问题描述
当我在React app中将带有json数据的POST请求发送到PHP服务器时,$ _POST为空. 而且php://input也不起作用.
When I send POST request with json data in React app to PHP server, $_POST is empty. And also php://input doesn't work.
我尝试使用以下代码.
PHP服务器端:
if($_SERVER['REQUEST_METHOD'] == "OPTIONS") {
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS');
header('Access-Control-Allow-Headers: Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization');
header('Access-Control-Max-Age: 1000');
header("Content-Length: 0");
header("Content-Type: text/plain");
} else if($_SERVER['REQUEST_METHOD'] == "POST") {
echo "Checking case1:\n";
echo "<br/>";
$data = json_decode(file_get_contents('php://input'), true);
var_dump($data);
echo "<br/>";
echo "Checking case2:\n";
echo "<br/>";
var_dump($_POST);
}
反应副代码:
axios.post(
'https://xx.xx.com/index2.php',
{
member: id
},
{
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Access-Control-Allow-Origin': '*'
},
withCredentials: true
}
)
PHP服务器正在CloudFlare上运行. 我想知道这是否与Cloudflare的缓存过程有关.
PHP server is running on CloudFlare. I wonder if this is related with Cloudflare's cache process or not.
希望对您有所帮助,谢谢.
I hope any helps, Thank you in advance.
推荐答案
从axios发送时,您需要更改标题
while sending from axios you need to change headers
headers: {
'Content-Type': 'multipart/form-data,multipart/form-data',
'Access-Control-Allow-Origin': '*'
}
