array [oneOf]验证

Question

我尝试验证可以具有2个对象类型（item_id和item_ref）的数组。 每个模型的item_id和item_ref都是有效的，但是当我尝试验证数组时会出错。

我做错了什么？

我使用AJV版本6.10

Ajv选项对象

            var options = {
                allErrors: true,
                verbose: true,
                removeAdditional: false,
                processCode: require('js-beautify').js_beautify     // for debugging, beautify generated source code
            };

我的测试代码

        var validateModel = function(modelName, model)
        {
            var SwaggerSchema = require('./test.json');

            var options = {
                allErrors: true,
                verbose: true,
                removeAdditional: false,
                processCode: require('js-beautify').js_beautify     // for debugging, beautify generated source code
            };

            var ajv = require('ajv')(options);
            ajv.addSchema(SwaggerSchema, 'swagger.json');

            var modelDef = { $ref: 'swagger.json#/definitions/' + modelName };
            var result = ajv.validate(modelDef, model);

            return {
                valid: result,
                errors: ajv.errors
            }
        };

        var itemId = {
            name: 'name of the item_id',
            id: '123'
        };

        var itemRef = {
            name: 'name of the item_reference',
            reference: 'ABCD',
            price: 12.34
        };

        var container = {
            name: 'name of the resource',
            items: [
                itemId,
                // itemRef
            ]
        };

        var validationItemId = validateModel("item_id", itemId);
        if(!validationItemId.valid)
        {
            var errorMsg = validationItemId.errors;
            var foo = 3;

            var foo = 3;
        }

        var validationContainer = validateModel("container", container);
        if(!validationContainer.valid)
        {
            var errorMsg = validationContainer.errors; // should match exactly one schema in oneOf
            var foo = 3;
        }
