<b>AI摘要</b>
<p id="ai-output">这篇文章讨论了在Windows环境下，让Python脚本接收OAuth2.0授权码Code的几种方法。作者尝试了以下几种方式：
1. **URI Scheme**: 通过注册伪协议（如mayx://）并在Python脚本中解析回调URL来获取Code，但这种方法可能被杀毒软件阻拦，且不是所有平台都支持。
2. **HTTP服务监听**: 使用Flask创建一个简单的web服务来接收Code，虽然简单但可能占用过多资源，且已被弃用。
3. **Socket实现**: 用socket进行TCP连接来处理请求，但初次访问时有问题，且代码复杂。
4. **http.server模块**: 使用Python内置的HTTP服务器模块实现了基本功能，更小且稳定，但仍有程序结束前端口未释放的问题，后来通过AI得到了解决。
作者在寻找最合适的方案时遇到困难，感慨了解更多信息有时也带来困扰，但最终还是AI有效地解决了问题。</p>

<p>最近我在写一个在Windows上运行的Python脚本，需要做一个类似于第三方登录的功能。一般来说像这种东西都是使用的OAuth2.0来做认证，我接入的平台没有悬念的也是使用的这个东西，其中的重点就是获取到第三方网站的授权码Code，然后用它换取用户信息。于是我就在想怎么做比较好呢？</p>

</h2>
<p>我看VSCode在实现类似功能的时候似乎用到了URI Scheme，就是在系统中注册一个伪协议，然后通过这个伪协议来调用程序实现获取Code，方法很简单，首先先在注册表里导入：</p>
<div class="language-ini highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="err">Windows</span> <span class="err">Registry</span> <span class="err">Editor</span> <span class="err">Version</span> <span class="err">5.00</span>
<span class="nn">[HKEY_CLASSES_ROOT\mayx]</span>
<span class="err">"URL</span> <span class="err">Protocol"="D:\\mayx.exe"</span>
<span class="err">@="MayxProtocol"</span>
<span class="nn">[HKEY_CLASSES_ROOT\mayx\DefaultIcon]</span>
<span class="err">@="D:\\mayx.exe,1"</span>
<span class="nn">[HKEY_CLASSES_ROOT\mayx\shell]</span>
<span class="nn">[HKEY_CLASSES_ROOT\mayx\shell\open]</span>
<span class="nn">[HKEY_CLASSES_ROOT\mayx\shell\open\command]</span>
<span class="err">@="\"D:\\mayx.exe\"</span> <span class="err">\"%1\""</span>
</code></pre></div></div>
<p>然后编写一个Python脚本并用Pyinstaller打包：</p>
<div class="language-python highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="kn">import</span> <span class="nn">sys</span>
<span class="k">print</span><span class="p">(</span><span class="n">sys</span><span class="p">.</span><span class="n">argv</span><span class="p">[</span><span class="mi">1</span><span class="p">])</span>
</code></pre></div></div>
<p>最后将回调地址填为“mayx://get”，这样认证完成之后就会像这样调用程序：“D:\mayx.exe mayx://get?code=something”，再用urllib简单做个解析就完成了。 </p><p>
这样看起来是不是非常的简单？看起来确实是挺简单的，可惜坑比较大，第一个是像上述这样的注册表有些杀毒软件会拒绝导入，因为像“shell\open\command”这种东西被病毒啥的滥用的地方太多了，除非软件通过了数字签名或者某些认证，否则正常情况下根本没法导入。二是不是所有的第三方平台都支持伪协议的方式调用，不过我试了一下我用的那个平台倒是支持😂，除了杀毒软件比较讨厌之外其他的倒还好。</p>

<p>很多跨平台的程序，像有些主要在Linux上运行的某些程序就喜欢在获取Code的时候启动一个简单的web服务。其实用这个方法的话可能还更方便一点，不容易出问题。</p>

</h3>
<p>最开始，我想着要不然就用Flask来实现这个功能吧，实现起来也简单，写起来就几行：</p>
<div class="language-python highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="kn">from</span> <span class="nn">flask</span> <span class="kn">import</span> <span class="n">Flask</span><span class="p">,</span> <span class="n">request</span>

<p>看起来也确实很简单，功能实现的也很完美，但是有个问题是总感觉用Flask做这么简单的事情实在是大材小用，打包成程序也要占不少空间，另外就是这个方法已经被弃用了，感觉就是很不爽。那要说不爽的话怎么才爽呢？</p>

<p>最后打包试了一下，功能正常，虽然还是大了点，不过比Flask小😁。其实我在写这个代码的时候，最开始不知道要在最后加上<code class="language-plaintext highlighter-rouge">server.socket.close()</code>，一开始写的时候总是遇到程序执行完之前端口必定不会释放，令人很烦，直接搜也没什么好的结果，不过问了下ChatGPT立马就解决了🤣，它说：</p>
<blockquote>
<p>当你调用<code class="language-plaintext highlighter-rouge">server.shutdown()</code>来停止服务器时，它会停止接收新的连接，并关闭已有的连接。但是，由于Python的socket库的设计，socket对象并不会立即释放端口。相反，它会在一段时间内处于TIME_WAIT状态，以确保在网络中所有挂起的数据都被正确传递或丢弃。这是一种网络协议的要求，称为”TCP TIME_WAIT”状态。</p>

<p>AI还真是方便啊……</p>

<p>解决这么一个小问题却一时半会拿不下最合适的方案，这难道就是了解太多的副作用吗😝，不过最终来看还是AI厉害，一下子就解决了我的问题。</p></main>
