If you need to access the raw POST body you should really favor the use of the php://inputstream over $HTTP_RAW_POST_DATAas per the relevant manual entry:
如果您需要访问原始 POST 正文，您应该真正赞成根据相关手册条目使用php://input流：$HTTP_RAW_POST_DATA
php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".
php://input 是一个只读流，允许您从请求正文中读取原始数据。对于 POST 请求，最好使用 php://input 而不是 $HTTP_RAW_POST_DATA，因为它不依赖于特殊的 php.ini 指令。此外，对于默认情况下未填充 $HTTP_RAW_POST_DATA 的那些情况，它是激活 always_populate_raw_post_data 的潜在内存密集型替代方案。php://input 不适用于 enctype="multipart/form-data"。
So, to access the POST body using php://input:
因此，要使用以下方法访问 POST 正文php://input：
$post = file_get_contents('php://input');
