场景

Thrift介绍以及Java中使用Thrift实现RPC示例：

namespace java thrift.generated

typedef i16 short
typedef i32 int
typedef i64 long
typedef bool boolean
typedef string String

struct Person {
    1:optional String username,
    2:optional int age,
    3:optional boolean married
}

exception DataException {
    1:optional String message,
    2:optional String callback,
    3:optional String date
}

service PersonService {
    Person getPersonByUsername(1:required String username) throws (1:DataException dataException),
    void savePerson(1:required Person person) throws(1:DataException dataException)
}

为了能生成代码，添加一个py的namespace

namespace py py.thrift.generated

添加之后的完成代码

namespace java thrift.generated
namespace py py.thrift.generated

typedef i16 short
typedef i32 int
typedef i64 long
typedef bool boolean
typedef string String

struct Person {
    1:optional String username,
    2:optional int age,
    3:optional boolean married
}

exception DataException {
    1:optional String message,
    2:optional String callback,
    3:optional String date
}

service PersonService {
    Person getPersonByUsername(1:required String username) throws (1:DataException dataException),
    void savePerson(1:required Person person) throws(1:DataException dataException)
}

之前已经将thrift的编译器添加进环境变量，所以在IDEA中的Ternimal中使用其生成Python代码

thrift --gen py src/thrift/MyData.thrift

后面跟的是thrift文件的位置

此时会在项目根目录下生成gen-py目录，里面就是生成的python代码

新建Python项目PyThrift，这里使用PyCharm再打开Ternimal,使用pip安装thrift

pip install thrift

然后将上面生成的python代码的gen-py下面的py目录和__init_.py复制到Pycharm中的Python项目中

Python客户端请求Java服务端

在Python项目中新建py_client.py

# -*- coding:utf-8 -*-
__author__='公众号:霸道的程序猿'

from py.thrift.generated import PersonService
from py.thrift.generated import ttypes
from thrift import Thrift
from thrift.transport import TSocket
from thrift. transport import TTransport
from thrift. protocol import TCompactProtocol

try:
    tSocket = TSocket.TSocket('localhost',8899)
    tSocket.setTimeout(600)
    transport = TTransport.TFramedTransport(tSocket)
    protocol = TCompactProtocol.TCompactProtocol(transport)
    client = PersonService.Client(protocol)

    transport.open()

    person = client.getPersonByUsername("公众号:霸道的程序猿")

    print (person.username)
    print (person.age)
    print(person.married)

    print('--------------------')

    newPerson = ttypes.Person()
    newPerson.username('公众号:霸道的程序猿')
    newPerson.age = 50
    newPerson.married = True

    client.savePerson(newPerson)

    transport.close()

except Thrift.TException as tx:
    print(tx.message)

注意这里的Python客户端所使用的通信层和传输层的协议要和上面博客中Java客户端使用的一致。

然后运行Java中的服务端，以及Python中的客户端

可以看到Python的客户端调用了Java服务端的两个方法成功。

Java客户端调用Python服务端

在Python项目中新建PersonServiceImpl.py作用与之前Java服务端的实现类相同都是实现

thrift中struct中定义的接口方法。

# -*- coding:utf-8 -*-
__author__='公众号:霸道的程序猿'

from py.thrift.generated import ttypes

class PersonServiceImpl:
    def getPersonByUsername(self,username):
        print('Python 服务端获取到客户端传来的参数:'+username)

        person = ttypes.Person()
        person.username = username
        person.age = 50
        person.married = True
        return  person
    def savePerson(self,person):
        print('Python 服务端获取客户端的参数:')

        print(person.username)
        print(person.age)
        print(person.married)

然后再新建服务端py_server.py

# -*- coding:utf-8 -*-
__author__='公众号:霸道的程序猿'

from py.thrift.generated import PersonService
from PersonServiceImpl import PersonServiceImpl
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import  TCompactProtocol
from thrift.server import TServer

try:
    personServiceHandler = PersonServiceImpl()
    processor = PersonService.Processor(personServiceHandler)

    serverSocket = TSocket.TServerSocket(host='127.0.0.1',port=8899)
    transportFactory = TTransport.TFramedTransportFactory()
    protocolFactory = TCompactProtocol.TCompactProtocolFactory()

    server = TServer.TSimpleServer(processor,serverSocket,transportFactory,protocolFactory)
    server.serve()

except Thrift.TException as ex:
    print(ex.message)

注意这里的TServerSocket中的参数不仅要有端口还要有port，并且这里的host如果设置localhost的话

会提示拒绝连接，所以这使用的是127.0.0.1

运行Python的服务端，然后再运行Java的客户端

在Java客户端中调用Python服务端的方法成功。
