問題描述
在使用vue-axios向后端post數據時,PHP端獲取不到post的數據。
問題解決
修改php.ini配置
找到php.ini配置文件,查找enable_post_data_reading變量,修改為打開狀態,注釋掉句前分好
; 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.
; http://php.net/enable-post-data-reading
enable_post_data_reading = On //大約656行,修改此條
修改配置后,發現還是不行,繼續查閱資料。
獲取非表單數據
搜集資料之后,發現vue-axios向后端post的是非表單數據(Ajax不同),在獲取非表單數據時需要用php://input
$raw = file_get_contents('php://input');//獲取非表單數據
echo $raw;//輸出結果
PS:post時前端請求頭要設置為
headers: {
"Content-type": "application/json; charset=utf-8"
}
