AssertionError: expected undefined to equal 201

Question

我有一个 post 用户 API（数据库是 Postgres），它在 postman 上运行良好，没有错误，我的 [=] 中有 bodyparser 13=], .type('json') 但我的测试返回 AssertionError: expected undefined to equal 201, I console.log(res), 这是未定义的。这是我的代码，我的 API 在前，用 mocha 和 chai 测试在后。

exports.post_user = (req, res) => {
    const {error} = validateUser(req.body);
    if (error) return res.status(422).json({ message: error.details[0].message });
    if (!req.file) return res.send('Please upload a file');
    bcrypt.hash(req.body.password, 10, async (err, hash) => {
        if (err) {
            res.status(500).json({
                message: 'retype password',
                error: err
            });
        } else {
            const text = `INSERT INTO 
    users(id, firstName, lastName, otherName, email, phoneNumber, userName, isAdmin, password, userImage, createdOn) 
    VALUES(, , , , , , , , , , ) 
    returning *`;
            const values = [
                uuidv4(),
                req.body.firstName,
                req.body.lastName,
                req.body.otherName,
                req.body.email,
                req.body.phoneNumber,
                req.body.userName,
                req.body.isAdmin,
                hash,
                req.file.path,
                moment(new Date())
            ];
            try {
                const { rows } = await db.query(text, values);
                const token = jwt.sign({
                    email: rows[0].email,
                    userId: rows[0].id
                }, process.env.SECRET,
                {
                    expiresIn: '24h'
                });
                return res.status(201).json({
                    message: 'user created successfully',
                    users: rows[0],
                    token: token,
                    request: {
                        type: 'GET',
                        url: 'http://localhost:3000/api/v1/user/' + rows[0].id
                    }
                });
            } catch (err) {
                return res.status(400).json({
                    message: 'an error occur',
                    error: console.error(err)
                });
            }
        }
    });


};

Answer 1

第 expect (body.status).to.be.equals(201) 行与您的控制器 returns 不符。您的响应正文没有状态。尝试 res.should.have.status(201) 或 expect (res.status).to.equal(201)

Answer 2

带有代码 (201) 的响应是一个特殊的响应，因为它不允许任何响应主体，如果您需要一个主体，您可以使用 200 (as a successful action)
