我有一个从守护服务器调用函数的脚本。守护进程服务器每次完成其作业时都会生成一个输出。守护进程主要从外部服务器下载文件。守护程序源代码已关闭(由外部公司编码)。你知道吗
完成文件下载后的守护程序输出示例:
Saved to /home/ubuntu/Daemon/downloads/download_1024000003.pdf
我使用的脚本从一个TXT文件中获取下载的id,from User字段的PC用户名,并将它们放入一个数组中,然后从守护进程中调用它们获取文件,然后在一个TXT文件中写入日志。你知道吗
日志样本应为:
Documnent ID= 3
From User = DomainCon
Saved to /home/ubuntu/Daemon/downloads/download_1024000003.pdf
我面临的问题是保存到/home/ubuntu/Daemon/downloads/download\u 1024000003.pdf中的文件有时会在TXT文件中丢失,每次下载完成后,Daemon服务器都会生成这个文件。你知道吗
问题示例:
Documnent ID= 2
From User = DomainCon
Documnent ID= 3
In Chat = DomainCon

Saved to /home/ubuntu/Daemon/downloads/download_1024000003.pdf
日志文件中的输出应为:
Documnent ID= 2
From User = DomainCon

这是我正在使用的脚本,包括注释:
for i in range(len(ids)):\\ ids is the array that contains the documents that should be downloaded.
cmdping = "sleep 5; echo load_document "+ids[i][0]+"| nc -w 4 127.0.0.1 1234 | tee >> "+logtxt \\ Perpare the Echo command to the daemon to start the download tee to save the output of the daemon into the log text
print("\033[1;31m~~~Documnent~~~NB~~~"+str(i+1)+"\033[1;m")
print ("Documnent ID= "+ids[i][0])\\ Just Print on screen for Debbuging Purpose
print ("From User= "+ids[i][1])\\Just Print on screen for Debbuging Purpose
logfile = open(logtxt, "a") \\ Open the TXT where the log is gonna be saved.
logfile.write("Documnent ID= "+ids[i][0]+"\n")\\Write the Document ID in the File.
logfile.write("From User = "+ids[i][1]+"\n")\\\\Write the From User in the File.
logfile.close()\\Close the logfile
if (i==len(ids)-1):
p=subprocess.Popen(cmdping, shell=True, stderr=subprocess.PIPE)\\ Start the proccess that was prepared before.
#time.sleep(1)
check=""
s=1
skip=0
while (s==1):
check=checkfile(srcdir)
if (check!="no"):
s=2
if(check=="skip"):
skip=1
if(skip!=1):
if(checksize(srcdir+check) == "done"):
print(check+"\n \033[1;32mFinished Downloading moving to the next download\033[1;m")
p.terminate()
user_dir=rootdir+"/document/"+ids[i][1];
checkandcopy(download,user_dir)
你可以考虑改用插座。以下是一些灵感:
