我被困在这个问题好几天了，无法解决它，所以如果可以的话请帮忙，我正在尝试从表单创建一个帐户，但我猜它会发送空的东西
我创建了我的模型并需要所有用户名、电子邮件和密码，但是当我删除“必需”时 此错误消失，但在数据库中未创建任何帐户

我还评论了 bcrypt 代码，因为它发送了另一个错误，指出“错误：需要数据和盐参数”

Answer 1

在您的模型中，您提到了

required: true

、

username

和

password

的

email

，因此您需要将值传递到前端或邮递员中的必填字段。或者您可以处理错误而不是像这样的必填字段。

if (!username|| username== "") {
    return res.send("username is required");
  }

和

"Error: data and salt arguments required"

是因为您需要传递参数

data

和

salt

值。如果没有这两个参数，该方法将返回错误。

这是一个加密密码的简单示例。

await bcrypt.hash(password, 10);
