我正在尝试使用多部分表单将音频文件上传到 Golang 服务器。但是，Go 返回错误：
multipart: NextPart: bufio: buffer full
我相信这表明我的 Javascript 请求中没有多部分格式的内容。这是我的Javascript：
function UploadFile(file) {
var xhr = new XMLHttpRequest();
if (file.type == "audio/mpeg" && file.size <= $id("MAX_FILE_SIZE").value) {
// start upload
var boundary = '---------------------------' + Math.floor(Math.random()*32768) + Math.floor(Math.random()*32768) + Math.floor(Math.random()*32768);
xhr.open("POST", $id("upload").action, true);
xhr.setRequestHeader("Content-Type", "multipart/form-data; boundary=" + boundary);
xhr.setRequestHeader("X_FILENAME", file.name);
xhr.send(file);
}
}
这是我的 Golang 服务器处理程序：
func FileHandler(w http.ResponseWriter, r *http.Request) {
var (
status int
err error
)
defer func() {
if nil != err {
http.Error(w, err.Error(), status)
}
}()
// parse request with maximum memory of _24Kilobits
const _24K = (1 << 20) * 24
if err = r.ParseMultipartForm(_24K); nil != err {
fmt.Println(err)
status = http.StatusInternalServerError
return
}
for _, fheaders := range r.MultipartForm.File {
for _, hdr := range fheaders {
// open uploaded
var infile multipart.File
if infile, err = hdr.Open(); nil != err {
status = http.StatusInternalServerError
return
}
// open destination
var outfile *os.File
if outfile, err = os.Create("./uploaded/" + hdr.Filename); nil != err {
status = http.StatusInternalServerError
return
}
// 32K buffer copy
var written int64
if written, err = io.Copy(outfile, infile); nil != err {
status = http.StatusInternalServerError
return
}
}
}
}
如果有人对我收到此错误的原因有任何想法，我将不胜感激。
