Question

我正在使用此代码并创建了一个微服务

const { json, send } = require('micro')
const { router, post } = require('microrouter')
const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY)
console.log(process.env.STRIPE_SECRET_KEY)
module.exports = router(
    post('/', async (req, res) => {
        const data = await json(req)
        try {
            const { status } = await stripe.charges.create(data)
            send(res, 200, { status })
        } catch (err) {
            send(res, 500, { message: err.message })
        }
    })
)

我可以在此处使用post发出microrouter请求，但是如何验证有效载荷主体以仅获取必需的字段。

如果有人知道用于验证微服务发布有效载荷的任何模块，请提供帮助。

您可以使用joi npm并表达验证器

const Joi = require("joi");
const validate = require("express-validation");

const validationSchema = {
      body: {
        Id: Joi.string()
          .guid()
          .required(), // mandatory
        FirstName: Joi.string().required(), // mandatory
        LastName: Joi.string().required(), // mandatory
        Email: Joi.string()
          .email({ minDomainAtoms: 2 })
          .required(), // mandatory
        Password: Joi.string().required(), // mandatory
        createdOn: Joi.date()
          .timestamp()
          .required(), // mandatory

      }
    };

路由器文件

module.exports = router(
    post('/',validate(validationSchema), async (req, res) => {
        const data = await json(req)
        try {
            const { status } = await stripe.charges.create(data)
            send(res, 200, { status })
        } catch (err) {
            send(res, 500, { message: err.message })
        }
    })
)

您遇到了这么普遍的问题，据我了解，您可以将这些负载用于https://validatejs.org/#validators

这是电子邮件验证示例：

var constraints = {
  from: {
    email: true
  }
};

validate({from: null}, constraints);
// => undefined

validate({from: ""}, constraints);
// => {"email": ["From is not a valid email"]}

validate({from: "nicklas@ansman"}, constraints);
// => {"email": ["From is not a valid email"]}

// Any TLD is allowed
validate({from: "nicklas@foo.faketld"}, constraints);
// => undefined

// Upper cased emails are allowed
validate({from: "NICKLAS@ANSMAN.SE"}, constraints);
// => undefined

constraints = {
  from: {
    email: {
      message: "doesn't look like a valid email"
    }
  }
};

validate({from: "foobar"}, constraints);
// => {"email": ["From doesn't look like a valid email"]}

// It allows unicode
validate({from: "first.läst@example.com"}, constraints);
// => undefined

如何使用微路由器验证有效载荷？
