启动Google App Engine Web服务器

Question

我将使用PHP(https://developers.google.com/appengine/docs/php/gettingstarted/helloworld)浏览Google App Engine的helloworld教程.在设置好应用程序并准备好之后,教程告诉我使用以下命令启动Google App Engine SDK附带的Web服务器:google_appengine/dev_appserver.py --php_executable_path = helloworld /.我该如何启动Web服务器以及将该命令放在何处？

Answer 1

在您的计算机上安装SDK后,您将拥有一个google_appengine目录.我运行Windows,因此我的位于:

C:\ Program Files(x86)\ Google\google_appengine

在该目录中是一个名为"dev_appserver.py"的python脚本,这是教程要求您运行的内容.您的本地计算机也应安装PHP,并且脚本正在查找该位置,因为它将是您自己安装的内容.

您将从您的操作系统的任何本地命令行应用程序(Linux的shell,Mac中的终端,Windows中的命令提示符或Powershell)中执行此脚本.

我从我的GAE应用程序上方一级存储的文件夹中执行我的操作.为确保您可以正确执行此命令,请在不带参数的情况下运行它,您应该看到:

python"C:\ Program Files(x86)\ Google\google_appengine\dev_appserver.py"

输出:

dev_appserver.py: error: too few arguments

让我们正常工作的命令是:

python "C:\Program Files (x86)\Google\google_appengine\dev_appserver.py" --port 8082 --admin_port 8083 --php_executable_path "C:\Program Files (x86)\NuSphere\PhpED\php54\php-cgi.exe" helloworld\

我在Powershell中得到了这个输出,并且能够点击当地的网址并看到"Hellow,World!"
