要匹配未知数量的路径段,请使用 [...rest]
参数,该参数因与 JavaScript 中的 rest 参数 相似而得名。
¥To match an unknown number of path segments, use a [...rest]
parameter, so named for its resemblance to rest parameters in JavaScript.
将 src/routes/[path]
重命名为 src/routes/[...path]
。路由现在匹配任何路径。
¥Rename src/routes/[path]
to src/routes/[...path]
. The route now matches any path.
将首先测试其他更具体的路由,使其余参数可用作 ‘catch-all’ 路由。例如,如果你需要为
/categories/...
内的页面自定义 404 页面,你可以添加以下文件:¥[!NOTE] Other, more specific routes will be tested first, making rest parameters useful as ‘catch-all’ routes. For example, if you needed a custom 404 page for pages inside
/categories/...
, you could add these files:src/routes/ ├ categories/ │ ├ animal/ │ ├ mineral/ │ ├ vegetable/ │ ├ [...catchall]/ │ │ ├ +error.svelte │ │ └ +page.server.js
在
+page.server.js
文件中,error(404)
在load
中。¥Inside the
+page.server.js
file,error(404)
insideload
.
剩余参数不需要放在最后 — 像 /items/[...path]/edit
或 /items/[...path].json
这样的路由完全有效。
¥Rest parameters do not need to go at the end — a route like /items/[...path]/edit
or /items/[...path].json
is totally valid.
