原文地址:HTTP JSON API through the gRPC gateway
etcd v3 使用 gRPC 作为消息协议。etcd项目包括一个基于gRPC的Go客户端和一个命令行工具,etcdctl,通过gRPC与etcd集群进行交互.对于没有gRPC支持的语言,etcd提供JSON gRPC网关,这个网关提供一个RESTful风格的代理可以将HTTP/JSON请求转换为gRPC消息。
这个网关接受一个到etcd‘s buffer协议消息定义的JSON格式的映射,注意Key
和Value
字段定义为byte 数组,因此JSON必须使用base64编码,下面的例子使用curl
,但是每个HTTP/JSON客户端的工作原理都和例子相同。
注意
gRPC网关节点从etcd v3.3发生变化:
[CLIENT-URL]/v3alpha/*
。[CLIENT-URL]/v3beta/*
保持[CLIENT-URL]/v3alpha/*
使用。[CLIENT-URL]/v3/*
保持[CLIENT-URL]/v3beta/*
使用。
[CLIENT-URL]/v3alpha/*
被抛弃使用。[CLIENT-URL]/v3/*
。
[CLIENT-URL]/v3beta/*
被抛弃使用。使用/v3/kv/range
和/v3/kv/put
服务读和写Keys:
<<COMMENThttps://www.base64encode.org/foo is 'Zm9v' in Base64bar is 'YmFy'COMMENT
curl -L http://localhost:2379/v3/kv/put -X POST -d '{"key": "Zm9v", "value": "YmFy"}'# {"header":{"cluster_id":"12585971608760269493","member_id":"13847567121247652255","revision":"2","raft_term":"3"}}

使用/v3/watch
服务查看Keys:
curl -N http://localhost:2379/v3/watch -X POST -d '{"create_request": {"key":"Zm9v"} }' &# {"result":{"header":{"cluster_id":"12585971608760269493","member_id":"13847567121247652255","revision":"1","raft_term":"2"},"created":true}}
curl -L http://localhost:2379/v3/kv/put -X POST -d '{"key": "Zm9v", "value": "YmFy"}' >/dev/null 2>&1# {"result":{"header":{"cluster_id":"12585971608760269493","member_id":"13847567121247652255","revision":"2","raft_term":"2"},"events":[{"kv":{"key":"Zm9v","create_revision":"2","mod_revision":"2","version":"1","value":"YmFy"}}]}}
使用`/v3/kv/txn
发行一个交易:
# 目标创建
curl -L http://localhost:2379/v3/kv/txn -X POST -d '{"compare":[{"target":"CREATE","key":"Zm9v","createRevision":"2"}],"success":[{"requestPut":{"key":"Zm9v","value":"YmFy"}}]}'# {"header":{"cluster_id":"12585971608760269493","member_id":"13847567121247652255","revision":"3","raft_term":"2"},"succeeded":true,"responses":[{"response_put":{"header":{"revision":"3"}}}]}
# 目标版本
curl -L http://localhost:2379/v3/kv/txn -X POST -d '{"compare":[{"version":"4","result":"EQUAL","target":"VERSION","key":"Zm9v"}],"success":[{"requestRange":{"key":"Zm9v"}}]}'# {"header":{"cluster_id":"14841639068965178418","member_id":"10276657743932975437","revision":"6","raft_term":"3"},"succeeded":true,"responses":[{"response_range":{"header":{"revision":"6"},"kvs":[{"key":"Zm9v","create_revision":"2","mod_revision":"6","version":"4","value":"YmF6"}],"count":"1"}}]}
使用/v3/auth
设置权限:
# 创建root用户
curl -L http://localhost:2379/v3/auth/user/add -X POST -d '{"name": "root", "password": "pass"}'# {"header":{"cluster_id":"14841639068965178418","member_id":"10276657743932975437","revision":"1","raft_term":"2"}}
# 创建root角色
curl -L http://localhost:2379/v3/auth/role/add -X POST -d '{"name": "root"}'# {"header":{"cluster_id":"14841639068965178418","member_id":"10276657743932975437","revision":"1","raft_term":"2"}}
# 授予root角色
curl -L http://localhost:2379/v3/auth/user/grant -X POST -d '{"user": "root", "role": "root"}'# {"header":{"cluster_id":"14841639068965178418","member_id":"10276657743932975437","revision":"1","raft_term":"2"}}
# 开启认证
curl -L http://localhost:2379/v3/auth/enable -X POST -d '{}'# {"header":{"cluster_id":"14841639068965178418","member_id":"10276657743932975437","revision":"1","raft_term":"2"}}
通过/v3/auth/authenticate
服务使用一个认证令牌进行认证:
# 为根用户获取认证令牌
curl -L http://localhost:2379/v3/auth/authenticate -X POST -d '{"name": "root", "password": "pass"}'# {"header":{"cluster_id":"14841639068965178418","member_id":"10276657743932975437","revision":"1","raft_term":"2"},"token":"sssvIpwfnLAcWAQH.9"}
使用认证证书设置认证头部到认证令牌获取Keys:
curl -L http://localhost:2379/v3/kv/put -H 'Authorization : sssvIpwfnLAcWAQH.9' -X POST -d '{"key": "Zm9v", "value": "YmFy"}'# {"header":{"cluster_id":"14841639068965178418","member_id":"10276657743932975437","revision":"2","raft_term":"2"}}
