PowerShell 命令

The Power Shell Command action runs a Windows PowerShell command.

You can configure the following properties for the Power Shell Command action:

操作

名称：指定操作的名称。如果需要，可以通过在字段中键入新名称来替换默认名称。
描述：用于保存操作的描述。
Run Action: 用于指定希望运行操作的频率。
- 始终：指定 Integration Service 将在每次运行集成时运行操作。
- 从不：指定 Integration Service 将不会在运行集成时运行操作。
- Conditionally, based on variable: Specifies that the Integration Service will run the action only when a selected variable meets a specified condition. 在仅有一个条件可以确定是否运行操作的情况下才可使用此选项。只要启用了此选项，就可以在提供的输入框中创建条件语句。
  
  输入框控件
  - 变量：输入希望为条件语句使用的变量。 Alternatively, you can add a variable for the conditional statement value.
  - [Relational Operator]: 指定用于条件语句的关系运算符。单击现有运算符可打开其他运算符列表，并选择一个希望使用的运算符。 For more information, refer to Relational Operators. The operators available in the list depend on whether you have selected Text or Decimal for the Type option.
  - 值： Specifies the value(s) to use for the conditional statement. Some operators, such as Is null and Is not null, do not require a value to be specified. In these situations, the Value field is not available.
  - 类型： Specifies whether the conditional statement is evaluating a text or decimal value.
- 根据表达式，在一定条件下： Specifies the conditions under which the Integration Service will run the action. 此选项在需要不只一个条件语句的情况下使用。只要启用了此选项，就可以通过创建所需的条件语句在提供的输入框中创建条件表达式。 You create and edit your conditional expression on the Tree View tab. Click the Text View tab to see a read-only text view of the conditional expression.
  
  输入框控件（“树视图”选项卡）
  - [Conditional Joiner]: 指定组中的条件语句的条件连接符。 The default conditional joiner is And.
    
    单击现有条件连接符可访问用于以以下其中一种方式配置条件表达式的菜单：
    - Select a different conditional joiner: The menu options include a list of conditional joiners. 选择希望为条件语句使用的条件连接符。 For more information about the supported conditional joiners, see Conditional Joiners.
    - Add Condition: 单击可向当前组添加其他条件语句。
    - Add Group: Click to add a sub-group of conditional statements to the current group.
    - Remove Group: 在从子组中打开菜单时，菜单中会提供此选项。单击可删除子组。
    - Clear All: 在从最顶层的组中打开菜单时，菜单中会提供此选项。单击可删除所有条件语句（包括子组）。
  - : 仅在表达式中每个条件连接符的右侧可见。单击可向与该连接符关联的组中添加条件语句。
  - : 在将光标置于现有条件语句上时可见。 Click to delete the conditional statement.
  - 变量：输入希望为条件语句使用的变量。 Alternatively, you can add a variable for the conditional statement.
  - [Relational Operator]: 指定用于条件语句的关系运算符。单击现有运算符可打开其他运算符列表，并选择一个希望使用的运算符。 For more information, refer to Relational Operators. The operators available in the list depend on whether you have selected Text or Decimal for the Type option.
  - 值： Specifies the value(s) to use for the conditional statement. Some operators, such as Is null and Is not null do not require a value to be specified. 在这些情况下，“值”字段将会被隐藏。
  - 类型： Specifies whether the conditional statement is evaluating a text or decimal value.

命令

来源：为将要发送的命令指定来源。
- 嵌入式命令：
- 变量：
  - 变量：键入指定想要为来源使用的变量。或者，可以添加一个变量。
- 外部文件：
  - 位置：指定源文件夹所在的文件系统。 File systems or locations can include local file systems or network shares, Librarian, or a supported cloud storage location. For more information about supported cloud storage locations, see Administration Console's Cloud Storage Page.
  - 文件名：指定文件路径。可以键入文件夹位置和文件名称，或单击“浏览”以找到所需的文件并选中。 Alternatively, you can add a variable to specify the desired file, or add a special character to the value you have entered.
  - 文件编码：指定源文件使用的编码。
等待命令完成： Specifies that the command is not executed until after a response is received. 否则，无需等待响应即可执行命令。
- 执行超时(秒)： Specifies the amount of time the action allows for command execution before the action times out and exits.

输出

将命令输出发送到消息日志： Logs the shell command output to the message log.

For each of the following options, you can enter the variable that you want. 或者，可以添加一个变量。

将命令输出和错误保存到变量：指定命令输出和错误将会保存到的变量。
将命令错误保存到变量：指定命令错误将会保存到的变量。
将命令异常保存到变量：指定命令异常将会保存到的变量。

测试 PowerShell 命令

测试：运行操作。 The Message pane displays information on the success or failure of the action.

Clicking the Test button executes the action only and does not run the integration. 因此，操作将会在不使用曾经可能配置为使用的集成中的任何数据的情况下运行。 For information on testing your integration, refer to Using the Test Pane.

用户帐户

Inherit from parent action: When enabled, the action inherits the user account credentials specified on the Actions property page. Alternatively, if the action is part of a Group action, it will inherit the user account credentials specified on the immediate parent Group action’s property page.
指定用户凭据：启用此选项后，会使用指定的凭据运行操作。

错误处理和诊断

Ignore errors and continue running actions: 启用此选项后，指定如果操作失败，那么会继续运行其余操作。

如果未启用此属性，并且操作失败，那么产生的行为取决于以下方案：

If you have specified Sequentially for the Execute Actions property of the selected action's hierarchical Actions or Group property page, no further actions within that group are executed.
If you have specified In Parallel for the Execute Actions property of the action's hierarchical Actions or Group property page, the actions within that same group are not affected; the errors are ignored and the other actions within the group are executed.

If the selected action is within a Group action, no actions outside of that Group action are affected.

Retry if failed: 启用此选项后，指定如果操作失败，那么 Integration Service 会尝试再次运行操作。
Maximum retries: 指定 Integration Service 将会再次尝试运行操作的最大次数。 Available when Retry if failed is enabled.
Retry interval: 指定 Integration Service 将在操作失败后，尝试再次运行操作之前等待的最大时间。 Available when Retry if failed is enabled.
