go-mysql-api

go-mysql-api

provide restful api for mysql/mariadb database

Based on Echo, goqu, cli and go-mysql-driver

install

get go-mysql-api with go env

go get -u -v https://github.com/xuybin/go-mysql-api

or download binary from release page !

or see docker image instance

start server

You could run go-mysql-api binary from cli directly

go-mysql-api --help
Options:

  -h, --help                        display help information
  -c, --*conn[=$API_CONN_STR]      *mysql connection str
  -l, --*listen[=$API_HOST_LS]     *listen host and port
  -n, --noinfo[=$API_NO_USE_INFO]   dont use mysql information shcema

defaultly, server will retrive metadata from mysql information schema, if there are any problem, pls use -n option

start

you could start will cli args, but env var also works

go-mysql-api -c "user:pass@tcp(127.0.0.1:3306)/test" -l "0.0.0.0:80"

[INFO] 2017-07-26T15:09:48.4086821+08:00 connected to mysql with conn_str: user:pass@tcp(127.0.0.1:3306)/test
[INFO] 2017-07-26T15:09:49.7367783+08:00 retrived metadata from mysql database: test
[INFO] 2017-07-26T15:09:49.7367783+08:00 server start at :80

more information about connection str, please see here

docker

if you use docker, set environment vars to setup your server

docker run -d -p 8080:80 --link mysql_1:mysql -e API_CONN_STR='user:pass@tcp(mysql:3306)/test' --name mysql_api xuybin/go-mysql-api:version

please use correct connection string, or connectwith with public mysql database

apis

if you have any web dev experience, apis will easy to understand

s.GET("/api/metadata/", endpointMetadata(api)).Name = "Database Metadata"
s.POST("/api/echo/", endpointEcho).Name = "Echo API"
s.GET("/api/endpoints/", endpointServerEndpoints(s)).Name = "Server Endpoints"
s.HEAD("/api/metadata/", endpointUpdateMetadata(api)).Name = "Update DB Metadata"
s.GET("/api/swagger/", endpointSwaggerJSON(api)).Name = "Swagger Infomation"
s.GET("/api/docs/", endpointSwaggerUI).Name = "Swagger UI"

s.GET("/api/:table", endpointTableGet(api)).Name = "Retrive Some Records"
s.POST("/api/:table", endpointTableCreate(api)).Name = "Create Single Record"
s.DELETE("/api/:table", endpointTableDelete(api)).Name = "Remove Some Records"

s.GET("/api/:table/:id", endpointTableGetSpecific(api)).Name = "Retrive Record By ID"
s.DELETE("/api/:table/:id", endpointTableDeleteSpecific(api)).Name = "Delete Record By ID"
s.PATCH("/api/:table/:id", endpointTableUpdateSpecific(api)).Name = "Update Record By ID"

s.POST("/api/:table/batch/", endpointBatchCreate(api)).Name = "Batch Create Records"

Swagger UI Support

The go-mysql-api support swagger.json and provide swagger.html page

Open /api/docs/ to see swagger documents, the interactive documention will be helpful.

And go-mysql-api provide the swagger.json at path /api/swagger/

Get DB Metadata

You could use GET /api/metadata get database metadata

Operate record

• use POST /api/user method to create new user record

body

{
    "uname":"fjdasl@fjdksalf",
    "utoken":"atoken"
}

• use GET /api/user/31 to get our created record

{
    "status": 200,
    "message": "get table by id",
    "data": [
        {
            "create_at": "2017-07-18 03:21:16",
            "uid": "31",
            "uname": "fjdasl@fjdksalf",
            "utoken": "atoken"
        }
    ]
}

• use DELETE /api/user/31 to delete the record, (body is not needed)

Advance query

query apis could use index, size, fields, where, link and search in query param

Whole table search, with low query performance

GET /api/user?search=outlook

-- SQL mapping
SELECT * FROM `user`
  WHERE
    (
      (`create_at` LIKE BINARY '%outlook%')
        OR
      (`uid` LIKE BINARY '%outlook%')
        OR
      (`uname` LIKE BINARY '%outlook%')
        OR
      (`utoken` LIKE BINARY '%outlook%')
    )

Auto join and custome query

You could use in, notIn, like, is, neq, isNot and eq in where param

GET /api/monitor?link=user&link=monitor_log&size=100&where='user.uid'.in(11,22)&where='monitor_log.success'.eq(false)

-- SQL mapping
SELECT * FROM `monitor`
  INNER JOIN `user`
    ON (`user`.`uid` = `monitor`.`uid`)
  INNER JOIN `monitor_log`
    ON (`monitor_log`.`mid` = `monitor`.`mid`)
  WHERE
    (
      (`user`.`uid` IN ('11', '22'))
    AND
      (`monitor_log`.`success` = 'false')
    )
  size 100

Even if go-mysql-api has already supported simple association query, we still recommend using views for complex queries

Some tests

yeah, there are some in-package tests, but not work for out-package, and based on env var

I test this project by my existed mysql schema, and it works correctly
