php - Composer 脚本中的用户输入

Question

在 composer 包中我有 post-install-cmd 脚本，像这样:

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

但是在 composer install 之后我得到了这个错误:

...
Generating autoload files
> post-install-cmd: _scripts/ask_db_data.sh
Executing command (CWD): _scripts/ask_db_data.sh
Hello!
Script _scripts/ask_db_data.sh handling the post-install-cmd event returned with an error


[RuntimeException]

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给您的 php 文件。我不确定，为什么那行不通。

另一种方法是保留在 post-install-cmd 的 PHP 代码中。 那是一个事件，它可以访问 Composer 和 IO。 要使用控制台，您需要来自 Composer 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“缺失”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));
