【问题描述】:
我有一个允许用户创建愿望的应用程序。我使用每个希望的标题来发出 api 请求以取消启动以下载图片。我现在有一个问题,用户可以输入一个不从 unsplash 返回任何图像的标题。在这种情况下,我想使用占位符图像,但我的代码在收到 404 错误后停止。有没有办法忽略这个错误并继续我的循环?
public function fetchImagesFromUnsplash() {
$wishes = $this->repository->findAll();
foreach ($wishes as $wish) {
try {
$response = $this->httpClient->request('GET', 'https://api.unsplash.com/photos/random', [
'query' => [
'query' => $wish->getDescription(),
'client_id' => 'oa1DsGebE8ehCV9SrvcA1mCx-2QfvnufUKgsIY5N0Mk'
]
]);
} catch (TransportExceptionInterface $e) {
}
if ($response) {
$data = $response->getContent();
$data = json_decode($data, true);
$imageLink = $data['urls']['raw'];
$rawImage = file_get_contents($imageLink);
if ($rawImage) {
file_put_contents("public/images/" . sprintf('imageWish%d.jpg', $wish->getId()), $rawImage);
$wish->setImagePath(sprintf('public/images/imageWish%d.jpg', $wish->getId()));
} else {
$wish->setImagePath('placeholder.png');
}
$this->em->flush();
}
}
}
编辑:
我试过了:
public function fetchImagesFromUnsplash() {
$wishes = $this->repository->findAll();
foreach ($wishes as $wish) {
try {
$response = $this->httpClient->request('GET', 'https://api.unsplash.com/photos/random', [
'query' => [
'query' => $wish->getDescription(),
'client_id' => 'oa1DsGebE8ehCV9SrvcA1mCx-2QfvnufUKgsIY5N0Mk'
]
]);
} catch (NotFoundHttpException $e) {
}
if ($response) {
$data = $response->getContent();
$data = json_decode($data, true);
$imageLink = $data['urls']['raw'];
$rawImage = file_get_contents($imageLink);
if ($rawImage) {
file_put_contents("public/images/" . sprintf('imageWish%d.jpg', $wish->getId()), $rawImage);
$wish->setImagePath(sprintf('public/images/imageWish%d.jpg', $wish->getId()));
} else {
$wish->setImagePath('placeholder.png');
}
}
}
$this->em->flush();
}
但在第一个 404 之后它仍然停止
