javascript - Sendgrid 入站 webhook 与 Node 和 multer

Question

我正在尝试使用 node、express 和 multer 通过入站 webhook 存储来自 sendgrid 的电子邮件。 sendgrids 网站上有一个例子如下:

var express = require('express');
var multer  = require('multer');
var upload = multer();
var app = express();

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.use(multer());
});
app.post('/parse', upload.array('files', 3) function (req, res) {
  var from = req.body.from;
  var text = req.body.text;
  var subject = req.body.subject;
  var num_attachments = req.body.attachments;
  for (i = 1; i <= num_attachments; i++){
    var attachment = req.files['attachment' + i];
    // attachment will be a File object
  }
});

var server = app.listen(app.get('port'), function() {
  console.log('Listening on port %d', server.address().port);
});

发送带有附件的电子邮件时，此代码会引发错误。错误是“意外的领域”。我假设 array.upload("files",3) 的声明是问题所在。有人解决了吗？

Answer 1

当您没有字段名称时，您可以使用 .any() 来解决这个问题(参见 documentation for any()

示例代码

app.post('/parse', upload.any() function (req, res) {
  var from = req.body.from;
  var text = req.body.text;
  var subject = req.body.subject;
  var num_attachments = req.body.attachments;
  for (i = 1; i <= num_attachments; i++){
    var attachment = req.files['attachment' + i];
    // attachment will be a File object
  }
});
