问题描述
我正在尝试使用PHP来exec()二进制casperjs
I'm trying to use PHP to exec() a binary casperjs,
exec('casperjs /var/www/mysite/application/phantomjs/test.js');
但是我遇到了错误
Fatal: [Errno 2] No such file or directory; did you install phantomjs?
CasperJS在PhantomJS之上运行，我都手动安装并在/usr/local/bin/phantomjs和/usr/local/bin/casperjs上创建了一个链接.因此，我猜测casperjs在运行时会调用phantomjs.
CasperJS runs on top of PhantomJS, both which I manually installed and created a link at /usr/local/bin/phantomjs and /usr/local/bin/casperjs. So I am guessing casperjs calls phantomjs when it runs.
但是，当我SSH进入服务器并运行时，它工作正常
However it works fine when I ssh into the server and run
casperjs /var/www/mysite/application/phantomjs/test.js
出了什么问题?我认为casperjs无法以网络用户身份运行phantomjs吗?如果是这样，如何解决?
What went wrong? I think casperjs cannot run phantomjs as a web user? If this is true, how can it be fixed?
推荐答案
只需尝试使用程序的完整路径调用exec命令.例如
Just try to call the exec command with the full path of the program. For example
exec('/usr/local/bin/casperjs /var/www/mysite/application/phantomjs/test.js');
还要确保您被允许通过Web服务器执行该程序，尤其是如果您使用php safe_mode on.看看 safe_mode_exec_dir
Also make sure that you are allowed to execute that program via the web server, especially if you use the php safe_mode on. Have a look at safe_mode_exec_dir
