主流PRC框架 thrift(其二)

Apache Thrift　是主流的PRC框架之一
    1,最初是由 facebook 实现的一种支持多种编程语言的，高效的远程服务器框架
    2,它采用中间语言(IDL,接口描述语言)，定义PRC接口和数据类型,通过编译器生成不同的代码（python,java,C++,Ruby）等
    3,其传输数据采用的是二进制数据.相对于XML与JSON体积更小，相对于高并发更加具优势
一,安装　thrift

sudo apt-get install libboost-dev libboost-test-dev libboost-program-options-dev libevent-dev automake libtool flex bison pkg-config g++ libssl-dev

下载/安装 thrift 软件

wget http://mirrors.hust.edu.cn/apache/thrift/0.11.0/thrift-0.11.0.tar.gz
tar zxf thrift-0.11.0.tar.gz
cd thrift-0.11.0/
make && sudo make install # 编译与安装！
thrift -version # 产看是否安装成功

新建文件 demo_thrift.thrift

service HelloWhat{
    string hello_x(1:string what)
}

命令行 生成　thrift 项目

thrift --gen py demo_thrift.thrift

编辑client.py

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

from demo_thrift.demo.HelloWhat import *

def run():
    try:
        transport = TSocket.TSocket('localhost',9234)
        # 选择 传输层!
        transport = TTransport.TBufferedTransport(transport)
        # 选择一个协议！ 与上都要与服务器保持相同！
        protocol = TBinaryProtocol.TBinaryProtocol(transport)
        client = Client(protocol)
        transport.open()
        res = client.hello_x("Thrift")
        res_second = client.hello_x("thrift again")
        print(res_second)
        print(res)
        # 只要没有关闭　可以随时调用多次　client.hello_x()
        transport.close()
    except Exception as e:
        print(e)

if __name__ == '__main__':
    run()

编辑server.py

from thrift.protocol import TBinaryProtocol
from thrift.server import TServer
from thrift.transport import TSocket
from demo_thrift.demo.HelloWhat import *

class HelloHander:
     def hello_x(self,what):
      print('hello_x was called!')
      return "hello %s!"%what

def run():
    header =HelloHander()
    pross = Processor(header)
    # 监听端口
    tran = TSocket.TServerSocket('localhost', 9234)
    # 选择传输层
    tfac = TTransport.TBufferedTransportFactory()
    # 选择传输层协议
    pfactory = TBinaryProtocol.TBinaryProtocolFactory()
    server = TServer.TThreadPoolServer(
      pross,tran,tfac,pfactory
    )
    server.setNumThreads(5)
    print('server is begin')
    server.serve()
if __name__ == '__main__':
    run()

运行 server.py 运行　client.py
