ajax - 搜索应用程序时出现 WSO2 API Manager Store 错误

问题描述

我正在使用 WSO2 API Manager 2.1.0。当我在商店中搜索应用程序时，有时会出现以下错误。一旦发生这种情况，将无法搜索任何其他应用程序，需要重新启动 API Manager 才能正常运行。

非常感谢任何解决此问题的支持步骤。

提前致谢。

数据表错误

PS：我还添加了后端日志。

解决方案

如果在 API 管理器中找不到特定于应用程序的条目，或者在尝试检索应用程序信息时网络调用中存在任何问题，则上述 Ajax 错误是一般错误。

为了进一步调查，

  • 您可以在浏览器中打开开发者控制台并在操作过程中检查网络。检查与检索（ ）相关的操作（网络调用）https://<hostname>:<port>/store/site/blocks/application/application-list/ajax/application-list.jag是否有问题，如果在您的环境中配置了 LB 和 Proxy 配置，请务必检查。
  • 验证错误是仅填充到一组应用程序还是随机填充到所有应用程序。如果这只发生在一组应用程序中，则存储在数据库中的数据可能会出现问题。相应的应用程序输入了部分数据，或者应用程序订阅的 API 有部分数据

关注 URL 配置和 LB 配置，因为它可能是问题的更普遍原因。
