#   Riak HTTP interface stays true to their intent: 1xx Informational, 2xx Success,
#   3xx Further Action, 4xx Client Error, 5xx Server Error


### put

    ## it will generate a key you

        ;;
    ## for any kind of write, you can add the returnbody=true parameter to force a value return,
    ## 和值相关的头, 如X-Riak-Vclock, ETa这些都会被返回.
    ## post 也支持returnbody, get 会自动返回body,body才是内容,okey
    4   )   curl -i -X POST $url/people \

    ## Delete:
    ##  1 . 删除一个已经被删除的对象在Riak中会被表示为deleted,可以打一个 tombstone 标签。然后,
    ##  一个死神进程会被调用,这个进程会以后台的方式清理掉这些marked objs(可能的话,死神进程因该
    ##  关掉),
    ##  2. 有两点需注意:
    ##      A) 在Riak中,删除的操作与属于一个写的操作,在计算读写比率时候,也因该这样考虑
    ##      B) 检查一个存在的key并不能说明他对应的对象是否存在,因为你可能读到的key可能是在&#39;删除和
    ##  备份的期间&#39;,所以你必须要读到 tombstones为止,才能说明一个key已被删除了
    5   )   curl -i -X POST $url/people/test    \
                -H  &#39;Content-Type: application/json&#39;    \

            echo "-----------"
            curl -i -X DELETE $url/people/test
        ;;
    ## Lists -> Riak有两种不同lists,第一种列出集群中的所有buckets,第二种会根据指定的buckets列出所有的key,调用的方式相似,都是传入两个参数
    6   )	curl -i $url?buckets=true
			echo ""
			echo "==================="
			curl -i $url/food?keys=true
			echo ""
			echo "-------------------"
