問題描述
我每 6 秒將值附加到日志文件中.每 30 秒，我將此日志作為文件傳輸到 FTP 服務器.但不是傳輸整個文件，我只想將收集到的數據附加到我服務器上的文件中.我無法弄清楚如何打開服務器文件然后附加值.
I'm appending values to a log file every 6th second. Every 30 sec I'm transferring this log to an FTP server as a file. But instead of transfering the whole file, I just want to append the collected data to the file on my server. I haven't been able to figure out how to open the server file and then append the values.
到目前為止我的代碼:
session = ftplib.FTP(authData[0],authData[1],authData[2])
session.cwd("//"+serverCatalog()+"//") # open server catalog
file = open(fileName(),'rb')
with open(fileName(), 'rb') as f:
f = f.readlines()
for line in f:
collected = line
# In some way open server file, write lines to it
session.storbinary('STOR ' + fileName(), open(fileName(), 'a'), 1024)
file.close()
session.quit()
相反，我是否必須下載打開并附加的服務器文件，然后將其發回?
Instead, do I have to download the server file open and append, then send it back?
以上是我的問題，完整的解決方案如下:
Above was my question, the full solution is below:
session.cwd("//"+serverCatalog()+"//") # open server catalog
localfile = open("logfile.txt",'rb')
session.storbinary('APPE serverfile.txt', localfile)
localfile.close()
推薦答案
使用 APPE 而不是 STOR.
