Express JS路由器中间件- Body Parser - req.正文有连字符

Express JS Router Middleware - Body Parser - req.body has hyphen

本文关键字：req 正文 连字符 Parser Body JS 路由器 中间件 Express      更新时间：2023-09-26

我正在接收来自Mailgun的解析电子邮件，这些电子邮件通过他们的API发布到我设置的URL端点。接收HTTP帖子的URL是使用body解析器中间件的Expressjs到MongoDB的路由。我有http post的路由工作良好的MongoDB简单的文本键，如"发件人"，但我有一些包含连字符的消息参数的格式的问题。例如"body-plain"。如果包含"req.body.body-plain"的a参数，Express将抛出错误。有人有办法吗?

我不希望对整个字符串进行正则化。

下面是一个邮件回复的例子:

recipient: 'postmaster@appmail.sisdaf.com',
  sender: 'kevsdaf@mail.com',
  subject: 'tewsgs',
  from: 'Kevin Psdit <kesdfit@gmail.com>',
  'X-Envelope-From': '<kasdftit@gmail.com>',
'body-plain': 'this is a test'r'n',
  Received: 
   [ 'from mail-qk0-f179.google.com (mail-qk0-f179.google.com         [209.85.220.179]) by mxa.mailgun.org with ESMTP id 556bfda1.7f7658358ef0-    in01; Mon, 01 Jun 2015 06:37:21 -0000 (UTC)',

这是快车路线:

'use strict';
var mongoose = require( 'mongoose' );
 var Email = mongoose.model('Email');
module.exports = function(router) {
router.route('/emails')
  //creates a new email
  .post(function(req, res){
      var email = new Email();
//THESE WORK
  email.recipient = req.body.recipient;
  email.sender = req.body.sender;
  email.from = req.body.from;
  email.subject = req.body.subject;
  email.timestamp = req.body.timestamp;
  email.token = req.body.token;
  email.signature = req.body.signature;
//THESE DO NOT WORK BECAUSE OF HYPHEN IN NAME
  email.body_plain = req.body.body-plain;
  email.stripped_text = req.body.stripped-text;
  email.stripped_signature = req.body.stripped-signature;
  email.body_html = req.body.body-html;
  email.stripped_html = req.body.stripped-html;
  email.attachment_count = req.body.attachment-count;
  email.attachment_x = req.body.attachment-x;
  email.message_headers = req.body.message-headers;
  email.content_id_map = req.body.content-id-map;      
email.save(function(err, email) {
  if (err){
    return res.send(500, err);
  }
  return res.json(email);
});
  })

解决方法是使用括号表示法，这样就可以访问包含点表示法无效字符的键

req.body['body-plain']

Extra Details:如果您使用的是mongoose模型，并且它也有连字符，那么您可以这样做。

假设您的猫鼬模型是这样的，请注意名称中带有连字符的属性: 

const augmentedWritingTextSchema = new mongoose.Schema({
  text: {
    type: String,
    required: true,
    unique: false,
  },
  name: {
    type: String,
    required: true,
  },
  'profile-id': {
    type: String,
    required: true,
  },
  'profile-type': {
    type: String,
    required: true,
  },
  'company-wide-visibility': {
    type: String,
    required: true,
  },
});
当使用mongoose模型时，你的文档应该是这样的: 
  augmentedWritingTextDocument = new AugmentedWritingText({
      text: reqObj.text,
      name: reqObj.name,
      'profile-id': reqObj['profile-id'],
      'profile-type': reqObj['profile-type'],
      'company-wide-visibility': reqObj['company-wide-visibility'],
    });
