如何将输入传递给活动

根据输入类型， ML 技能活动需要以下格式：

JSON

"this is an example of input"
"{""expected-field"":""this is another example""}"

文件

"C:/full/path/to/file.ext"

文件

"C:/full/path/to/file1.ext,C:/full/path/to/file2.ext,C:/full/path/to/file3.ext"

配置

设计器面板

Depending on the chosen Connection mode, you can configure several essential properties directly from the body of the activity.

连接模式：机器人

图 1.通过机器人建立连接模式时的“ML 技能”活动

• Search - Retrieves the list of available ML Skills and allows you to select the one to which you want to send data. This list is populated after connection.
• Item - The input that is sent alongside the ML Skill request.
• JSONResponse - The JSON response returned by the ML Skill request.

连接模式：端点

图 2. 通过端点建立连接模式时的“ML 技能”活动

• ML Skill URL - The URL of the ML Skill to used for prediction. For instance, you can type https://aicentercom/j123/invoices in the Advanced Editor. Once public, it is visible in the Dataset detail page.
• API Key - The API Key selected from the AI Center Resource. Once public, it is visible in the Dataset detail page.
• Test Skill - Test your ML Skill.
• 输入类型- 从下拉列表中选择的 ML 技能的预期输入类型（ JSON 、文件或文件）
• Item - The input that is sent alongside the ML Skill request.
• JSONResponse - The JSON response returned by the ML Skill request.

属性面板

常见

• “出错时继续”- 指定在活动引发错误时是否应继续自动化操作。该字段仅支持“布尔值”（True 和 False）。默认值为 False。因此，如果该字段为空且活动引发错误，系统将停止执行项目。如果该值设为“True”，则无论出现何种错误，系统都将继续执行项目。
  备注：

  如果“Try Catch 异常处理”中包含该活动且“出错时继续”属性的值为“True”，则系统在执行项目时不会捕获任何错误。

• DelayAfter - Delay time (in milliseconds) after executing the activity. This field supports only Int32 variables.
• DelayBefore - Delay time (in milliseconds) before the activity begins performing any operations. This field supports only Int32 variables.
• DisplayName - The display name of the activity. This field supports only String variables.
• NumberOfRetries - The maximum number of attempts to execute the ML Skill request. This field supports only Int32 variables.
• TimeoutMS - Specifies the amount of time (in milliseconds) to wait for the activity to run before an error is thrown. The default value is 30000 milliseconds (30 seconds). This field supports only Int32 variables.

输入

• API Key - The API Key of the ML Skill to be predicted. This field supports only String variables.
• Connection mode - The desired type of connection (Robot or Endpoint)
  • Robot - Deploy the ML Skill inside Robot.
  • Endpoint - Deploy the ML Skill outside Robot.
• Item - The input string that is sent alongside the ML Skill request. This field supports only strings and String variables.

其他

• “私有”- 选中后将不再以“Verbose”级别记录变量和参数的值。
• Skill URL - The URL of the ML Skill to used for prediction. This field supports only String variables.

输出

• Headers - The headers returned by the ML Skill request. This field supports only String variables.
