使用带@capacitor-community/electron 的 Ionic v5 构建 Electron 应用程序

Question

上周我遇到了以下问题 - 我不仅想将我的 Ionic 项目编译成 android 版本，而且还想编译成电子桌面应用程序。但是，每次部署 packed electron 版本时，我都会出现白屏。

如何重现问题：

# i create simple angular app
ionic start example-app tabs --type angular 
cd example-app
# i add @capacitor-community version of electron, since the original electron is deprecated
npm i @capacitor-community/electron
# required to get a www folder
ionic build
# add electron folder to project
npx cap add @capacitor-community/electron
# now we work inside electron project...
cd electron
# we can build project
npm run build
# we can start live project
npm run electron:start-live
# and now we have crash - just a blank white window
npm run electron:pack

我已经能够在部署版本中看到 window，在 ./electron/src/setup.ts 文件中进行以下更改。您需要找到以下片段：

// Set a CSP up for our application based on the custom scheme
export function setupContentSecurityPolicy(customScheme: string): void {
  session.defaultSession.webRequest.onHeadersReceived((details, callback) => {
    callback({
      responseHeaders: {
        ...details.responseHeaders,
        'Content-Security-Policy': [
          electronIsDev
            ? `default-src ${customScheme}://* 'unsafe-inline' devtools://* 'unsafe-eval' data:`
            : `default-src ${customScheme}://* 'unsafe-inline' data:`,
        ],
      },
    });
  });
}

并将其更改为：

// Set a CSP up for our application based on the custom scheme
export function setupContentSecurityPolicy(customScheme: string): void {
  session.defaultSession.webRequest.onHeadersReceived((details, callback) => {
    callback({
      responseHeaders: {
        ...details.responseHeaders,
        'Content-Security-Policy': [
             `default-src ${customScheme}://* 'unsafe-inline' devtools://* 'unsafe-eval' data:`
        ],
      },
    });
  });
}
