我需要在我的 python - tornado 服务器上接收协议缓冲区消息并从二进制消息中获取内容。
postContent = self.request.body
message = prototemp.ReqMessage()
message.ParseFromString(postContent)
使用测试工具可以完美运行。当我在沙盒环境中运行它并模拟来自我的客户端的 1000 个请求时,它在某些情况下有效,但在大多数请求中,它会引发异常 -
File "server1.py", line 21, in post
message.ParseFromString(postContent)
File "/usr/lib/python2.6/site-packages/protobuf-2.4.1-py2.6.egg/google/protobuf/message.py", line 179, in ParseFromString
self.MergeFromString(serialized)
File "/usr/lib/python2.6/site-packages/protobuf-2.4.1-py2.6.egg/google/protobuf/internal/python_message.py", line 755, in MergeFromString
if self._InternalParse(serialized, 0, length) != length:
File "/usr/lib/python2.6/site-packages/protobuf-2.4.1-py2.6.egg/google/protobuf/internal/python_message.py", line 782, in InternalParse
pos = field_decoder(buffer, new_pos, end, self, field_dict)
File "/usr/lib/python2.6/site-packages/protobuf-2.4.1-py2.6.egg/google/protobuf/internal/decoder.py", line 544, in DecodeField
if value._InternalParse(buffer, pos, new_pos) != new_pos:
File "/usr/lib/python2.6/site-packages/protobuf-2.4.1-py2.6.egg/google/protobuf/internal/python_message.py", line 782, in InternalParse
pos = field_decoder(buffer, new_pos, end, self, field_dict)
File "/usr/lib/python2.6/site-packages/protobuf-2.4.1-py2.6.egg/google/protobuf/internal/decoder.py", line 410, in DecodeField
field_dict[key] = local_unicode(buffer[pos:new_pos], 'utf-8')
UnicodeDecodeError: 'utf8' codec can't decode byte 0xce in position 1: invalid continuation byte
在其他一些情况下,它会给出这些错误 -
UnicodeDecodeError: 'utf8' codec can't decode byte 0xbf in position 3: invalid start byte
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe7 in position 3: unexpected end of data
可能是什么原因 ?
