How to deal with PHP Post failing to obtain non-form data

This time I will show you how to deal with PHP Post that cannot obtain non-form data. What are the things to note when dealing with PHP Post that cannot obtain non-form data? The following is a practical case. Let’s take a look. .

When using vue-axios to post data to the backend, the PHP side cannot obtain the posted data.

Modify php.ini configuration

Find the php.ini

, find the enable_post_data_reading variable, and modify it to Open the state, comment out the prefix

; Whether PHP will read the POST data.
; This option is enabled by default.
; Most likely, you won't want to disable this option globally. It causes $_POST
; and $_FILES to always be empty; the only way you will be able to read the
; POST data will be through the php://input stream wrapper. This can be useful
; to proxy requests or to process the POST data in a memory efficient fashion.

enable_post_data_reading = On  //大约656行，修改此条

Getting non-form data

After collecting information, I found that vue-axios posts non-form data to the backend (different from Ajax). You need to use php://input when getting non-form data.

$raw = file_get_contents('php://input');//获取非表单数据
echo $raw;//输出结果

PS: When posting, the front-end request header must be set to

headers: {
  "Content-type": "application/json; charset=utf-8"
}
