我一直在阅读有关 protobuf-net 的内容,这太棒了!
一般来说,它工作得很好。但是我遇到了一些问题。
我正在尝试使用 protobuf 在 Python 和 C# 之间编写通信代码。
.proto 如下:
message GetAllCalculate{
required string agentID=1;
}
message CalculateInfo{
required string CalStarttime=1;
optional string CalEndtime=2;
required string Smiles=3;
optional string CAS=4;
optional string ChName=5;
optional string EnName=6;
required string Param=7;
required string Result=8;
required bool IsFinished=9;
}
message GetAllCalulateResponse{
required bool isSuccessful = 1;
required int32 Count=2;
repeated CalculateInfo History=3;
}
在 Python 客户端中,代码如下:
msg_resp = GetAllCalulateResponse()
calculateInfo = [None] * 2
cnt = 0
for result in resultSets: #resultSets can read from other place,like database
calculateInfo[cnt] = msg_resp.History.add()
calculateInfo[cnt].CalStarttime = str(result.calculateStartTime)
calculateInfo[cnt].CalEndtime = result.calculateEndTime.strftime('%Y-%m-%d %X')
calculateInfo[cnt].IsFinished = result.isFinished
calculateInfo[cnt].Param = result.paramInfo
**calculateInfo[cnt].Result = str('ff'*50) #result.result**
calculateInfo[cnt].Smiles = result.smilesInfo.smilesInfo
calculateInfo[cnt].CAS = result.smilesInfo.casInfo
nameSets = CompoundName.objects.filter(simlesInfo=result.smilesInfo.pk,isDefault=True)
for nameSet in nameSets:
if nameSet.languageID.languageStr == Chinese_Name_Label:
calculateInfo[cnt].ChName = nameSet.nameStr
elif nameSet.languageID.languageStr == English_Name_Label:
calculateInfo[cnt].EnName = nameSet.nameStr
cnt = cnt +1
C# 代码(使用 Protobuf-net):
string retString = HTTPPost2UTF8(bytes, GetAllCalculateHandlerAPI); //Get from Python Clint
bytesOut = System.Text.Encoding.UTF8.GetBytes(retString);
MemoryStream streamOut = new MemoryStream(bytesOut);
GetAllCalulateResponse response = Serializer.Deserialize <GetAllCalulateResponse>(streamOut);
但是当我**calculateInfo[cnt].Result = str('ff'*50) #result.result**
做大时,比如 str('ff') * 5000,C# 客户端会抛出 OverFlowException。当我设置它 str('ff') * 100 时,它会抛出 EndOfStreamException。
如何解决这个问题?提前致谢!
