代码拉取完成,页面将自动刷新
轻量级,高性能 JsonRPC 2.0 客户端和服务端的php扩展,基于 multi_curl + epoll的并行客户端。Jsonrpc_Client使用libcurl库的并行接口调取服务,使用IO多路复用的epoll去监听curl的IO事件,使用协程可以同步返回rpc的数据,但底层其实是异步的。Jsonrpc_Server支持php-fpm或swoole。遵守http://www.jsonrpc.org/协议规范。 English

注册函数
<?php
$server = new Jsonrpc_Server();
// style one function variable
$add1 = function($a, $b){
return $a + $b;
};
$server->register('addition1', $add1);
// style two function string
function add2($a, $b){
return $a + $b;
}
$server->register('addition2', 'add2');
// style three function closure
$server->register('addition3', function ($a, $b) {
return $a + $b;
});
//style four class method string
class Api
{
static public function add($a, $b)

$server->register('addition4', 'Api::add');
echo $server->execute();
//output >>>

绑定方法
<?php

return $a + $b;

public function newadd($a,$b){

swoole jsonrpc server
<?php
$http = new swoole_http_server("127.0.0.1", 9501);
function add($a, $b){
return $a + $b;

$http->on('Request', function($request, $response){

持久化
Jsonrpc_client(1) 参数为1的时候,将epoll和curl_multi队列两个资源进行持久化,默认使用非持久化。
直接调用
<?php
$client = new Jsonrpc_Client(1);
$client->connect('http://localhost/server.php');
$client->addition1(3,5);
$result = $client->execute();
?>
并行调用
<?php
$client = new Jsonrpc_Client(1);
$client->call('http://localhost/server.php', 'addition1', array(3,5));
$client->call('http://localhost/server.php', 'addition2', array(10,20));
/* ... */
$result = $client->execute();
var_dump($result);
//output >>>
/*
array(2) {
[0]=>
array(3) {
["jsonrpc"]=>
string(3) "2.0"
["id"]=>

int(8)
}
[1]=>
array(3) {

string(3) "2.0"
["id"]=>
int(1559316299)
["result"]=>
int(30)
}
...
}
*/
?>
自定义 id
<?php
$client = new Jsonrpc_client(1);
$client->call('http://localhost/server.php', 'addition', array(3,5),"custom_id_001");
$result = $client->execute();
var_dump($result);
//output >>>
/*
array(1) {
[0]=>
array(3) {
["jsonrpc"]=>
string(3) "2.0"
["id"]=>

["result"]=>
int(8)

生成
<?php
$arr = array(
1,
"string",
array("key"=>"value")
);
var_dump(Jsonrpc_Yajl::generate($arr));
/* ==>output

解析
<?php
$str = '[1,"string",{"key":"value"}]';
var_dump(Jsonrpc_Yajl::parse($str));
