Azure Function 在部署后偶尔仍运行旧代码

Question

有时，在将最新位部署到 azure 函数后，它仍然运行该函数的旧版本。以下是 .NET core azure 函数和部署代码的构建。关于造成这种情况的原因的想法。部署过程中没有出现任何故障，只是偶尔发生。我尝试为 azure 功能添加重新启动步骤，但无济于事。作为临时解决方案，我完全删除了 azure 函数并在构建过程中重新创建它，但这不太理想。

Answer 1

可能是您的函数长时间运行。对该函数的调用将运行调用该函数时可用的代码版本。

场景1:

• T0:有电话进来，函数的 V1 开始运行
• T1:功能 V2 已部署
• T2:使用函数的 V1 完成调用

场景 2:

• T0:函数的 V1 正在运行
• T1:开始部署 V2
• T2:调用进来，因为 V2 部署尚未完成，V1 响应

如果该函数在部署几分钟后仍然以 V1 响应，则说明存在其他问题。
