文件存储微服务-- 基于 beego 开发

文件存储微服务#

上传文件是通用需求，所以我们最好把这个功能抽离出来，做成通用的，避免每次都重复写。

项目地址

安装#

    go get -u -v github.com/gamelife1314/filestoreCopy

修改配置#

   修改配置文件 conf/app.confCopy

启动服务#

  go run main.goCopy

启动服务之后，会自动创建相关的数据表，无须手动创建的。

示例#

1. 创建一个 Client ，可以把这个 Client 想象成一个站点。

   $  http POST http://127.0.0.1:8080/v1/client
       HTTP/1.1 200 OK
       Access-Control-Allow-Credentials: true
       Access-Control-Allow-Headers: Origin, Content-Type, Accept
       Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, PATCH, DELETE
       Access-Control-Allow-Origin: 127.0.0.1
       Content-Length: 157
       Content-Type: application/json; charset=utf-8
       Date: Sun, 29 Jul 2018 03:27:40 GMT
       Server: beegoServer:1.10.0
   
       {
           "code": 2000,
           "data": {
               "client_id": "6949186648068646",
               "client_secret": "&gT#MY,q~NFO"
           },
           "message": "create client successfully!"
       }Copy

2. 申请 token 用于随后的文件上传以及下载

   $ http --form  http://127.0.0.1:8080/v1/token client_id="6949186648068646" client_secret="&gT#MY,q~NFO" expires=5000000
       HTTP/1.1 200 OK
       Access-Control-Allow-Credentials: true
       Access-Control-Allow-Headers: Origin, Content-Type, Accept
       Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, PATCH, DELETE
       Access-Control-Allow-Origin: 127.0.0.1
       Content-Length: 231
       Content-Type: application/json; charset=utf-8
       Date: Sun, 29 Jul 2018 03:29:33 GMT
       Server: beegoServer:1.10.0
   
       {
           "code": 2012,
           "data": {
               "client_id": "6949186648068646",
               "created_at": "2018-07-29 11:29:33",
               "expires": 1537834973,
               "token": "e45823d7246578a07fc7675672e25342"
           },
           "message": "token create successfully!"
       }Copy

3. 上传文件，会上传到配置项 uploadFilesDir 目录中。

   $ http --form http://127.0.0.1:8080/v1/file/upload token=e45823d7246578a07fc7675672e25342 path=/ file@~/Desktop/2.jpg
       HTTP/1.1 200 OK
       Access-Control-Allow-Credentials: true
       Access-Control-Allow-Headers: Origin, Content-Type, Accept
       Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, PATCH, DELETE
       Access-Control-Allow-Origin: 127.0.0.1
       Content-Length: 118
       Content-Type: application/json; charset=utf-8
       Date: Sun, 29 Jul 2018 03:31:11 GMT
       Server: beegoServer:1.10.0
   
       {
           "code": 2030,
           "data": {
               "slug": "cab424f5733d8d63173c6d4218e23a18"
           },
           "message": "uplod file success!"
       }Copy

4. 每个文件都有一个标识，通过这个标识下载相应的文件。

   $ http --download  http://127.0.0.1:8080/v1/file/download token==e45823d7246578a07fc7675672e25342 slug==cab424f5733d8d63173c6d4218e23a18
       HTTP/1.1 200 OK
       Accept-Ranges: bytes
       Access-Control-Allow-Credentials: true
       Access-Control-Allow-Headers: Origin, Content-Type, Accept
       Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, PATCH, DELETE
       Access-Control-Allow-Origin: 127.0.0.1
       Cache-Control: public
       Content-Description: File Transfer
       Content-Disposition: attachment; filename=2.jpg
       Content-Length: 3642
       Content-Transfer-Encoding: binary
       Content-Type: image/jpeg
       Date: Sun, 29 Jul 2018 03:33:20 GMT
       Expires: 0
       Last-Modified: Sun, 29 Jul 2018 03:31:11 GMT
       Pragma: public
       Server: beegoServer:1.10.0
