unity请求json数据并解析

桃扇骨 2022-08-08 06:18 256阅读 0赞

unity3d在跟.net进行http通信的时候，最常见的就是表单数据的提交请求了，但服务器端会返回一坨json数据，这就要求我们在unity中进行json数据的处理了，一般unity中处理json个数数据用的最多的就是LitJSON(它是.net平台下处理SON数据库的类库)。下面我就贴出源码，仅供学习参考！

关于LitJSON的安装和使用，请参考：[http://www.360doc.com/content/13/0117/11/10941785\_260686840.shtml][http_www.360doc.com_content_13_0117_11_10941785_260686840.shtml]

将LitJson.dll放在assets目录下的plugins文件下，如果没有plugins文件就手动创建一个
