如果你想处理JAVA过来的接口。在PHP里面是这样表现的：

<?php
	$url = ‘此处为JAVA提供的接口URL地址‘; //我们统一用的是JSON格式
	$ch = curl_init();
	$timeout = 5;
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_POST, 1);
	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
	$contents = curl_exec($ch);
	curl_close($ch);
	$body = json_decode ($contents, TRUE);
	$data = array();
	if ( $body[‘code‘] == 200 )
	{
		$data = (array)$body[‘data‘];
	}
?>

下面是处理好了返回给javascript的JSON字符串。你只需要把控制器的地址用URL的形式给对接人员就可以了。

<?php
public function action_ActionName()
{
	header(‘Content-Type: application/x-javascript‘);
	// 例如只接收.baidu.com域名的请求
	header(‘Access-Control-Allow-Origin:.baidu.com‘);
	$callback = isset( $_GET[ ‘callback‘ ] ) ? $_GET[ ‘callback‘ ] : ‘callback‘;
	try {
		$rows = select * from *******; //此处为SELECT语句，从数据库取出结果
		$data = array(
			‘code‘ => 200,
			‘msg‘  => ‘成功‘,
			‘data‘ => $rows,
		);
	} catch (Exception $e) {
		$data = array(
			‘code‘ 	=> 3000004,
			‘msg‘	=> ‘非法的操作‘,
		);
	}
	echo $callback.‘(‘.json_encode($data).‘)‘;
	exit;
}

?>
