Question

我发送AJAX POST request到handleSession.php文件，该文件用于获取POST参数，然后将它们添加到会话中。但是，handleSession.php file fails to update the session data。这是AJAX request code正常工作

var req = JSON.stringify({
   body:body,
   img:img,
   title:title,
   id:id,
   category:category}
);

fetch("handleSession.php", {
  method:"POST",
  body: req
})
.then((data) => data.text())
.then(data => JSON.parse(data))
.then(data => console.log(data))
.catch((err) => console.log(err))

下面是handleSession.php文件，该文件应该将$_POST数据解析为会话

<?php
ob_start();
session_start();

$data = json_decode(file_get_contents('php://input'), true);

$arr = array(
  "title" => "",
  "img" => "",
  "body" => "",
  "id" => "",
  "category" => ""
);

foreach ($data as $key => $value) {
    $arr[$key] = $data[$key];
}

$_SESSION["fav"] = $arr["title"];
//even if I say $_SESSION["FOO"] = "bar"; it still doesn't work

echo json_encode($arr);

?>

因此，在页面顶部session_start()和ob_start()的另一个页面上，我已经说过

if(isset($_SESSION["fav"])){
  echo $_SESSION["fav"];
}else{
  echo "Session fav not set";
}

它总会进入其他条件

任何帮助表示赞赏！
