在使用beego时遇到 need a primary key field
1 确保结构中的 字段首字母大写 2 beego默认主键是id 如果主键定义的是其他字段比如userid 那么加上orm pk type User struct { Id int `orm:"pk;column(Userid);"` Name string }
beego 上传文件
package main import ( "github.com/astaxie/beego" ) type UploadController struct { beego.Controller } func (this *UploadController) Post() { this.SaveToFile("uploadfile", "./static/files/",true) this.Ctx.Redirect(302, "/upload") } /* * fromfile input type=file name=fromfile * tofilepath the path where the file going to save * newfilename boolen is create new name or use original name */ func (c *UploadController) SaveToFile(fromfile, tofilepath string, newfilename bool) error { file, h, err := c.Ctx.Request.FormFile(fromfile) if err != nil { return err } defer file.Close() newname := h.Filename if newfilename { newname = fmt.Sprintf("%v%s", time.Now().Unix(), path.Ext(h.Filename)) } tofilepath = path.Join(tofilepath, newname) f, err := os.OpenFile(tofilepath, os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0666) if err != nil { return err } defer f.Close() io.Copy(f, file) return nil } func main() {
beego.Router("/upload", &UploadController{}) beego.Run()
}
