Question

我使用ftp上传功能将文件上传到我自己的ftp服务器，除了以下内容之外，还要保留以下内容，

2015-12-10 11:35:22,985 - FtpUpload - Failed to setup connection
Exception in thread Thread-1:

我已经用其他虚拟代码测试了我的ftp服务器并且工作正常，这是我的功能..

def upload_to_ftp(file_path, server_ip):
    try:
        #connection
        _ftp = ftplib.FTP()
        _ftp.connect(server_ip, port)
        #user and password vars must be in the config file
        _ftp.login(user=user, password=password)
        logger.info("Connecting to ftp server...")
    except:
        logger.error("Failed to setup connection")
        raise
    logger.info("Starting to upload %s to %s" % (file_path, server_ip))
    upload_file = open(file_path, 'r')
    try:
        path_split = file_path.split('/')
        file_name = path_split[len(path_split) - 1]

        _ftp.storbinary('STOR '+ file_path, upload_file, 1024)
        logger.info("File %s is uploaded." % file_path)
        upload_file.close()
    except:
        logger.error("Upload to FTP failed")
        upload_file.close()

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，一路测试，

你能告诉你吗

Answer 1

根据函数upload_to_ftp定义，它期望服务器ip作为第二个参数。

但是在调用部分中，传递了文件（或目录）路径。

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

使用服务器IP更改s3_dst。
