EOFError:仅在通过curl执行行时读取行时的EOF

Question

我有一段python代码，它根据URL和来自用户输入的数据构造CURL命令

我有过

import os

print ("______________\n")
print "   1.GET         "
print "   2.POST        "
print "   3.PUT         "
print "   4.DELETE      "
print ("______________\n")


http = int(raw_input("Select your option : "))

url = raw_input("Paste Your URL : ")

if not http:
    http = 3

if http == 1:
    cmd = 'curl '+ url
elif http == 2:
    data = raw_input("Paste Your Data : ")
    cmd = 'curl -g -X POST -H "Content-Type:application/json" -d \''+data+'\' ' + url
elif http == 3:
    data = raw_input("Paste Your JSON Data: ")
    cmd = 'curl -g -X PUT -H "Content-Type:application/json" -d \''+data+'\' ' + url
else:
    cmd = 'curl -g -X DELETE ' + url

print ("_________________________________________\n")
print '\n'
print cmd
print '\n'
print ("_________________________________________\n")


run = raw_input("Do you want to run it ? [y/n]: ")
print '\n'
if run == 'y':
    os.system(cmd+'\n')
    print '\n'
else:
    os.system("clear")
    sys.exit()

我在运行它

python get_curl.py

我得到了

______________

   1.GET         
   2.POST        
   3.PUT         
   4.DELETE      
______________

Select your option : 3
Paste Your URL : http://172.19.242.32:1234/vse/vcpe/002233445567/vlan/104/device/000011223350/duration
Paste Your Data : {"acl_mode": 2, "portal_url": "http://localhost:8888/captive-portal?client_mac=$MAC&ap=$AP-MAC", "duration": 120 }
_________________________________________



curl -g -X PUT -H "Content-Type:application/json" -d '{"acl_mode": 2, "portal_url": "http://localhost:8888/captive-portal?client_mac=$MAC&ap=$AP-MAC", "duration": 120 }' http://172.19.242.32:1234/vse/vcpe/002233445567/vlan/104/device/000011223350/duration


_________________________________________

Do you want to run it ? [y/n]: y
{ "status": 201, "message": "Processed cpe HNS device duration message" }

然后，我把它托管在github gist上，这样我就可以分享它了

执行要点

结果

______________

   1.GET         
   2.POST        
   3.PUT         
   4.DELETE      
______________

Select your option : Traceback (most recent call last):
  File "<stdin>", line 11, in <module>
EOFError: EOF when reading a line

为什么我在本地Mac上运行时会有不同的结果？

我该如何预防呢？

Answer 1

由于您通过管道将curl命令传递给python，因此将标准输入连接到管道，而不是用户的终端。

您可以使用bash process substitution使curl命令显示为文件名参数，而不是从标准输入中读取它。

python <(curl "https://gist.githubusercontent.com/bheng/b23d775ee7b106cd7cc0ae5ac71b81a9/raw/c6ecd3ed7bc04699d73e1b9ed521f481ac6a41c4/get_curl.py" -s -N)

Answer 2

在python等待输入时，管道正在发送行。最好做一些像这样的事情

curl "https://gist.githubusercontent.com/bheng/b23d775ee7b106cd7cc0ae5ac71b81a9/raw/c6ecd3ed7bc04699d73e1b9ed521f481ac6a41c4/get_curl.py" -s -N > myscript; python myscript
