Single file

References issue #774 and detail example code.

file.Filename SHOULD NOT be trusted. See Content-Disposition on MDN and #1693

The filename is always optional and must not be used blindly by the application: path information should be stripped, and conversion to the server file system rules should be done.

  1. func main() {
  2.     router := gin.Default()
  3.     // Set a lower memory limit for multipart forms (default is 32 MiB)
  4.     router.MaxMultipartMemory = 8 << 20  // 8 MiB
  5.     router.POST("/upload", func(c *gin.Context) {
  6.         // single file
  7.         file, _ := c.FormFile("file")
  8.         log.Println(file.Filename)
  10.         // Upload the file to specific dst.
  11.         c.SaveUploadedFile(file, dst)
  13.         c.String(http.StatusOK, fmt.Sprintf("'%s' uploaded!", file.Filename))
  14.     })
  15.     router.Run(":8080")
  16. }

How to curl:

  1. curl -X POST http://localhost:8080/upload \
  2.   -F "file=@/Users/appleboy/test.zip" \
  3.   -H "Content-Type: multipart/form-data"
