Android改造2，选择视频并上传到服务器

问题描述 投票：0回答：1

我正在努力学习android，我现在很好，不是很好。试图扩展我的技能组合。

所以我试图通过改造将视频上传到服务器。我的改造工作上传EditText等。我在这里使用相同的IP地址。 在代码中相机工作精细录制视频并重命名视频，我相信选择视频工作正常（不完全确定，但画廊打开我选择一个视频，它不会崩溃所以......，PHP允许我使用post man发布视频。但是当我点击上传按钮崩溃时。我不确定问题是在获取真实路径，在改装代码中，还是我的文件选择不起作用？我需要一个更好的程序员可以帮我解决这个问题。我一直在寻找过多的问题。尝试了多个例子。只是没有让它发挥作用。我无法弄清楚错误。我试图在那里扔一些吐司，看看我是否得到了一个错误，但我没有得到祝酒。只是一个崩溃。这是我的代码。我至少在尝试，给我一个骨头。

你的控制器方法都错了，你必须使用Request / Response对象而不是返回修改后的Response;我的版本更接近预期用途，但它并不完美，主要是因为我没有Android工具。

我希望它有所帮助，更多信息在这里：Request UploadedFiles HttpStatusCodes

    $app->post('/saveFile', function(\Slim\Http\Request $request, \Slim\Http\Response $response){

    $responseData = [];
    $responseCode = 400;

    /** @var \Psr\Http\Message\UploadedFileInterface[] $files */
    $files    = $request->getUploadedFiles();
    /** @var string[] $postData */
    $postData = $request->getParsedBody();

    if ( !empty($postData['desc']) && ($postData['ID']) && !empty($files)) {
        $upload = new uploads();

        // use this if you are only upload one file
        // otherwise loop though them all
        $file = reset($files);

        $desc = $postData['desc'];
        $ID   = $postData['ID'];

        // this means the file was uploaded ok
        if ( $file->getError() === UPLOAD_ERR_OK ) {
            if ( $upload->saveFile($ID, $file, $file->getClientMediaType(), $desc) ) {
                $responseData['error']   = false;
                $responseData['message'] = 'File Uploaded Successfully';

                $responseCode = 200;
            }

            else {
                $responseData['error']   = true;
                $responseData['message'] = 'Required parameters are not available';

                $responseCode = 406;
            }
        }
        else {
            $responseData['error']   = true;
            $responseData['message'] = 'File upload error: '. $file->getError();

            $responseCode = 409;
        }
    }

    return $response->withJson($responseData, $responseCode);
});
