如何在 AJV 中使用超模式？

Question

我需要根据使用 hyper-schema 的现有模式实施 json 模式验证器为此，我尝试利用 ajv 库（版本 6.12.2），这是我的实现：

const Ajv = require('ajv');
// Ajv does not allow to import schema by uri, so I download them and put thems in thoses files
// I've download them directly from http://json-schema.org http://json-schema.org/draft-07/hyper-schema# and http://json-schema.org/draft-07/links#
const hyperSchema = require('./schemas/draft07/hyper-schema.json');
const linkSchema = require('./schemas/draft07/links.json');
var ajv = new Ajv();
ajv.addSchema([hyperSchema, linkSchema]); // unsure if I should use addSchema or addMetaSchema, so I tried both without success

出现以下错误：

<path_to_project>\node_modules\ajv\lib\ajv.js:352
    throw e;
    ^
[MissingRefError: can't resolve reference http://json-schema.org/draft-07/links# from id http://json-schema.org/draft-07/hyper-schema#] {        
  message: "can't resolve reference http://json-schema.org/draft-07/links# from id http://json-schema.org/draft-07/hyper-schema#",     
  missingRef: 'http://json-schema.org/draft-07/links',
  missingSchema: 'http://json-schema.org/draft-07/links'
}

或者这个，如果我使用 ajv.addSchema([linkSchema, hyperSchema]);

<path_to_project>\node_modules\ajv\lib\ajv.js:93
    if (!v) throw new Error('no schema with key or ref "' + schemaKeyRef + '"');
            ^


Error: no schema with key or ref "http://json-schema.org/draft-07/hyper-schema#"

    at Function.Module._load (internal/modules/cjs/loader.js:901:14)

我也尝试过使用 ajv.addSchema([hyperSchema, linkSchema], undefined, true) 跳过架构验证，但是在导入我的架构时失败并出现以下错误（在验证超级架构时）：

<path_to_project>\node_modules\ajv\lib\ajv.js:179
    else throw new Error(message);
         ^ 

Error: schema is invalid: data.properties['$ref'] should be object,boolean

这里如何处理超模式？即使 hyper-schema.json 似乎已加载，它也无法引用 links。与 addSchema 对多个文件的错误使用有关，还是由于 ajv 中的超模式处理？

好心人在与 AJV (https://github.com/ajv-validator/ajv/issues/1236) 关联的 Github 中回答了问题。

该错误是由于架构中的错误定义引起的，而不是在使用 AJV 的方式中。
