python/flask 联系表未向 zoho 帐户发送电子邮件

问题描述

我非常需要你的帮助，我已经尝试解决这个问题一个星期了，但没有成功。

这是我的烧瓶/python 应用程序[![在此处输入图像描述][1]][1]

@app.route('/',methods=["GET","POST"])
@app.route('/home',"POST"])
def home():
    return render_template("landing.html")

def contact():
    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,subject,message):
    email_message = f"Subject: {subject}\n\nName: {name}\nEmail: {email}\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)

这是联系表单的landing.html部分：

<div class="col-lg-6">
            <form name="sentMessage" id="contactForm" action="{{ url_for('home') }}" method="post" novalidate>
              <div class="control-group">
                <div class="form-group floating-label-form-group controls">
                  <label>Name</label>
                  <input type="text" name="name" class="form-control" placeholder="Name" id="name" required data-validation-required-message="Please enter your name.">
                  <p class="help-block text-danger"></p>
                </div>
              </div>
              <div class="control-group">
                <div class="form-group floating-label-form-group controls">
                  <label>Email Address</label>
                  <input type="email" name="email" class="form-control" placeholder="Email Address" id="email" required data-validation-required-message="Please enter your email address.">
                  <p class="help-block text-danger"></p>
                </div>
              </div>
              <div class="control-group">
                <div class="form-group col-xs-12 floating-label-form-group controls">
                  <label>Subject</label>
                  <input type="text" name="subject" class="form-control" placeholder="Subject" id="subject" required data-validation-required-message="Please enter the subject.">
                  <p class="help-block text-danger"></p>
                </div>
              </div>
              <div class="control-group">
                <div class="form-group floating-label-form-group controls">
                  <label>Message</label>
                  <textarea rows="5" name="message" class="form-control" placeholder="Message" id="message" required data-validation-required-message="Please enter a message."></textarea>
                  <p class="help-block text-danger"></p>
                </div>
              </div>
              <br>
              <div id="success"></div>
              <button type="submit" class="btn btn-primary" id="sendMessageButton">Send</button>
            </form>

我有 2 个不同的错误，具体取决于我是从移动设备还是从 Mac 发送，如果我从移动设备发送，应用程序日志显示 status=200，如果从 Mac 发送，则显示 status=404

我对 Flask/python 还很陌生，我被困在这个问题上，有人可以帮我吗？谢谢！

解决方法

由于您收到电子邮件状态代码，因此您的 Flask 代码非常接近工作状态。问题可能只是一两个配置更改。

以下是一些调试建议：

如果 Flask/Python 的电子邮件代码中有调试选项，请打开它，看看是否能获得有关失败的更详细信息。
在 Stackoverflow 中搜索 [zoho][smtp] 并通读问题。这是一个常见的问题。问题将出现在不同的编码语言中，但它们大多都通过 Zoho 的 smtp 服务器发送电子邮件。
尝试通过 python 发送一封电子邮件，中间没有烧瓶，只是为了降低复杂性，看看你是否可以从那里解决问题。此 Stackoverflow 链接讨论了一些 Python 邮件选项：Sending HTML email using Python
