我一直在阅读有关protobuf-net的内容,这太棒了!
总的来说,它完美无缺。但我遇到了一些问题。
我正在尝试使用protobuf在Python和C#之间编写通信代码。
.proto unders:
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);
但是当我使**calculateInfo[cnt].Result = str('ff'*50) #result.result**
变大时,就像str('ff')* 5000一样,C#客户端将抛出OverFlowException。当我将它设置为str('ff')* 100时,它将抛出EndOfStreamException。
怎样才能解决这个问题?提前谢谢!
答案 0 :(得分:2)
这令我担心:
string retString = HTTPPost2UTF8(bytes, GetAllCalculateHandlerAPI); //Get from Python
bytesOut = System.Text.Encoding.UTF8.GetBytes(retString);
MemoryStream streamOut = new MemoryStream(bytesOut);
protobuf数据不是文本,并且确定不是UTF8。没有有效的方法可以将protobuf二进制文件作为UTF8传递而不会破坏它。选项:
