Question

在运行Raspian，Apache服务器的Pi3上，我有一个Django应用。

我正在尝试从Django运行python文件。
如果我通过SSH进入我的Pi并输入“ python test_data.py”，则可以正常运行。我以“ pi”用户身份登录

test_data.py就是这样。

output = "success!"
print(output)

urls.py

url(r'^mygame/$', views.my_game),

views.py 文件，我具有以下

from subprocess import PIPE, run

def my_game(request):
    command = ['sudo', 'python test_data.py']
    result = run(command, stdout=PIPE, stderr=PIPE, shell=True, universal_newlines=True)
    return render(request, 'rungame.html',{'data1':result})

通过网络浏览器调用/ mygame时，这是我在rungame.html中打印的结果，所以我知道它称为test_data.py。看来是权限问题？我不明白以下含义。有人可以告知这是否是权限问题，如何解决？

CompletedProcess(args=['sudo', 'python mygame.py'], returncode=1, stdout='', stderr='usage: sudo -h | -K | -k | -V\
nusage: sudo -v [-AknS] [-g group] [-h host] [-p prompt] [-u user]\
nusage: sudo -l [-AknS] [-g group] [-h host] [-p prompt] [-U user] [-u user]\n [command]\
nusage: sudo [-AbEHknPS] [-r role] [-t type] [-C num] [-g group] [-h host] [-p\n prompt] [-u user] [VAR=value] [-i|-s] [<command>]\
nusage: sudo -e [-AknS] [-r role] [-t type] [-C num] [-g group] [-h host] [-p\n prompt] [-u user] file ...\n')

谢谢

添加的信息：创建mygame.py来测试概念

import pygame
import sys

pygame.init()

WIDTH = 800
HEIGHT = 600

screen = pygame.display.set_mode((WIDTH, HEIGHT))
background = pygame.image.load('background1.png')


print("test")
game_over = False

while not game_over:
    screen.blit(background, (0, 0))
    pygame.display.update()
    for event in pygame.event.get():
        print(event)
        if event.type == pygame.QUIT:
            sys.exit()

这是我的APACHE CONF文件

不要使用子进程来调用脚本。您有一个python脚本，使其成为一个函数并将其导入Django。然后在您的views.py中调用该函数。

test_data.py

void OnTick()
{

    string signal = "";
    double Sar = iSAR(_Symbol, _Period, 0.02, 0.2, 0);

    if (Sar < Low[1] && Open[1] < Close[1])
    {
        signal = "buy";
    }

    if (Sar > High[1] && Open[1] > Close[1])
    {
        signal = "sell";
    }

    if (signal == "buy" && OrdersTotal() == 0)

        OrderSend(_Symbol, OP_BUY, 0.01, Ask, 3, 20, 100, NULL, 0, 0, Green);

    if (signal == "sell" && OrdersTotal() == 0)

        OrderSend(_Symbol, OP_SELL, 0.01, Bid, 3, 20, 100, NULL, 0, 0, Red);

    Comment("The Signal is :", signal);

    if (Open[1] > Close[1] && OrdersTotal() > 0)

        CloseBuyPosition();

    if (Open[1] < Close[1] && OrdersTotal() > 0)

        CloseSellPosition();
}

views.py

def my_function():
    output = "success!"
    return output

将 test_data.py 脚本与 views.py 放在同一目录中。

从Django远程运行pygame脚本
