DownloadFile error strconv.ParseInt: parsing "": invalid syntax #47
Description
相关代码如下：
func (u *UFileRequest) DownloadFile(writer io.Writer, keyName string) error {
reqURL := u.GetPrivateURL(keyName, 24*time.Hour)
req, err := http.NewRequest("GET", reqURL, nil)
if err != nil {
return err
}
resp, err := u.requestWithResp(req)
if err != nil {
return err
}
defer resp.Body.Close()
u.LastResponseStatus = resp.StatusCode
u.LastResponseHeader = resp.Header
u.LastResponseBody = nil //流式下载无body存储在u里
u.lastResponse = resp
if !VerifyHTTPCode(resp.StatusCode) {
return fmt.Errorf("Remote response code is %d - %s not 2xx call DumpResponse(true) show details",
resp.StatusCode, http.StatusText(resp.StatusCode))
}
size := u.LastResponseHeader.Get("Content-Length")
fileSize, err := strconv.ParseInt(size, 10, 0)
if err != nil || fileSize < 0 {
return fmt.Errorf("Parse content-lengt returned error")
}
_, err = io.Copy(writer, resp.Body)
return err
}由于size := u.LastResponseHeader.Get("Content-Length") 获取不到 length 导致后续 _, err = io.Copy(writer, resp.Body) 没执行，下载文件失败。
请确认是新版API不返回 Length 属性了？还是 SDK 需要更新
