python调用webservice接口字典问题

Question

1、我在使用suds库去掉用web service接口时候的语法问题？

2、下图是接口文档

3、这是我调用时所写的代码

4、当我运行的时候抱错误：

  File "import.py", line 8, in <module>
    res = client.service['ISysSynchroGetOrgWebServicePort'].getUpdatedElements(t).message

    raise TypeNotFound(content.tag)
suds.TypeNotFound: Type not found: 'type'

5、我初步理解是因为字典内有嵌套字典，不知道理解的对不对，如果把"returnOrgType": [{"type": "person", "type": "dept"}]这段去掉程序是可以运行的，然而接口文档也说明是必须要用这样的格式来获取相关的字段，请问这个问题该如何解决呢 ？

Answer 1

不写了是 json 么。

json.dumps([{'type': 'a'}, {'type': 'b'}])
