来自onvif的方法产生"AnySimpleType.pytonvalue() not implemented“

Question

当我试图从我的IP摄像头获取ONVIF格式的实况流时，我使用了streaming.py (https://github.com/FalkTannhaeuser/python-onvif-zeep)。

不幸的是，我得到的错误是"AnySimpleType.pytonvalue()没有实现“。我还可以通过使用以下命令获得最新的zeep实现

pip install --upgrade onvif_zeep

我不知道为什么示例代码中的方法没有实现。下面是完整的代码：

    from onvif import ONVIFCamera

def media_profile_configuration():
    '''
    A media profile consists of configuration entities such as video/audio
    source configuration, video/audio encoder configuration,
    or PTZ configuration. This use case describes how to change one
    configuration entity which has been already added to the media profile.
    '''

    # Create the media service
    mycam = ONVIFCamera('****', ****, '****', '****')
    media_service = mycam.create_media_service()

    profiles = media_service.GetProfiles()

    # Use the first profile and Profiles have at least one
    token = profiles[0]._token

    # Get all video encoder configurations
    configurations_list = media_service.GetVideoEncoderConfigurations()

    # Use the first profile and Profiles have at least one
    video_encoder_configuration = configurations_list[0]

    # Get video encoder configuration options
    options = media_service.GetVideoEncoderConfigurationOptions({'ProfileToken':token})

    # Setup stream configuration
    video_encoder_configuration.Encoding = 'H264'
    # Setup Resolution
    video_encoder_configuration.Resolution.Width = \
                    options.H264.ResolutionsAvailable[0].Width
    video_encoder_configuration.Resolution.Height = \
                    options.H264.ResolutionsAvailable[0].Height
    # Setup Quality
    video_encoder_configuration.Quality = options.QualityRange.Min
    # Setup FramRate
    video_encoder_configuration.RateControl.FrameRateLimit = \
                                    options.H264.FrameRateRange.Min
    # Setup EncodingInterval
    video_encoder_configuration.RateControl.EncodingInterval = \
                                    options.H264.EncodingIntervalRange.Min
    # Setup Bitrate
    video_encoder_configuration.RateControl.BitrateLimit = \
                            options.Extension.H264[0].BitrateRange[0].Min[0]

    # Create request type instance
    request = media_service.create_type('SetVideoEncoderConfiguration')
    request.Configuration = video_encoder_configuration
    # ForcePersistence is obsolete and should always be assumed to be True
    request.ForcePersistence = True

    # Set the video encoder configuration
    media_service.SetVideoEncoderConfiguration(request)

if __name__ == '__main__':
    media_profile_configuration()

有人知道为什么我不能访问配置摄像头的方法吗？

基于OP对他的问题的评论，以及试验和错误，我设法修复了这个错误。

在您的.py中，添加以下代码：

import zeep

def zeep_pythonvalue(self,xmlvalue):
    return xmlvalue

zeep.xsd.AnySimpleType.pythonvalue = zeep_pythonvalue
