// fix: 文档给出的引入方式报错
import asyncValidator from 'async-validator';
const Validator = asyncValidator.default;
// 定义校验规则
const rules = {
name: {
type: 'string',
required: true,
validator: (rule, value) => value === 'muji',
},
age: {
type: 'number',
asyncValidator: (rule, value) => {
return new Promise((resolve, reject) => {
if (value < 18) {
reject('too young'); // reject with error message
} else {
resolve();
}
});
},
},
};
const validator = new Validator(rules);
let data = { name: 'Tom', age: 16 };
validator
.validate(data)
.then(() => {
// validation passed or without error message
console.log('validate passed');
})
.catch(({ errors, fields }) => {
console.log(errors, fields);
});打印出的校验信息
