vue-element-admin请求接口时报错:431 Request Header Fields Too Large
1、使用vue-element-admin框架开发运行后报错431,在网上也找了一些解决方案,有说是生成的Token太大导致的报错,也说有可能是NGINX后台设置的提交大小限制。这里我看了一下文件配置vue.config.js
module.exports = {
publicPath: '/',
outputDir: 'dist',
assetsDir: 'static',
lintOnSave: process.env.NODE_ENV === 'development',
productionSourceMap: false,
devServer: {
port: port,
open: true,
overlay: {
warnings: false,
errors: true
},
// before: require('./mock/mock-server.js')
proxy: {
[process.env.VUE_APP_BASE_API]: {
target: `http://127.0.0.1:${port}`,
changeOrigin: true,
pathRewrite: {
["^" + process.env.VUE_APP_BASE_API]: ""
}
}
},
host: 'localhost'
},
configureWebpack: {
// provide the app's title in webpack's name field, so that
// it can be accessed in index.html to inject the correct title.
name: name,
resolve: {
alias: {
'@': resolve('src')
}
}
},
chainWebpack(config) {
// it can improve the speed of the first screen, it is recommended to turn on preload
// it can improve the speed of the first screen, it is recommended to turn on preload
config.plugin('preload').tap(() => [{
rel: 'preload',
// to ignore runtime.js
// https://github.com/vuejs/vue-cli/blob/dev/packages/@vue/cli-service/lib/config/app.js#L171
fileBlacklist: [/\.map$/, /hot-update\.js$/, /runtime\..*\.js$/],
include: 'initial'
}])
// when there are many pages, it will cause too many meaningless requests
config.plugins.delete('prefetch')
// set svg-sprite-loader
config.module
.rule('svg')
.exclude.add(resolve('src/icons'))
.end()
config.module
.rule('icons')
.test(/\.svg$/)
.include.add(resolve('src/icons'))
.end()
.use('svg-sprite-loader')
.loader('svg-sprite-loader')
.options({
symbolId: 'icon-[name]'
})
.end()
config
.when(process.env.NODE_ENV !== 'development',
config => {
config
.plugin('ScriptExtHtmlWebpackPlugin')
.after('html')
.use('script-ext-html-webpack-plugin', [{
// `runtime` must same as runtimeChunk name. default is `runtime`
inline: /runtime\..*\.js$/
}])
.end()
config
.optimization.splitChunks({
chunks: 'all',
cacheGroups: {
libs: {
name: 'chunk-libs',
test: /[\\/]node_modules[\\/]/,
priority: 10,
chunks: 'initial' // only package third parties that are initially dependent
},
elementUI: {
name: 'chunk-elementUI', // split elementUI into a single package
priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm
},
commons: {
name: 'chunk-commons',
test: resolve('src/components'), // can customize your rules
minChunks: 3, // minimum common number
priority: 5,
reuseExistingChunk: true
}
}
})
// https:// webpack.js.org/configuration/optimization/#optimizationruntimechunk
config.optimization.runtimeChunk('single')
}
)
}
}
发现这里代理的后台请求地址端口为前端框架运行的端口,所请求的结果地址错误了
这样就可以了,如果修改完后还是出现问题,那就可以考虑下开篇说的问题了,可参考浏览器返回431问题分析 - 简书
