如何解析用maildir保存的郵件？

我正試圖使用郵件解析郵件。郵件保存在Maildir。結果我得到錯誤的數據。如何解析用maildir保存的郵件？

散列中與電子郵件標題匹配的元素爲空，郵件正文被解析爲郵件的原始數據。

它的結果：

{:multipart=>false, 
:parts_length=>0, 
:from_addresses=>"", 
:sender=>nil, 
:to=>[], 
:cc=>[], 
:subject=>nil, 
:date=>"",

我用郵件，Maildir的和Maildir隊列

控制器：

def index 
    read_mails_from_server(params[:account_id]) 
    @new_messages=[] 
    @queue.list(:new).each do |message| 
     new_message ={} 
     mail = Mail.new(message.data) 
     new_message[:multipart] = mail.multipart? 
     new_message[:parts_length] = mail.parts.length 
     new_message[:from_addresses] = mail.from.to_s 
     new_message[:sender] = mail.sender 
     new_message[:to] = mail.to_addrs 
     new_message[:cc] = mail.cc_addrs 
     new_message[:subject] = mail.subject 
     new_message[:date] = mail.date.to_s 
     new_message[:message_id] = mail.message_id 
     new_message[:body] = mail.body 
     @new_messages << new_message 

    end 
    end 

    def read_mails_from_server(account_id) 
    @account = Account.where(:id => account_id.to_s).last 
    #TODO: check existence of directory and pass it if true 
    @mail = Mail::POP3.new :address => @account.incoming_server.address.to_s, 
          :port => @account.incoming_server.port.to_i, 
          :user_name => @account.username.to_s, 
          :password => @account.password.to_s, 
          :authentication => @account.incoming_server.authentication.to_sym, 
          :enable_ssl => (@account.incoming_server.ssl_led.to_s == "1" ? true : false) 

    @queue = Maildir::Queue.new("./mails/#{@account.username.to_s}/maildir") 

    @mail.all.each { |mail| @queue.push(mail) } 
    end

查看：

<table class="standart" style="font-size: smaller;"> 
    <tr> 
    <th>Multipart:</th> 
    <th>Parts</th> 
    <th>From</th> 
    <th>From addresses</th> 
    <th>Sender</th> 
    <th>To</th> 
    <th>CC</th> 
    <th>Subject</th> 
    <th>Date</th> 
    <th>Message ID</th> 
    <th>Body</th> 
    </tr> 
    <% @new_messages.each do |message| %> 
     <tr> 
     <td><%= message[:multipart] %></td> 
     <td><%= message[:parts_length] %></td> 
     <td><%= message[:from] %></td> 
     <td><%= message[:from_addresses] %></td> 
     <td><%= message[:sender] %></td> 
     <td><%= message[:to].each{|address| address.to_s + ", "} %></td> 
     <td><%= message[:cc] %></td> 
     <td><%= message[:subject] %></td> 
     <td><%= message[:date] %></td> 
     <td><%= message[:message_id] %></td> 
     <td><%= message[:body] %></td> 
     <td><%= message[:body_1] %></td> 
     </tr> 
    <% end %> 
</table>

我發現，該郵件接收數據corr實際上，在保存到Maildir之前必須解析數據。但Maildir在保存時正在破壞數據結構。

有人可以幫我解決這個問題嗎？

我發現mailman（https://github.com/titanous/mailman）在嘗試處理傳入的電子郵件時相當不錯。 –

我找到了我的問題的解決方案。

我在兩種方法中分開了操作：index和read_mails_from_server，我只在保存郵件之前定義了Maildir的序列化程序，但是在讀取消息之前沒有定義它。

此代碼的工作好：

def index 
    read_mails_from_server(params[:account_id]) 
    @new_messages=[] 
    @queue.serializer = Maildir::Serializer::Mail.new 
    @queue.list(:new).each do |message| 
     new_message ={} 
     mail = Mail.read_from_string(message.data) 
     new_message[:from_addresses] = mail.from.to_s 
     new_message[:sender] = mail.sender 
     new_message[:to] = mail.to_addrs 
     new_message[:cc] = mail.cc_addrs 
     new_message[:subject] = mail.subject 
     new_message[:date] = mail.date.to_s 
     new_message[:message_id] = mail.message_id 
     new_message[:body] = mail.body.encoded 
     new_message[:body_1] = message.data 
     @new_messages << new_message 

    end 
    end

我不明白，爲什麼我必須在每一個方法，在使用單@queue對象定義序列化？
