从C/C ++解析简单的MIME文件? [英] Parsing simple MIME files from C/C++?

问题描述

我已经在网上搜索了几天，但似乎找不到解决我问题的好方法:

I have searched the web for days now but I can't seem to find a good solution to my problem:

对于我的一个项目，我正在寻找一个好的(轻量级)MIME解析器.我的客户提供了MIME格式的文件(线性，无层次结构)，其中包含3-4个部分".该应用程序必须能够拆分这些部分并独立处理它们.

For one of my projects I'm looking for a good (lightweight) MIME parser. My customer provides MIME formatted files (linear, no hierarchy) which contain 3-4 "parts". The application must be able to split those parts and process them independently.

基本上，这些MIME文件就像原始的电子邮件一样，但是没有SMTP标头.取而代之的是，它们以MIME标题"MIME版本:1.0"开头，然后是各部分.

Basically those MIME files are like raw E-Mail messages, but without the SMTP-headers. Instead they begin with the MIME-Header "MIME-Version: 1.0" and after that the parts follow.

我正在为应用程序使用C ++，因此欢迎使用C ++库.也欢迎使用标准C库.但应符合以下条件:

I am using C++ for the application, so a C++ library is welcome. A standard C library is welcome, too; but it should fit the following criteria:

• 开放(至少是LGPL)，而不是财产
• 紧凑-我只需要解析器，不支持SMTP/POP3
• 跨平台(定位于Windows，Mac OS X和Linux)

经过几天的搜索，我发现了以下库以及为何不使用它们的原因:

After days of searching I found the following libs and reasons why to not use them:

• 模仿 (C ++)-尽管该库似乎完整且可用于C ++，它基于 glib ，无法在Windows上正确编译.
• Vmime (C ++)-似乎完整，但是没有Windows官方支持.他们还提供双重许可"(商业LGPL" + GPL).似乎包含在Ubuntu和Debian中，但许可令人困惑.
• mime ++ ---商业用途，不支持Mac.
• Chilkat软件MIME C ++库 --商业并专注于Windows.

• mimetic (C++) --- Although this library seems complete and for C++ usage, it is based on glib, which won't properly compile on Windows.
• Vmime (C++) --- Seems complete, but there is no official Windows support. Also they provide "dual licensing" ("commerical LGPL" + GPL). Seems to be included with Ubuntu and Debian, but the licensing is confusing.
• mime++ --- Commerical, no Mac support.
• Chilkat Software MIME C++ Library --- Commerical and focused on Windows.

我真的不想编写自己的MIME解析器. MIME如此广泛，以至于必须有一些开放库才能以理智的方式处理这种文件格式.

I don't really want to write my own MIME parser. MIME is so widespread that there must be some open library to handle this file format in a sane way.

那么，你们有什么想法，建议或链接吗?

So, do you guys have any ideas, suggestions or links?

提前谢谢！

推荐答案

已经有一段时间了.因此，我将回答我自己的问题.

It's been a while. So I'll just answer my own question.

在花了更多时间之后，我最终编写了自己的实现. MIME确实非常简单，如果您阅读文档，便可以在短时间内启动并运行它.

After spending some more time on this, I ended up writing my own implementation. MIME is quite simple indeed, and if you read the documentation, you have something up and running in a short time.

但是，我认为应该有vMime之类的东西，但是应该是开源的.我不敢相信有这么多人必须处理MIME结构，因为这是一个真正的标准.

However, I think there should be something like vMime, but open source. I can't believe that so few people have to deal with MIME structures as it's a real standard.
