示例
服务器
回调绑定
<?php use JsonRPC\Server; $server = new Server(); $server->getProcedureHandler() ->withCallback('addition', function ($a, $b) { return $a + $b; }) ->withCallback('random', function ($start, $end) { return mt_rand($start, $end); }) ; echo $server->execute();
从数组中绑定回调
<?php use JsonRPC\Server; $callbacks = array( 'getA' => function() { return 'A'; }, 'getB' => function() { return 'B'; }, 'getC' => function() { return 'C'; } ); $server = new Server(); $server->getProcedureHandler()->withCallbackArray($callbacks); echo $server->execute();
类/方法绑定
<?php use JsonRPC\Server; class Api { public function doSomething($arg1, $arg2 = 3) { return $arg1 + $arg2; } } $server = new Server(); $procedureHandler = $server->getProcedureHandler(); // Bind the method Api::doSomething() to the procedure myProcedure $procedureHandler->withClassAndMethod('myProcedure', 'Api', 'doSomething'); // Use a class instance instead of the class name $procedureHandler->withClassAndMethod('mySecondProcedure', new Api, 'doSomething'); // The procedure and the method are the same $procedureHandler->withClassAndMethod('doSomething', 'Api'); // Attach the class, the client will be able to call directly Api::doSomething() $procedureHandler->withObject(new Api()); echo $server->execute();
从数组中绑定类/方法
<?php use JsonRPC\Server; class MathApi { public function addition($arg1, $arg2) { return $arg1 + $arg2; } public function subtraction($arg1, $arg2) { return $arg1 - $arg2; } public function multiplication($arg1, $arg2) { return $arg1 * $arg2; } public function division($arg1, $arg2) { return $arg1 / $arg2; } } $callbacks = array( 'addition' => array( 'MathApi', addition ), 'subtraction' => array( 'MathApi', subtraction ), 'multiplication' => array( 'MathApi', multiplication ), 'division' => array( 'MathApi', division ) ); $server = new Server(); $server->getProcedureHandler()->withClassAndMethodArray($callbacks); echo $server->execute();
服务器中间件
中间件可用于对客户端进行身份验证和授权。它们在每个过程之前执行。
<?php use JsonRPC\Server; use JsonRPC\MiddlewareInterface; use JsonRPC\Exception\AuthenticationFailureException; class Api { public function doSomething($arg1, $arg2 = 3) { return $arg1 + $arg2; } } class MyMiddleware implements MiddlewareInterface { public function execute($username, $password, $procedureName) { if ($username !== 'foobar') { throw new AuthenticationFailureException('Wrong credentials!'); } } } $server = new Server(); $server->getMiddlewareHandler()->withMiddleware(new MyMiddleware()); $server->getProcedureHandler()->withObject(new Api()); echo $server->execute();
当API凭证错误时,您可以抛出 AuthenticationFailureException
,当用户无权访问过程时,您可以抛出 AccessDeniedException
。
客户端
使用位置参数的示例
<?php use JsonRPC\Client; $client = new Client('https:///server.php'); $result = $client->execute('addition', [3, 5]);
使用命名参数的示例
<?php use JsonRPC\Client; $client = new Client('https:///server.php'); $result = $client->execute('random', ['end' => 10, 'start' => 1]);
参数按正确顺序调用。
使用魔术方法 __call()
的示例
<?php use JsonRPC\Client; $client = new Client('https:///server.php'); $result = $client->random(50, 100);
上面的示例使用位置参数进行请求,而此示例使用命名参数
$result = $client->random(['end' => 10, 'start' => 1]);
客户端批量请求
在单个HTTP请求中调用多个过程
<?php use JsonRPC\Client; $client = new Client('https:///server.php'); $results = $client->batch() ->foo(['arg1' => 'bar']) ->random(1, 100) ->add(4, 3) ->execute('add', [2, 5]) ->send(); print_r($results);
所有结果都存储在调用的相同位置。
客户端异常
客户端异常通常在服务器返回错误时抛出。您可以通过使用 $returnException
参数来更改此行为,这将导致返回异常。这在执行批量请求时非常有用。
BadFunctionCallException
:服务器上找不到过程InvalidArgumentException
:过程参数错误JsonRPC\Exception\AccessDeniedException
:访问被拒绝JsonRPC\Exception\ConnectionFailureException
:连接失败JsonRPC\Exception\ServerErrorException
:内部服务器错误
启用客户端调试
您可以通过启用调试模式来查看JSON请求和响应
<?php use JsonRPC\Client; $client = new Client('https:///server.php'); $client->getHttpClient()->withDebug();
调试输出将发送到PHP系统日志。您可以在您的 php.ini
中配置日志目标。
输出示例
==> Request: { "jsonrpc": "2.0", "method": "removeCategory", "id": 486782327, "params": [ 1 ] } ==> Response: { "jsonrpc": "2.0", "id": 486782327, "result": true }
基于IP的客户端限制
服务器可以仅允许一些IP地址
<?php use JsonRPC\Server; $server = new Server; // IP client restrictions $server->allowHosts(['192.168.0.1', '127.0.0.1']); [...] // Return the response to the client echo $server->execute();
如果客户端被阻止,您将收到一个403禁止的HTTP响应。
HTTP基本身份验证
如果您使用HTTPS,可以使用用户名/密码允许客户端。
<?php use JsonRPC\Server; $server = new Server; // List of users to allow $server->authentication(['user1' => 'password1', 'user2' => 'password2']); [...] // Return the response to the client echo $server->execute();
在客户端设置凭证如下
<?php use JsonRPC\Client; $client = new Client('https:///server.php'); $client->getHttpClient() ->withUsername('Foo') ->withPassword('Bar');
如果身份验证失败,客户端将抛出RuntimeException。
使用替代身份验证头
use JsonRPC\Server; $server = new Server(); $server->setAuthenticationHeader('X-Authentication'); $server->authentication(['myusername' => 'mypassword']);
上面的示例将使用HTTP头 X-Authentication
而不是标准的 Authorization: Basic [BASE64_CREDENTIALS]
。用户名/密码值需要以base64编码: base64_encode('username:password')
。
本地异常
默认情况下,服务器将所有异常中继到客户端。如果您只想中继其中一些,请使用方法 Server::withLocalException($exception)
<?php use JsonRPC\Server; class MyException1 extends Exception {}; class MyException2 extends Exception {}; $server = new Server(); // Exceptions that should NOT be relayed to the client, if they occurs $server ->withLocalException('MyException1') ->withLocalException('MyException2') ; [...] echo $server->execute();
在客户端请求之前调用回调
您可以使用回调在请求服务器之前更改HTTP头或URL。
示例
<?php $client = new Client(); $client->getHttpClient()->withBeforeRequestCallback(function(HttpClient $client, $payload) { $client->withHeaders(array('Content-Length: '.strlen($payload))); }); $client->myProcedure(123);
