SharePoint 2013 Development--sharepoint Designer 2013 Workflows

?Blog Address: Http://blog.csdn.net/FoxDave

SharePoint Designer 2013 provides two modes for developers and advanced users to create custom workflows:

The text-based designer-the way we've been using it all along.

Visual designer-This requires Visio 2013.

These two modes can be toggled by clicking the View button on the menu.

SPD 2013 has new top-level containers and operations:

loops--a new top-level container, as the name implies, is used to make a set of repetitive operations, the number of cycles can be fixed or dynamically according to a certain condition to judge.

The stages--stage, the new top-level container in SPD 2013, allows you to sequentially execute groupings such as operations, conditions, and steps, and when the process controls the bottom of the stage, it passes through the go to action to other stages. With it, we can design the state machine workflow directly with SPD.

Calling SharePoint list and site WORKFLOWS--SPD 2013 enables SharePoint 2013 workflows to call lists and site workflows for SharePoint 2010. Supported by two new workflow operations (start a List Workflow and start a Site Workflow).

Call HTTP Web service--calls SOAP,WCF and OData-based services, supported by a new operation called call HTTP Web service. Requests to invoke a remote service are emitted from where the workflow is running (Windows Azure Workflow), and the return value is saved to the workflow variable and can be accessed by other operations in the workflow. The recommended implementation is to put the custom logic code in the Web service and invoke the Web service in the workflow using that action.
