本文主要是介绍geecg-uniapp 同源策略 数据请求 获取后台数据 进行页面渲染 ui库安装 冲突解决（3），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一，同源策略
（1）首先找到env 要是没有env 需要创建一个替换成后端接口
（2）因为他封装了 先找到 http 请求位置一级一级找 然后进行接口修改
（3）appUpdata 修改接口 运行即可
（4）接口展示
二，数据请求
接口请求路径展示
（1）创建页面 ，定义请求方式 ， 因为他这个封装过 ，所以我们只能跟固有的进行数据请求
报错了我们解决一下 看完整路径我们发现我们复制多了（路径是拼接的）
（2）正确的写法展示
（3）又报错了 是请求错了 所以注意一下是 post 还是 get
（4）正确的写法展示
三，ui库安装
（1）我查了文档才知道他这个是用一个需要下一个ui组件 太麻烦了 所以直接下载一个完整的
跟着教程 安装运行 ： uni-app官网 (dcloud.net.cn)
（2）下载插件 地址 ： uni-ui - DCloud 插件市场
四，冲突解决
（1）因为之前封装的时候 采用的是单独下载 我们又进行了全局安装 这样的话会报错，有冲突
（2）解决冲突
1，首先清空 components 下载的ui 数据
2，根据报错位置，找到对应的页面，注销引用的 ui 组件
3，找到main.js 注销引用的 ui 组件 以及自定义的组件
4，运行 
五，获取后台数据 进行页面渲染
