向数据库添加数据
首先,获取一个uuid
curl -X GET http://127.0.0.1:5984/_uuids
{"uuids":["1925a2a284289df9b55b390525001ca1"]}
注意:每次得到的uuid不一样。
获取10个uuid: curl -X GET http://127.0.0.1:5984/_uuids?count=10使用uuid作为键插入一条数据
curl -X PUT http://127.0.0.1:5984/db1/1925a2a284289df9b55b390525001ca1 -d '{"title":"test","content":"this is test!"}'
{"ok":true,"id":"1925a2a284289df9b55b390525001ca1","rev":"1-4d3e6350fdcc39f7b482c4cab8ff5d9a"} -
更新记录
curl -X PUT http://127.0.0.1:5984/db1/1925a2a284289df9b55b390525001ca1 -d '{"title":"test","content":"this is test!modifyied!"}'
{"error":"conflict","reason":"Document update conflict."}
失败了。因为,couchdb是按版本提交的,同一个源提交多次会造成一定的混乱。所以,其采用了版本进行控制。curl -X PUT http://127.0.0.1:5984/db1/1925a2a284289df9b55b390525001ca1 -d '{"_rev":"1-4d3e6350fdcc39f7b482c4cab8ff5d9a","title":"test","content":"this is test!"}'
{"ok":true,"id":"1925a2a284289df9b55b390525001ca1","rev":"2-f6f24194b29981316f2412e288cda320"}
这样就没有问题了。 -
