Characters escape when paginating search

[lhcorralo]

I have an internal server and I am executing a search request, with the following URL

http://localhost:5252/search?collections=sentinel-2-l1c&intersects={%22type%22:%22MultiPolygon%22,%22coordinates%22:[[[[-0.99999991,40.00000005],[8.38190317E-8,40.00000005],[8.38190317E-8,39.00000005],[-0.99999991,39.00000005],[-0.99999991,40.00000005]]]],%22crs%22:{%22type%22:%22name%22,%22properties%22:{%22name%22:%22EPSG:0%22}}}&datetime=2022-08-01T00:00:00Z/2022-08-31T23:59:59.999999999Z

The search returns paginated requests. The "links" field is:

"links": [
    {
        "rel": "next",
        "type": "application/geo+json",
        "method": "GET",
        "href": "[http://localhost:5252/search?collections=sentinel-2-l1c&intersects={\"type\":\"MultiPolygon\",\"coordinates\":[[[[-0.99999991,40.00000005],[8.38190317E-8,40.00000005],[8.38190317E-8,39.00000005],[-0.99999991,39.00000005],[-0.99999991,40.00000005]]]],\"crs\":{\"type\":\"name\",\"properties\":{\"name\":\"EPSG:0\"}}}&datetime=2022-08-01T00:00:00Z/2022-08-31T23:59:59.999999999Z&token=next:58f1d6c4-8d35-3227-b86a-dcc6a3500e38](http://localhost:5252/search?collections=sentinel-2-l1c&intersects={%22type%22:%22MultiPolygon%22,%22coordinates%22:[[[[-0.99999991,40.00000005],[8.38190317E-8,40.00000005],[8.38190317E-8,39.00000005],[-0.99999991,39.00000005],[-0.99999991,40.00000005]]]],%22crs%22:{%22type%22:%22name%22,%22properties%22:{%22name%22:%22EPSG:0%22}}}&datetime=2022-08-01T00:00:00Z/2022-08-31T23:59:59.999999999Z&token=next:58f1d6c4-8d35-3227-b86a-dcc6a3500e38)"
    },
    {
        "rel": "root",
        "type": "application/json",
        "href": "http://localhost:5252/"
    },
    {
        "rel": "self",
        "type": "application/json",
        "href": "http://localhost:5252/search?collections=sentinel-2-l1c&intersects={%22type%22:%22MultiPolygon%22,%22coordinates%22:[[[[-0.99999991,40.00000005],[8.38190317E-8,40.00000005],[8.38190317E-8,39.00000005],[-0.99999991,39.00000005],[-0.99999991,40.00000005]]]],%22crs%22:{%22type%22:%22name%22,%22properties%22:{%22name%22:%22EPSG:0%22}}}&datetime=2022-08-01T00:00:00Z/2022-08-31T23:59:59.999999999Z"
    }
]

It can be seen that link "self" escape different characters than link "next" and "previous". In particular, "self" escapes the double quotes.

In addition, characters [ and ] are reserved according to https://developers.google.com/maps/url-encoding?hl=en, and they are not escaped in any case (I have doubts about if characters { and } should be escaped, despite seeming a good idea).

Thanks!

There was a similar issue in stac-fastapi-elasticsearch-opensearch (stac-utils/stac-fastapi-elasticsearch-opensearch#215). It was solved by removing the unquote() call on the parameter string.
