WorkflowExecutionResult

描述

WorkflowExecutionResult对象提供在工作流中执行步骤的结果。

讨论

WorkflowExecutionResult 对象提供可指示步骤执行状态的返回代码。每一个步骤都有其各自的有效返回代码，并且可用来指引工作流的路径。

属性

属性	说明	数据类型
returnCode (只读)	在工作流中执行一个步骤后返回的代码。此代码可指示步骤是成功还是失败，并可用于推动工作流的执行。	Integer

代码示例

WorkflowExecutionResult 示例

以下脚本演示了如何从步骤执行过程中获得返回代码。

import arcpy, sys, traceback

#Define the callback response function. In this case it will prompt the user using the console to respond.
def callback(question, responses):

    # Print out the expected responses
    for resp in responses:
        print("[%i] %s" % (resp[1], resp[0]))
		
    # Prompt the user to respond
    val = int(input("%s - %s: " % (question[1], question[0])))
	
    # Return their response. Currently only returning the value, but could also return a note (for questions) and the name of the response
    return (val, "", "")

#Establish a connection to a Workflow database
conn = arcpy.wmx.Connect(r'c:\test\Workflow.jtc')

#Get a Job for Execution
job = conn.getJob(77601)

try:
	#Execute the current Step in the workflow
	result = job.executeStep(callback=callback)
    
	print ("Executing the first step returned %i" % result.returnCode)
	
	#Run the next Step in the workflow
        result = job.executeStep(callback=callback) 
    
	#Mark the step as complete
	job.markStepAsComplete(callback=callback) 

#Raised when a step in the workflow encounters an execution error	
except wmx.WorkflowExecutionStepError as e:
    print ("Step failed to execute:")
    print("-"*60)
    traceback.print_exc()
	
#Raised when a workflow encounters an execution error
except wmx.WorkflowExecutionError as f:
    print ("Workflow failed to execute:")
    print("-"*60)
    traceback.print_exc()
