123something rd", "AddressLine2":"", "City":"atlanta", "State": "GA", "PostalCode":"00000", "Country":"US", }, "GroupId": "123",}] }
{ "VirtualCards":[{ "FirstName":"John", "LastName":"Doe", "DateOfBirth":"2/3/1981", "Phone":"5555555555", "Email":"[email protected]", "ProfileAddress":{ "AddressLine1":"123something rd", "AddressLine2":"", "City":"atlanta", "State": "GA", "PostalCode":"00000", "Country":"US", }, "GroupId": "123",}] } //...array of json

我试图理解这一点。例如将其放入数据块中或使用stream_context_create。有没有更好的方法来做到这一点，例如一次10条线？

504是网关超时错误。由于您的代码按顺序发送请求，因此php脚本可能需要很长时间才能回答。您可以尝试打印某些内容并将其flush()发送给客户端，或并行进行curl请求。

您可以使用curl_multi并行运行curl请求。这里有一个代码示例：PHP Parallel curl requests
