使用Ajv验证带引用的OpenAPI Schema遇解析错误及整体验证疑问

• 解析OpenAPI Schema文件提取响应Schema片段验证响应体时，若响应Schema引用同一文件内的其他组件Schema，验证会失效，不清楚如何处理这类多引用场景。
• Ajv无法直接处理完整的OpenAPI Schema对象，报错：Error: strict mode: unknown keyword: "openapi"。想确认：是否可以直接对整个OpenAPI Schema进行验证？若存在大量引用，该如何组合多个Schema？
• 尝试组合至少两个Schema时，遇到引用解析错误：can't resolve reference testObject.json#/schemas/testObject from id http://example.com/schemas/searchResults.json。

测试文件：test.spec.yaml #

schemas:
    testObject:
      $id: http://example.com/schemas/testObject.json
      type: object
      properties:
        prop1:
          type: string
    searchResults:
      $id: http://example.com/schemas/searchResults.json
      type: object
      properties:
        testObjects:
          type: array
          items:
            $ref: "testObject.json#/schemas/testObject"

测试代码 #

import * as fs from "fs";

import Ajv from "ajv";
import * as yaml from "js-yaml";

describe("test", () => {
  it("should validate the openapi schema", async () => {
    const schema: any = yaml.load(fs.readFileSync("test.spec.yaml", "utf8"));

    const a = schema.schemas.searchResults;
    const b = schema.schemas.testObject;

    const ajv = new Ajv({
      strict: true,
      allErrors: true,
      verbose: false,
      schemas: [a, b],
    });

    const validate: any = ajv.getSchema(
      "http://example.com/schemas/searchResults.json"
    );
    const valid = validate({ testObjects: "foo" });
    if (!valid) throw new Error(JSON.stringify(validate.errors));
  });
});
