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)
}

client.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()

server.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()

  File "client.py", line 29, in <module>
    msg = client.sayHello()
  File "/home/zhihao/bfd_mf_report_warning_service/local_test/test/HelloWorld.py", line 68, in sayHello

Answer 1

我猜这个问题已经过时了，但是我遇到了同样的错误信息。事实证明，服务器端存在拼写错误。 thrift库试图使用Python日志记录来记录消息，但是我没有设置日志记录，所以它只是说，＆＃34;没有为logger找到处理程序＆＃34; thrift.server.TServer＆＃ 34;＆＃34;

当我做一些最小的日志记录时，（将此代码添加到服务器端）：

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

日志记录向我展示了Python堆栈跟踪中的错字，我修复了它并再次起作用。＆＃34; TSocket读取0字节＆＃34;错误意味着服务器出现异常并且没有写出消息。

Answer 2

我的操作系统环境问题我将端口30303更改为9999，它已成功运行。

Answer 3

当你启动thrift服务时，你需要设置协议，如：./ hbase-daemon.sh start thrift -c compact protocol; 在你的代码中，你需要set protocol ='compact'，比如thie：con = happybase.Connection（host ='localhost'，port =你的thriftport，autoconnect = True，protocol ='compact'，timeout = xxx）

Answer 4

我遇到这个问题是因为我的实现提出了一个异常，即未指定要引发服务端点，我通过在端点规范的末尾添加throws ( 1: MyException exc)来解决此问题。

python thrift错误```TSocket读取0字节```
