我有一个用于电子邮件服务的Bootstrap表单，适用于Angular 6应用程序和Node.js。我在我的应用程序中使用Nodemailer发送电子邮件，但不幸的是它不能正常工作。当我提交表单时，我会收到以下错误：
OPTIONS https://localhost:3000/contact/send 0 ()
这是表单：
<form [formGroup]="angForm" novalidate>
<div class="message">
<h3> Write to us </h3>
</div>
<div class="form__top">
<div class="form__left">
<div class="form__group">
<input class="form__input form__input--name" type="text" formControlName="name" placeholder="name" #name>
</div>
<div *ngIf="angForm.controls['name'].invalid && (angForm.controls['name'].dirty || angForm.controls['name'].touched)" class="alert alert-danger">
<div *ngIf="angForm.controls['name'].errors.required">
Name is required.
</div>
</div>
<div class="form__group">
<input class="form__input form__input--email" type="email" formControlName="email" placeholder="email" #email>
</div>
<div *ngIf="angForm.controls['email'].invalid && (angForm.controls['message'].dirty || angForm.controls['message'].touched)"
class="alert alert-danger">
<div *ngIf="angForm.controls['message'].errors.required">
message is required.
</div>
</div>
</div>
<div class="form__right">
<div class="form__group">
<textarea class="form__input form__input--textarea" placeholder="Message" formControlName="message" #message
rows="3"></textarea>
</div>
<div *ngIf="angForm.controls['message'].invalid && (angForm.controls['message'].dirty || angForm.controls['message'].touched)"
class="alert alert-danger">
<div *ngIf="angForm.controls['message'].errors.required">
message is required.
</div>
</div>
</div>
</div>
<flash-messages></flash-messages>
<div class="form__down">
<div class="form__group">
<button (click)="sendMail(name.value, email.value, message.value)" [disabled]="angForm.pristine || angForm.invalid" class="form__input form__input--submit" name="submit" type="submit" value="SEND MESSAGE">SEND MESSAGE
</button>
</div>
</div>
</form>
这是contact.js文件（node mailer的设置和路由）
const express = require('express');
const router = express.Router();
const request = require('request');
const nodemailer = require('nodemailer');
const cors = require('cors');
router.options('/send', cors());
router.get('/send', cors(), (req, res) => {
const outputData = `
<p>You have a new contact request</p>
<h3>Contact Details</h3>
<ul>
<li>Name: ${req.body.name}</li>
<li>Email: ${req.body.email}</li>
</ul>
<h3>Message</h3>
<p>${req.body.message}</p>
`;
let transporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 465,
secure: false,
port: 25,
auth: {
user: 'email',
pass: 'pass'
},
tls: {
rejectUnauthorized: false
}
});
let HelperOptions = {
from: '"kutomba" <email',
to: 'email',
subject: 'Majeni Contact Request',
text: 'Hello',
html: outputData
};
transporter.sendMail(HelperOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log("The message was sent!");
console.log(info);
});
});
module.exports = router;
以下是服务器端 JavaScript 代码。更新
// server.js
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const path = require('path');
const app = express();
// CORS Middleware
app.use(cors());
// Port Number
const port = process.env.PORT || 3000
// Run the app by serving the static files
// in the dist directory
app.use(express.static(path.join(__dirname, '/majeni/dist/majeni')));
// Body Parser Middleware
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
//routes
const contact = require('./app/routes/contact');
app.use('/contact', contact);
// If an incoming request uses
// a protocol other than HTTPS,
// redirect that request to the
// same url but with HTTPS
const forceSSL = function () {
return function (req, res, next) {
if (req.headers['x-forwarded-proto'] !== 'https') {
return res.redirect(
['https://', req.get('Host'), req.url].join('')
);
}
next();
}
}
// Instruct the app
// to use the forceSSL
// middleware
app.use(forceSSL());
app.use(function (req, res, next) {
// Website you wish to allow to connect
res.setHeader('Access-Control-Allow-Origin', 'http://localhost:3000');
// Request methods you wish to allow
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
// Request headers you wish to allow
res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
// Set to true if you need the website to include cookies in the requests sent
// to the API (e.g. in case you use sessions)
res.setHeader('Access-Control-Allow-Credentials', true);
// Pass to next layer of middleware
if ('OPTIONS' == req.method) {
res.sendStatus(200);
} else {
next();
}
});
// For all GET requests, send back index.html
// so that PathLocationStrategy can be used
app.get('/*', function (req, res) {
res.sendFile(path.join(__dirname + '/majeni/dist/majeni/index.html'));
});
// Start Server
app.listen(port, () => {
console.log('Server started on port '+port);
});
更新
以下是服务内容
import { Injectable } from '@angular/core';
import { Headers, Http, Response } from '@angular/http';
import { Jsonp } from '@angular/http';
@Injectable({
providedIn: 'root'
})
export class ContactService {
constructor(private http: Http) { }
sendEmail(name, email, message) {
const uri = 'http://localhost:3000/contact/send';
const obj = {
name: name,
email: email,
message: message,
};
return this.http.post(uri, obj);
}
}
更新：component.ts
import { Component, OnInit } from '@angular/core';
import { ContactService } from '../../contact.service';
import { FormGroup, FormBuilder, Validators } from '@angular/forms';
import { FlashMessagesModule, FlashMessagesService } from 'angular2-flash-messages';
@Component({
selector: 'app-footer',
templateUrl: './footer.component.html',
styleUrls: ['./footer.component.scss']
})
export class FooterComponent implements OnInit {
angForm: FormGroup;
constructor(
private flashMessages: FlashMessagesService,
private fb: FormBuilder,
private contactService: ContactService) {
this.createForm();
}
createForm() {
this.angForm = this.fb.group({
name: ['', Validators.required],
email: ['', Validators.required],
message: ['', Validators.required],
});
}
sendMail(name, email, message) {
this.contactService.sendEmail(name, email, message).subscribe(success => {
this.flashMessages.show('You are data we succesfully submitted', { cssClass: 'alert-success', timeout: 3000 });
console.log(success);
}, error => {
this.flashMessages.show('Something went wrong', { cssClass: 'alert-danger', timeout: 3000 });
});
}
ngOnInit() {
}
}
我的代码缺少什么？
