Unity的Json解析<一>--读取Json文件

因为需要做一个外部文件配置，考虑了XML和Json，而5.3版本对Json做了更新，所以就尝试一下。 

版本更新的Json部分介绍哦： [Unity5.3版本更新的Json部分 ]

Json的在线编辑

Json parser :http://json.parser.online.fr/ 

Json在线编辑：http://www.kjson.com/jsoneditor/?f=1

第二个是可以直接下载保存到本地的，此操作甚好啊！

JsonUtility

先看看，在Unity中，我们在其Json工具类中，可用的函数，总共就5个，好少啊！不过，simple is better.

可以看到，主要就是创建对象的和变成Json格式的两个类型。

准备工作

我们需要一个Json文件，这是主角啊，就是要读取其内容啊。 

好了。我随便写了个，命名为Test.json放到了我的.\Assets\Resources\目录下； 

Json文件内容如下：

<code class="hljs json 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;">{"<span class="hljs-attribute" style="box-sizing: border-box;">gameName</span>":<span class="hljs-value" style="box-sizing: border-box;"><span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"JSON Serializer Test"</span></span>,"<span class="hljs-attribute" style="box-sizing: border-box;">version</span>":<span class="hljs-value" style="box-sizing: border-box;"><span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"1.0"</span></span>,"<span class="hljs-attribute" style="box-sizing: border-box;">isStereo</span>":<span class="hljs-value" style="box-sizing: border-box;"><span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"false"</span></span>,"<span class="hljs-attribute" style="box-sizing: border-box;">isUseHardWare</span>":<span class="hljs-value" style="box-sizing: border-box;"><span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"true"</span></span>,"<span class="hljs-attribute" style="box-sizing: border-box;">statusList</span>":<span class="hljs-value" style="box-sizing: border-box;">[{"<span class="hljs-attribute" style="box-sizing: border-box;">name</span>":<span class="hljs-value" style="box-sizing: border-box;"><span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"test"</span></span>,"<span class="hljs-attribute" style="box-sizing: border-box;">id</span>":<span class="hljs-value" style="box-sizing: border-box;"><span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"1u702"</span></span>}]</span>}</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></ul><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></ul>

创建对象类

首先，我们需要创建一个对象类，用来存放从Json文本中读取的内容。 

给这个类命名为GameStatus.cs

<code class="hljs cs 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;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">using</span> UnityEngine;
<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">using</span> System;
<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">using</span> System.Collections;

}

</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><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li><li style="box-sizing: border-box; padding: 0px 5px;">12</li><li style="box-sizing: border-box; padding: 0px 5px;">13</li><li style="box-sizing: border-box; padding: 0px 5px;">14</li><li style="box-sizing: border-box; padding: 0px 5px;">15</li><li style="box-sizing: border-box; padding: 0px 5px;">16</li><li style="box-sizing: border-box; padding: 0px 5px;">17</li><li style="box-sizing: border-box; padding: 0px 5px;">18</li><li style="box-sizing: border-box; padding: 0px 5px;">19</li><li style="box-sizing: border-box; padding: 0px 5px;">20</li><li style="box-sizing: border-box; padding: 0px 5px;">21</li><li style="box-sizing: border-box; padding: 0px 5px;">22</li></ul><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><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li><li style="box-sizing: border-box; padding: 0px 5px;">12</li><li style="box-sizing: border-box; padding: 0px 5px;">13</li><li style="box-sizing: border-box; padding: 0px 5px;">14</li><li style="box-sizing: border-box; padding: 0px 5px;">15</li><li style="box-sizing: border-box; padding: 0px 5px;">16</li><li style="box-sizing: border-box; padding: 0px 5px;">17</li><li style="box-sizing: border-box; padding: 0px 5px;">18</li><li style="box-sizing: border-box; padding: 0px 5px;">19</li><li style="box-sizing: border-box; padding: 0px 5px;">20</li><li style="box-sizing: border-box; padding: 0px 5px;">21</li><li style="box-sizing: border-box; padding: 0px 5px;">22</li></ul>

需要一个读取类

这个写了一个静态类，以后也可添加写的内容 

名字为LoadJson.cs

说明：代码被注释掉的部分，是从网上找的，解析Json为二进制格式，然后在反序列化为字符串，结果，可能是编码格式问题，不能正确的反序列化，总是报错。 

我表示无奈，只好从写实使用了StreamReader来处理。

调用

调用蛮简单的，就是在Update中，使用L键来加载Json文件。 

代码如下：

<code class="hljs cs 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;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">using</span> UnityEngine;

}

<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">if</span> (Input.GetKeyDown(KeyCode.L))
{
GameStatus status = LoadJson.LoadJsonFromFile();
Debug.Log(status);
}
}

测试结果

在场景中，建立一个空对象，然后把ReadJson拖拽到对象上，运行，按下L键，就可以使用断点查看，当然也后Log输出。

结果如下图：
