分词器任务，它是 Release Management Utility Tasks 允许根据环境转换配置文件.

The tokenizer task which comes as a part of Release Management Utility Tasks allows to transform config files depending upon the environment.

可以使用包含所有环境的所有配置的单个 JSON 配置文件，任务将根据环境自动选择正确的配置.

A single JSON config file containing all the configuration for all the environments can be used and the task will automatically pick up the right configuration depending upon the environment.

{
  "<environment>": {
    "CustomVariables": {
    "Variable1": "value1",
    "Variable2": "value2",
  },
    "ConfigChanges": [
        {
          "KeyName": "/configuration/appSettings/add[@key='ServiceURL']",
          "Attribute":"value",
          "Value":"https://ServiceURL"
        },
        {
          "KeyName": "/configuration/appSettings/add[@key='EnableDebugging']",
          "Attribute":"value",
          "Value":"false"
        },
        {
          "KeyName":"/configuration/connectionStrings/add[@name='databaseentities']",
          "Attribute": "connectionString",
          "value": "Integrated Security=True;Persist Security Info=False;Initial Catalog=DB;Data Source=servername"
        }
    ]
}

这样，您可以在单个 JSON 文件中拥有多个环境及其配置，并且标记生成器任务将根据部署进行的环境修改您的配置.

Like this you can have many environments and their configuration in a single JSON file and the tokenizer task will modify your config depending upon the environment on which the deployment is going on.
