Question

我试图从medium复制亚当的例子。

    const app = express();
app.use(expressLogger);
app.use(BodyParser.json());

app.post('/signup', celebrate({
  body: Joi.object().keys({
    name: Joi.string().required(),
    age: Joi.number().integer(),
    role: Joi.string().default('admin')
  }),
  query: {
    token: Joi.string().token().required()
  }
}), (req, res) => {
    logger.debug('Calling res.send');
    res.json({ success: true, data : { name, age, role }});
});

这是错误

 "message": "celebrate request validation failed",
    "validation": {
        "query": {
            "source": "query",
            "keys": [
                "token"
            ],
            "message": "\"token\" is required"

        }

邮递员POST请求

{
    'name' : 'John J.',
    'age' : 23,
}

我将令牌设置为参数，现在可以正常工作。我现在出现参考错误。

<body>
    <pre>ReferenceError: name is not defined<br>

这是简单的示例。这就是Pino记录器显示的内容

err":{"type":"Error","message":"failed with status code 500","stack":"Error: failed with status code 500\n    at ServerResponse.onResFinished (/home/trajche/pract/joi1/node_modules/pino-http/logger.js:73:38)\n    at ServerResponse.emit (events.js:326:22)\n    at onFinish (_http_outgoing.js:751:10)\n    at callback (_stream_writable.js:501:21)\n    at afterWrite (_stream_writable.js:454:5)\n    at afterWriteTick (_stream_writable.js:441:10)\n    at processTicksAndRejections (internal/process/task_queues.js:79:21)"},"responseTime":3,"msg":"request errored"}
ReferenceError: name is not defined

当您尝试使用res.json({ success: true, data : { name, age, role }});返回数据时，未定义变量name，age或role。您需要先从请求正文中检索它们。

与

res.json({ success: true, data : { name: req.body.name, age: req.body.age, role: req.body.role }});

也许是更好的方法

const { name, age, role } = req.body;
res.json({ success: true, data : { name, age, role }});

为什么庆祝请求验证失败？
