Ajv,ajv-errors定义嵌套属性的自定义消息
- 在Ajv实例定义中添加插件ajv-errors。
const Ajv = require('ajv'); const ajvErrors = require('ajv-errors'); const ajv = new Ajv({allErrors: true}); ajvErrors(ajv);
- 在schema中使用"$data"关键字引用嵌套属性。
const schema = { type: 'object', properties: { name: { type: 'string' }, address: { type: 'object', properties: { city: { type: 'string', errorMessage: { type: 'should be a string', $data: { dataPath: '.address.city', }, }, }, state: { type: 'string', errorMessage: { type: 'should be a string', $data: { dataPath: '.address.state', }, }, }, }, }, }, };
- 按照需要定义嵌套属性的自定义错误消息。
ajv.compile(schema)({name: 'John', address: {city: 1, state: 2}}); // Output: // [ // { // keyword: 'type', // dataPath: '.address.city', // schemaPath: '#/properties/address/properties/city/type', // params: {type: 'string'}, // message: 'should be a string', // }, // { // keyword: 'type', // dataPath: '.address.state', // schemaPath: '#/properties/address/properties/state/type', // params: {type: 'string'}, // message: 'should be a string', // }, // ]
