1、说明
multipart/form-data格式用于文件上传
gin文件上传与原生的net/http方法类似，不同在于gin把原生的request封装到c.Request中
2、实例代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<form action="http://localhost:8080/upload" method="post" enctype="multipart/form-data">
上传文件:<input type="file" name="file" >
<input type="submit" value="提交">
</form>
</body>
</html>
gin代码示例
package main
import (
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
//限制上传最大尺寸
r.MaxMultipartMemory = 8 << 20
r.POST("/upload", func(c *gin.Context) {
file, err := c.FormFile("file")
if err != nil {
c.String(500, "上传图片出错")
}
// c.JSON(200, gin.H{"message": file.Header.Context})
c.SaveUploadedFile(file, file.Filename)
c.String(http.StatusOK, file.Filename)
})
r.Run()
}
