• 您可以启用或禁用出厂设置 ThingWorx Flow 连接器的“复制”操作。
 |
默认情况下，以下连接器不支持“复制”操作：Azure、Dynamics 365 CRM、Excel Online、FTP、Integrity Lifecycle Manager、OData、FactoryTalk MOM、SAP、SOAP、“SQL 连接器”、Swagger、ThingWorx、Twilio、Windchill、Zendesk
即使对 settings.json 文件进行修改以允许对连接器进行“复制”操作，这些操作也不会生效。

要更新 ThingWorx Flow 服务器上自定义操作的 settings.json 文件，请执行以下操作：
1. 运行以下命令以从 ThingWorx Flow 实例下载配置设置：
flow-deploy settings download -f <Path_to_Customization_File> -t <ThingWorx_Base_URL> -u <ThingWorx_Administrator_Username> -p '<ThingWorx_Administrator_Password>' -c devtools -s default
此命令会将配置文件下载到您在命令中使用 -f 自变量指定的位置。
◦ 要将内部节点模块列入白名单，请修改 settings.json 文件中的 whiteListBuiltInModules 部分。
◦ 要将外部节点模块列入白名单，请修改 settings.json 文件中的 whiteListExternalModules 部分。
◦ 要对任何连接器允许或禁止“复制”操作，请修改 settings.json 文件中的 copyProhibitedConnectors 部分。
3. 运行以下命令以将配置设置上载到 ThingWorx Flow 实例：
flow-deploy settings upload -f <Path_to_Customization_File> -t <ThingWorx_Base_URL> -u <ThingWorx_Administrator_Username> -p '<ThingWorx_Administrator_Password>' -c devtools -s default
此命令会从您在命令中使用 -f 自变量指定的位置上载配置文件。
此文件上载成功后，您可以在创建自定义操作时使用这些自定义。
