node.js - PUT 请求 404 未找到错误邮递员？Node.js 快递

Question

尝试发出 PUT 请求以更新我的 MERN 应用程序的房屋时。该路由似乎在服务器端不起作用，在邮递员中它显示 404 not found 错误。我猜测这可能是我的路线设置方式，因为它甚至无法识别我正在尝试发出 PUT 请求。我的所有其他路线都有效，但由于某种原因，我在邮递员中收到 index.html 错误。PUT 请求位于 HouseList Route 代码的底部。

不要一起使用async/awaitand .then .catch，使用async/awaitwith try/catch，使用时不需要返回，res所以你应该像这样更新所有查询：

try {
    let data = await House.findByIdAndUpdate({_id: req.params.id}, req.body).toObject()
    res.status(200).json(data)
} catch (error) {
    res.status(404).json({"error": error})
}

如果您希望 find 的结果是一个普通对象 javascript，您可以使用lean()forfind和使用toObjectforfindOne或者findById您也可以尝试这样

let data = await House.findByIdAndUpdate({_id: req.params.id}, req.body)
res.status(200).json({data})
