In my application users creating articles and adding images to it if user wont add a image, that application must search for it in google images and add that image to user article. But when i tried to get image from google. Im get this error:

     AbstractDecoder.php line 302:
Image source not readable

Controller Method:

 public function store(ArticleRequest $request)
    {
        if ($request->hasFile('file')) {

            $file = Input::file('file');
            $imgTitle = $request->title;
            $imagePath = 'uploads/' . $imgTitle . '.jpg';
            $request->image_path = $imagePath;

            Article::create(array('title' => $request->title,
                'body' => $request->body,
                'image_path' => $imagePath));

            Image::make($file)->resize(300, 200)->save($imagePath);
        } else {
//            $file = Input::file('file');
            $imgTitle = $request->title;

            $query = $imgTitle;

            $ch = curl_init();

            curl_setopt($ch, CURLOPT_URL, "https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=" . urlencode($query));

            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

            $output = json_decode(curl_exec($ch));

//            $file = file_get_contents($output);
            curl_close($ch);

            $imagePath = 'uploads/' . $imgTitle . '.jpg';

            $request->image_path = $imagePath;
            Article::create(array('title' => $request->title,
                'body' => $request->body,
                'image_path' => $imagePath));

            Image::make($output)->resize(300, 200)->save($imagePath);

        }

    }

解决方案

$output = json_decode(curl_exec($ch));

Returns a json object with the results. If you want to get the first image url add

$output = json_decode(curl_exec($ch));
if(!empty($responseData->results))
    $output = $output->responseData->results[0]->url;
else {
    die('no image found');
}
