node.js - NGINX 反向代理部署后 ExpressJS 文件上传停止

Question

我在我的 ExpressJS 应用程序上使用 Multer 进行文件上传，在我使用 nginx 作为反向代理部署该应用程序之前，所有上传工作都正常进行。我似乎无法弄清楚出了什么问题。我还使用 Vimeo 库进行 Vimeo 上传，该库也已停止。

Everything below still works perfectly on my local system and wasworking perfectly online until I started using adomain on NGINX instead of a NodeJS IP:PORT

I have also installed Lets Encrypt SSL during the same process, I'mnot sure if that will cause trouble here.

以下是我使用 Vimeo API 将图像上传到文件系统和将视频上传到 Vimeo 服务器的代码。

var multer  = require('multer')
var upload = multer({ dest:'public/uploads/' })
var Vimeo = require('vimeo').Vimeo;
var lib = new Vimeo('somekey', 'someuser', 'somepass');


/* HANDLE IMAGE POST */
router.post('/profile', upload.single('picture'), function(req, res) {
  if(req.file){
    req.body.picture = req.file.filename;
  }
});


/* HANDLE VIDEO POST */
router.post('/video-vimeo', upload.single('vimeovideo'), function(req, res) {
  if(req.file){
    req.body.videourl = req.file.filename;
  }
  var vimeoUrl ='/public/uploads/'+req.file.filename;
  lib.streamingUpload(vimeoUrl,  function (error, body, status_code, headers) {
      if (error) { throw error; }
      lib.request(headers.location, function (error, body, status_code, headers) {
          var video = {};
          video._id = req.body._id;
          video.videourl = body.link;
          videoModel.findByIdAndUpdate(video._id, video, function(err, dish) {
            if (err) { console.log(err); }
            else{ res.redirect(req.get('referer')); }
          });
      });
  });
});

我的 nginx 设置(/etc/nginx/sites-enabled):

server {
    listen 443 ssl http2 default_server;
    listen [::]:443 ssl http2 default_server;
    include snippets/ssl-example.com.conf;
    include snippets/ssl-params.conf;

    server_name example.com www.example.com;

    location / {
        proxy_pass http://localhost:8080;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Express 中的 NodeJS 服务器 (bin/www):

var app = require('../app');
var debug = require('debug')('example:server');
var http = require('http');

var port = normalizePort(process.env.PORT || '8080');
app.set('port', port);

var server = http.createServer(app);

server.listen(port, 'localhost');
server.on('error', onError);
server.on('listening', onListening);

我发现一些文章建议在我的 NGINX 配置中添加以下内容(它对我不起作用):

location /public/uploads {
    limit_except POST          { deny all; }

    client_body_temp_path      /tmp/;
    client_body_in_file_only   on;
    client_body_buffer_size    128K;
    client_max_body_size       1000M;

    proxy_pass_request_headers on;
    proxy_set_header           X-FILE $request_body_file;
    proxy_set_body             off;
    proxy_redirect             off;
    proxy_pass                 http://localhost:8080/public/uploads;
}

请让我知道这是否是一个常见问题？我做错了什么？

我最近遇到了这个问题，花了几天时间想弄明白。

在生产模式下，上传文件夹与在开发模式下或本地主机上的位置不同。

尝试在开发和生产环境中运行一些控制台日志，以找出上传文件夹的位置。

这是我的 multer.diskStorage 代码

const storage = multer.diskStorage({
  destination(req, file, cb) {
    process.env.NODE_ENV === 'production'
      ? cb(null, '../uploads/')
      : cb(null, 'uploads/')
  },
  filename(req, file, cb) {
    cb(
      null,
      `${file.fieldname}-${Date.now()}${path.extname(file.originalname)}`
    )
  },
})
