## tutorial/3.Call_code_in_an_external_package
https://golang.google.cn/doc/tutorial/getting-started
When you need your code to do something that might have been implemented by someone else, you can look for a package that has functions you can use in your code.

1.  Make your printed message a little more interesting with a function from an external module.
    
    1.  Visit pkg.go.dev and [search for a "quote" package](https://pkg.go.dev/search?q=quote).
    2.  Locate and click the `rsc.io/quote` package in search results (if you see `rsc.io/quote/v3`, ignore it for now).
    3.  In the **Documentation** section, under **Index**, note the list of functions you can call from your code. You'll use the `Go` function.
    4.  At the top of this page, note that package `quote` is included in the `rsc.io/quote` module.
    
    You can use the pkg.go.dev site to find published modules whose packages have functions you can use in your own code. Packages are published in modules -- like `rsc.io/quote` -- where others can use them. Modules are improved with new versions over time, and you can upgrade your code to use the improved versions.
    
2.  In your Go code, import the `rsc.io/quote` package and add a call to its `Go` function.
    
    After adding the highlighted lines, your code should include the following:
    
    ```
    package main
    
    import "fmt"
    
    import "rsc.io/quote"
    
    func main() {
        fmt.Println(quote.Go())
    }
    
    ```
    
3.  Add new module requirements and sums.
    
    Go will add the `quote` module as a requirement, as well as a go.sum file for use in authenticating the module. For more, see [Authenticating modules](https://golang.google.cn/ref/mod#authenticating) in the Go Modules Reference.
    
    ```
    $ go mod tidy
    go: finding module for package rsc.io/quote
    go: found rsc.io/quote in rsc.io/quote v1.5.2
    
    ```
    
4.  Run your code to see the message generated by the function you're calling.
    
    ```
    $ go run .
    Don't communicate by sharing memory, share memory by communicating.
    
    ```
    
    Notice that your code calls the `Go` function, printing a clever message about communication.
    
    When you ran `go mod tidy`, it located and downloaded the `rsc.io/quote` module that contains the package you imported. By default, it downloaded the latest version -- v1.5.2.

启动数据库
sudo service mysql start
导入数据库数据
sudo mysql -uroot -p123456 < backup.sql
创建非root用户
sudo mysql -uroot -p123456
CREATE USER 'fzy'@'localhost' IDENTIFIED BY '123456';
GRANT ALL privileges ON case_library.* TO 'fzy'@'localhost'
myqsl -uroot -p123456
初始化数据库

show databases;
use case_library;
show tables;
select * from student_table;


router->APi->model->

npm install @logicflow/extension
npm install @logicflow/core
npm install vue-color

mysql
数据库名称 case_library
用户名 root
密码 123456

导出数据库
mysqldump -uroot -p123456 case_library > case_library.sql
mysql -ugva -p123456 gva< case_library.sql
docker-compose -f deploy/docker-compose/docker-compose.yaml up --build

# 容器构建
## 1. 构建镜像
docker-compose -f deploy/docker-compose/docker-compose.yaml up --build
## 2. 恢复数据库
ssh mysql 
cp case_LIBRARY.SQL
mysql -ugva -p123456 gva< case_library.sql

再设置一下权限 ok
