Question

我使用以下函数将mp4文件上传到ftp

 def run(self):
        while True:
            status = "Failed"
            #logger.debug("Queue size: %s" %(str(self.queue.qsize())))
            (env, pfile) = self.queue.get()
            logger.debug("Thread %s Received %s and %s" %(str(self.threadID), pfile, env))
            metaName = "%s/%s.evs.xml" %(self.config[env]["upload_folder"], pfile)
            mediaName = "%s/%s.mp4" %(self.config[env]["upload_folder"], pfile)
        mediaName2 = "%s.mp4" %(pfile,)     
            logger.info("Thread %s - Uploading metadata to %s FTP: %s" %(str(self.threadID), env, metaName))
            try:
                ur = uploadFTPMP(metaName, env)
        status = "Success"
            except:
                logger.debug("Thread %s - Uploading of metadata %s to %s failed" %(str(self.threadID), metaName, env))
                uploadComplete(pfile, status, env)
            if status == "Success": 
                logger.info("Thread %s - Sleeping to allow cms to pick up xml" %(str(self.threadID)))
                time.sleep(90)
                logger.info( "Thread %s - Uploading mediafile %s to %s" %(str(self.threadID), mediaName, env))
        ur = uploadFTP(mediaName, env)
                status = "Success"
        filename = os.path.basename(mediaName)
        http_client.HTTPConnection.debuglevel = 1
        logging.basicConfig(level=logging.INFO)
        logging.basicConfig()
        logging.getLogger().setLevel(logging.INFO)
        requests_log = logging.getLogger("requests.packages.urllib3")
        requests_log.setLevel(logging.INFO)
        requests_log.propagate = True
        url = 'http://www.webdev.com/web/home/testPOST'
        headers = {'content-type': 'application/json'}
        payload = {'mediaName': mediaName2 ,'status': 'sucsses'}
        r = requests.post(url, data=json.dumps(payload), headers=headers)
        r.text
        r.status_code
            r.connection.close()
                uploadComplete(pfile, status, env)
            logger.info("Thread %s - Upload completed with status %s" %(str(self.threadID), status))
            self.queue.task_done()

我正在尝试在上传之前修改mp4文件，时间戳到文件末尾，因此文件名将为video-%H%M%S.mp4，然后将上传。

然后，当我执行post请求时，如你所见，它现在发送2个参数，我需要添加第3个参数，这是带有时间戳的新名称。任何实现这种逻辑的技巧？

这也是我的ftp功能。

def uploadFTPMP(filepath, env):

    global config

    ftpsrv = config[env]["active"]
    ftpusr = config[env]["ftpuser"]
    ftppwd = config[env]["ftppass"]

    filename = os.path.basename(filepath)

    try:
        ftp = ftplib.FTP(ftpsrv)
        ftp.login(ftpusr, ftppwd)
    except:
        logger.error("Ftp connection error has occurred")
        raise 
    else:
        f = open(filepath, "r")
        cmd = "STOR %s" %(filename)
        out = ftp.storbinary(cmd, f)
        f.close()
        ftp.quit()
        return out

您应该将日期时间传递给文件名。

import datetime

medianame = 'somefile_{timestamp}.mp4'.format(
    timestamp=datetime.datetime.now().isoformat()
)

日期时间也可以根据需要进行格式化，例如datetime.datetime.now().strftime('%Y-%m-%d_%H%M')。 strftime() documentation 有一个可以使用的已接受格式化指令列表。

在上传到ftp之前，将时间戳添加到文件名末尾
