Question

我正在使用mongo express和node编写API，我现在有两个集合1）用户2）用户列表

我正在尝试为用户实现更改密码功能，并希望更新登录用户的密码。这是我的api代码。

对于值错误，面向转换为字符串失败。

所以我想要的是在我的创建用户架构中，当我从前端调用app.put api时，我的密码应该更新。通过编写确切的查询，请提供一些帮助。

当我尝试执行findOneandUpdate（）时，我得到了cast ti string错误。请任何身体帮助。或写下看跌请求。感谢的

您创建的变量newPassword是model对象，您将其作为string传递。

将您的query对象更改为：

    {$set: {password: request.body.newPassword}}

无法使用mongoose更新mongodb中的记录
