Vue代理報(bào)錯(cuò)404問題及解決(vue配置proxy)
Vue代理報(bào)錯(cuò)404問題
問題描述:
代理后出現(xiàn)404:
第一種路徑拼接 /api 情況
const path = require('path'); function resolve(dir) { return path.resolve(__dirname, dir) } module.exports = { publicPath: process.env.NODE_ENV === "production" ? "./" : "/", assetsDir: "assets", configureWebpack: { resolve: { extensions: ['.js', '.vue', '.json'], alias: { '@': resolve('src'), 'assets': resolve('src/assets'), 'css': resolve('src/assets/css'), 'images': resolve('src/assets/images'), 'views': resolve('src/views'), 'components': resolve('src/components'), 'api': resolve('src/api'), 'mixins': resolve('src/mixins'), 'store': resolve('src/store'), 'service': resolve('src/service'), } } }, devServer: { port: 8081, hot: true, // open: 'Chrome', proxy: { // change xxx-api/login => mock/login // detail: https://cli.vuejs.org/config/#devserver-proxy '/api': { target: 'https://www.xxxxxx.com/', changeOrigin: true, secure: true, pathRewrite: { '^/api': '/' } }, }, }, css: { loaderOptions: { css: {}, postcss: { plugins: [ require('postcss-px2rem')({ remUnit: 192 }) ] } } }, productionSourceMap: false, };
使用如下:
結(jié)果如下:
缺點(diǎn) :打包后的請(qǐng)求路徑會(huì)多個(gè) /api
第二種路徑不變情況
這種寫法也可以:
注意:這時(shí)候就按原來(lái)的路徑就可以了;
結(jié)果如下:
缺點(diǎn):配置多個(gè)代理要注意代理的先后順序;
注意點(diǎn)
代理的順序:從前往后匹配的,先匹配到哪個(gè)就用哪個(gè);
新增說明:配置多個(gè)代理怎么搞?

注意.env.development中的配置
NODE_ENV = 'development' # just a flag ENV = 'development' # base api(當(dāng)使用mock.js時(shí),切換dev-api) # VUE_APP_BASE_API = '/dev-api' VUE_APP_BASE_API = '' # vue-cli uses the VUE_CLI_BABEL_TRANSPILE_MODULES environment variable, # to control whether the babel-plugin-dynamic-import-node plugin is enabled. # It only does one thing by converting all import() to require(). # This configuration can significantly increase the speed of hot updates, # when you have a large number of pages. # Detail: https://github.com/vuejs/vue-cli/blob/dev/packages/@vue/babel-preset-app/index.js VUE_CLI_BABEL_TRANSPILE_MODULES = true # 圖片和附件上傳文件夾 VUE_APP_OSS_FOLDER='test/xxx/' # 品牌項(xiàng)目 (這里為了代理,要多加個(gè) /brand,當(dāng)然可以自己定義) VUE_APP_BASE_BRAND_API = '/brand'
配置了 .env.development
中的代理路徑后,這樣api接口js文件中就不用多寫個(gè) /brand
,不用寫成 /brand/saveOrUpdate
,請(qǐng)求路徑也會(huì)存在 /brand
,baseURL拼接的原因,這樣打包也并不影響,畢竟打包的是生產(chǎn)環(huán)境的路徑;
總結(jié)
以上為個(gè)人經(jīng)驗(yàn),希望能給大家一個(gè)參考,也希望大家多多支持腳本之家。
