Properly encode/decode the percentage character (% -> %25) across browsers and upon initial navigation #2725
Comments

In most cases, we can avoid using special characters in development. But if we got decode error, I think we should catch it manually and try to find the closest asterisk match. |

I recommend adding the following testcases, which seem to be extra nasty: Also, this should be tested with server-side-rendering. It looks like this whole thing only works if the |

Not sure, if this is the same issue, but initial navigation for routes with percent-encoded characters does not work. The problem was initially reported in nextcloud/tasks#479. Have a look at this example: <!DOCTYPE html>

<div id="app">
<router-link
v-for="item in items"
:to="{name: 'items', params: {itemId: item.id }}"
:key="item.id"

Go to {{ item.name }}

<router-view></router-view>

const items = [

{
id: 'item2_with_ö',
name: 'Item2',
},
{
id: 'item3_with_escaped_%C3%B6',
name: 'Item3',
},
]
const ItemsComponent = Vue.component('Items', {
name: 'Items',
props: {
itemId: {
type: String
}
},
computed: {
item: function() {
return items.find(item => item.id === this.itemId)
},
},
template: `
<div v-if="item">
<span>{{ item.id }}</span>
<span>{{ item.name }}</span>
</div>
<div v-else>
<span>Item not found</span>
<span>ItemId: {{ itemId }}</span>
</div>
`
})
const routes = [
{ name: 'items',
path: '/items/:itemId',
component: ItemsComponent,
props: true,
},

</html>Clicking the links works fine, the correct item is loaded and the route-view shows the correct item. But if you reload the page after clicking on I would appreciate some feedback if this is the same issue described here or not. Thanks a lot! |
onDecode: (req) => {
let url = req.url
try {
url = decodeURI(req.url)
}
catch (error) {
// Rethrow error
if (error.message !== 'URI malformed') {
throw error
}
url = decodeURI(unescape(req.url))
// Fix url also on Nuxt side
req.url = url
}
return url
}I had issues with ISO urls and fixed it like that. |

@alanaasmaa May I ask where to put / how to use |
@raimund-schluessler You have to use a version that is not yet released. Then in nuxt config redirect: {
rules: [
{ from: /^\/page(?:\/?)(?:\?(.*))?$/, to: '/?$1' },
],
onDecode: (req) => {
let url = req.url
try {
url = decodeURI(req.url)
}
catch (error) {
// Rethrow error
if (error.message !== 'URI malformed') {
throw error
}
url = decodeURI(unescape(req.url))
// Fix url also on Nuxt side
req.url = url
}
return url
},
onDecodeError: (error, req, res, next) => next(error)I also had to nuke node_modules |

I've seen the issue has been fixed on 4.x. It is expected to be fixed on the current release 3.3.X? If not, is there a release date for v4.x (I could not manage to find it)? I have some projects which I have to deliver soon, and I would apreciate the information in order to wait for the fix, or trying to remove the percentatge from the path params; which will cause me many troubles :). Thank you very much |

Currently, the percentage character creates multiple issues and inconsistencies. This is partly due to:
%is forbidden as part of the pathname in the URL per its spec (https://url.spec.whatwg.org/#path-state) if not escapedIn Vue router, we have multiple inconsistencies between asterisk path, param paths and regular path regarding escaping these characters and whether the navigation is initial or triggered by a push/router-link
