Question

我正在使用PHP从AWS S3获取我的对象，然后转身并将其上传到Dropbox。我可以从AWS成功获取对象，但是当我尝试将文件上传到Dropbox时，我只是一个空的Json响应，没有任何错误或任何错误。我知道我的$ dbToken（Dropbox令牌）工作正常，因为我可以使用相同的密钥来获取我的文件夹结构和列表文件。

当我尝试上传文件时，它只是空白。我认为这与AWS预签名URL有关。我是否需要发出Curl请求才能获取该URL的内容（在我的情况下为$ secureUrl）。不知道如何写这个以及如何将此文件放入Dropbox。谢谢你的帮助。

        # ============================================
        # Connect to AWS and get the Object
        # This works fine...
        # ============================================
        $s3 = new S3Client([
            'credentials'=>[
                'key'=>xxxxxxx,
                'secret'=>xxxxxxx,
            ],
            'region'=>'us-west-2',
            'version'=>'2006-03-01',
        ]);
        $cmd = $s3->getCommand('GetObject', [
            'Bucket' => xxxxxxx,
            'Key'    => xxxxxxx,
        ]);
        $request = $s3->createPresignedRequest($cmd, '+60 seconds');
        $secureUrl = (string) $request->getUri(); // get signed uri...
        # echo $secureUrl; // if I echo this on the page, I can see the url, copy it and paste it into the browser and all works well...

        # ============================================
        # Connect To DropBox and Upload File...
        # This is returning nothing in my output...
        # ============================================
        $dbToken = 'xxxxxxx';
        $headers = [
            "Authorization: Bearer ". $dbToken,
            'Dropbox-API-Arg: {"path": "'.$secureUrl.'", "mode": "add", "autorename": true, "mute":false }',
            "Content-Type: application/octet-stream"
        ];
        $url = 'https://content.dropboxapi.com/2/files/upload';
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_POST, true);
        $path = $secureUrl;
        $fp = fopen($path, 'rb');
        curl_setopt($ch, CURLOPT_INFILE, $fp);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_VERBOSE, 1);
        $result = curl_exec($ch);
        $data = json_decode(trim($result), TRUE);
        echo '<pre>';
        print_r($data); // the json response is empty...
        echo '</pre>';
