uni-app 配置代理 vue.config.js无效的问题 本文通过vite.config.js解决

之前在网上搜了很多配置,比如manifest.json 配置H5跨域请求、vue.config.js配置通通无效,例如下面这个:也是无效

错误示例manifest.json:

"h5" : {
  "devServer" : {
    "https" : false,
      "proxy"  :{
      "/api":{
        "target":"http://localhost:4000",
          "changeOrigin":true,
          "secure":false,
          "pathRewrite":{
          "^/api" : ""
        }
      }
    }
  }
}

错误示例vue.config.js:

module.exports = {
  devServer: {
    proxy: {
      '/api': {
        target: 'http://localhost:8080/api',
		changeOrigin: true,
        pathRewrite: {
          '^/api': ''
        }
      }
    },
  }
}

正确示例:

经过本人多番查找问题总算找到了合适的方法,使用以下配置:(也有版本问题后面会讲):

import {
	defineConfig
} from "vite"
import uni from "@dcloudio/vite-plugin-uni";
 
export default defineConfig({
	plugins: [
		uni()
	],
	server: {
		proxy: {
			'/api': {
				target: 'http://localhost:4000',
				changeOrigin: true,
				rewrite: path => path.replace(/^\/api/, '')
			},
			
		}
	}
})

这套配置可能在网上很多人发,但是都会报错不是这个错误就那个错误,比如这个错误:

Error: Cannot find module '../../../uni-cli-shared/dist'

17:16:59.289 failed to load config from xxx/vite.config.js
17:16:59.308 error when starting dev server:
17:16:59.308 Error: Cannot find module '../../../uni-cli-shared/dist'

等等之类的,我踩过太多了坑了..后来我发现是@dcloudio/vite-plugin-uni版本问题,需要安装指定版本

并且删除manifest.json的所有跨域配置(manifest.json优先级比较高)

{
  "dependencies": {
    "@dcloudio/vite-plugin-uni": "^3.0.0-alpha-4010820240517001",
    "ant-design-vue": "^4.2.1",
    "axios": "^1.6.8",
    "axios-adapter-uniapp": "^0.1.4",
    "echarts": "^5.5.0",
    "mpvue-echarts": "^1.0.0",
    "vite": "^5.2.11"
  }
}

yarn add @dcloudio/vite-plugin-uni@3.0.0-alpha-4010820240517001

然后总算解决了这个问题

如果对你有帮助的话点个赞.谢谢了
