net::ERR_CONNECTION_REFUSED

[stackedCG]

Hi I am receiving the error net::ERR_CONNECTION_REFUSED from my iframe which contains a locally added html file that uses external resources which are relative to the loaded html itself.

Here are the configurations I have:

• src > main.js

import { convertFileSrc } from "@tauri-apps/api/core";
import { open } from "@tauri-apps/plugin-dialog";

window.onload = async () => {
  document.querySelector("#fileOpener").addEventListener("click", async (e) => {
    file = await open({
      multiple: false,
      directory: false,
    });

    document.querySelector("iframe").src = convertFileSrc(file);
  });
};

• tauri.conf.json

    "security": {
      "csp": "default-src 'self' ipc: http://ipc.localhost; frame-src 'self' asset: http://asset.localhost; style-src 'self' asset: http://asset.localhost; script-src 'self' asset: http://asset.localhost",
      "assetProtocol": {
        "enable": true,
        "scope": ["*"]
      }
    }

Let me know if I miss an information detail needed to solve this issue, thank you!

Also can I use convertfilesrc multiple times, so for example in the sample above I used it to open files, but on the second attempt in opening another file it does not work anymore. Is there any other way to use convertfilesrc multiple times?

The output of the tauri info command would be appreciated.

which contains a locally added html file that uses external resources which are relative to the loaded html itself.

ah missed this one. the asset protocol can't really handle that http-server-like use at the moment. So even if the initial connection works, loading all assets may fail. I think i misunderstood you. does the file in the iframe try to load files as well?

tauri.conf.json

can you try "scope": ["**/*"] instead? "*" only matches a single level iirc.

[stackedCG]

does the file in the iframe try to load files as well?

No it does not load file but it had resources relative to it.

can you try "scope": ["**/"] instead? "" only matches a single level iirc.

Unfortunately, it did not work on my end as well.

This is the entirety of the html I am trying to load on the iframe:

[FabianLars]

yeah, the asset protocol can't handle that so it's not worth to look more into the error.

you need either your own custom protocol that behaves more like an http server, host your own localhost server (in rust or as a sidecar), or maybeee try using the tauri protocol (by adding those files into devUrl / frontendDist)

[stackedCG]

Oh thats unfortunate, do you have any documentation I could check for creating a http server/creating localhost server? It would be awesome if you could share a documentation that can also support mobile, since the localhost plugin does not support mobile versions.

Or is there a way to use the tauri protocol programatically?
