Symfony NotBlank constraint allow blank string

问题 I'm working with Symfony5 and ApiPlatform with phpunit for the tests I'm running tests on field validation. My issue comes from the fact that I want to restrain the user's possiblity to enter a blank string in a property named name as follow : /** * @ApiResource( * attributes={ * "normalization_context"={"groups"={"cons:read", "cons:list"}}, * "denormalization_context"={"groups"={"cons:write"}} * }, * collectionOperations={ * "get"={ * "mehtod"="GET", * "normalization_context"={"groups"={

Restify Api 开发经验

此文已由作者王振华授权网易云社区发布。欢迎访问网易云社区，了解更多网易技术产品运营经验。工作期间，一直在用Restify开发或维护大大小小的API系统，现在分享一下一些个人觉得不错的Tips。充分利用middleware机制这里的middleware指的就是处理请求过程中一个独立的小函数，众多Node社区的Web框架都采用类似这样的形式 function (req, res, next) {}，然后把这些handler函数叠起来组成一个线性模型来完成一次请求的生命周期。首先，看一下一个Resitfy Api应用的最核心的骨架 let restify = require('restify')let app = restify.createServer() app.use(restify.plugins.queryParser()) app.use(restify.plugins.bodyParser()) app.get('/api/users/list', listUsers) 这里使用middleware机制加载了两个插件，然后在自己定义的路由上使用自己的listUsers函数来处理，非常简单清晰。等一下，listUser不一定必须是一个handler函数，事实上可以是一个handler chain(函数的数组)。基于这个简单的思路

Keras predict gives different error than evaluate, loss different from metrics

阅读更多关于 Keras predict gives different error than evaluate, loss different from metrics

问题 I have the following problem: I have an autoencoder in Keras, and train it for a few epochs. The training overview shows a validation MAE of 0.0422 and an MSE of 0.0024. However, if I then call network.predict and manually calculate the validation errors, I get 0.035 and 0.0024. One would assume that my manual calculation of the MAE is simply incorrect, but the weird thing is that if I use an identity model (simply outputs what you input) and use that to evaluate the predicted values, the

五分钟带你了解Java是如何从容而优雅地实现接口数据校验

阅读更多关于五分钟带你了解Java是如何从容而优雅地实现接口数据校验

本篇文章给大家分享平时开发中总结的一点小技巧！在工作中写过Java程序的朋友都知道，目前使用Java开发服务最主流的方式就是通过Spring MVC定义一个Controller层接口，并将接口请求或返回参数分别定义在一个Java实体类中，这样Spring MVC在接收到Http请求(POST/GET)后，就会自动将请求报文自动映射成一个Java对象。这样的代码通常是这样写的： @RestController public class OrderController { @Autowired private OrderService orderServiceImpl; @PostMapping("/createOrder") public CreateOrderBO validationTest(@Validated CreateOrderDTO createOrderDTO) { return orderServiceImpl.createOrder(createOrderDTO); } } 这样的代码相信大家并不陌生，但在后续的逻辑实现过程中却会遇到这样的问题：“在接收请求参数后如何实现报文对象数据值的合法性校验？”。一些同学也可能认为这并不是什么问题，因为具体某个参数字段是否为空、值的取值是否在约定范围、格式是否合法等等，在业务代码中校验就好了
