VSTS部署IIS应用程序winrm并更改appsettings.json [英] VSTS Deploy IIS App winrm and change appsettings.json

问题描述

我正在使用部署IIS应用程序Winrm"任务在另一台计算机上部署IIS应用程序.

I am deploying an IIS app on another machine using the "Deploy IIS App winrm" task.

此任务将部署zip文件.在此zip文件中，有一个appsettings.json文件，其变量以下划线开头和结尾.

This task deploys the zip file. In this zip there is an appsettings.json with variables preceding and ending with underscores.

我需要为每个环境替换appsettings.json中的值. 我尝试将json文件放置为"Web部署参数文件"和覆盖参数"，但这不起作用.如何更改appsettings.json?

I need to replace values in the appsettings.json for each environment. I tried putting the json file as "Web deploy parameter file" and "Overide parameters" but this doesn't work. How can I change the appsettings.json?

推荐答案

您无需更改appsettings.json.核心项目可以从每个环境变量ASPNETCORE_ENVIRONMENT的appsettings.[environment].json文件中检索数据.

You don’t need to change appsettings.json. The core project can retrieve data from appsettings.[environment].json file per to ASPNETCORE_ENVIRONMENT environment variable.

例如:

1. 将相应的appsettings.[environment].json文件(例如appsettings.Production.json，appsettings.Development.json)添加到项目中，并在每个文件中设置相应的值.
2. 启动文件中的代码

1. Add corresponding appsettings.[environment].json files to project, such as appsettings.Production.json, appsettings.Development.json and set the corresponding value in each files.
2. Code in Startup file

:

  public Startup(IHostingEnvironment env)
        {
            var builder = new ConfigurationBuilder()
                .SetBasePath(env.ContentRootPath)
                .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
                .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
                .AddEnvironmentVariables();
            Configuration = builder.Build();
        }

1. 为每台环境计算机设置/添加ASPNETCORE_ENVIRONMEN T环境变量(只需设置/添加一次)

1. Set/add ASPNETCORE_ENVIRONMENT environment variable to each environment machine (just need to set/add once)

如果您仍然想更改appsettings.json文件，则可以解压缩打包的文件，然后使用令牌任务(例如

If you still want to change appsettings.json file, you can unzip packaged file, then update file by using Token task (e.g. Replace Tokens), then zip these files.
