网站做seo需要哪些准备seo搜索引擎优化案例

        时光噶然  一晃好多年过去了（干了5年的u3d游戏），记得最后一次使用的版本好像是 unity 2017。 那个是 unity3d for webgl  还需要装个插件。用起来很蛋疼。 最近做一个小项目 在选择是用 Layabox  还是 cocosCreate 的时候 我想起了老战友 Unity3d（因为是3D漫游的项目）。抱着试一试的态度 看了下最新版的 Unity 2023.2.14f1. 试了下 不错呀  现在不用预装 web 插件，就能直接跑 加上  URP  的应用 不光效果好，体验也是更好了！

unity3d build for web

Unable to parse Build/build.framework.js.gz!

Unable to parse Build/build.framework.js.gz!

发布的时候报了错：

看了网上好多人 的方案如下：

•  build 打包 不压缩： 由于是 web 环境，我这边不压缩 是 70m 左右，压缩 是28m, 我个人还是 觉得压缩下好  (不推荐这种方式)
•  Decompression Fallback 选中： 我这边测试这个方案不能

打开的正确姿势：

官方文档这里介绍：

• IIS

  <!--The following server configuration can be used for compressed Web builds without decompression fallback.This configuration file should be uploaded to the server as "<Application Folder>/Build/web.config".NOTE: To host compressed Web builds without decompression fallback, you need to install the "URL Rewrite" IIS module on the server.
  Otherwise, IIS will throw an exception when using this configuration file.
  This module is available at https://www.iis.net/downloads/microsoft/url-rewrite.

• nginx
• apache

应为这边是 IIS 环境我们着重 看下 IIS:

1. URL Rewrite : The Official Microsoft IIS Site ,需要从这里安装
2. 在你发布的目录下 Build 目录新建 web.config 内容就是上面的

配置完毕就能跑起来了：

经测试：火狐 谷歌都ok，edge 浏览器没跑起来。
