我有以下功能:
func (rc ResizeController) Resize(c *gin.Context) {
height := c.Query("height")
width := c.Query("width")
filepath := c.Query("file")
h, err := strconv.ParseUint(height, 10, 32)
w, err := strconv.ParseUint(width, 10, 32)
file, err := os.Open("./test_images/" + filepath)
if err != nil {
log.Fatal(err)
}
image, err := jpeg.Decode(file)
if err != nil {
log.Fatal(err)
}
m := resize.Resize(1000, 100, image, resize.Lanczos3)
buf := new(bytes.Buffer)
jpeg.Encode(buf, m, nil)
response := buf.Bytes()
c.Data(200, "image/jpeg", response)
}
但我收到以下错误:
controllers/resize_controller.go:41: cannot use h (type uint64) as type uint in argument to resize.Resize
controllers/resize_controller.go:41: cannot use w (type uint64) as type uint in argument to resize.Resize
我已经尝试了 strconv lib 中的一些不同功能,但没有成功!
