Question

我的相机每5秒向我的计算机端口80发送一个带有HTTP的protobuf。我正在尝试解码protobuf消息，但它提供了google.protobuf.message.DecodeError：解析消息错误＆＃39;在ParseFromString（）方法中。我创建了pb2文件，打开端口，然后检查帖子是否即将发布。我相信错误的原因是我将消息读作原始而不是二进制，但我找不到任何解决方案来读取二进制或将文本转换为正确的格式。这是我的代码：

from http.server import BaseHTTPRequestHandler, HTTPServer
import logging
import DevicesFrame_pb2

class S( BaseHTTPRequestHandler ):
    def _set_response( self ):
        self.send_response( 200 )
        self.send_header( 'Content-type', 'application/octet-stream' )
        self.end_headers( )

    def do_POST( self ):
        content_length = int( self.headers['Content-Length'] )
        post_data = self.rfile.read( content_length )
        devices_frame = DevicesFrame_pb2.Device( )

        #Code works fine until here. Gives the error to this line
        devices_frame.ParseFromString( post_data )

        print( MessageToString( devices_frame ) )

        self._set_response( )

def run( server_class = HTTPServer, handler_class = S, port = 80):
    logging.basicConfig( level = logging.INFO )
    server_address = ( '', port )
    httpd = server_class( server_address, handler_class )
    logging.info( 'Starting httpd....\n' )

    try:
        httpd.serve_forever( )
    except KeyboardInterrupt( ):
        pass

    httpd.server_close( )
    logging.info( 'Stopping httpd...\n' )    

if __name__ == '__main__':
    run( )

google.protobuf.message.DecodeError：在Python3中解析HTTP消息正文的消息时出错
