当我访问时：http://X.X.X.X/html_machine_info/,I发现all_machine_info func没有执行，但我使用
#python manage.py shell
>>> from birdman.views import all_machine_info
>>> all_machine_info()
它确实执行，为什么？因为与线程有关？

挖掘你的源代码，似乎你正在开始新的线程，而不是真正等待它们完成。试试这样的事情
def all_machine_info():
f = open(server_list)
lines = f.readlines()
jobs = [] # List of background jobs
for ip in lines:
a = threading.Thread(target = machine_info,args = (ip,))
a.start()
jobs.append(a)
for a in jobs:
a.join() # Wait for job to finish
f.close()
