Nginx upsync 1.8.x

支持zookeeper

1. 使用zookeeper的rest api。由于zookeeper 的rest api不支持recursive参数，故修改zookeer rest api源码，以支持recursive。
   https://github.com/zexuan/zookeeper/blob/trunk/src/contrib/rest/src/java/org/apache/zookeeper/server/jersey/resources/ZNodeResource.java
   https://github.com/zexuan/zookeeper/blob/trunk/src/contrib/rest/src/java/org/apache/zookeeper/server/jersey/jaxb/ZChildrenStat.java

2.也可以做一个http代理，php代码如下：
`
date_default_timezone_set('PRC');
$url = "http://127.0.0.1:9998/znodes/v1/upstreams/test";

function send($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt ($ch, CURLOPT_URL, $url);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

function getChildren($url) {
    $rs = send($url . "?view=children");
    $rs = json_decode($rs, true);
    $children = $rs['children'];
    $arr = array();
    foreach($children as $child) {
        $data = send($url . '/' . $child . '?view=data');
        $arr[] = json_decode($data, true);
    }
    return $arr;
}


function response($url) {
    $res = array();
    $children = getChildren($url);
    if(!empty($children)) {
        $res['children'] = $children;
    }
    header('Content-type: application/json; charset=utf-8');
    echo json_encode($res);
}

response($url);

`

测试配置文件 nginx.conf
upsync 127.0.0.1:9998/znodes/v1/upstreams/test upsync_timeout=6m upsync_interval=500ms upsync_type=zk strong_dependency=off;

非常、非常感谢，支持zookeeper 超赞！

看你的说明是修改了zookeeper 的源码，这样是不是有点tricky？能不能不修改zookeeper，从而模块更加通用？并不一定必须要支持recursive，这个可行么？

方便告知你的邮箱吗？非常感谢！
