我有以下 openapi 文件架构

简而言之，架构（问题所在）就像
Web3SigningCredential -> { Web3SigningCredentialPrivateKeyHex、Web3SigningCredentialGethKeychainPassword、Web3SigningCredentialNone、Web3SigningCredentialCactusKeychainRef 之一 -> > Web3SigningCredentialType
当我尝试使用
解析它时openapi-generator generate --input-spec file_mentioned_above -g go -o some_path
我收到一个错误说明
Exception in thread "main" java.lang.RuntimeException: Could not process model 'Web3SigningCredential'.Please make sure that your schema is correct!

但是当我在上面提到的命令中使用语言 typescript-axios 时，同样的工作
openapi-generator generate --input-spec file_mentioned_above -g typescript-axios -o some_path
我对上面提到的规范文件做错了什么还是与 Go for openapi-generator 有关？
解决方法
尝试重新组织架构以使用 allOf 继承而不是 oneOf。还要确保在基本架构中指定鉴别器 mapping。如果没有 mapping，API 定义假定子架构与鉴别器属性值具有相同的名称，而在您的示例中并非如此。
这是一个 YAML 版本，您可以使用 https://www.json2yaml.com/ 将其转换为 JSON。
components:
schemas:
Web3SigningCredential:
type: object
required:

discriminator:
propertyName: type
mapping:
CACTUS_KEYCHAIN_REF: Web3SigningCredentialCactusKeychainRef

Web3SigningCredentialGethKeychainPassword:
allOf:

required:

- secret
properties:
ethAccount:
type: string

minLength: 64
maxLength: 64
nullable: false
secret:
type: string
description: A geth keychain unlock password.
minLength: 0
maxLength: 65535
相应地更新 Web3SigningCredentialCactusKeychainRef、Web3SigningCredentialPrivateKeyHex 和 Web3SigningCredentialNone 架构。
