在我的用例中,我试图将文件上传到 golang 中的服务器。我有以下html代码,
<div class="form-input upload-file" enctype="multipart/form-data" >
<input type="file"name="file" id="file" />
<input type="hidden"name="token" value="{{.}}" />
<a href="/uploadfile/" data-toggle="tooltip" title="upload">
<input type="button upload-video" class="btn btn-primary btn-filled btn-xs" value="upload" />
</a>
</div>
而服务器端,
func uploadHandler(w http.ResponseWriter, r *http.Request) {
// the FormFile function takes in the POST input id file
file, header, err := r.FormFile("file")
if err != nil {
fmt.Fprintln(w, err)
return
}
defer file.Close()
out, err := os.Create("/tmp/uploadedfile")
if err != nil {
fmt.Fprintf(w, "Unable to create the file for writing. Check your write access privilege")
return
}
defer out.Close()
// write the content from POST to the file
_, err = io.Copy(out, file)
if err != nil {
fmt.Fprintln(w, err)
}
fmt.Fprintf(w, "File uploaded successfully : ")
fmt.Fprintf(w, header.Filename)
}
当我尝试上传文件时,request Content-Type isn't multipart/form-data在服务器端出现错误。
有人可以帮我吗?
