python如何为php写后端？

分类： · 2021-12-31

听到这样一种说法：PHP做前端，python做后端。
感觉是PHP写控制器，python写Model层。
在google上搜了半天也没有个答案。
有人说用python写接口，PHP调用。怎么个实现法呢？还望高手指点一下。

是否是PHP访问Python写的Service? – 黄新颖 2011-09-09

PHP做前端，PYTHON做后端，为啥要这么做呢，没感觉有什么优点。

以下是找来的一段示例，原作者为：http://www.quou.cn/archives/673，用socket连接。

PYTHON代码:

import time

import json

import socket

import traceback

import threading

importSocketServer

classToo:

def __init__(self):

print\'Welcome!\'

def test(self, args):

return\'xxx:%s\'% args;

def error(self, args):

return\'not function!\'

classThreadedTCPRequestHandler(SocketServer.BaseRequestHandler):

def handle(self):

whileTrue:

try:

data =self.request.recv(1024)

ifnot data:

print\'end\'
break

data = json.read(data)

res =  getattr(self._object, data[\'func\'],\'error\')(data[\'args\'])

ifnot res:

res =\'\'

res = str(len(res)).rjust(8,\'0\')+str(res)

self.request.send(res)

except:

print\'error in ThreadedTCPRequestHandler :%s, res:%s\'%(traceback.format_exc(), data)

classThreadedTCPServer(SocketServer.ThreadingMixIn,SocketServer.TCPServer):
pass

classServer:

def __init__(self, host, port):

self.host = host

self.port = port

ThreadedTCPServer.allow_reuse_address =True

def open(self,object):

ThreadedTCPRequestHandler._object =object

server =ThreadedTCPServer((self.host,self.port),ThreadedTCPRequestHandler)

server.serve_forever()

if __name__ ==\'__main__\':

Server(\'0.0.0.0\',10009).open(Too())

PHP代码：

<?php

class server{

private $_host;

private $_port;

private $_error;

private $_socket;

private $_class;

function __construct($host, $port){

$this->_host = $host;

$this->_port = $port;

$this->_class =\'\';

$this->_connect();
}

privatefunction _connect(){

$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

if($sock===false){

$this->_error(\'error socket_create\'.socket_strerror(socket_last_error()));
}

$ret = socket_connect($sock, $this->_host, $this->_port);

if($ret===false){

$this->_error(\'error socket_connect\'.socket_strerror(socket_last_error()));
}

$this->_socket = $sock;
}

publicfunctionobject($class){

$this->_class = $class;

return $this;
}

publicfunction __call($func, $args){

$data = array(\'class\'=> $this->_class,\'func\'=> $func,\'args\'=> $args);

$data = json_encode($data);

$socket = $this->_socket;

$res = socket_write($socket, $data, strlen($data));

if($res===false){

$this->_error(\'error socket_write\'.socket_strerror(socket_last_error()));
}

$res = socket_read($socket,1024, PHP_BINARY_READ);

$result = substr($res,8);

$len = intval(substr($res,0,8));

while(true){

if($len != strlen($result)){

$result .= socket_read($socket,1024, PHP_BINARY_READ);

}else{

break;
}
}

return $result;
}

privatefunction _error($errMsg =\'\'){

$this->_error = $errMsg;

echo $errMsg;

exit();
}

publicfunction __destruct(){

$socket = $this->_socket;

socket_write($socket,\'\',0);//结束

socket_close($socket);
}
}

function microtime_float(){

list($usec, $sec)= explode(" ", microtime());

return((float)$usec +(float)$sec);
}

$start = microtime_float();

$s =new server(\'127.0.0.1\',10009);

$res1 = $s->object(\'Too\')->test(\'a\',\'b\');

$res2 = $s->object(\'Too\')->test(\'a\',\'b\');

$end = microtime_float();

echo $res1.$res2.\'<br />\';

echo \'cost:\'.($end-$start);
?>

个人感觉没有必要这么复杂，你可以写个HTTP的API就能实现对应的功能，当然可以考虑使用远程调用的样子，但是没有你想的那么复杂，你去看下PHPRPC这个开源工程【别被名称迷惑了，也包含 Python，Ruby，Java等多个版本】，是一个简化的远程调用项目，比XML方便多了，我一直在用这个工程做“C/S“结构的站点：
官方地址： http://www.phprpc.org

服务器端可以使用任意语言，比如这里的Python

from phprpc import PHPRPC_Server # 引入 PHPRPC Server

import datetime

def helloworld():

    return\'helloworld\'

def hi(name):

    return\'hi %s\'% name

server = PHPRPC_Server()

server.add(helloworld)

server.add(\'hi\')

server.add(hi,\'hello\')

server.add(datetime.datetime.now)

server.debug =True

server.start()

客户端可以使用任意语言，比如Python和你说的PHP的

from flup.middleware.session importMemorySessionStore,SessionMiddleware

from flup.middleware.gzip importGzipMiddleware

from phprpc import PHPRPC_WSGIApplication,UrlMapMiddleware, PHPRPC_Server

import datetime

def helloworld():

    return\'helloworld\'

def hi(name):

    return\'hi %s\'% name

app = PHPRPC_WSGIApplication()

app.add(helloworld)

app.add(\'hi\')

app.add(hi,\'hello\')

app.add(datetime.datetime.now)

app.debug =True

app =UrlMapMiddleware([(\'/\', app)])

sessionStore =MemorySessionStore()

app =SessionMiddleware(sessionStore, app)

app =GzipMiddleware(app)

PHPRPC_Server(app = app).start()

下面的是PHP的内容：

<?php

include ("php/phprpc_client.php");

$client =new PHPRPC_Client();

$client->setProxy(NULL);

$client->useService(\'http://127.0.0.1/server.php\');

$client->setKeyLength(1000);

$client->setEncryptMode(3);

$client->setCharset(\'UTF-8\');

$client->setTimeout(10);

echo $client->hi(\'PHPRPC\'),"\r\n";

echo $client->getKeyLength(),"\r\n";

echo $client->getEncryptMode(),"\r\n";

echo $client->getCharset(),"\r\n";

echo $client->getTimeout(),"\r\n";
?>

试试这个工程吧，还支持默认的自动对称加密协商，保证在不安全的HTTP方式上安全的传输调用的内容
