推荐答案

使用powershell调用api不需要那么复杂。我们内置的功能可以满足您的要求。由于发布管道包含一个或多个阶段，因此重新部署发布管道可以视为重新运行阶段。

No need to be so complicated to use powershell to call api. We have built-in feature can achieve your requirement. Since release pipeline consists of one or more stages，re-deploy release pipeline can be considered as re-running stages.

因此，请首先打开发布管道定义。然后导航到阶段的部署后条件 =>启用自动重新部署触发器 =>选择事件和动作：

So open the release pipeline definition first. Then navigate to Post-deployment conditions of the stage => Enable Auto-redeploy trigger => Select the Event and the action:

查看实际执行结果：

这是Azure Devops的优势，因此您不必担心在Prod部署期间是否会出问题，因为该工具将自动通过其自身自动撤消上一次成功的部署。

This is the advantage of the Azure Devops so that you don't need to worry if some thing goes wrong during the Prod deployments as the tool will automatically reverse the last successful deployment by its own.
