请问pyapollo暂时不支持集群么？

机器已经添加了server.properties文件，但是读取到的位置依然是default,并非是新增的集群。
所以请问是pyapllo暂时不支持集群么？

代码：
def test_apollo():
client = pyapollo.ApolloClient(app_id='pubtrans-analysis', cluster='default', config_server_url='http://192.168.110.24:8080', timeout=60)
client.start()
zookeeper = client.get_value('zookeeper', 'default_value')
print zookeeper
client.stop()
配置能获取到，但是过一会儿就会报错，具体内容如下
ReadTimeout: HTTPConnectionPool(host='192.168.110.24', port=8080): Read timed out. (read timeout=60)

uwsgi+django项目中配置的apollo，不能获取最新apollo数据

问题：

在uwsgi+django项目中接入apollo后发现，使用get_value获取到的数据是项目启动时cache中的数据，不能之后更新的apollo数据。

调试：

1、在 uncached_http_get 和get_value中分别打印了cache中的值，
在apollo后台修改数据，这时，uncached_http_get 会打印出最近的cache数据，
再调用get_value，发现，cache中值是旧的数据。

2、直接使用python manage runserver 启动项目，重复1的操作，发现，可以获取到最新的cache数据。

结论：

uwsgi启动项目使 get_vaule中的self 和 uncached_http_get 中的self并非一个对象。

不知道这个算不算bug，还是我uwsgi启的方式不对。如果有人碰到和我一样的问题并解决的朋友，请回复我一下，谢谢！

看了下代码，完全没有任何错误捕获，use_eventlet 也没有什么实际作用

use_eventlet 也没有什么实际作用

超时时间35秒太少了，要请求超时报错

apollo官方写的注1：由于服务端会hold住请求30秒，所以请确保客户端访问服务端的超时时间要大于30秒，最好是60秒以上，因为Apollo后续可能会调整服务端hold住请求的时间为60秒。

目前写的35秒会超时，改成60秒以上则正常

项目还在维护吗，有支持配置热更新的计划吗？

我说的页面配置更新后，后台自动获取新的配置，自动加载新的配置的操作，而不是还要去手动重启服务、
谢谢！

eventlet 如何使用，求demo

eventlet 如何使用？

如何实现监听配置变化了？

想问一下有多个环境的怎么配置？

連線會超時

第一次發起連線正常
但後面.stop 沒正常停止

仔細看除錯應是時序沒對準在.stop運行前又多跑了一次request

thread 模式下用户编写的代码无法收到 signal.SIGINT 信号

我在用 pyapollo 的 thread 模式编写 demo 时，signal.SIGINT 信号被 self._signal_handler 收到，导致 demo 程序无法退出。可否让 ApolloClient 不响应 signal.SIGINT，signal.SIGTERM 和 signal.SIGABRT 信号，改由用户在退出函数中显示调用 stop() 函数。

线程安全

请问这个是生产环境使用的代码吗？使用线程模式的话，连锁都不需要加吗？比如后台轮询线程会遍历 self._notification_map，前台线程在调用 get_value 的时候也有可能会修改 self._notification_map，这种情况下，应该会 crash 吧？之前并没有做个 python 多线程，求教

这个还有继续在维护吗？有不少BUG好像都没人处理

py客户端请问怎么使用namespace

没有看到设置namespace的地方

client不支持环境environment参数吗

Apollo的配置可以分environment (环境)

client = ApolloClient(appId=, cluster=, config_server_url=)
client.start()

这个client不支持这个参数吗

请问当apollo需要登录时，参数应该怎么写呢？谢谢！

这个对Apollo配置中心强依赖吗？

在客户端配置没有缓存？如果配置中心挂了，程序就会出错！是不是这样？

大神，怎么先接收key，然后根据key值获取对应的value值呢？

大神，怎么先接收key，然后根据key值获取对应的value值呢？
现在看这种情况是写固定了，需要在代码里传值，传哪个key就获取哪个key对应的值，是不支持还是我没有看懂代码，望指点一二，谢谢了
