Node.js 没有得到任何响应-Express验证程序

我正在使用最新版本的express validator进行验证。 我没有得到任何回应，但是旧方法，即

checkBody

工作正常，而新方法，即

check（'keyName'）

工作不正常

下面是我的代码

package.json

"express-validator": "^5.0.3",

我注意到节点js无法从

auth.validation.js

中的函数

validateLogin

继续运行

谁能告诉我上面的代码有什么问题吗

在控制台内部，仅显示1

我附上截图供参考

---

validateLogin

和

checkValidationResult

正在作为中间工具应用于您的路线。在中间件中，使用

next（）

方法调用队列中的下一个中间件。就像在您的

检查验证结果中一样

在
validateLogin
的情况下，它不会将控制权传递给下一个中间件。但是
expressvalidator
v5中的
check
方法本身就是一种中间件方法。因此，我想它不会正常工作

我们需要使用简单数组，而不需要创建函数

代码应该是这样的

auth.validation.js

var authValidator = require('./../validation/auth.validation');
var routes = require('express').Router();

routes.post('/login', [

如果您提供示例，可能会更有帮助。死代码：
const{matchedData，sanitize}=require（'express-validator/filter'）如果您提供示例，可能会更有帮助。Dead-code:
const{matchedData，sanitize}=require（'express-validator/filter'）死代码：
const{matchedData，sanitize}=require（'express-validator/filter'）我在其他验证函数中使用sanitize方法，这就是我在那里声明常量的原因。整个/check要求已被弃用，但除此之外，这是一个很好的答案死代码：
const{matchedData，sanitize}=require（'express-validator/filter'）我在其他验证函数中使用了sanitize方法，这就是为什么我在那里声明了常量。整个/check要求都被否决了，但除此之外，这是一个很好的答案
