我目前正在尝试创建一个联系我们的表单，用户可以在其中向我的个人电子邮件地址发送任何类型的报告。为了这个例子，我们称它为my-email-address@email.com。
目前我不太关心用户的电子邮件。假设我将使用以下信息。
from:"my-email-address@email.com"to:"my-email-address@email.com"subject:"a subject name"
第 1 步：我views/home/contact_us.html.erb使用 AJAX POST 请求创建了我的表单：
<form id="sendEmailForm">
<div class="form-group mb-3">
<input type="email" class="form-control" id="exampleFormControlInput1" placeholder="Enter your email">
</div>
<div class="form-group mb-3">
<input type="text" class="form-control" id="exampleFormControlInput2" placeholder="Enter a subject (Optional)">
</div>
<div class="form-group mb-3">
<textarea class="form-control" placeholder="Please write your name, company-name, and what you would like to achieve." id="exampleFormControlTextarea3" rows="5"></textarea>
</div>
<button type="submit" class="btn btn-primary mb-2">Send Email</button>
</form>
<script type="text/javascript">
$('#sendEmailForm').on('submit', function(e) {
e.preventDefault();
e.stopPropagation();
let final_json_data = {
email: document.getElementById("exampleFormControlInput1").value,
subject: document.getElementById("exampleFormControlInput2").value,
content: document.getElementById("exampleFormControlTextarea3").value
};
jQuery.ajax({
url: '/home/send_email_to_server',
type: "POST",
data: {emailDetails: final_json_data},
success: function(result) {
alert("ajax request OK!");
},
fail: function(result) {
alert("ajax has failed")
}
});
});
</script>
第 2步：我的家庭控制器和 routes.rb：
class HomeController < ApplicationController
def contact_us
puts "GETTING THE PAGE !!!!!!!!!!!!!!!!!!!"
end
def send_email_to_server
@emailDetails = params[:emailDetails]
puts ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
puts " Store email details on server"
puts @emailDetails['email']
puts @emailDetails['subject']
puts @emailDetails['content']
puts ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
ContactUsMailer.notify_server_via_email(@emailDetails['email'], @emailDetails['subject']).deliver
puts ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
end
end
Rails.application.routes.draw do
get 'home/contact_us'
post 'home/send_email_to_server'
end
第 3 步：修改application_mailer.rb为具有默认值from-email：
class ApplicationMailer < ActionMailer::Base
default from: "my-email-address@email.com"
layout 'mailer'
end
第 4 步：修改contact_us_mailer.rb为使用捕获的参数处理请求：
class ContactUsMailer < ApplicationMailer
def notify_server_via_email(toEmail, aSubject)
puts ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
puts " Trying to send an email . . . "
@email = toEmail
@subject = aSubject
puts @email
puts @subject
puts ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
mail(
to: @email,
subject: @subject
)
end
end
第 4 步：然后在views/contact_us_mailer我创建了一个名为的新文件notify_server_via_email.html.erb并添加了以下内容：
<h1> hello world </h1>
所以这是按顺序发生的：
- 用户填写表单并提交按钮。
- AJAX 发布请求到
/home/send_email_to_server - 服务器接收请求并捕获参数并执行
mail()函数
但是我收到以下错误：

Completed 500 Internal Server Error in 30095ms (ActiveRecord: 0.0ms | Allocations: 11373)
EOFError (end of file reached):
app/controllers/home_controller.rb:35:in `send_email_to_server'
我不知道是什么导致了 500 内部服务器错误。我目前正在开发方面工作，我知道我不应该这样做，但这只是为了测试目的，我的目标不是永远保留这个配置。另外，我遇到了与我的问题类似的StackOverflow 问题，但没有明确的答案，因为那是大学 wifi 阻止 smtp 请求工作。我正在尝试使用家庭 wifi。
另外，这里还有我的development.rb命令供参考action_mailer：
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => 'localhost',
:port => 3000
}
config.action_mailer.default_url_options = {host: 'localhost:3000'}
config.action_mailer.perform_caching = false
