TSocket read 0 bytes Apache Thrift MongoDB

问题

I am developing a small application with RPC framework Apache Thrift and Python. I want to use MongoDB. I am using mongoengine connector and I defined thrift data model and generated code from it

When storing tags in a list in the server all is fine. However, I get errors when trying to store tags in database

Here Is my code

server.py

import os
import sys

from mongoengine import *

sys.path.append(os.path.join(
    os.path.dirname(os.path.abspath(__file__)), 'gen-py'))

from thrift.transport import TSocket, TTransport
from thrift.protocol import TBinaryProtocol
from thrift.server import TServer

from tag import *


class Tag(Document):
      identifier = LongField()
      description = StringField()

class TagHandler(object):

    #def __init__(self):
        #self.tags = []

    def createTag(self, identifier, description):
    tag = Tag(identifier=identifier, description=description).save()
        #self.tags.append(tag)
        return tag


connect("tags", host="127.0.0.1")
handler = TagHandler()
processor = TagService.Processor(handler)
transport = TSocket.TServerSocket('127.0.0.1', 9090)
tfactory = TTransport.TBufferedTransportFactory()
pfactory = TBinaryProtocol.TBinaryProtocolFactory()
server = TServer.TSimpleServer(processor, transport, tfactory, pfactory)

print "Starting python server..."
server.serve()

tag.thrift

exception TagException {

    1: string Reason
}



service TagService {

    i64 createTag(1: i64 identifier, 2: string description) throws (1:TagException e)


}

client.py

host = '127.0.0.1'
port = 9090

import sys
import os

sys.path.append(os.path.join(
    os.path.dirname(os.path.abspath(__file__)), 'gen-py'))

from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol

from tag import *




transport = TSocket.TSocket( host , port)
transport = TTransport.TBufferedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = TagService.Client(protocol)
transport.open()
result = client.createTag(12345, "dirty creation")    
print ("success")
transport.close()

When executing this, I get

thrift.transport.TTransport.TTransportException: TSocket read 0 bytes

in the client and

No handlers could be found for logger "thrift.server.TServer"

in the server

Any help will be highly appreciated

回答1:

You should be careful with your :

i64 createTag(1: i64 identifier, 2: string description) throws (1:TagException e)

Should be better :

void createTag(1: i64 identifier, 2: string description) throws (1:TagException e)

Care, you have to be ok with that until next Tuesday. lol.
