作曲家脚本中的用户输入

Question

在composer包中，我有安装后的cmd脚本，如下所示：

#!/bin/bash
echo 'Hello!'
read -p 'Database password: ' DB_PASS
php setup/index.php database_password=$DB_PASS
echo 'Complete!'

但在composer install之后，我得到了这个错误：

...

如何在composer脚本中请求用户输入？

Answer 1

好的，您正在尝试执行bash/shell脚本来读取字符串并将其传递到php文件。我不确定，为什么不成功。

另一种选择是留在post-install-cmd的PHP代码中。这是一个事件，它可以访问Composer和IO。要使用Console，您需要Composer中的$io对象。您可以使用getIO()获取它。

然后，您可以使用方法ask()或askConfirmation()以交互方式询问用户"缺少"的值。

非常简短：

$io = $this->getIO();
$user = $io->ask('Enter your Username: ');
/// Its better not displaying the password:
$pw = $io->askAndHideAnswer('Enter your Password: ');
exec('php setup/index.php database_password=' . escapeshellarg($pw));

Answer 2

获取用户输入的一种方法是将数据放入文件中，并在bash脚本中读取：

#!/bin/bash
source .env
