我正在尝试使用Guzzle3和Ajax从Dropbox下载文件.当我使用Guzzle发送发帖请求时,我在控制台上收到以下原始代码：

这是我正在使用的Guzzle3代码：

$client = new Client();
        $request = $client->post('https://content.dropboxapi.com/2/files/download');
        $request->setHeaders([
            'Authorization' => 'Bearer ' . self::getAccessToken(),
            'Dropbox-API-Arg' => '{"path": "/Box/' . $dropboxPath . '/' . $fileName . '"}'
        ]);

        try {
            $response = $request->send();

            return $response;
        } catch (BadResponseException $e) {

            return $e->getResponse();
        }

这是我正在使用的Ajax代码：

$.ajax({
    type: 'POST',
    url: '/downloaddropbox/' + filePath + '/' + fileName,
    data: 'filePath=' + filePath + '&fileName=' + fileName,
    beforeSend: function () {
        Materialize.toast('Please, wait while we\'re processing your download request.', 4000);
        $('.progress').show();
            },
    complete: function () {
        $('.progress').hide();
    },
    success: function (data) {
        console.log(data);
            },
    error: function () {
        Materialize.toast('Something goes wrong. Please, try again later!', 4000);
    }
});

任何人都可以帮助我如何从Ajax请求中下载文件.我也尝试过使用base64_encode结果,但是它仍然不起作用,因为我不仅会下载图像文件.

解决方法:

我建议改用dropbox API.

如文档的下载部分所示,在身份验证之后,您可以使用以下方式读取(下载)文件：

$localFile = fopen("working-draft.txt", "w+b");
$fileMetadata = $dbxClient->getFile("/file-in-dropbox.txt", $localFile);
fclose($localFile);
print_r($fileMetadata);

附言
如注释下面的建议,使用API​​或任何其他方法,您必须适当设置标头(根据您要下载的文件类型)
