我用其他伪代码测试了我的ftp服务器，它工作正常，这里是我的函数。。在

上传功能在这里：

def upload(ifn):
    """ Upload Function."""

    create_time = datetime.now().strftime("%Y/%m/%d")

    ifn_norm = resub('[ !@#$%\t"#$%&\()*\-/<=>?@^_`{|},.:]', '-', ifn).lower() + os.path.splitext(ifn)[1]

    src = "%s/%s" % (src_loc,ifn)
    dst = "%s/%s" % (dst_loc, ifn_norm)

    s3_dst = "%s/%s" % (create_time,ifn_norm)
    trans_dst = "%s/%s" % (proc_loc,ifn_norm)

    start_time = time.time()

    try:
        transcode(src,trans_dst)
    except:
        return
    trans_time = time.time() - start_time
    try:
        upload_to_ftp(trans_dst,s3_dst)
        # post request will be performed if no exception will raise in upload_to_ftp method

        # parameters for this call should be set in config file, because i don't know the url
        perform_post_req(trans_dst,s3_dst)

    except NameError as s3error:
        logger.error("Upload failed for %s , with exception %s" % (trans_dst, s3error))
        oflist.remove(ifn)
        hsize.pop(ifn)
        return

    upload_time = (time.time() - start_time) - trans_time

    logger.info("Uploading completed for %s, stats - transcode time : %.3f seconds, upload time : %.3f seconds" %(ifn,trans_time,upload_time))
    logger.info("Moving \"%s\" to \"%s\"" % (trans_dst, dst))
    rc = os.system("mv \"%s\" \"%s\"" %(trans_dst, dst))
    if rc != 0:
        logger.error("Can't move file %s - Exiting" %(trans_dst))
    else:
        logger.info("Moved file %s" %(trans_dst))
        oflist.remove(ifn)
        hsize.pop(ifn)
    return

ftp服务器工作正常，经过测试

你能给我个建议吗

根据函数upload_to_ftp定义，它期望服务器ip作为第二个参数。在

但在调用部分，文件（或目录）路径被传递。在

upload_to_ftp(trans_dst,s3_dst)
                        ^^^^^^

用服务器ip更改s3_dst。在
