Question

我有hapi的以下路线代码......

const routeConfig = {
  method: 'POST',
  path: '/user',
  config: {
    validate: {
      payload: {
        firstName: Joi.string().required(),
      }
    },
    handler
  }
}

所以，当我没有通过firstName它会抛出这样的错误

{
    "statusCode": 400,
    "error": "Bad Request",
    "message": "child \"firstName\" fails because [\"firstName\" is required]",
    "validation": {
        "source": "payload",
        "keys": [
            "firstName"
        ]
    }
}

现在，我需要在catch

中处理上述错误

const handler = async(request, reply) => {
  try {
    const payload = request.payload
    const createUser = await User.create(payload)
    let token = Helpers.createJwt(createUser) 
    reply({ success: true, message: 'User created successFully', token })
  } catch(err) {
     // need to do something here to handle the error like
     if (err) {
       reply ({ error: "firstName is required", message: "Signup unsuccessfull" })
     }
  }
}

有一个更好的解决方案：

config: {
        validate: {
            payload: {
                firstName: Joi.string().required(),
            },
            failAction(request, reply, source, error) {
              reply({
                error: 'badRequest',
              }).code(400);
            },
        },
    },

如果Joi验证失败，它将触发failAction并且您将能够处理错误（将其发送到日志服务和/或返回特定消息）。

它在文档中有点隐藏，但这里是the relevant part

我必须承认，我没有尝试用hapi 17 ......
