\n\nvar express = require(\'express\');\nvar multer = require(\'multer\');\n\n// Create server\nvar app = express();\n\n// Start server\nfunction startServer() {\n var port = 8888;\n server = app.listen(port, function () {\n console.log(\'Node version:\' + process.versions.node);\n console.log(\'Express server listening on port %d in %s mode\', port, app.settings.env);\n });\n}\n\nvar upload = multer({dest: \'./tmp/\'});\n\nvar app = express()\n\napp.post(\'/\', upload.single(\'data\'), function (req, res, next) {\n console.log(req.file);\n});\n\nstartServer();\n这是测试上传的 html 页面：
