是否可以在发布后脚本中使用带双引号的命令参数？

Question

I want to call a command in a postpublish script for my ASP.NET Core project. The command requires an argument that contains spaces and is wrapped in " . Below is the desired command that I would run, this works when running manually from the command line:

dotnet nswag webapi2swagger /Assembly:./path/to/assembly.dll /Output:./path/to/swagger.json /InfoTitle:"My API Name" /InfoVersion:v1

In my project.json this command is wrapped in a JSON string. In order to use quotes in the string I escape them with \\ :

"dotnet nswag webapi2swagger /Assembly:%publish:OutputPath%/assembly.dll /Output:%publish:OutputPath%/docs/swagger.json /InfoTitle:\\"My API\\" /InfoVersion:v1"

Unfortunately, while this creates a valid JSON string, the command that runs at post publish appears to actually resolve the escape characters. As a result the value passed to InfoTitle is \\"My and not "My API" like I would expect.

Is this a bug? Is it possible to somehow escape quotes differently in a postpublish script in order to get the results I expect?

Answer 1

I had a similar problem where I needed to run a command on postPublish but got the message "No executable found matching command "cmd.exe"" when publishing within VS2015.

What I ended up doing is to create a postPublish.cmd file in the project root and configuring it to run on postPublish in project.json, passing the publish output folder to the script.

    "postpublish": [
        "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%",
        "postPublish.cmd %publish:OutputPath%",
    ]

You will have more control inside the postPublish.cmd script and do not need to escape "path"'s, eg:

:: use %1 to access the temp publish folder:
rmdir /s /q "%1\wwwroot\Uploads"

:: The script will be executed at the root of your project. Testing this:
cd >> test.txt
type "project.json" >> testing2.txt
