我一直在尝试使用https://github.com/WadeShuler/PHP-PayPal-IPN/集成IPN侦听器。我检查了一下,发现从IPN返回的变量都是空的,例如$ _POST ['payment_status']返回空,而$ _POST ['custom']返回空。我还从IPN侦听器检查了我的服务器日志,发现它有错误。
ipn-error.log
$ R --help
Usage: R [options] [< infile] [> outfile]
or: R CMD command [arguments]
Start R, a system for statistical computation and graphics, with the
specified options, or invoke an R tool via the 'R CMD' interface.
Options:
--no-environ Don't read the site and user environment files
--no-site-file Don't read the site-wide Rprofile
--no-init-file Don't read the user R profile
--vanilla Combine --no-save, --no-restore, --no-site-file,
--no-init-file and --no-environ
任何给予的帮助将不胜感激。
注意:所有这些操作都是在沙盒环境中完成的
