Python/Flask HTML表单发送电子邮件

Question

我对编程很陌生，尤其是Python/Flask。我试图有一个HTML表单提交到指定的电子邮件地址。这两天我什么都试过了，但是都没有成功。当我部署到heroku时，一切都很好，但是表单不起作用。

这是我的脚本。py

from flask import Flask, render_template, request, flash
from form import ContactForm
from flask_mail import Mail, Message
import smtplib
from dotenv import load_dotenv   #for python-dotenv method
load_dotenv()
import os
OWN_EMAIL = os.environ.get("OWN_EMAIL")
OWN_PASSWORD = os.environ.get("OWN_PASSWORD")
print(os.environ.get("OWN_EMAIL"))
print(os.environ.get("OWN_PASSWORD"))
app = Flask(__name__)
@app.route('/')
@app.route('/home', methods=["GET", "POST"])
def home():
if request.method == "POST":
data = request.form
data = request.form
send_email(data["name"], data["email"], data["subject"], data["message"])
return render_template("landing.html", msg_sent=True)
return render_template("landing.html", msg_sent=False)

def send_email(name, email, phone, message):
email_message = f"Subject:New MessagennName: {name}nEmail: {email}nSubject: {subject}nMessage:{message}"
with smtplib.SMTP("smtp.zoho.eu") as connection:
connection.starttls()
connection.login(OWN_EMAIL, OWN_PASSWORD)
connection.sendmail(OWN_EMAIL, OWN_EMAIL, email_message)
if __name__=="__main__":
app.run(debug=True)

这是我的landing。html

<div class="col-lg-6">
<form action="{{ url_for('home') }}" name="sentMessage" method="post" class="contactForm" novalidate>
<div class="row">
<div id="sendmessage">Your message has been sent. Thank you!</div>
<div id="errormessage"></div>
<div class="col-lg-6">
<div class="form-group contact-block1">
<input type="text" name="name" class="form-control" id="name" placeholder="Your Name" data-rule="minlen:4" data-msg="Please enter at least 4 chars" />
<div class="validation"></div>
</div>
</div>
<div class="col-lg-6">
<div class="form-group">
<input type="email" class="form-control" name="email" id="email" placeholder="Your Email" data-rule="email" data-msg="Please enter a valid email" />
<div class="validation"></div>
</div>
</div>
<div class="col-lg-12">
<div class="form-group">
<input type="text" class="form-control" name="subject" id="subject" placeholder="Subject" data-rule="minlen:4" data-msg="Please enter at least 8 chars of subject" />
<div class="validation"></div>
</div>
</div>
<div class="col-lg-12">
<div class="form-group">
<textarea class="form-control" name="message" rows="8" data-rule="required" data-msg="Please write something for us" placeholder="Message"></textarea>
<div class="validation"></div>
</div>
</div>
<div class="col-lg-12">
<input type="submit" class="btn btn-defeault btn-send" value="Send message">
</div>
</div>
</form>
</div>

非常感谢您的建议。

感谢

从路由中删除第一个函数。应该是:

@app.route('/home')
def home():
if request.method == "POST":
data = request.form
data = request.form
send_email(data["name"], data["email"], data["subject"], data["message"])
return render_template("landing.html", msg_sent=True)
return render_template("landing.html", msg_sent=False)

也改变这一行:

<form action="{{ url_for('home') }}"

:

<form action="/home" 

在你的HTML文件
