解析Windows批处理文件的输出以在下一个批处理文件命令中使用

Question

我正在做一些Windows批处理文件“编程”，以使用亚马逊网络服务CodeDeploy注册应用程序版本。

以下是到目前为止我的批处理文件中的内容：

@echo off
aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1.zip --source .\ --description "Application Revision Pushed from Tst"

当我运行该命令时：

aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1 --source .\ --description "Application Revision Pushed from Tst"

..。就其本身而言，上述命令的输出将显示在命令提示符中：

To deploy with this revision, run:
aws deploy create-deployment --application-name MyApp1 --s3-location bucket=s3-codeDevel-MyApp1,key=MyApp1.zip,bundleType=zip,eTag=f4f28724b951fdeeee61d57c24ceba99 --deployment-group-name <deployment-group-name> --deployment-config-name <deployment-config-name> --description <description>

我想在批处理文件中运行另一个命令，该命令在下一个命令中解析并使用上面的输出，因为"eTag“的值发生了变化。

最后，我希望我的批处理文件是这样的：

@echo off
aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1.zip --source .\ --description "Application Revision Pushed from Tst"
aws deploy create-deployment --application-name MyApp1 --s3-location bucket=s3-codeDevel-MyApp1,key=MyApp1.zip,bundleType=zip,eTag=<Parsed from previous command> --deployment-group-name DeploymentGroup --deployment-config-name DeploymentConfigName --description "My Description"

我该怎么做呢？

Answer 1

几个技巧的混合：

• 运行命令并捕获输出中的最后一行
• remove all直到来自“
• ”的第一个单词-使用该值

执行命令

@echo off
set "command=aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1 --source .\ --description "Application Revision Pushed from Tst""
for /f "delims=" %%a in ('%command%') do set "line=%%a"
set "line=%line:*eTag=%"
for /f "delims== " %%a in ("%line%") do set "key=%%a"
echo Debug: Key=%key%
aws deploy create-deployment --application-name MyApp1 --s3-location bucket=s3-codeDevel-MyApp1,key=MyApp1.zip,bundleType=zip,eTag=%key% --deployment-group-name DeploymentGroup --deployment-config-name DeploymentConfigName --description "My Description"
