著名的AFNetworking网络基础库Swift版Alamofire

   <p><a href="/misc/goto?guid=4958851213782329914" target="_blank">源代码</a> </p>    <p href="https://simg.open-open.com/show/3be6b214272b2778f4f0a758964dccea.gif"><img alt="著名的AFNetworking网络基础库Swift版Alamofire" src="https://simg.open-open.com/show/3be6b214272b2778f4f0a758964dccea.gif" width="369" height="648" /> </p>    <h2>Swift Alamofire 简介 </h2>    <p href="https://simg.open-open.com/show/aa4382121a7983d8b102b05d2c3c0fcb.png"><img alt="著名的AFNetworking网络基础库Swift版Alamofire" src="https://simg.open-open.com/show/aa4382121a7983d8b102b05d2c3c0fcb.png" width="700" height="205.88235294117646" /> </p>    <p>Alamofire是 Swift 语言的 HTTP 网络开发工具包,相当于Swift实现<a href="/misc/goto?guid=4958968172213038536">AFNetworking</a>版本。 </p>    <p>当然,AFNetworking非常稳定,在Mac OSX与iOS中也能像其他Objective-C代码一样用Swift编写。不过Alamofire更适合Swift语言风格习惯(Alamofire与AFNetworking可以共存一个项目中,互不影响). </p>    <pre class="brush:cpp;
