已弃用的 API 在 WSO2 API Manager 4.1.0 中不可见答案

【问题标题】：Deprecated API is not viewable in WSO2 API Manager 4.1.0已弃用的 API 在 WSO2 API Manager 4.1.0 中不可见
【发布时间】：2023-02-06 02:52:07
【问题描述】：

有Pizzashack sample API部署在WSO2 APIm 4.1.0

但是，API 状态有时已移至 Deprecated。

当点击此 API 进行一些更改（删除/移动到其他状态等）时，它正在加载，没有得到任何响应。

在wso2carbon.log 中得到以下日志

错误：

我们如何获得概览页面或对同一 API 执行其他操作？

【问题讨论】：

当您创建新版本的 API 并在发布时试图弃用以前的版本时，是否会发生这种情况？

标签： wso2 wso2-api-manager

【解决方案1】：

这是 APIM 4.1.0 中已知的 issue。如果您创建新版本的 API（v1.0.0 和 v2.0.0）并且在 v2.0.0 的发布步骤中，您可以选择在发布 v2.0.0 时弃用 v1.0.0。此流程中存在一个错误，它破坏了 v1.0.0 的工件。 v1.0.0 状态更改为已弃用，但您无法打开或删除现有 API。这已由fix 修复。

作为解决方案，您需要修复损坏的工件。幸运的是，您应该有一个未损坏的版本，您可以使用 v2.0.0 中的字段来修复损坏的 v1.0.0。

登录到碳控制台。
从 Main 选项卡的 Resources 部分中的“浏览”访问注册表工件。
导航至/_system/governance/apimgt/applicationdata/provider/<user>/<API_Name>/
在这里您可以找到两个版本的 API。导航到最新版本并打开 api 工件。
导航到损坏的版本并打开 api 工件。
您应该能够看到损坏版本中的某些数据丢失，并且它们已填充到工作版本中。通过手动添加这些字段，您应该能够让损坏的版本再次运行。
