我有一个小问题，重点是我的数组没有获取内容。
$staff = array(
"permissions" => false,"staff" => true,"group" => 3
);
echo json_encode($staff);
let staff = [];
$.ajax({
type: "POST",url: "../includes/signin.inc.php",})
.done(function (data) {
staff = JSON.parse(data);
console.log(staff);
})
.fail(function (xhr,status,error) {
alert(status);
});
我有这个错误：
Unexpected end of JSON input
只是我想在 js 中将数组 $staff 放入员工中。
你应该使用
header('Content-Type: application/json');
在将您的 JSON 从服务器发送到客户端之前。那么错误就会消失。
,好吧，我在浏览器中检查了网络，我的变量为空。
现在可以了，代码：
$_SESSION['group'] = $row['permissions'];
include 'group.inc.php';
header('Content-Type: application/json');
session_start();
$group = $_SESSION['group'];
switch ($group) {
case '0':
break;
case '1':
$_SESSION['permissions'] = false;
echo json_encode($_SESSION['staff'] = true);
$_SESSION['group'] = 1;
break;
case '2':
$_SESSION['permissions'] = false;
echo json_encode($_SESSION['staff'] = true);
$_SESSION['group'] = 2;
break;
case '3':
$staff = array(
"permissions" => false,"staff" => true,"group" => 3
);
echo json_encode($staff);
break;
}
console.log(data.group);
console.log(data.staff);
console.log(data.permissions);
结果：
{permissions: false,staff: true,group: 3}
group: 3
permissions: false
staff
