我已经安装了 sendmail 并希望将收到的电子邮件通过管道传输到 php。
每次我向我的服务器发送电子邮件时,我都会收到一封带有错误消息的电子邮件:
could not open input file: /root/fw/catcher.php 554 5.3.0 unknown mailer error 1
我认为具有 catcher.php
权限的内容是错误的,但我自己无法弄清楚。
Sendmail 已安装,我已添加别名:
root: "|/usr/bin/php /root/fw/catcher.php"
权限(在 chmod 777
之后;我尝试了 chmod 777
和 chmod 755
但都不起作用):
drwxrwxrwx 2 root root 4096 Jul 20 14:27 fw
-rwxrwxrwx 1 root root 45 Jul 20 14:27 catcher.php
catcher.php(将行尾转换为 Unix 风格):
#!/usr/bin/php
<?php echo 'Test'; exit(0); ?>
通过 cli 执行我的 php 文件工作正常。所有这些命令都有效:
/usr/bin/php /root/fw/catcher.php
/usr/bin/php7.3 /root/fw/catcher.php
php /root/fw/catcher.php
php7.3 /root/fw/catcher.php
我认为sendmail的权限有问题。
最佳答案
错误“无法打开输入文件”表示由于某种原因无法读取文件。
请按照以下步骤检查:
-
converted line endings to Unix style
我不知道你是如何检查这个的,但你可以尝试使用 dos2unix, as described in this link 重做这个
dos2unix catcher.php > newcatcher.php
然后比较文件大小。
- 可能是 BOM 破坏了脚本,如所述here , shebang 行 "#!/usr/bin/php" 告诉系统在调用这样的脚本时需要运行哪个解释器。
If the script is encoded in UTF-8, one may be tempted to include a BOM at the beginning. But actually the "#!" characters are not just characters. They are in fact a magic number that happens to be composed out of two ASCII characters. If you put something (like a BOM) before those characters, then the file will look like it had a different magic number and that can lead to problems.
脚本将通过 cli 运行,因为您明确告诉它要使用哪个解释器:php 或 php7.3:
php /root/fw/catcher.php
php7.3 /root/fw/catcher.php
要从文件开头删除 BOM,请尝试 this :
dos2unix catcher.php
尝试运行 /root/fw/catcher.php,作为 shell 脚本而不使用 php 或 php7.3 可执行文件。从终端运行:
./root/fw/catcher.php
