弃用

该功能已从Web标准中删除。尽管一些浏览器可能仍然支持它，但它正在被丢弃。避免使用它并尽可能更新现有的代码；请参阅本页底部的兼容性表格来指导您的决定。请注意，此功能可能随时停止工作。

不推荐使用的HTTP Content-Security-Policy（CSP）report-uri指令指示用户代理报告违反内容安全策略的企图。这些违规报告由通过HTTP POST请求发送到指定URI的JSON文档组成。

尽管report-to指令旨在取代已弃用的report-uri指令，report-to但在大多数浏览器中仍不受支持。因此，对于当前浏览器的同时，还加入向前兼容的浏览器时获得的兼容性report-to支持，您可以同时指定report-uri和report-to：

Content-Security-Policy: ...; report-uri https://endpoint.com; report-to groupname

在支持的浏览器中report-to，report-uri指令将被忽略。

该指令本身没有任何影响，但仅与其他指令结合起来才有意义。

CSP版本	1
指令类型	报告指令

| 该指令在<meta>元素中不受支持。|

句法

Content-Security-Policy: report-uri <uri>;

<uri>将报告发布到的URI。

示例

请参阅Content-Security-Policy-Report-Only更多信息和示例。

Content-Security-Policy: default-src https:; report-uri /csp-violation-report-endpoint/

/csp-violation-report-endpoint/ 例如可以运行一个如下所示的PHP，它记录详细说明违规的JSON，并且如果该违规是第一个添加到日志文件的违规，则向管理员发送一封电子邮件：

<?php// Start configure
$log_file = dirname(__FILE__) . '/csp-violations.log';
$log_file_size_limit = 1000000; // bytes - once exceeded no further entries are added
$email_address = 'admin@example.com';
$email_subject = 'Content-Security-Policy violation';// End configuration
$current_domain = preg_replace('/www\./i', '', $_SERVER['SERVER_NAME']);
$email_subject = $email_subject . ' on ' . $current_domain;http_response_code(204); 
// HTTP 204 No Content$json_data = file_get_contents('php://input');
// We pretty print the JSON before adding it to the log file
if ($json_data = json_decode($json_data)) {
  $json_data = json_encode($json_data, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES); 
   if (!file_exists($log_file)) {    
   // Send an email
    $message = "The following Content-Security-Policy violation occurred on " .
      $current_domain . ":\n\n" .
      $json_data .      "\n\nFurther CPS violations will be logged to the following log file, but no further email notifications will be sent until this log file is deleted:\n\n" .
      $log_file;    mail($email_address, $email_subject, $message,         'Content-Type: text/plain;charset=utf-8');  
      } else if (filesize($log_file) > $log_file_size_limit) {    
      exit(0);  
      }  file_put_contents($log_file, $json_data, FILE_APPEND | LOCK_EX);
      }
      ?>
