[GitHub] [cordova-plugin-file] realtebo opened a new issue, #552: @7.0.0 - GET http:///__cdvfile_temporary__/ failed
realtebo opened a new issue, #552:
URL: https://github.com/apache/cordova-plugin-file/issues/552
# Bug Report
## Problem
I'm using fileEntry.toLocalURL() to find where is placed a downloaded image, so I can show it to the user.
I'm using this path as img src.
### What is expected to happen?
Image is loaded from device as showed to the user
### What does actually happen?
I got a 404
## Information
<!-- Include all relevant information that might help understand and reproduce the problem -->
The nativeUrl of the file is `file:///data/user/0/it.realtebo.offline/cache/0.jpg`
I verified with adb shell that file exists and is readable from my app
The .toInternaURL() and the .toURL() gives me same path: `http://192.168.56.1:9400/__cdvfile_temporary__/0.jpg`
### Command or Code
<!-- What command or code is needed to reproduce the problem? -->
Having already a `fs` which is a `DirectoryEntry` obtained as
```
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fs) {
}
```
And having `image` as an object containing a `imageUrl` to download, I use this code to save the file to storage
This portion works well. I have files succesfully saved said before.
```
/ Scarico l'immagine
let imageUrl = image.download_url;
console.log("Scarico il file " + imageUrl);
const {
data: imageData,
error: imageError,
statusCode: imageStatusCode,
} = await useFetch(imageUrl).get().blob();
if (imageStatusCode.value == 404) {
// console.log("Immagine non trovata: " + imageUrl, imageStatusCode.value);
return;
}
if (imageError.value) {
// console.log("imageError ", imageError.value);
return;
}
// Posso proseguire col salvataggio su disco
// console.log("Immagine scaricata");
// Salvo su file l'immagine appena scaricata
fs.root.getFile(
path,
{ create: true },
// file creato con successo
function (newFileEntry) {
console.log("Ho creato il file", newFileEntry);
newFileEntry.createWriter(function (newFileWriter) {
newFileWriter.onwriteend = function () {
console.log("Successful file write...");
};
newFileWriter.onerror = function (e) {
console.log("Failed file write: " + e.toString());
};
newFileWriter.write(imageData.value);
localFileUrls[image.id] = getImageSource(newFileEntry);
});
},
// file non creato per un altro errore, damn
function (newFileError) {
console.log("Errore in fase di creazione del nuovo file", newFileError);
}
);
```

This worked for me, when I came across the same issue.
I load HTML from a specific IP address on a specific port when I am doing development, to get a hotreload environment.
Before I write a check for this that does a string replace, is there a better way of handling this use case? Could `toURL() ` not always return `http://localhost`, since this is always required by `WebViewAssetLoader` (which seems to be the only use-case for `toURL()` anyway...). Thoughts?

I suppose you are loading a html from http://192.168.56.1:9400/
`http://192.168.56.1:9400/__cdvfile_temporary__/0.jpg` will not be intercepted by `WebViewAssetLoader`, you should replace the origin to `localhost` (`http://localhost/__cdvfile_temporary__/0.jpg`), then the `<img>` node will display the image

In case it is useful to anyone, a neat (and quick) way of replacing the required parameters without needing to faff with a regex is:
```
const fileURL = await resolveLocalFilesystemURL(fileEntry);
if (process.env.NODE_ENV === 'development') { // Whatever runtime env detection you need
const url = new URL(fileURL);
url.host = 'localhost';
url.port = '';
return url.toString();
}
```
