『练手』手写一个独立Json算法 JsonHelper

背景：

> 一直使用 Newtonsoft.Json.dll 也算挺稳定的。

> 但这个框架也挺闹心的：

> 1、影响编译失败：https://www.cnblogs.com/zihuxinyu/archive/2013/05/06/3063181.html （我也经常遇到）

> 2、WinCE版本（小众用户）太大：Newtonsoft.Json.Compact.dll 352kb 

> 3、自己写一个微型框架，在通讯方面 要用到Json：一个 100k 的框架，引用一个 400k 的 Newtonsoft.Json.dll —— 总感觉 尾大不掉。

>4、不知道 目标类型，我只想将 Json反序列化成 List 和 Hash 的结构 —— 传说中的 万能结构，Newtonsoft.Json.dll 支持得不友好。

 

于是一咬牙，花 9个小时，手写了一个 Json算法：

> 基本支持 Newtonsoft.Json.dll 的 一切正反Json序列化：对象（字典）、集合、元数据。

> 可以将任意 Json 转换成 List 和 Hash 的 组合结构。

> 性能只有 Newtonsoft.Json.dll 的 1/3 （超长Json反序列化， JsonHelper：10000次/秒，Newtonsoft.Json.dll 性能是 30000次/秒）。

> 性能我已经满意了，源码 和 性能截图 如下。

 

性能测试截图：

超长Json反序列化：

JsonHelper 性能为 10W次 12.7秒，Newtonsoft.Json.dll 性能为 10W次 3.7秒。

 

手写一个嵌套实体 10W次 反序列化性能：

JsonHelper 性能为 10W次 7.8秒，Newtonsoft.Json.dll 性能为 10W次 1.3秒。

 

手写一个嵌套实体 10W次 序列化：

JsonHelper 性能为 10W次 2.6秒，Newtonsoft.Json.dll 性能为 10W次 1.2秒。

相关思考：

其实，不想用 Newtonsoft.Json.dll  的最大原因是：自己的框架 不想引用太多 第三方的东西，能完全独立最好。

而且，自己的一个框架 100KB，引用一个 400KB 的 Newtonsoft.Json.dll  —— 会让人觉得：你的框架70% 的功能都是 Newtonsoft.Json.dll  实现的，你只是做了个封装而已。

 

如何技能保证 框架的独立性，又能利用到 Newtonsoft.Json.dll  的性能呢？

方案如下：

> 启用 Emit 高速反射 （性能逼近 原生调用）

> 调用 JsonHelper 时，先尝试反射 Newtonsoft.Json.dll  是否存在，如果存在 就用 Emit 调用 Newtonsoft.Json.dll 

> 如果不存在，则使用 JsonHelper 的自带算法。

> 这样，似乎就能达到 想要的目的。

 

 

 

代码 1300行 就实现了 Json算法，但是 没啥技术含量 和 实用通用含量（可能小众用户用得到） —— 不敢发布到 博客园首页。

2018-08-08，将之前的 字符串解析算法 的核心函数，替换成了 新写的 栈结构字符串解析算法。

—— 性能直接逼近 Json.Net （Json.Net 之前测试的是 10W次 3.7秒， 之前的解析算法是 10W次 12秒 —— 这次的新算法是 4.2秒）

什么是 栈结构字符串：

> 具备嵌套逻辑的 字符串， Xml、Json、PDF的属性串  都属于 栈结构的字符串

> 这次，是因为 有这样一段 PDF属性串需要解析 —— 如果像之前的 JsonHelper 那样，写专用解析算法 特别废脑细胞【桌子一拍，劳资要写一个 通用栈结构字符串解析算法】。

栈结构字符串解析算法 的 调用方式：

 1             //创建一个 栈结构字符串 解析方案
 2             StrStack stack = new StrStack();
 3             stack.RemoveEmptyAndLineEnd = true;
 4             stack.SetHasChildRule('{', '}', null);
 5             stack.SetHasChildRule('[', ']', null);
 6             stack.SetNoChildRule('"', '"', (l, i, c, s) => { return i <= 0 || l[i - 1] != '\\'; });
 7             stack.SetNoChildRule('\'', '\'', (l, i, c, s) => { return i <= 0 || l[i - 1] != '\\'; });
 8             stack.SetConstRule("null", null);
 9             stack.SetConstRule("true", null);
10             stack.SetConstRule("false", null);
11             stack.SetNumericRule();
12             stack.SetCharRule(';', null);
13             stack.SetCharRule(',', null);
14             stack.SetCharRule(':', null);
15 
16             //通过方案, 解析出所有 栈结构对象(包括嵌套逻辑)
17             List<StrStackObject> listItem = stack.Analyze(str);
18             StrStackObject item = listItem[0];
19 
20             //栈对象 和 嵌套逻辑有了, 接下来就是转换成 自己的 Json算法对象、 PDF算法对象了...
