上傳單個檔案、上傳多個檔案

1、上傳單個文
views
beego 中 上 傳 圖 片 是 非 常 簡 單 的 ， 但 是 要 注 意 的 是 form 表 單 中 必 須 加 入 enctype="multipart/form-data"這個屬性，否則你的瀏覽器不會傳輸你上傳的檔案。
article.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Article</title>
</head>
<body>
<h2>上傳文章</h2>
<form method="post" action="/article/doUpload" enctype="multipart/form-data">
標題: <input type="text" name="title" /> <br><br>
內容: <input type="text" name="content" />
<br><br>
檔案：<input type="file" name="pic" />
<br><br>
<input type="submit" value="提交">
</form>
</body>
</html>routers
package routers
import (
"beegoupload/controllers"
"github.com/astaxie/beego"
)
func init() {
beego.Router("/", &controllers.MainController{})
beego.Router("/focus", &controllers.FocusController{})
beego.Router("/focus/doUpload", &controllers.FocusController{}, "post:DoUpload")
beego.Router("/article", &controllers.ArticleController{})
beego.Router("/article/doUpload", &controllers.ArticleController{}, "post:DoUpload")
}controllers
GetFile 可以接受傳過來的圖片和檔案
package controllers
import (
"github.com/astaxie/beego"
)
type ArticleController struct {
beego.Controller
}
func (c *ArticleController) Get() {
c.TplName = "article.html"
}
func (c *ArticleController) DoUpload() {
title := c.GetString("title")
content := c.GetString("content")
beego.Info(title)
beego.Info(content)
//執行上傳檔案
f, h, err := c.GetFile("pic")
if err != nil {
beego.Error(err)
c.Ctx.WriteString("上傳檔案失敗")
return
}
c.SaveToFile("pic", "static/upload/"+h.Filename) //目錄必須提前建立好
//關閉檔案流
defer f.Close()
c.Ctx.WriteString("上傳檔案成功")
}
2、上傳多個檔案
focus.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Focus</title>
</head>
<body>
<h2>上傳輪播圖</h2>
<form method="post" action="/focus/doUpload" enctype="multipart/form-data">
標題: <input type="text" name="title" />
<br><br>
檔案1：<input type="file" name="pic1" /><br><br>
檔案2：<input type="file" name="pic2" />
<br><br>
<input type="submit" value="提交">
</form>
</body>
</html>
package controllers
import (
"github.com/astaxie/beego"
)
type FocusController struct {
beego.Controller
}
func (c *FocusController) Get() {
c.TplName = "focus.html"
}
func (c *FocusController) DoUpload() {
title := c.GetString("title")
beego.Info(title)
//接收第一個檔案
f1, h1, err1 := c.GetFile("pic1")
if err1 != nil {
beego.Warning(err1)
} else {
//關閉檔案流
defer f1.Close()
c.SaveToFile("pic1", "static/upload/"+h1.Filename)
}
//接收第二個檔案
f2, h2, err2 := c.GetFile("pic2")
if err2 != nil {
beego.Warning(err2)
} else {
defer f2.Close()
c.SaveToFile("pic2", "static/upload/"+h2.Filename)
}
c.Ctx.WriteString("上傳檔案成功")
}
