是什么导致了 NodeJS 中的错误 "Cannot set uncompiled validation rules without configuring a validator"？

Question

这是我目前的情况。

'use strict';

const Hapi = require("@hapi/hapi");
const Joi = require("@hapi/joi")

const server = new Hapi.Server({ host: "0.0.0.0", port: 80 });

server.route({
    method: "POST",
    path: "/board",
    options: {
        validate: {
            payload: {
                name: Joi.object({
                    name: Joi.string().min(1).max(15)
                })
            }
        }
    },
    handler: async (request, h) => {
        // do stuff
    }
});

server.start();

这会产生错误

我原以为这会验证请求，但它却生成了一条错误消息，指出很少有关于如何修复的详细信息。

Answer 1

应该是

'use strict';

const Hapi = require("@hapi/hapi");
const Joi = require("@hapi/joi")

const server = new Hapi.Server({ host: "0.0.0.0", port: 80 });

server.route({
    method: "POST",
    path: "/board",
    options: {
        validate: {
            payload: Joi.object({
                    name: Joi.string().min(1).max(15)
                })
        }
    },
    handler: async (request, h) => {
        // do stuff
    }
});

server.start();

payload: Joi.object({ name: Joi.string().min(1).max(15) })

Answer 2

On upgrading to Latest hapi，检查您的代码以进行路由验证和 response.schema 设置，以及您是否正在传递必须编译的值（请参阅上面缺少 Joi.object() 作为典型情况），要么用 Joi.object() 包装你的模式，要么调用 server.validator(Joi)
