是否可以使用Blackboard WebServices以编程方式向Blackboard提交作业

Question

是否有人可以确认是否可以使用Blackboard WebServices以编程方式向Blackboard提交作业？(如文档here所示。具体来说，我想知道使用Gradebook.WS、AttemptVO和studentSubmission方法提交作业的正确方式。这是我到目前为止已经尝试过的，主要是在Bb成绩册中可以看到的尝试，除了在黑板成绩册中看不到attemptVO.studentSubmission：

from suds.client import Client 
from suds.plugin import MessagePlugin 
from suds.wsse import Timestamp, UsernameToken, Security 

WS_BASE_URL = 'http://bbdev.bangor.ac.uk/webapps/ws/services/' 

class Learn9Plugin(MessagePlugin): 
    def marshalled(self, context): 
        password = context.envelope.childAtPath('Header/Security/UsernameToken/Password') 
        password.set('Type', 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText') 

security = Security() 
security.tokens.append(Timestamp()) 
security.tokens.append(UsernameToken('session', 'nosession')) 
plugin = Learn9Plugin() 

context = Client(   WS_BASE_URL + 'Context.WS?wsdl', 
location = WS_BASE_URL + 'Context.WS', 
autoblend = True, 
wsse = security, 
plugins = [plugin]) 

context.options.wsse.tokens[1].password = context.service.initialize() 

result = context.service.loginTool('xxxxx', 'xxxx', 'xxxxx', '', 500) 

course_id = '_15877_1' 

gradebook = Client(WS_BASE_URL + 'Gradebook.WS?wsdl', 
    location=WS_BASE_URL + 'Gradebook.WS', 
    autoblend=True, 
    wsse=security, 
    plugins=[plugin]) 


attemptVO = gradebook.factory.create('ns0:AttemptVO') 

attemptVO.override = False 
attemptVO.publicFeedbackToUser = False 
attemptVO.score = 0 
attemptVO.gradeId = '_169_1' # Smith
attemptVO.studentSubmission = 'Some sample text representing an assignment'
attemptVO.studentSubmissionTextType = 'PLAIN_TEXT'
print attemptVO
attempt_result = gradebook.service.saveAttempts(course_id, [attemptVO,])
print attempt_result

结果：

(AttemptVO){
   attemptDate = None
   creationDate = None
   displayGrade = None
   exempt = None
   expansionData[] = <empty>
   feedbackToUser = None
   grade = None
   gradeId = "_169_1"
   groupAttemptId = None
   id = None
   instructorNotes = None
   override = False
   publicFeedbackToUser = False
   score = 0
   status = None
   studentComments = None
   studentSubmission = "Some sample text representing an assignment"
   studentSubmissionTextType = "PLAIN_TEXT"
 }

非常感谢。

Blackboard的一位开发人员回复我说，因为'studentSubmission‘和'setStudentSubmissionTextType’方法都是只读属性，所以不能使用webservice提交作业。

已向Blackboard提出更新文档的请求。
