随着闷热，它真的很简单。将multer作为中间件传递给路由器。
例如，如果要将文件上载到端点/上载文件
app.post('/uploadfile', multer_middleware, function(req, res){
res.end("uploaded");
});
multer_middleware会是这样的。
var multer_middleare = multer({ dest: './path_to_storage',
onFileUploadComplete: function (file) {
// after file is uploaded, upload it to remote server
var filename = file.name;
request({
method: 'PUT',
preambleCRLF: true,
postambleCRLF: true,
uri: 'http://remote-server.com/upload',
auth: {
'user': 'username',
'pass': 'password',
'sendImmediately': false
},
multipart: [
{ body: fs.createReadStream('./path_to_storage/' + filename) }
]
},
function (error, response, body) {
if (error) {
return console.error('upload failed:', error);
}
console.log('Upload successful! Server responded with:', body);
})
});
上传文件后，您可以使用request之类的HTTP客户端将其上传到远程服务器。
不要忘记在文件开头导入multer
var multer = require('multer');
