一、使用Postman中form-data方式：

package main

import (
    "fmt"
    "github.com/gin-gonic/gin"
    "net/http"
    "time"
)

func upload360(c *gin.Context) {
    bit := c.PostForm("bit")
    fmt.Println(bit)
    file,err := c.FormFile("file")
    if err != nil {
        c.JSON(http.StatusBadRequest,gin.H{
            "message":"a Bad request!",
        })
        return
    }
    nowTime := string([]rune(time.Now().String())[0:10])
    if err := c.SaveUploadedFile(file,"F:\\Upload360\\360Update"+nowTime+"_"+bit+".exe"); err != nil {
        c.JSON(http.StatusOK,gin.H{
            "message":err,
        })
        return
    }
    c.JSON(http.StatusOK,gin.H{
        "message":"upload successful",
    })
}
func main() {
    router := gin.Default()
    router.POST("/upload",upload360)
    router.Run(":8899")
}

二、使用Postman中binary或者form-data方式：

package main

import (
    "fmt"
    "io"
    "net/http"
    "os"
    "time"
)

func uploadHandler(w http.ResponseWriter, r *http.Request) {
    nowTime := string([]rune(time.Now().String())[0:10])
    file, err := os.Create("F:\\Upload360\\360Update"+nowTime+".exe")
    if err != nil {
        panic(err)
    }
    _, err = io.Copy(file, r.Body)
    if err != nil {
        panic(err)
    }
    w.Write([]byte("upload success"))
}

func main() {
    fmt.Println("Start...")
    http.HandleFunc("/upload", uploadHandler)
    http.ListenAndServe(":8899", nil)
}
