historyApiFallback 在 Webpack 开发服务器中不起作用
historyApiFallback doesn't work in Webpack dev server
我使用 Webpack 开发服务器并且 browserHistory in React Router to manipulate with urls by HTML5 History API. historyapifallback-option 在我的 webpack 配置文件中不起作用。刷新 http://localhost:8080/users
或 http://localhost:8080/products
我得到 404.

我今天遇到了同样的问题。
让webpack.config.js中的config:output.publicPath
等于devServer.historyApiFallback.index和指出html文件路由。我的webpack-dev-server版本是 1.10.1 并且运行良好。 http://webpack.github.io/docs/webpack-dev-server.html#the-historyapifallback-option不行,必须指出html文件路径。
例如
module.exports = {
entry: "./src/app/index.js",
output: {
path: path.resolve(__dirname, 'build'),
publicPath: 'build',
filename: 'bundle-main.js'
},
devServer: {
historyApiFallback:{
index:'build/index.html'
},
},
};
historyApiFallback.index 表示当 url 路径不匹配真实文件时,webpack-dev-server 使用 historyApiFallback.index 中的文件配置在浏览器中显示而不是 404 页面。然后所有关于你的路线改变的事情让你的js使用react-router来做。
参考:https://webpack.js.org/configuration/dev-server/#devserver-historyapifallback
这适用于任何 react-router
您必须添加 historyApiFallback: true
module.exports = {
cache: true,
entry: "./index.js",
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, 'public')
},
context: SRC,
devServer: {
contentBase: path.resolve(__dirname, 'public/assets'),
stats: 'errors-only',
open: true,
port: 8080,
compress: true,
historyApiFallback: true
},
...
}
output: {
...
publicPath: "/"
},
添加 public 路径为我解决了这个问题
我遇到了这个问题,只能使用 index: '/'
和 webpack 4.20.2
来修复它
historyApiFallback: {
index: '/'
}
这里发生了一件非常棘手的事情!
404 可以是下面两个完全不同的。可以打开Chrome的Network标签,看看是初始请求404,还是里面的assets。
如果不怕终端的话,也可以curl -v http://localhost:8081/product
看看实际的HTTP响应码
案例 1:初始 HTML 页面上的 404
这是historyFallbackApi设置不正确的情况。
通常只有 historyApiFallback: true
应该在 Webpack 的 devServer
配置中工作。 (source) Yet, if you happen to have a custom output
folder, you have to set the index
property of historyApiFallback
to the same path, as advised by the other answers on this question like or .
案例 2:资产上的 404(例如 bundle.js
或 vendor.js
)
这个很有意思!
在这种情况下,您实际上得到了初始 HTML(即,如果您在 URL 之前添加 view-source:
成为 view-source:http://localhost:8081/admin
,您会看到 HTML、and/or curl
命令显示 HTML),但该页面在浏览器中不起作用。
historyApiFallback 所做的,听起来像是魔术,实际上只是将 Express 服务器的 req.url
设置为 index.html
文件,因为域内的任何传入 GET 请求。 (The main two lines in the Source Code)
但是,如果您的资产路径是相对的(例如,在查看源代码中,您会看到 <script src="vendor.js"></script>
)AND 您登陆的路径不是在与索引相同的路径深度(例如,当主服务器处于 http://localhost:8081/admin
时,您试图加载 http://localhost:8081/admin/user/12/summary
),发生的事情是它找不到您的 JavaScript 的 .js 文件代码。 (在我的例子中 http://localhost:8081/admin/user/12/vendor.js
)
请注意,这里处理 HTML5 历史记录的任何路由器(反应路由器或 vue 路由器)都知道如何在初始加载时将内部路径初始化为 document.location.href
。但是,它不知道正确更新资产路径的“根”在哪里。 (就责任而言,这甚至可能不是它的工作。)因此,资产的路径将根据 URL 的路径计算,而不是 index.html
的路径!因此,对于没有绝对 /
前缀的 src="vendor.js"
,它会尝试查找 /admin/user/12/vendor.js
而不是 /vendor.js
.
这里你需要做的是确保你的WebPack的output
路径是绝对路径并且以/
开头,所以不管着陆URL,它总是有效的。即在 HTML 来源中总是 <script src="/vendor.js"></script>
。
为此,您必须将 output.publicPath
设置为绝对路径(有或没有域)。您可以通过上面的 view-source:
或 curl
技术来验证这一点。 :)
如果您发现某些 路径有效而其他路径无效,您可能违反了“点规则”。每 the docs:
When using dots in your path (common with Angular), you may need to
use the disableDotRule
:
webpack.config.js
module.exports = {
//...
devServer: {
historyApiFallback: {
disableDotRule: true,
},
},
};
