获取数据并转为对应的类型
- ?id=111&id=122
c.GetInt("id")
int,111
- ?id=111&id=122
c.GetBool("id")
bool,false
- ?id=111&id=122
c.GetString("id")
string,"111"
- ?id=111&id=122
c.GetStrings("id")
[]string,[]string{"111", "122"}
- ?id=111&id=122
c.Input().Get("id")
string,"111"
解析表单
type user struct {
Id int `form:"-"`
Name interface{} `form:"name"`
Age int `form:"age"`
Email string
}
func (c *MainController) Post() {
u := user{}
c.ParseForm(&u)
fmt.Printf("%T,%#v
", u, u)
c.Ctx.WriteString("hello")
}
解析Request Body
type user struct {
Id int `json:"-"`
Name interface{} `json:"name"`
Age int `json:"age"`
Email string
}
func (c *MainController) Post() {
var u user
json.Unmarshal(c.Ctx.Input.RequestBody, &u)
fmt.Printf("%T,%#v
", u, u)
c.Ctx.WriteString("hello")
}
上传文件
<form enctype="multipart/form-data" method="post" action="http://localhost:8080/">
<input type="file" name="uploadname" />
<input type="submit">
</form>
func (c *MainController) Post() {
f, h, err := c.GetFile("uploadname")
if err != nil {
log.Fatal("getfile err ", err)
}
fmt.Printf("%T,%#v
", f, f)
defer f.Close()
c.SaveToFile("uploadname", "static/upload/" + h.Filename) // 保存位置在 static/upload, 没有文件夹要先创建
c.Ctx.WriteString("post")
}
后端返回数据到前端
c.Ctx.WriteString("<h1>hello world</h1>")
c.Data["name"] = "mm"
c.Data["age"] = 22
c.TplName = "user.html"
<body>
<h1>user</h1>
{{.name}}
{{.age}}
</body>
type user struct {
Name string `json:"name"`
Age int `json:"age"`
Birth time.Time `json:"birth"`
}
func (u *UserController) Get() {
var p1 = &user{
Name: "mm",
Age: 22,
Birth: time.Now(),
}
u.Data["json"] = p1
u.ServeJSON()
}
