Okio库是一个由square公司开发的，它补充了java.io和java.nio的不足，以便能够更加方便，快速的访问、存储和处理你的数据。而OkHttp的底层也使用该库作为支持。而在开发中，使用该库可以大大给你带来方便。

目前，Okio的最新版本是1.6.0，gradle的引用如下

  1. <code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">
  2. compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'com.squareup.okio:okio:1.6.0'</span>
  3. </code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

Okio中有两个关键的接口，Sink和Source，这两个接口都继承了Closeable接口；而Sink可以简单的看做OutputStream，Source可以简单的看做InputStream。而这两个接口都是支持读写超时设置的。结构图如下

这里写图片描述

它们各自有一个支持缓冲区的子类接口，BufferedSink和BufferedSource，而BufferedSink有一个实现类RealBufferedSink,BufferedSource有一个实现类RealBufferedSource；此外，Sink和Source它门还各自有一个支持gzip压缩的实现类GzipSink和GzipSource；一个具有委托功能的抽象类ForwardingSink和ForwardingSource；还有一个实现类便是InflaterSource和DeflaterSink，这两个类主要用于压缩，为GzipSink和GzipSource服务；整体的结构图如下

这里写图片描述

BufferedSink中定义了一系列写入缓存区的方法，比如write方法写byte数组，writeUtf8写字符串，还有一些列的writeByte，writeString，writeShort，writeInt，writeLong，writeDecimalLong等等方法；

BufferedSource定义的方法和BufferedSink极为相似，只不过一个是写一个是读，基本上都是一一对应的，如readUtf8，readByte，readString，readShort，readInt等等等等。这两个接口中的方法有兴趣的点源码进去看就可以了。

而这两个支持缓冲区的接口的实现类RealBufferedSink和RealBufferedSource都是通过包装一个Sink+Buffer或者Source+Buffer来进行实现的。如下图所示

这里写图片描述

拿RealBufferedSink来举例，实际调用的write的一系列方法，都是直接的对成员变量buffer进行的操作，当写入buffer成功后，最后会调用一个方法将buffer中的内容写入到sink中去，我们随便拿一个方法看一下

复制代码

可以看到，首先会判断closed成员变量是否是标记着关闭，如果已经关闭了则扔出一个异常，否则将内容写入到buffer，写入完成后调用了一个emitCompleteSegments的方法，该方法中做了什么呢,没错，就是将buffer中的内容写入到sink成员变量中去，然后将自身返回。

这两个实现类的内部的所有方法都是类似的，这里不一一展开。

而这一切的背后都是一个叫做Buffer的类在支持着缓冲区,Buffer是BufferedSink和BufferedSource的实现类，因此它既可以用来读数据，也可以用来写数据，其内部使用了一个Segment和SegmentPool，维持着一个链表，其循环利用的机制和Android中Message的利用机制是一模一样的。

内部一个成员变量next指向链表下一个元素，take方法首先判断池中是否存在可用的，存在则返回，不存在则new一个，而recycle则是将不再使用的Segment重新扔到池中去。从而达到一个Segment池的作用。

而Okio暴露给外部使用的类便是Okio这个类，其内部有大量的静态方法,包括通过一个Source获得BufferedSource，通过一个Sink获得一个BufferedSink。这个过程很简单，我们调用Okio的buffer方法即可返回我们需要的，如下

  1. <code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">
  2. Okio<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.buffer</span>(sink)
  4. Okio<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.buffer</span>(source)
  5. </code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>
复制代码

但是上面两个方法需要传递一个Sink或者Source，那么这个Sink和Source又是如何获得的呢。其实方法也在Okio这个类中。我们可以调用sink方法获得一个Sink，调用source方法获得一个Source，而数据的来源或者目的可以是一个File，一个输入或者输出流，一个Socket链接等等。如下

  1. <code class="hljs vhdl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">
