发送消息时出现内部服务器错误500

分类：编程问答

如何解决发送消息时出现内部服务器错误500

我是ReactJS和Flux的新手，我正在某个项目上使我的办公室网站上的发送消息功能正常，在我添加一些验证之前，所有代码均正常工作。添加一些验证后，它将发送一个内部服务器错误，当某些字段为空时，该消息将不会发送到我的电子邮件中，但是当所有字段都不为空时，该消息将发送到我的电子邮件中。

这是我的views.jsx 

...
export default class Message extends React.Component {
  constructor(props){
    super(props);
      this.state = {
        isLoggedIn: SystemStore.isLoggedIn(),profile: ProfileStore.getProfile(),fullName: SystemStore.systemUser().fullName,site: '',email: '',phone: '',home: '',subject: '',description: '',type: '',submitting: false
    };

    this.clearForm = this.clearForm.bind(this);
    this.handleProfileChange = this.handleProfileChange.bind(this);
    this.handleSubjectChange = this.handleSubjectChange.bind(this);
    this.handleMessageChange = this.handleMessageChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
    this.handleSubmitComplete = this.handleSubmitComplete.bind(this);
    this.handleSubmitError = this.handleSubmitError.bind(this);
  }

  componentDidMount(){
    ProfileStore.addProfileChangeListener(this.handleProfileChange);
      if(!this.state.profile){
        ProfileActions.reload()
      }
    MessageStore.addSubmitMessageChangeListener(this.handleSubmitComplete);
    MessageStore.addSubmitMessageFailChangeListener(this.handleSubmitError);//unresolved
  }    

  componentWillUnmount(){
    ProfileStore.removeProfileChangeListener(this.handleProfileChange);
    MessageStore.removeSubmitMessageChangeListener(this.handleSubmitComplete);
    MessageStore.removeSubmitMessageFailChangeListener(this.handleSubmitError);
  }

  render(){
    return(
      <Layout>

    )
  }

  clearForm(){
    this.setState({ subject: '',description: '' });
    alert(T.translate('msg.mailSent'));
  }

  handleProfileChange(){
    this.setState({
      site: ProfileStore.getProfile().primarySite.name,email: ProfileStore.getProfile().emailAddresses[0].email,phone: ProfileStore.getProfile().contactNumbers[0].countryCode + ProfileStore.getProfile().contactNumbers[0].number,home: ProfileStore.getProfile().contactNumbers[1].countryCode + ProfileStore.getProfile().contactNumbers[1].number,});
    if(this.state.home === ''){
      this.setState({
        home: '-'
      });
    }
  }
    
  handleSubjectChange(evt){
    this.setState({ subject: evt.target.value },() => {
      if(this.state.subject === 'PRAYER') {
        this.setState({ type: 'REQUEST' });
      } else if(this.state.subject === 'ADDRESS') {
        this.setState({ type: 'INFORMATION' });
      } else if(this.state.subject === 'VISIT'){
        this.setState({ type: 'REQUEST' });
      }
    });
  }
    
  handleMessageChange(evt){
    this.setState({ description: evt.target.value });
  }

  handleSubmit(evt) {
    evt.preventDefault();
        
    if(this.state.subject === ''){
      alert('Error:' + T.translate('msg.subjectRequired'));
    } else if(this.state.description === ''){
      alert('Error:' + T.translate('msg.mailDescriptionRequired'));
    } else {
      alert(T.translate('msg.mailSending'));
    }

    this.handleProfileChange();
    this.handleSubjectChange(evt);
    this.handleMessageChange(evt);
    var messageInfo = {
      fullName: this.state.fullName,site: this.state.site,email: this.state.email,phone: this.state.phone,home: this.state.home,subject: this.state.subject,description: this.state.description,type: this.state.type
    };
        
    console.log(messageInfo);

    this.setState({ submitting: true },() => {
      MessageActions.sendMessage(messageInfo,(err) => {
        if(err){
          this.handleSubmitError();
        }
      });
    });
  }

  handleSubmitComplete(){
    this.setState({
      submitting: false
    });
    this.clearForm();
  }

  handleSubmitError(){
    this.setState({
      submitting: false
    });
  }
}

这是我针对助焊剂结构的action.js 

...
function _sendMessage(messageInfo,callback) {
  jQuery.ajax({
    method: 'POST',url: '/api/v1/supportTickets',contentType: 'application/json',data: JSON.stringify({
      messageInfo: messageInfo
    })
  })
  .done(function(messageInfo) {
    callback(null,messageInfo);
  })
  .fail(function(err){
    console.error('Failed to send message' + JSON.stringify(err));
    callback(err);
  });
}

var MessageActions = {
  sendMessage: function(messageInfo,callback) {
    _sendMessage(messageInfo,function(err,messageInfo) {
      if(err) { return callback(err); }
      Dispatcher.dispatch({
        actionType: MessageConstants.PERFORM_SEND_MESSAGE,messageInfo
      });
      callback(null,messageInfo)
    });
  }
};

module.exports = MessageActions;

