      ```
    
- Use docker-compose up to start the startup project with one click
    - ```shell script
      # Use docker-compose to start four containers
      docker-compose up
      # If you modify some configuration options, you can use this command to repackage the image
      docker-compose up --build
      # Use docker-compose to start in the background
      docker-compose up -d
      ```

    - Web project preview [http://127.0.0.1:8000](http://127.0.0.1:8000)

    - swagger APIs [http://127.0.0.1:8888/swagger/index.html](http://127.0.0.1:8888/swagger/index.html)

- If the internal ip of the server's 177.7.0.12 container is occupied, the place to be modified is

  - Replace 177.7.0.12 on line 39 of [docker-compose.yaml](./docker-compose.yaml) with the ip you want
  - Replace 177.7.0.12 in line 20 of [.docker-compose/nginx/conf.d/my.conf](./.docker-compose/nginx/conf.d/my.conf) with the ip you want

- docker-compose uses a custom docker network

    - ```dockerfile
        networks:
          network:
            ipam:
              driver: default
              config:
                - subnet: '177.7.0.0/16' 
        ```

    - Subnet address, the default gateway is 177.7.0.1 (docker-compose V2 needs to write, V3 does not need),For specific information, see the [official document](https://docs.docker.com/compose/compose-file/#ipv4_address-ipv6_address)

    - The default network name is gin-vue-admin_network, and the default is bridge mode

    - If the subnet is modified, the ipv4_address of each service needs to be modified, and the ip of the server on line 20 of [.docker-compose/nginx/conf.d/my.conf](.docker-compose/nginx/conf.d/my.conf) also needs to be modified

> <font color=red>**Use docker-compose to deploy this project need attention**</font>

- For mysql database, please use a local database installed on the server disk.
	- Avoid using mysql in the docker container, there may be write problems, io is lower than the host machine, docker's persistence mechanism problem
- [init.sql](.docker-compose/docker-entrypoint-initdb.d/init.sql) is for docker-compose ==experience this project==, prohibit the use of [init.sql](.docker-compose/docker-entrypoint-initdb.d/init.sql) to initialize project data, Database initialization[Please use this method](https://www.gin-vue-admin.com/docs/help#step1%EF%BC%9A%E6%95%B0%E6%8D%AE%E5%BA%93%E5%88%9D%E5%A7%8B%E5%8C%96)
	- Use [init.sql](.docker-compose/docker-entrypoint-initdb.d/init.sql) to initialize all problems, please bear it yourself, and have nothing to do with this project
- When deploying using docker-compose of this project,Please modify the [nginx configuration](.docker-compose/nginx/conf.d/my.conf), mysql configuration, networks configuration, redis configuration corresponding to [docker-compose.yaml](./docker-compose.yaml), and make changes as needed.

### 2.3 API docs auto-generation using swagger

#### 2.3.1 install swagger 

##### (1) Using VPN or outside mainland China
````
go get -u github.com/swaggo/swag/cmd/swag
````

##### (2) In mainland China

In mainland China, access to go.org/x is prohibited，we recommend [goproxy.io](https://goproxy.io/zh/)

````bash
If you are using Go version 1.13 and above (recommended)
# Enable Go Modules function
go env -w GO111MODULE=on 
# Configure GOPROXY environment variables
go env -w GOPROXY=https://goproxy.io,direct
If you are using Go version 1.12 and below
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.io

# Use the following command to download swag
go get -u github.com/swaggo/swag/cmd/swag
````

#### 2.3.2 API docs generation

````
cd server
swag init
````
After executing the above command，`docs` will show in `server/`，then open your browser, jump into `http://localhost:8888/swagger/index.html` to see the swagger APIs.


## 3. Technical selection

- Frontend: using `Element-UI` based on vue，to code the page.
- Backend: using `Gin` to quickly build basic RESTful API. `Gin` is a web framework written in Go (Golang).
- DB: `MySql`(5.6.44)，using `gorm` to implement data manipulation, added support for SQLite databases.
- Cache: using `Redis` to implement the recording of the JWT token of the currently active user and implement the multi-login restriction.
- API: using Swagger to auto generate APIs docs。
- Config: using `fsnotify` and `viper` to implement `yaml` config file。
- Log: using `go-logging` record logs。

- Authority management: Authority management based on `jwt` and `casbin`. 
- File upload & download: File upload operation based on Qiniu Cloud (In order to make it easier for everyone to test, I have provided various important tokens of my Qiniu test number, and I urge you not to make things a mess).
- Pagination Encapsulation：The frontend uses mixins to encapsulate paging, and the paging method can call mixins
- User management: The system administrator assigns user roles and role permissions.
- Role management: Create the main object of permission control, and then assign different API permissions and menu permissions to the role.
- Menu management: User dynamic menu configuration implementation, assigning different menus to different roles.
- API management: Different users can call different API permissions.

- Conditional search: Add an example of conditional search.
- Restful example: You can see sample APIs in user management module.

```
fontend code file: src\view\superAdmin\api\api.vue 
backend code file: model\dnModel\api.go 
```
- Multi-login restriction: Change `userMultipoint` to true in `system` in `config.yaml` (You need to configure redis and redis parameters yourself. During the test period, please report in time if there is a bug).
- Upload file by chunk：Provides examples of file upload and large file upload by chunk.
- Form Builder：With the help of [@form-generator](https://github.com/JakHuang/form-generator).
