Python Zeep-“输入字符串的格式不正确”

Question

我正在使用 zeep 与 Python 中的 Web 服务交互；我的一切都基本正常，但在设置某些字段时遇到困难。问题似乎与输入字符串有关，它尝试将其转换为“文本”但失败。我有点迷失，不知道如何实现这一点，到目前为止我还没有运气。我假设我必须进行某种转换，但我不确定如何做到这一点。

对于上下文，这就是我想要设置的。已找到字段（本例中为优惠券 ID），但 FieldValue 的格式不正确。这是该代码的概要。

        #Set fields
        voucher_id.FieldId = 15   #Voucher ID
        voucher_id.FieldValue = "test"

        #Array
        field_array =  factory.ArrayOfFieldWithValue()
        field_array['FieldWithValue'].append(voucher_id)

        #Call service function to add document info, which causes the exception

这里是异常消息。

我尝试以其他几种基本方式格式化 FieldValue，但总是收到相同的错误。

通过使用zeep.xsd.AnyObject将Python类型转换为xsd类型解决。

voucher_id.FieldValue = zeep.xsd.AnyObject(zeep.xsd.String(), 'zeep_test')
