rt，首先进入前端，然后点击 “文章广场” 按钮，然后点击 “讨论区” 按钮后立刻退回上一页面，就会出现：

{
    "instance": "main",
    "template": "error",
    "status": 404,
    "locale": "zh-CN",
    "data": {
        "errorCode": 404,
        "errorType": "Symfony\\Component\\HttpKernel\\Exception\\NotFoundHttpException",
        "errorMessage": "",
        "errorData": []
    },
    "user": {
        "uid": 670355,
        "avatar": "https://cdn.luogu.com.cn/upload/usericon/670355.png",
        "name": "Nuclear_Fish_cyq",
        "slogan": "> 最后在线时间：2024年7月21日16时42分|ENFP-T|小六/淮初|B站：不想取名的核动力鱼 < 由 exOIso 发送激光",
        "badge": null,
        "isAdmin": false,
        "isBanned": false,
        "color": "Orange",
        "ccfLevel": 5,
        "background": "https://cdn.luogu.com.cn/upload/image_hosting/jpkw9czg.png",
        "verified": true
    },
    "time": 1721551427.165754
}
