# dubbo-php-client
the dubbo php client(中文说明往下拉)

[Dubbo](https://github.com/alibaba/dubbo) is a distributed service framework empowers applications with service import/export capability with high performance RPC.

This is only dubbo php clinet implementation. It's only support jsonRPC now.
you can see the example for the [dubbo-jsonRPC-demo](https://github.com/quickj/dubbo_jsonrpc_demo) which i write before.
##### Notice:
you must start dubbo and zookeeper,register prividers first.
### Installation
If you have not installed [zookeeper extension](http://pecl.php.net/package/zookeeper) for php,then
```bash
sudo apt-get install php-pear php5-dev make
sudo pecl install zookeeper
```
Maybe occuring an error with "zookeeper support requires libzookeeper" when you install the zookeeper extension,you should install the libzookeeper needed.
```bash
cd ${your zookeeper home dir}/src/c/
./configure
make
sudo make install
```
Add zookeeper.so to your php.ini(/etc/php5/apache2/php.ini and /etc/php5/cli/php.ini)
```bash
extension="/usr/lib/php5/20121212/zookeeper.so"
```

##### Require dubbo-php-client package to your project(composer)
```bash
composer require -vvv "quickj/dubbo-php-client:dev-master"
```

### Usage
```php

use DubboPhp\Client\Client;

$options = [
'registry_address' => '127.0.0.1:2181',
'version' => '1.0.0',
'group' =>null,
'protocol' => 'jsonrpc'
];

try {
$dubboCli = new Client($options);
$testService = $dubboCli->getService("com.dubbo.demo.HelloService");
$ret = $testService->hello("dubbo php client");
var_dump($ret);
$mapRet = $testService->mapEcho();
var_dump($mapRet);

$objectRet = $testService->objectEcho();
var_dump($objectRet);

/**
* getService method support 2 way. If the forceVgp = true, It will assign the function parameter to service version,group and protocol. Default way is assign the $options configs to these.
* getService支持两种方式调用。如果forceVgp=true, 该方法将使用传参来绑定服务的版本号,组和协议。默认方式是使用$options数组里的配置绑定。
*/
$testServiceWithvgp = $dubboCli->getService("com.dubbo.demo.HelloService","1.0.0",null, $forceVgp = true);
$vgpRet = $testServiceWithvgp->hello("this request from vgp");
var_dump($vgpRet);
} catch (\DubboPhp\Client\DubboPhpException $e) {
print($e->getMessage());
}

```

# dubbo-php-client 中文说明
[DUBBO](https://github.com/alibaba/dubbo)是一个分布式服务框架,致力于提供高性能和透明化的RPC远程服务调用方案,是阿里巴巴SOA服务化治理方案的核心框架
这是dubbo的唯一php客户端,目前只支持jsonRPC协议,将来会支持多种协议。你可以查看我之前写的[dubbo-jsonRPC-demo](https://github.com/quickj/dubbo_jsonrpc_demo)例子。
##### 注意:
使用之前你必须安装和启动dubbo,zookeeper,注册服务者。

### 安装
如果你还没安装php的[zookeeper扩展](http://pecl.php.net/package/zookeeper),需要
```bash
sudo apt-get install php-pear php5-dev make
sudo pecl install zookeeper
```

有可能安装过程中会报错"zookeeper support requires libzookeeper",说明缺少libzookeeper库,你首先需要安装该库。
```bash
cd ${your zookeeper home dir}/src/c/
./configure
make
sudo make install
```
添加 zookeeper.so 到你的php.ini(/etc/php5/apache2/php.ini和/etc/php5/cli/php.ini)
添加以下这行
```bash
extension="/usr/lib/php5/20121212/zookeeper.so"
```

# 按Composer规范使用dubbo-php-client

```bash
composer require -vvv "quickj/dubbo-php-client:dev-master"

```

### 调用样例-直接类调用:

```php

use DubboPhp\Client\Client;

$options = [
'registry_address' => '127.0.0.1:2181',
'version' => '1.0.0',
'group' =>null,
'protocol' => 'jsonrpc'
];

try {
$dubboCli = new Client($options);
$testService = $dubboCli->getService("com.dubbo.demo.HelloService");
$ret = $testService->hello("dubbo php client");
var_dump($ret);
$mapRet = $testService->mapEcho();
var_dump($mapRet);

$objectRet = $testService->objectEcho();
var_dump($objectRet);

/**
* getService method support 2 way. If the forceVgp = true, It will assign the function parameter to service version,group and protocol. Default way is assign the $options configs to these.
* getService支持两种方式调用。如果forceVgp=true, 该方法将使用传参来绑定服务的版本号,组和协议。默认方式是使用$options数组里的配置绑定。
*/
$testServiceWithvgp = $dubboCli->getService("com.dubbo.demo.HelloService","1.0.0",null, $forceVgp = true);
$vgpRet = $testServiceWithvgp->hello("this request from vgp");
var_dump($vgpRet);
} catch (\DubboPhp\Client\DubboPhpException $e) {
print($e->getMessage());
}

```

### Laravel组件模式安装

config/app.php的

providers数组中增加:

```php
DubboPhp\Client\DubboPhpClientServiceProvider::class
```

aliases别名数组中增加:

```php

'DubboPhpClient'=>DubboPhp\Client\Facades\DubboPhpClient::class,

'DubboPhpClientFactory'=>DubboPhp\Client\Facades\DubboPhpClientFactory::class,

```

然后命令行发布一下系统基本配置文件dubbo_cli.php到config路径:

```php
php artisan vendor:publish --provider="DubboPhp\Client\DubboPhpClientServiceProvider"

```

基本安装配置完成,相关的配置在config('dubbo_cli.default')中设置,具体参考配置文件

### Laravel中的使用:

#### 单实例方式(配置读取config('dubbo_cli.default')):

```php
$testService = DubboPhpClient::getService('com.dubbo.demo.HelloService');

$ret = $testService->hello("dubbo php client");
var_dump($ret);

```

#### 多实例的方式(配置读取config('dubbo_cli.connections.xxx')):

```php
$clientA = DubboPhpClientFactory::factory(config('dubbo_cli.connections.xxxA'));
$testServiceA = $clientA->getService('com.dubbo.demo.HelloService');
$retA = $testServiceA->hello("dubbo php client");
var_dump($retA);

$clientB = DubboPhpClientFactory::factory(config('dubbo_cli.connections.xxxB'));
$testServiceB = $clientB->getService('com.dubbo.demo.HelloService');
$retB = $testServiceB->hello("dubbo php client");
var_dump($retB);

```
