android - 将视频从 Android/IOS 上传到 Node 服务器时出现服务器超时错误

Question

我正在尝试将视频从 android/IOS 客户端上传到 NodeJS 服务器。它适用于较小的视频，但当我尝试上传大于 50 MB 的视频时，它会抛出服务器超时错误。

我认为一个可能的解决方案是增加服务器超时限制，但这似乎不是一个合适的解决方案。有没有一种正确的方法可以不受任何限制地从 android 上传视频？

这是我正在使用的代码。

exports.create = function(req, res) {
    req.setTimeout(0);

    var storage = multer.diskStorage({
        destination: function (req, file, cb) {
            cb(null, config.uploads.videoUpload.dest);
        },
        filename: function (req, file, cb) {
           let extArray = file.mimetype.split("/");
           let extension = extArray[extArray.length - 1];
           cb(null, Date.now()+ '.' +extension);
        }
    });

    var upload = multer({
        storage: storage,
        limits: config.uploads.videoUpload.limits,
        fileFilter: function (req, file, cb) 
        {
            if (file.mimetype !== 'image/jpeg' && file.mimetype !== 'video/mp4')
            {
               return res.status(400).send({
                  message: 'Only video files are allowed!',
                  error: true
               });
            }
            cb(null, true);
        }
    }).single('video_file');

    if (user)
    {
        // upload function with a callback
        upload(req, res, function(uploadError) {
            if (uploadError)
            {
                return res.status(400).send({
                    message: 'Error occurred while uploading Video',
                    error: true
                });
            } 
            else
            {
                return res.status(200).send({
                    message: 'Video uploaded Successfuly!',
                    error: false
                });
            }
        });
    }
    else 
    {
        res.status(400).send({
            message: 'User is not signed in',
            error: true
        });
    }
};

这种类型的错误通常与服务器或网络配置有关，而不是与您的代码有关，因此也值得检查此配置，如果可能的话，还可以尝试在同一台服务器上使用已知有效的文件上传示例。

对于 node muler 方法，以下代码经过测试，绝对适用于 Android 和服务器之间的大型视频上传:

// POST: video upload route
// multer approach
var multer = require('multer');
app.use(multer({

    //Set dstination directory
    dest: path.resolve(__dirname, 'public', 'uploaded_videos'),

    //Rename file
    rename: function (fieldname, filename) {
        //Add the current date and time in ISO format, removing the last 'Z' character this usually
        //includes
        var dateNow = new Date();
        return filename + "_" + dateNow.toISOString().slice(0,-1)
    },

    //Log start of file upload
    onFileUploadStart: function (file) {
      console.log(file.originalname + ' is starting ...')
    },

    //Log end of file upload
    onFileUploadComplete: function (file) {
      console.log(file.originalname + ' uploaded to  ' + file.path)
      done=true;
    }

}));

router.post('/web_video_upload', function(req, res) {
    //Log the request details
    //Debug console.log(req.body);
    //Debug console.log(req.files);

    //Send a resposne
    res.send('Video Uploading');
    console.dir(req.files);
});
