WeiGo

V0.3.0版本(有数据库的增删改查)

Go框架 - WeiGo【weigo】

|project #项目目录

|----app #应用目录

|----config #配置目录

|----route #路由目录

|----weigo #框架目录

|----go.mod #项目go.mod文件

|----main.go #项目入口启动文件

特点:

MVC模式,M-模型(数据层), V-视图(页面层), C-控制器(请求响应)

使用:

配置

全部配置在一个json文件,json格式;

App:是项目配置

Log:日志配置

DB:数据库配置

`{

"App": {

 "Debug": true

},

"Log": {

 "SqlInfo": "console"

},

"DB": {

 "Type": "mysql",
 
 "Hostname": "127.0.0.1",
 
 "Port": "3306",
 
 "Database": "weigo",
 
 "Charset": "utf8mb4",
 
 "Username": "root",
 
 "Password": "root",
 
 "Prefix": "wei_"

} }`

路由:

在route目录下route.go里面注册好路由:

weigo.Router("/", &controller.IndexController{})

weigo.Router("/user/", &controller.UserController{})

第一个参数: 访问路劲,

user是控制器名称,对应app/controller/UserController.go文件里面的UserController结构体;

该结构体会有很多方法,方法名称不需要定义路由,自动匹配: 比如127.0.0.1:9099/user/userinfo 会访问UserController的UserInfo方法 路由全小写匹配

第二个参数: 控制器类型的变量

控制器:

控制器需要继承框架控制器:

type UserController struct { weigo.Controller }

视图:

在控制器方法里面,也就是结构体方法里面:

c.Display("")

参数空,则使用app/view/控制器名称/方法名称.html文件,不为空就使用参数模板

赋值变量:

c.Assign("name","唯一")

c是当前控制器

模板文件html使用:

<p>{{.name}}</p>

模型:

user模型: 路径:app/model/user.go 代码规则建议: 一个模型对应一个数据表,属于一个模块;

一个模型只能有一个结构体,就是此模型的结构体,命名一致

模型里面定义的都是改结构体的方法,无其他函数

模型方法如果要获取数据库数据,采用db获取:

rows, errorStr := weigo.DataBase.Table("cto_controller").SetFields("name,id").GetAll()

###数据库操作,支持链式操作

rows, errorStr := weigo.DataBase.Table("cto_controller").SetFields("name,id").GetAll()

链式操作之前,先获取数据库连接: weigo.DataBase

链式操作:先指定操作的数据表,两种方式: weigo.DataBase.Table("wei_user")

weigo.DataBase.Name("user")

Table:手动写全表名称

Name:不加前缀,前缀使用配置里面配置的前缀

SetFields:设置要查询的字段

Where:查询条件;可以传字符串;也可以传map

Where("name="weigo" and status=1")

Where(["name"=>"[:string]weigo","status"=>1]); //[:string]代表字符串,会加引号

Where(["name[like]"=>"weigo","status"=>1]);//[like]代表模糊查询

Group("age,status"):分组,传字符串

Having:传字符串

Order("uid desc,name asc"):排序,传字符串

Limit(10):GetAll有效,GetOne无效

Page(2,10):分页查询,第一个参数页面,第二个参数每页大小

GetOne:获取一条数据

GetAll:获取多条数据

连式操作:Table或者Name指定表,GetOne或者GetAll获取数据,其他的不分顺序

weigo.DataBase.Table("cto_controller").SetFields("name,id").Where().Group().Order().GetAll()

数据库增删查改:
