PHP或Python调用C++实现的服务器

周末2天，一天写了个php_cerl模块，完成cerl的php client，一天写了个pycerl模块，完成cerl的python client。呵呵，C++的server可以用php或者python来调用了。

对于我们之前用CERL写的HashServer这个服务器（一个很简单的样例，代码参阅：Erlang vs. CERL - CERL简介），其PHP写的Client样例如下：

view plaincopy to clipboardprint?
<?php
    define(HashSever_put, 1);
    define(HashSever_get, 2);

    if (!extension_loaded(php_cerl)) {
        if (!dl(php_cerl. . PHP_SHLIB_SUFFIX))
            die("ERROR: Cannot load php_cerl library! ");
    }

    cerl_thread_init();

    $server = cerl_connect(localhost:8889, HashServer);
    if (!$server)
        die("ERROR: Connect HashSever failed! ");

    printf(
        "+----------------------------------------------------------- " .
        "| put <key> <value> - Put (key, value) " .
        "| get <key> - Get value of a key " .
        "| q - Quit " .
        "+----------------------------------------------------------- ");

    for (;;)
    {
        echo " > ";
        list($cmd, $key, $value) = fscanf(STDIN, %s%d%d);
        if ($cmd == get || $cmd == g)
        {
            $ret = $server->call(HashSever_get, $key);
            if ($ret[0] == code_ok)
                echo "result: $ret[1] ";
            else
                echo "error: $ret[0] ";
        }
        else if ($cmd == put || $cmd == p)
        {
            $ret = $server->call(HashSever_put, $key, $value);
            if ($ret[0] == code_ok)
                echo "ok! ";
            else
                echo "error: $ret[0] ";
        }
        else if ($cmd == q)
        {
            break;
        }
        else
        {
            echo "unknown command! ";
        }
    }

    cerl_thread_term();
?>
<?php
define(HashSever_put, 1);
define(HashSever_get, 2);

if (!extension_loaded(php_cerl)) {
if (!dl(php_cerl. . PHP_SHLIB_SUFFIX))
die("ERROR: Cannot load php_cerl library! ");
}

cerl_thread_init();

$server = cerl_connect(localhost:8889, HashServer);
if (!$server)
die("ERROR: Connect HashSever failed! ");

printf(
"+----------------------------------------------------------- " .
"| put <key> <value> - Put (key, value) " .
"| get <key> - Get value of a key " .
"| q - Quit " .
"+----------------------------------------------------------- ");

for (;;)
{
echo " > ";
list($cmd, $key, $value) = fscanf(STDIN, %s%d%d);
if ($cmd == get || $cmd == g)
{
   $ret = $server->call(HashSever_get, $key);
   if ($ret[0] == code_ok)
    echo "result: $ret[1] ";
   else
    echo "error: $ret[0] ";
}
else if ($cmd == put || $cmd == p)
{
   $ret = $server->call(HashSever_put, $key, $value);
   if ($ret[0] == code_ok)
    echo "ok! ";
   else
    echo "error: $ret[0] ";
}
else if ($cmd == q)
{
   break;
}
else
{
   echo "unknown command! ";
}
}

cerl_thread_term();
?>

而Python写的Client样例如下：

view plaincopy to clipboardprint?
HashSever_put = 1
HashSever_get = 2

import sys, pycerl

pycerl.thread_init()

server = pycerl.connect("localhost:8889", "HashServer")
if not server:
print "ERROR: Connect HashSever failed!"
