API返回带有Guzzle的PNG图像 - API return PNG image with Guzzle

我正在向Box.com发送一个API请求，以获取PNG图像的缩略图。我在用拉拉威尔。当我使用以下代码时，我得到了要转换PNG图像的原始字符串数据。

$client = new Client('https://api.box.com/{version}/files/{file_id}', [
            'version' => '2.0',
            'file_id' => $id,
            'request.options' => [
                'headers' => [
                    'Authorization' => 'Bearer ' . self::getAccessToken(),
                ]
            ]
        ]);
        $request = $client->get('thumbnail.png?min_height=256&min_width=256');
        try {
            $response = $request->send();
            dd($response->getBody(true));

在不返回getBody()方法字符串的情况下，我什么都得不到，因为Box.com将在正文中返回缩略图的内容。

下面是我得到的字符串示例：

我得到了图像作为唯一字符串值的成功响应

$response = $this->client->request('GET', '/ap/generate-example/qr/image', [
                'headers' => [
                    'Content-Type' => 'application/json',
                    'user_name' => 'user_name',
                    'password' => 'password',
                    'Authorization' => "Bearer assdadga",
                    'width' => '300',
                    'height' => '300',
                    'imgtype' => 'jpg'
                ],
                // 'sink' => '/uploads/images'
            ]);
$body = $response->getBody();
$base64 = base64_encode($body);
$mime = "image/jpeg";
$img = ('data:' . $mime . ';base64,' . $base64);
dd($img);

输出：data:image/jpeg;base64,/9j/4AAQSkZJRgABAgAAAQABAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8UHRofHh0aHBwgJC4nICIsIxwcKDcpLDAxNDQ0Hyc5PTgyPC4zNDL/wAALCADcANwBAREA/8QAHwAAAQUBAQEBAQEAAAAAAAAAAAECAwQFBgcICQoL/8QAtRAAAgEDAwIEAwUFBAQAAAF9AQIDAAQRBRIhMUEGE1FhByJxFDKBkaE

让我们一起来看<img src="data:image/jpeg;base64,/9j/4AAQSkZJRgABAgAAAQA" />

我自己已经在Laravel 5.1上使用Guzzle3解决了这个问题。以下是相关代码，我希望您将来会发现它有帮助：

在你的模型中，或者如果你更喜欢使用控制器，那么它很好：

/**
 * Get download link from Box.com
 *
 * @param $id
 * @return bool|int|string
 */
public static function getDownloadLink($id)
{
    $client = new Client('https://api.box.com/{version}/files/{file_id}', [
        'version' => '2.0',
        'file_id' => $id,
        'request.options' => [
            'headers' => [
                'Authorization' => 'Bearer ' . self::getAccessToken(),
            ]
        ]
    ]);
    $request = $client->get('content');
    try {
        $response = $request->send();
        $result = $response->getEffectiveUrl();
    } catch (BadResponseException $e) {
        $result = $e->getResponse()->getStatusCode();
        if ($result === 401) {
            self::regenerateAccessToken();
            return self::getDownloadLink($id);
        }
    }
    return count($result) ? $result : false;
}

在上面的静态方法中，我向Box.com API发送了一个GET请求，API返回effectiveUrl，这是我们正在寻找的直接下载文件链接。
