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）-编程知识

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
