导入API

将Swagger或OpenAPI定义的API导入到API网关，支持导入到新分组和导入到已有分组两种方式。导入前您需要在API定义中补全API网关的扩展定义。

导入到新分组注意事项

将API定义导入到一个新的分组，导入过程中系统会自动创建一个新的API分组，并将导入的API归属到该分组。

适用于将一份全新且完整的API导入到API网关。

导入API前，请注意以下事项：

API网关中API分组和API的配额满足需求。
使用Swagger info或OpenAPI info的title作为API分组名称，新创建的API分组名称不能与已有的API分组名称重名。
导入的API定义中，如果存在冲突，那么根据系统导入的先后顺序，先导入的API会显示导入成功，后导入的API会显示导入失败。例如导入的API定义中存在2个名称相同或请求路径相同的API，那么先导入的API会显示导入成功，后导入的会显示导入失败。
如果选择扩展覆盖，当导入API的扩展定义项名称与已有策略（ACL，流量控制等）名称相同时，则会覆盖已有策略（ACL，流量控制等）。
导入的API不会自动发布到环境，导入时可以选择“立即发布”或者“稍后发布”，您可以自行选择策略。

导入到已有分组注意事项

将API定义导入到一个已有的分组，导入过程中不会删除分组中已有的API，只是将新增的API导入分组。

适用于将一个新的API或者一个修改后的API导入到已有的分组。

导入API前，请注意以下事项：

API网关中API的配额满足需求。
导入的API定义与已有的API定义冲突时，您可以选择使用导入的API定义覆盖已有的API定义，或者保留已有的API定义，此时导入的API定义会显示导入失败。
如果选择扩展覆盖，当导入API的扩展定义项名称与已有策略（ACL，流量控制等）名称相同时，则会覆盖已有策略（ACL，流量控制等）。
导入的API不会自动发布到环境，导入时可以选择“立即发布”或者“稍后发布”，您可以自行选择策略。

操作步骤

进入API网关控制台页面。
根据实际业务在左侧导航栏上方选择实例。
在左侧导航栏选择“API管理 > API列表”。
单击“导入API”，具体操作请参考导入API设计文件。
您也可以参考以下示例导入API到API网关：
