警告:输入变量超过1000 [英] Warning: Input variables exceeded 1000

问题描述

我正在PHP中构建类似RESTS的服务，该服务应接受大型JSON发布作为主要数据(我发送和读取数据的方式与此处讨论的非常相似:

I'm building a RESTS like service in PHP that should accept a large JSON post as main data (I send and read the data much like discussed here: http://forums.laravel.io/viewtopic.php?id=900)

问题是PHP给了我以下警告:

The problem is that PHP gives me the following Warning:

<b>Warning</b>:  Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in <b>Unknown</b> on line <b>0</b><br />

有没有什么方法可以让PHP不计算输入变量(或者我应该停止启动警告)?

Is there any way to get PHP not count input variables (or should I just surpress startup warnings)?

推荐答案

我发现直接在PHP中(通过file_get_contents('php://input'))直接处理json数据的正确方法是确保请求设置了正确的内容类型，即Content-type: application/json在HTTP请求标头中.

I found out that the right way to handle json data directly in PHP (via file_get_contents('php://input')) is to make sure the request sets the right content-type i.e. Content-type: application/json in the HTTP request header.

在我的情况下，我要求使用curl结合以下代码从php请求页面:

In my case I'm requesting pages from php using curl with to this code:

function curl_post($url, array $post = NULL, array $options = array()) {
  $defaults = array(
    CURLOPT_POST => 1,
    CURLOPT_HEADER => 0,
    CURLOPT_URL => $url,
    CURLOPT_FRESH_CONNECT => 1,
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_FORBID_REUSE => 1,
    CURLOPT_TIMEOUT => 600
  );
  if(!is_null($post))
    $defaults['CURLOPT_POSTFIELDS'] = http_build_query($post);
  $ch = curl_init();
  curl_setopt_array($ch, ($options + $defaults));
  if(($result = curl_exec($ch)) === false) {
    throw new Exception(curl_error($ch) . "\n $url");
  }
  if(curl_getinfo($ch, CURLINFO_HTTP_CODE) != 200) {
    throw new Exception("Curl error: ". 
      curl_getinfo($ch, CURLINFO_HTTP_CODE) ."\n".$result . "\n");
  }
  curl_close($ch);
  return $result;
}

$curl_result = curl_post(URL, NULL,
    array(CURLOPT_HTTPHEADER => array('Content-Type: application/json'),
      CURLOPT_POSTFIELDS => json_encode($out))
    );

请注意CURLOPT_HTTPHEADER => array('Content-Type: application/json')部分.

在接收方，我正在使用以下代码:

On the receiving side I'm using the following code:

$rawData = file_get_contents('php://input');
$postedJson = json_decode($rawData,true);
if(json_last_error() != JSON_ERROR_NONE) {
  error_log('Last JSON error: '. json_last_error(). 
    json_last_error_msg() . PHP_EOL. PHP_EOL,0);
}

请勿更改max_input_vars变量..由于更改了设置正确标题的请求，所以我关于max_input_vars的问题消失了.显然，PHP不会在设置某些Content-type的情况下评估post变量.

Do not change the max_input_vars variable. Since changing the request to set right headers my issue with max_input_vars went away. Apparently does not PHP evaluate the post variables with certain Content-type is set.
