The demo you gave is wrong

[zhangwuliang]

Demo:

etcd::Client etcd("http://127.0.0.1:4001");
pplx::task<etcd::Response> response_task = etcd.get("/test/key1").get();
 // ... do something else
etcd::Response response = response_task.get();
std::cout << response.value().as_string();

Hi， as you give above, line two:

 1. etcd.get("keyname")  should return type pplx::task<etcd::Response>
 2. etcd.get("keyname").get()  should return type  etcd::Response 

So, the correct code of line two should be :

etcd::Response response_task = etcd.get("/test/key1").get();

Fixed. Thanks for your attention on this project!
