[bug][plugin-http] Can't fetch containing dots URLs using plugin-http

[lucanisi]

Hi there!

I encountered an issue with @tauri-apps/plugin-http when trying to fetch a URL that contains dots in the path. For example, attempting a fetch on the URL http://localhost:8080/abc.test/test.txt results in the following error:

SyntaxError: The string did not match the expected pattern.

Steps to Reproduce:

1. Set up a simple server (e.g., at http://localhost:8080).
2. Attempt to fetch a resource with a URL containing dots in the path, like http://localhost:8080/abc.test/test.txt.

fetch("http://localhost:8080/abc.test/test.txt");

3. Observe that the fetch fails with the mentioned error.

Additional Observations:

• If I modify the URL to replace the dot with another character, for example, abc-test, the fetch works correctly.
• This behavior seems specific to URLs containing dots in the url path
• The JS log is not very detailed; it simply stops at SyntaxError: The string did not match the expected pattern. without a detailed stack trace. The last point of the stack stops right at the fetch function with no further details.

Attempts done

• Tried using encodeURI and encodeURIComponent of the URL, but it actually made the situation worse.

Sorry for asking you to open an issue. Looks like this is likely not related to dots in the url. I will close this but will re-open if needed.
