框架func main() {
router := new (mux.Router)
router.HandleFunc("/",test2).Methods("GET")
core.HttpListen(router)
}
func test2(w http.ResponseWriter,r *http.Request) {
// 非常简单的例子, 操作放在内部 , 可以使用 request 来获取自己的参数,再直接组织输出
core.HandlerMapWithOutputJson(w, func() map[string]interface{} {
m := map[string]interface{}{}
m["msg"] = "blow me a kiss"
return m
})
}
// 结果 : {"msg":"blow me a kiss"}
func test3(w http.ResponseWriter,r *http.Request) {
core.HandlerMapWithOutputJson(w, func() map[string]interface{} {
// 插入一条评论
item := &model.Comment{
Id :util.NewId(), // 评论 id
UserId :"123456", // 评论人 id
Name :"LinGuanHong", // 评论人名称
Content :"hello word", // 评论内容
}
affect,_ := core.Engine.Insert(item) // 执行插入,传入 struct 引用
m := map[string]interface{}{}
if affect > 0 {
m["ret"] = "insert success"
comments := make([]model.Comment, 0)
core.Engine.Find(&comments) // select 出来,获取所有评论输出
m["msg"] = comments
}else{
m["ret"] = "insert failed"
}
return m
})
}
输出的结果是:
{
"msg": [
{
"id": "1kubpgh9pprrucy11e456fyytw",
"UserId": "123456",
"name": "LinGuanHong",
"content": "hello word"
}
],
"ret": "insert success"
}
目录如下
---- config
---- core
---- model
---- threeLibs
---- util
---- server.go
1 在 config
放置配置文件
服务端配置 json 文件
-- server.json,日志配置文件
-- log.json 例如下面的,他们都会在运行程序后会自动解析和读取
2 threeLibs
目录放置了依赖的第三方库,例如 xorm,不需要你再去 go get
3 model
放置数据实体 struct
{
"Host": "127.0.0.1",
"Port": ":8884",
"FilePort":":8885",
"DbName":"lgh",
"DbUser":"root",
