<div class='BlogContent'><p>SocketServer简化了网络服务器的编写。它有4个类：TCPServer，UDPServer，UnixStreamServer，UnixDatagramServer。这4个类是同步进行处理的，另外通过ForkingMixIn和ThreadingMixIn类来支持异步。</p>
<p>创建服务器的步骤。首先，你必须创建一个请求处理类，它是BaseRequestHandler的子类并重载其handle()方法。其次，你必须实例化一个服务器类，传入服务器的地址和请求处理程序类。最后，调用handle_request()(一般是调用其他事件循环或者使用select())或serve_forever()。</p>
<p>集成ThreadingMixIn类时需要处理异常关闭。daemon_threads指示服务器是否要等待线程终止，要是线程互相独立，必须要设置为True，默认是False。</p>
<p>无论用什么网络协议，服务器类有相同的外部方法和属性。</p>
<p>该模块在python3中已经更名为socketserver。</p>
<span id="OSC_h2_1"></span>
<h2>服务器类型<a href="http://automationtesting.sinaapp.com/blog/m_SocketServer#服务器类型" rel="nofollow"></a></h2>
<p>5种类型：BaseServer，TCPServer，UnixStreamServer，UDPServer，UnixDatagramServer。 注意：BaseServer不直接对外服务。</p>
<span id="OSC_h2_2"></span>
<h2>服务器对象<a href="http://automationtesting.sinaapp.com/blog/m_SocketServer#服务器对象" rel="nofollow"></a></h2>
<ul>
<li><p>class SocketServer.BaseServer：这是模块中的所有服务器对象的超类。它定义了接口，如下所述，但是大多数的方法不实现，在子类中进行细化。</p></li>
</ul>
<ul>
<li><p>BaseServer.fileno()：返回服务器监听套接字的整数文件描述符。通常用来传递给select.select(), 以允许一个进程监视多个服务器。</p></li>
</ul>
<ul>
<li><p>BaseServer.handle_request()：处理单个请求。处理顺序：get_request(), verify_request(), process_request()。如果用户提供handle()方法抛出异常，将调用服务器的handle_error()方法。如果self.timeout内没有请求收到， 将调用handle_timeout()并返回handle_request()。</p></li>
</ul>
<ul>
<li><p>BaseServer.serve_forever(poll_interval=0.5): 处理请求，直到一个明确的shutdown()请求。每poll_interval秒轮询一次shutdown。忽略self.timeout。如果你需要做周期性的任务，建议放置在其他线程。</p></li>
</ul>
<ul>
<li><p>BaseServer.shutdown()：告诉serve_forever()循环停止并等待其停止。python2.6版本。</p></li>
</ul>
<ul>
<li><p>BaseServer.address_family: 地址家族，比如socket.AF_INET和socket.AF_UNIX。</p></li>
</ul>
<ul>
<li><p>BaseServer.RequestHandlerClass：用户提供的请求处理类，这个类为每个请求创建实例。</p></li>
</ul>
<ul>
<li><p>BaseServer.server_address：服务器侦听的地址。格式根据协议家族地址的各不相同，请参阅socket模块的文档。</p></li>
</ul>
<ul>
<li><p>BaseServer.socketSocket：服务器上侦听传入的请求socket对象的服务器。</p></li>
</ul>
<p>服务器类支持下面的类变量：</p>
<ul>
<li><p>BaseServer.allow_reuse_address：服务器是否允许地址的重用。默认为false ，并且可在子类中更改。</p></li>
</ul>
<ul>
<li><p>BaseServer.request_queue_size</p></li>
</ul>
<p>请求队列的大小。如果单个请求需要很长的时间来处理，服务器忙时请求被放置到队列中，最多可以放request_queue_size个。一旦队列已满，来自客户端的请求将得到 “Connection denied”错误。默认值通常为5 ，但可以被子类覆盖。</p>
<ul>
<li><p>BaseServer.socket_type：服务器使用的套接字类型; socket.SOCK_STREAM和socket.SOCK_DGRAM等。</p></li>
</ul>
<ul>
<li><p>BaseServer.timeout：超时时间，以秒为单位，或 None表示没有超时。如果handle_request()在timeout内没有收到请求，将调用handle_timeout()。</p></li>
</ul>
<p>下面方法可以被子类重载，它们对服务器对象的外部用户没有影响。</p>
<ul>
<li><p>BaseServer.finish_request()：实际处理RequestHandlerClass发起的请求并调用其handle()方法。 常用。</p></li>
</ul>
<ul>
<li><p>BaseServer.get_request()：接受socket请求，并返回二元组包含要用于与客户端通信的新socket对象，以及客户端的地址。</p></li>
</ul>
<ul>
<li><p>BaseServer.handle_error(request, client_address)：如果RequestHandlerClass的handle()方法抛出异常时调用。默认操作是打印traceback到标准输出，并继续处理其他请求。</p></li>
</ul>
<ul>
<li><p>BaseServer.handle_timeout()：超时处理。默认对于forking服务器是收集退出的子进程状态，threading服务器则什么都不做。</p></li>
</ul>
<ul>
<li><p>BaseServer.process_request(request, client_address) :调用finish_request()创建RequestHandlerClass的实例。如果需要，此功能可以创建新的进程或线程来处理请求,ForkingMixIn和ThreadingMixIn类做到这点。常用。</p></li>
</ul>
<ul>
<li><p>BaseServer.server_activate()：通过服务器的构造函数来激活服务器。默认的行为只是监听服务器套接字。可重载。</p></li>
</ul>
<ul>
<li><p>BaseServer.server_bind()：通过服务器的构造函数中调用绑定socket到所需的地址。可重载。</p></li>
</ul>
<ul>
<li><p>BaseServer.verify_request(request, client_address)：返回一个布尔值，如果该值为True ，则该请求将被处理，反之请求将被拒绝。此功能可以重写来实现对服务器的访问控制。默认的实现始终返回True。client_address可以限定客户端，比如只处理指定ip区间的请求。 常用。</p></li>
</ul>
<span id="OSC_h2_3"></span>
<h2>请求处理器<a href="http://automationtesting.sinaapp.com/blog/m_SocketServer#请求处理器" rel="nofollow"></a></h2>
<p>处理器接收数据并决定如何操作。它负责在socket层之上实现协议（i.e., HTTP, XML-RPC, or AMQP)，读取数据，处理并写反应。可以重载的方法如下：</p>
<ul>
<li><p>setup(): 准备请求处理. 默认什么都不做，StreamRequestHandler中会创建文件类似的对象以读写socket.</p></li>
<li><p>handle(): 处理请求。解析传入的请求，处理数据，并发送响应。默认什么都不做。常用变量：self.request，self.client_address，self.server。</p></li>
<li><p>finish(): 环境清理。默认什么都不做，如果setup产生异常，不会执行finish。</p></li>
</ul>
<p>通常只需要重载handle。self.request的类型和数据报或流的服务不同。对于流服务，self.request是socket 对象；对于数据报服务，self.request是字符串和socket 。可以在子类StreamRequestHandler或DatagramRequestHandler中重载，重写setup()和finish() ，并提供self.rfile和self.wfile属性。 self.rfile和self.wfile可以读取或写入，以获得请求数据或将数据返回到客户端。</p>
