我在CentOS上使用CutyCapt.
它通过终端工作正常,但它不能通过
PHP exec功能.
我在终端启动了xvfb命令:
Xvfb :99 -screen 0 1024x768x24
我试图通过php脚本做截图:
exec("DISPLAY=:99 /path/to/cutycapt --url=<some url> --out=<path/to/output>");
它没有显示任何错误,但没有输出文件(输出目录有chmod 777)
有人能帮助我吗?
谢谢
UPD:
也许以某种方式允许Apache执行Xvfb更好?
最佳答案 我设法让CutyCapt在最后使用php成功运行. $_parameters通过AJAX传递给php脚本.希望这可以帮助…
