# FileProtocol
|
|
|
|
## Click the link
|
|
|
|
Normally, link like
|
|
|
|
```wikitext
|
|
[ext[外部文件|file:///Users/linonetwo/Downloads/(OCRed)奖励的惩罚 (（美）科恩著) (Z-Library).pdf]]
|
|
|
|
[ext[外部文件夹|file:///Users/linonetwo/Downloads/]]
|
|
```
|
|
|
|
Will become external link that will open new window, so this feature is handled in `handleOpenFileExternalLink` in `src/services/view/setupViewEventHandlers.ts`.
|
|
|
|
## Load the file content
|
|
|
|
Image syntax like
|
|
|
|
```wikitext
|
|
[img[file://./files/1644384970572.jpeg]]
|
|
```
|
|
|
|
will ask `view.webContent` to send a request, which will be handled in `handleFileProtocol` in `src/services/view/setupViewSession.ts`.
|
|
|
|
We can switch to this
|
|
|
|
```ts
|
|
public async handleFileProtocol(request: GlobalRequest): Promise<GlobalResponse> {
|
|
logger.info('handleFileProtocol() getting url', { url: request.url });
|
|
const { pathname } = new URL(request.url);
|
|
logger.info('handleFileProtocol() handle file:// or open:// This url will open file in-wiki', { pathname });
|
|
let fileExists = fs.existsSync(pathname);
|
|
logger.info(`This file (decodeURI) ${fileExists ? '' : 'not '}exists`, { pathname });
|
|
if (fileExists) {
|
|
return await net.fetch(pathname);
|
|
}
|
|
logger.info(`try find file relative to workspace folder`);
|
|
const workspace = await this.workspaceService.getActiveWorkspace();
|
|
if (workspace === undefined) {
|
|
logger.error(`No active workspace, abort. Try loading pathname as-is.`, { pathname });
|
|
return await net.fetch(pathname);
|
|
}
|
|
const filePathInWorkspaceFolder = path.resolve(workspace.wikiFolderLocation, pathname);
|
|
fileExists = fs.existsSync(filePathInWorkspaceFolder);
|
|
logger.info(`This file ${fileExists ? '' : 'not '}exists in workspace folder.`, { filePathInWorkspaceFolder });
|
|
if (fileExists) {
|
|
return await net.fetch(filePathInWorkspaceFolder);
|
|
}
|
|
logger.info(`try find file relative to TidGi App folder`);
|
|
// on production, __dirname will be in .webpack/main
|
|
const inTidGiAppAbsoluteFilePath = path.join(app.getAppPath(), '.webpack', 'renderer', pathname);
|
|
fileExists = fs.existsSync(inTidGiAppAbsoluteFilePath);
|
|
if (fileExists) {
|
|
return await net.fetch(inTidGiAppAbsoluteFilePath);
|
|
}
|
|
logger.warn(`This url can't be loaded in-wiki. Try loading url as-is.`, { url: request.url });
|
|
return await net.fetch(request.url);
|
|
}
|
|
```
|
|
|
|
if
|
|
|
|
```ts
|
|
await app.whenReady();
|
|
protocol.handle('file', nativeService.handleFileProtocol.bind(nativeService));
|
|
```
|
|
|
|
works. But currently it is not. `protocol.handle('file'`'s handler won't receive anything. |