这是我的store.js 

...
const SUBMIT_MESSAGE = 'SUBMIT_MESSAGE';
const SUBMIT_MESSAGE_FAILED = 'SUBMIT_MESSAGE_FAILED';

var MessageStore = assign({},EventEmitter.prototype,{
   
  emitSubmitMessageChange: function(){
    this.emit(SUBMIT_MESSAGE);
  },addSubmitMessageChangeListener: function(callback){
    this.on(SUBMIT_MESSAGE,callback);
  },removeSubmitMessageChangeListener: function(callback){
    this.removeListener(SUBMIT_MESSAGE,emitSubmitMessageFailChange: function(){
    this.emit(SUBMIT_MESSAGE_FAILED);
  },addSubmitMessageFailChangeListener: function(callback){
    this.on(SUBMIT_MESSAGE_FAILED,removeSubmitMessageFailChangeListener: function(callback){
        this.removeListener(SUBMIT_MESSAGE_FAILED,callback);
  }
});

Dispatcher.register(function(action) {
  switch(action.actionType){
    case MessageConstants.PERFORM_SEND_MESSAGE:
      MessageStore.emitSubmitMessageChange();
      break;

    case MessageConstants.PERFORM_SEND_MESSAGE_FAIL:
      MessageStore.emitSubmitMessageFailChange();
      break;
    default:
      //noop
    }

})
export default MessageStore;

这是我通过gmail发送消息的后端

const _ = require('lodash');
const express = require('express');
const router = express.Router();

const mail = require('nodemailer');
const routing = requirerp('/lib/routing');
const api = routing.api;
const config = require('config');
const service = config.get('hits.supportTickets.service');
const host = config.get('hits.supportTickets.host');
const user = config.get('hits.supportTickets.auth.user');
const pass = config.get('hits.supportTickets.auth.pass');

const Err = requirerp('/utils/restErrors');
const validator = requirerp('/utils/restValidation');

const transporter = mail.createTransport({ //almost resolved => should move the code to another file,or just like this?
  service: 'Gmail,host: 'smtp.gmail.com,auth: {
    user: 'no.replyxxxxx@xxxx.com',pass: 'xxxxx'
  }
});

router.post('/',routing.requireAuth,(req,res,next) => {
  var fullName = req.body.fullName;
  var site = req.body.site;
  var email = req.body.email;
  var phone = req.body.phone;
  var home = req.body.home;
  var subject = req.body.subject;
  var message = req.body.description;
  var type = req.body.type;
  var content = 'Nama : ' + fullName + '\nLokasi : ' + site + '\nContact : ' + phone + '/' + home + '\nPesan : ' + message;

  validator.validateBody(req,{ //using validator get error code 500 -> Internal Server Error
    'fullName': {
      notEmpty: true
    },'site': {
      notEmpty: true
    },'email': {
      motEmpty: true
    },'phone': {
      notEmpty: true
    },'home': {
      notEmpty: true
    },'subject': {
      notEmpty: true,in: {
        option: ['PRAYER','ADDRESS','VISIT']
      }
    },'descrption': {
      notEmpty: true
    },'type': {
      notEmpty: true
    }
  },function(err) {
    if(Err.invalidInput(next,err)) { return; }

    const mailOptions = {
      from: fullName + '<' + email + '>',to: 'xxxx@xxxx.org',replyTo: email,subject: type + ':' + subject,text: content
    };
        
    transporter.sendMail(mailOptions,(err) => {
      if(Err.unexpected(next,err)) {
        return;
      }
      res.status(201)
      .header('Location',api('supportTickets/'))
      .json(req.body.messageInfo)
      .end();
    });
  })
});
    
module.exports = router;

有人可以给我一个建议，指出我的代码出了什么问题吗？非常感谢
