php通过ice通信引擎调用python服务

而温柔

PHP调用python，有很多种方式，查阅了下，大致有以下方式：


system、exec、shell_exec、passthru
popen、proc_open
socket
ppython
PHPRPC
pip(python in php)
XMLRPC、jsonrpc

当然，还有ice这种通信组件，今天配置了下ice、然后运行了简单的php和python通信、python和python通信的示例程序。

下载和安装参见http://www.zeroc.com/download.html的Packages for Ubuntu 13.04 (Raring Ringtail) and 14.04 (Trusty Tahr)和Install instructions for Ubuntu 13.04 (Raring Ringtail)两部分，安装过程只碰到一个问题：E: Unable to locate package db5.3-utils，后来发现是程序包名错了，应该是db5.3-util

用python写服务端和客户端程序，通过ice进行通信
——————————————————————————
1、Writing a Slice Definition:hello.ice


module Demo {
    interface Printer {
        void printString(string s);
    };
};
2、Compiling a Slice Definition for Python
1
slice2py hello.ice
3、Writing a Server in Python:server.py


import sys, traceback, Ice
import Demo
class PrinterI(Demo.Printer):
    def printString(self, s, current=None):
        print s
status = 0
ic = None
try:
    ic = Ice.initialize(sys.argv)
    adapter = ic.createObjectAdapterWithEndpoints("SimplePrinterAdapter", "default -p 10000")
    object = PrinterI()
    adapter.add(object, ic.stringToIdentity("SimplePrinter"))
    adapter.activate()
    ic.waitForShutdown()
except:
    traceback.print_exc()
    status = 1
if ic:
    # Clean up
    try:
        ic.destroy()
    except:
        traceback.print_exc()
        status = 1
sys.exit(status)
4、Writing a Client in Python:client.py


import sys, traceback, Ice
import Demo
status = 0
ic = None
try:
    ic = Ice.initialize(sys.argv)
    base = ic.stringToProxy("SimplePrinter:default -p 10000")
    printer = Demo.PrinterPrx.checkedCast(base)
    if not printer:
        raise RuntimeError("Invalid proxy")
    printer.printString("python client say hello!")
except:
    traceback.print_exc()
    status = 1
if ic:
    # Clean up
    try:
        ic.destroy()
    except:
        traceback.print_exc()
        status = 1
sys.exit(status)
5、运行server端
1
python server.py
6、运行client端
1
python client.py
7、服务端运行结果如下图：服务端接收到了客户端消息


————————————————————————————
用上边的hello.ice、server.py
用php写客户端程序，通过ice进行通信
————————————————————————————

1、Compiling a Slice Definition for PHP
1
slice2php hello.ice
2、Writing a Client in PHP:client.php


require 'Ice.php';
require 'hello.php';
$ic = null;
try
{
    $ic = Ice_initialize();
    $base = $ic->stringToProxy("SimplePrinter:default -p 10000");
    $printer = Demo_PrinterPrxHelper::checkedCast($base);
    if(!$printer)
        throw new RuntimeException("Invalid proxy");
    $printer->printString("php client say hello!");
}
catch(Exception $ex)
{
    echo $ex;
}
if($ic)
{
    // Clean up
    try
    {
        $ic->destroy();
    }
    catch(Exception $ex)
    {
        echo $ex;
    }
}
?>
3、执行php或访问php
1
php -f client.php
4、服务端运行结果如下图：服务端接收到了客户端消息
