在命令中显示进度条的方式如下:
use Symfony'Component'Console'Helper'ProgressBar;
$progress = new ProgressBar($output, 50);
$progress->start();
$i = 0;
while ($i++ < 50) {
$progress->advance();
}
$progress->finish()
但是如果你只有一个调用服务的命令:
// command file
$this->getContainer()->get('update.product.countries')->update();
// service file
public function update()
{
$validCountryCodes = $this->countryRepository->findAll();
$products = $this->productRepository->findWithInvalidCountryCode($validCountryCodes);
foreach ($products as $product) {
...
}
}
是否可以在服务foreach循环中以类似于命令文件中的方式输出进度?
您需要以某种方式修改该方法。下面是一个例子:
public function update('Closure $callback = null)
{
$validCountryCodes = $this->countryRepository->findAll();
$products = $this->productRepository->findWithInvalidCountryCode($validCountryCodes);
foreach ($products as $product) {
if ($callback) {
$callback($product);
}
...
}
}
/**
* command file
*/
public function execute(InputInterface $input, OutputInterface $output)
{
$progress = new ProgressBar($output, 50);
$progress->start();
$callback = function ($product) use ($progress) {
$progress->advance();
};
$this->getContainer()->get('update.product.countries')->update($callback);
}
