PHP中的RPC / XML-RPC / JSON-RPC

Question

我在PHP XML-RPC / JSON-RPC客户机和服务器中查找XML-RPC和JSON-RPC的示例或教程

有人能告诉我吗？

谢谢?对不起，我的英语不太好。

对于JSON-RPC，您可以使用以下命令: jsonrpcphp

请参见示例:服务器

<?php
require_once 'example.php';
$myExample = new example();

// performs some basic operation
echo '<b>Attempt to perform basic operations</b><br />'."\n";
try {
    echo 'Your name is <i>'.$myExample->giveMeSomeData('name').'</i><br />'."\n";
    $myExample->changeYourState('I am using this function from the local environement');
    echo 'Your status request has been accepted<br />'."\n";
} catch (Exception $e) {
    echo nl2br($e->getMessage()).'<br />'."\n";
}

// performs some strategic operation, locally allowed
echo '<br /><b>Attempt to store strategic data</b><br />'."\n";
try {
    $myExample->writeSomething('Strategic string!');
    echo 'Strategic data succefully stored';
} catch (Exception $e) {
    echo nl2br($e->getMessage());
}
?>

客户端

<?php
require_once 'jsonRPCClient.php';
$myExample = new jsonRPCClient('http://jsonrpcphp.org/server.php');

// performs some basic operation
echo '<b>Attempt to perform basic operations</b><br />'."\n";
try {
    echo 'Your name is <i>'.$myExample->giveMeSomeData('name').'</i><br />'."\n";
    $myExample->changeYourState('I am using this function from the network');
    echo 'Your status request has been accepted<br />'."\n";
} catch (Exception $e) {
    echo nl2br($e->getMessage()).'<br />'."\n";
}

// performs some strategic operation, locally allowed
echo '<br /><b>Attempt to store strategic data</b><br />'."\n";
try {
    $myExample->writeSomething('Strategic string!');
    echo 'Strategic data succefully stored';
} catch (Exception $e) {
    echo nl2br($e->getMessage());
}
?>

我认为实现json-rpc服务的最好方法是使用Zend组件Zend_Json_Server。

因此，我建议您在php中使用Zend_Json组件来实现json-rpc服务。Zend框架允许“开箱即用”其组件。所以你可以像下面这样做一个结构：

Project
   |
   ------libs/Zend
                |
                -----Json/
                       |
                       -----Server/
                |
                -----Loader.php

并实现类似这样的东西：

<?php

  // path to dir with Zend root
  set_include_path(__DIR__ . "/libs");
  // path to Zend loader
  require_once __DIR__ . "/libs/Zend/Loader.php";

  Zend_Loader::loadClass('Zend_Json_Server');

  $server = new Zend_Json_Server();
  $server->setClass('Service');

  /**
   * Service Implementation
   */
  class Service
  {
      public function __construct()
      {
        // init some service attributes ...
      }

      /**
       * example of api method exposed by service
       * return "hello world" message
       * @param $domain
       * @return object (json)
       */
       public function helloworld()
       {
            $aOut = array('msg' => 'hello world');
            return json_encode($aOut);
       }

       // ... other methods of the service

 }

try {
    $output = $server->handle();
    echo $output;
} catch (Exception $e) {
    echo  ($e->getMessage());
    //header('HTTP/1.1 400 BAD REQUEST');
    exit();
}

关于客户端，您可以在post请求中发送如下json消息：

{ 
    "jsonrpc": "2.0", 
    "method": "helloworld", 
    "params": {}, 
    "id": 1 
}

在这篇文章Send json post using php中，你可以看到一些通过curl或Http Zend module的json请求的例子。
