python 节俭错误 ```TSocket 读取 0 个字节 ```

Question

我的python版本:2.7.8
节俭版本:0.9.2
python-thrift 版本:0.9.2
操作系统:centOS 6.8
我的 test.thrift 文件:

const string HELLO_IN_KOREAN = "an-nyoung-ha-se-yo"
const string HELLO_IN_FRENCH = "bonjour!"
const string HELLO_IN_JAPANESE = "konichiwa!"

service HelloWorld {
  void ping(),
  string sayHello(),
  string sayMsg(1:string msg)
}

客户端.py

# -*-coding:utf-8-*-

from test import HelloWorld
from test.constants import *

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


# Make socket
transport = TSocket.TSocket('192.168.189.156', 30303)

# Buffering is critical. Raw sockets are very slow
transport = TTransport.TBufferedTransport(transport)

# Wrap in a protocol
protocol = TBinaryProtocol.TBinaryProtocol(transport)

# Create a client to use the protocol encoder
client = HelloWorld.Client(protocol)

# Connect!
transport.open()

client.ping()
print "ping()"

msg = client.sayHello()
print msg
msg = client.sayMsg(HELLO_IN_KOREAN)
print msg

transport.close()

服务器.py:

# -*-coding:utf-8-*-

from test.HelloWorld import Processor
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from thrift.server import TServer


class HelloWorldHandler(object):
    def __init__(self):
        self.log = {}

    def ping(self):
        print "ping()"

    def sayHello(self):
        print "sayHello()"
        return "say hello from 156"

    def sayMsg(self, msg):
        print "sayMsg(" + msg + ")"
        return "say " + msg + " from 156"


handler = HelloWorldHandler()
processor = Processor(handler)
transport = TSocket.TServerSocket("192.168.189.156", 30303)
tfactory = TTransport.TBufferedTransportFactory()
pfactory = TBinaryProtocol.TBinaryProtocolFactory()

server = TServer.TThreadPoolServer(processor, transport, tfactory, pfactory)

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

我的错误:

ping()

    msg = client.sayHello()

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

Answer 1

我想这个问题很老了，但我遇到了同样的错误信息。原来是服务器端有错别字。 thrift 库试图使用 Python 日志记录消息，但我没有设置日志记录，所以它只是说，“找不到记录器“thrift.server.TServer”的处理程序”。

当我做了一些最小的日志记录时，(将这段代码添加到服务器端):

import logging
logging.basicConfig(level=logging.DEBUG)

日志显示了我在 Python 堆栈跟踪中的拼写错误，我修复了它并且它再次起作用。 “TSocket read 0 bytes”错误意味着服务器发生异常并且没有写出消息。
