子进程Python中的curl问题 [英] Curl issue in subprocess Python

问题描述

当我尝试在命令行上运行以下命令时，我获得了存储大小。

  curl -G  - dkey = val'http://172.16.26.2:9005/as/system/storage'
 {
userQuotaMax：675048，
userQuotaUsed：439191 
} 
  

如果我尝试在我的python脚本中运行，数据。

  arg_list = curl -G -dkey = val'http://172.16.26.2:9005/as / system / storage'
 
p = Popen（arg_list，shell = True，stdin = PIPE，stdout = PIPE，stderr = STDOUT，executable ='/ bin / bash'）
 $ b b output = p.stdout.read（）
 
打印输出
  

解决方案

而不是使用popen（）调用curl，你可能更适合使用请求。 / p>

http：/ /docs.python-requests.org/en/master/user/quickstart/

这样的东西）：

 导入请求
 
 payload = {key：val} 
 
 response = requests.get（http://172.16.26.2:9005/as/system/storage，data = payload）
 
 print（response.text）
  

所以像（POST）：

 导入请求
 
 payload = {key：val} 
 
 response = requests.post （http://172.16.26.2:9005/as/system/storage，data = payload）
 
 print（response.text）
  

应该返回（假设api返回html / text，如果它返回JSON，看看response.json在以上链接）：

  {
userQuotaMax：675048，
userQuotaUsed：439191 
} 
  

希望这可以帮助你

When I tried to run the following command on the command line, I get the storage size.

curl -G -d "key=val" 'http://172.16.26.2:9005/as/system/storage'
    {
       "userQuotaMax" : 675048,
       "userQuotaUsed" : 439191
    }

If I try to run in my python script, Then, I can'not get the same data.

arg_list = curl -G -d "key=val" 'http://172.16.26.2:9005/as/system/storage'

p = Popen(arg_list, shell=True, stdin=PIPE, stdout=PIPE, stderr=STDOUT, executable='/bin/bash')

output = p.stdout.read()

print output

Any helps would be really appreciated.

解决方案

Instead of calling curl using popen(), you might be better served by using requests.

http://docs.python-requests.org/en/master/user/quickstart/

so something like (for GET):

import requests

payload = {"key" :"val"}

response = requests.get("http://172.16.26.2:9005/as/system/storage", data=payload)

print(response.text)

so something like (for POST):

import requests

payload = {"key" :"val"}

response = requests.post("http://172.16.26.2:9005/as/system/storage", data=payload)

print(response.text)

Should return (assuming the api returns html/text, if it returns JSON, have a look at response.json() explained at the link above):

{
   "userQuotaMax" : 675048,
   "userQuotaUsed" : 439191
}

Hope this helps you
