Question

我有一个角度应用程序，已使用电子生成器将其转换为桌面应用程序。现在，我试图在其中实现自动更新功能。我不希望电子建造者将更改发布到github存储库。（注意：整个应用程序都在一个私人的github仓库中。）我想手动将必需的.dmg，.zip，.yml文件上传到release标签，并且希望由自动更新程序将其拾取。我该如何实现？

当前，我将源.zip和.tar.gz作为发行标签的一部分。当应用准备就绪时，每当我尝试调用autoUpdater.checkForUpdates()时，都会出现以下错误消息：

这是我的代码：

updater.ts

import { autoUpdater } from 'electron-updater';
import { dialog, BrowserWindow, ipcMain } from 'electron';

const log = require('electron-log');
let downloadProgress: number;
log.transports.file.level = "debug";
autoUpdater.logger = log;

autoUpdater.autoDownload = false;

export function check() {
    autoUpdater.checkForUpdates();

autoUpdater.on('checking-for-update', () => {
    dialog.showMessageBox({
        type: 'info',
        title: 'Update Available',
        message: 'A new version of app is available. Do you want to update now?',
        buttons: ['Update', 'No']
    }, (index) => {
        if (index) {
            return;
        } else {
            autoUpdater.downloadUpdate();

            let proWin = new BrowserWindow({
                width: 350,
                height: 35,
                useContentSize: true,
                autoHideMenuBar: true,
                maximizable: false,
                fullscreen: false,
                fullscreenable: false,
                resizable: false,
                title: 'Downloading Update'
            });
            proWin.loadURL(`file://$(__dirname)/progress`);

            proWin.on('closed', () => {
                proWin = null;
            });

            ipcMain.on('download-progress-request', (e) => {
                e.returnValue = downloadProgress;
            });

            autoUpdater.on('download-progress', (d) => {
                downloadProgress = d.percent;
                autoUpdater.logger.info(downloadProgress);
            });

            autoUpdater.on('update-downloaded', () => {
                if (progressWindow) progressWindow.close();

                dialog.showMessageBox({
                    type: 'info',
                    title: 'Update Ready',
                    message: 'A new version of app is ready. Quit and Install now?',
                    buttons: ['Yes', 'Later']
                }, (index) => {
                    if (!index) {
                        autoUpdater.quitAndInstall();
                    }
                });
            });
        }
    });
});

} 当应用程序准备就绪时，可以通过以下方式从main.ts中调用updater.ts中的check()方法：

app.on('ready', async () => {
   mainWinProcess() // handles all the browser window ops.
   createTray();
   setTimeout(updater.check, 2000); 
});

package.json如下：

{
    "name": "project-web",
    "productName": "Project Web X",
    "version": "1.0.0",
    "author": "applecool",
    "description": "A func app",
    "main": "./main.js",
    "dependencies": {
        "electron-log": "2.2.17",

    },

        "start-mac-setup-dev": "build --mac --config electron-builder-dev.yml",
        "start-mac-setup": "build --mac"
    },
    "devDependencies": {
        "@types/node": "^10.12.9",
        "electron": "3.0.10",
        "electron-builder": "20.36.2",
        "electron-is-dev": "1.0.1",
        "electron-reload": "1.3.0",
        "gulp": "4.0.0",
        "icon-gen": "2.0.0",
        "jimp": "0.5.6",
        "os": "0.1.1",
        "zip-folder": "1.0.0",
        "devtron": "1.4.0"
    },
    "build": {
        "appId": "com.projectweb.x"
    }
}

有人能指出我正确的方向吗？我正在尝试在开发环境中做到这一点。

谢谢。

如果要测试，只需启动本地服务器，然后将文件（dmg，zip，yml，json）放在那里（假设它在localhost：3000上）。然后，调用API .setFeedURL（document here）。

例如：autoUpdater.setFeedURL("http://localhost:3000/latest-mac.json")并呼叫autoUpdater.checkForUpdates()。

电子制造商文档中的注释：

请注意，为了开发/测试不带包装的UI / UX更新该应用程序中需要有一个名为dev-app-update.yml的文件项目的根，与您的发布设置相匹配电子生成器配置（但为Yaml格式）。但这不是建议，最好测试已安装应用程序的自动更新（尤其是在Windows上）。建议将Minio用作以下服务器的本地服务器测试更新。
