代码表单后端注册端点

exports.signUp= async (req, res, next) => {

    const newUser = new User({
        name: req.body.name,
        country: req.body.country,
        city:req.body.city,
        email: req.body.email,
        password: req.body.password,
        contactNo: req.body.contactNo,
        gender: req.body.gender,
    });
 try {
        await newUser.save();
    } catch (err) {
        const error = new HttpError(
            'Signing up failed, please try again.',
            500
        );
        res.json({
            message:  'Signing up failed, please try again.',
            error: error
        });
        return next(error);
    }

    const token = jwt.sign({email: req.body.email}, "token_validator", { expiresIn: "1h"});
    res.status(201).json({
        message: "SignUp Succsessfull",
        token: token
    });
};

解决方案

你能把你的渔获改为：

 catch (err) {
        res.status(500).json({
            message:  'Signing up failed, please try again.',
            error: error});
    }

您收到该错误是因为您没有设置正确的错误状态。
