如何解決php獲取不到form數(shù)據(jù)？

問(wèn)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(kāi)狀態(tài)，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(fā)現(xiàn)還是不行，繼續(xù)查閱資料。

獲取非表單數(shù)據(jù)

搜集資料之后，發(fā)現(xiàn)vue-axios向后端post的是非表單數(shù)據(jù)（Ajax不同），在獲取非表單數(shù)據(jù)時(shí)需要用php://input

$raw = file_get_contents('php://input');//獲取非表單數(shù)據(jù)echo $raw;//輸出結(jié)果 PS：post時(shí)前端請(qǐng)求頭要設(shè)置為 headers: {    "Content-type": "application/json; charset=utf-8"}
