Postman CN Modern

CI Postman Windows Node License

中文 · English

中文说明

Postman CN Modern 是一个面向新版 Postman Desktop 的 Windows 优先汉化工具。它延续 hlmd/Postman-cn 的本地覆盖思路，但将旧的 PHP 静态替换流程升级为可维护的 Node CLI、ASAR 安装器、运行时 DOM 本地化器和自动化补词工作流。

强烈建议用于 Postman Desktop 12.x。当前已在 Postman 12.8.4 上重点验证。

Postman 11.x、9.x 或更老版本的文件结构和加载方式差异较大，不建议直接使用当前版本。未来 Postman 13.x 也需要确认兼容后再放开版本范围。

免责声明：本项目是社区维护项目，与 Postman, Inc. 没有关联、授权、赞助或背书关系。Postman 是 Postman, Inc. 的商标。

特性

  • 一个 Windows 入口：双击 install-cn.cmd。
  • 安全安装：不直接修改原始 resources/app.asar。
  • 可恢复：同一个菜单可恢复英文界面。
  • 适配 Postman 12：通过 preload_desktop.js 处理远程渲染的桌面 UI。
  • 自动补词：可从正在运行的 Postman 窗口捕获未汉化可见文本。
  • 自动检测版本：扫描 %LOCALAPPDATA%\Postman\app-* 并选择最新 semver 版本。
  • 有测试覆盖：检测、字典校验、ASAR 解包、安装/恢复、patcher、scanner 等核心逻辑均有测试。

版本支持

Postman 版本 状态 说明
12.8.4 已重点验证 当前主要目标版本
12.x 推荐尝试 字典范围为 >=12.0.0 <13.0.0，新版小版本建议先 dry-run
13.x 暂不支持 需要重新验证 UI 与 preload 结构
11.x 及更早 不建议 文件结构和旧仓库时代差异较大

如果你使用的不是 12.8.4，建议先运行：

npm run cn:detect
npm run cn:dry-run

确认 dry-run 能正常注入 preload_desktop.js 后再安装。

工作原理

Postman 是 Electron 应用。新版 Postman 仍然包含 resources/app.asar，但很多主界面文案会从 desktop.postman.com 远程加载，仅替换本地 bundle 已经无法覆盖主要界面。

本工具采用两层方案：

  1. 解包 Postman 的 resources/app.asar 到临时目录。
  2. 在 preload_desktop.js 注入一个轻量 DOM 本地化器。
  3. 将 patch 后的目录安装为 resources/app。
  4. 将原始 app.asar 重命名为 app.asar.postman-cn.bak。
  5. Electron 启动时加载 resources/app，preload 本地化器在 React 渲染后翻译可见文本、placeholder、title 和 aria-label。

恢复时会删除本工具创建的 resources/app，并把备份的 app.asar.postman-cn.bak 还原为 app.asar。

系统要求

  • Windows 10/11
  • Node.js 20 或更高版本
  • Postman Desktop 安装在 %LOCALAPPDATA%\Postman\app-*
  • 推荐 Postman Desktop 12.x

快速开始

  1. 下载或克隆本仓库。
  2. 完全关闭 Postman。
  3. 双击：
install-cn.cmd
  1. 选择：
1. Install Chinese UI

脚本完成后，正常启动 Postman 即可。

如需恢复英文界面，再次运行 install-cn.cmd 并选择：

2. Restore English UI

菜单还提供：

3. Detect Postman only

高级用户也可以从终端运行：

.\install-cn.cmd install
.\install-cn.cmd restore
.\install-cn.cmd detect

CLI 用法

安装依赖：

npm install

检测 Postman：

npm run cn:detect

预览安装影响，不写入 Postman 安装目录：

npm run cn:dry-run

安装汉化：

npm run cn:install

恢复英文：

npm run cn:restore

运行测试：

npm test

翻译补全工作流

捕获当前 Postman 窗口的未汉化文本：

npm run cn:scan-live

自动扫常见导航入口：

npm run cn:sweep-live

编辑已知安全词条后，重新生成合并字典：

npm run cn:rebuild-dictionary

报告会生成到 reports/untranslated-*.json，该目录不会提交到 Git。

完整流程见 docs/TRANSLATION_WORKFLOW.md。

安全模型

  • 不直接修改 Postman 原始 app.asar。
  • 已存在且不是本工具创建的 resources/app 默认拒绝覆盖。
  • restore 需要本工具生成的 manifest。
  • 安装或恢复前必须关闭 Postman。
  • 不阻止 Postman 官方更新。更新后请重新运行 install-cn.cmd。
  • 图片、canvas、闭合 shadow DOM、账号/云端动态内容可能不在 v1 覆盖范围内。

常见问题

Node.js was not found

请安装 Node.js 20 或更高版本：https://nodejs.org/，然后重新运行 install-cn.cmd。

Postman 仍然是英文

完全关闭 Postman，运行 install-cn.cmd，选择 1，再重新启动 Postman。如果 Postman 已自动更新，请对新版本重新安装汉化。

提示 Postman 正在运行

从托盘退出 Postman，或在任务管理器中结束所有 Postman.exe，然后重试。

Postman 白屏或卡加载

运行 install-cn.cmd，选择 2 恢复英文界面。随后请带上 Postman 版本和安装输出提交 issue。

路线图

  • 扩大 Postman 12.x 界面覆盖范围。
  • 增强自动化 UI 遍历和补词能力。
  • 增加 macOS/Linux locator 和安装支持。
  • 发布 zip 包，降低用户下载和运行门槛。
  • 按 Postman 大版本拆分字典包。

English

Postman CN Modern is a Windows-first Chinese localization tool for recent Postman Desktop builds. It follows the local override idea from hlmd/Postman-cn, but replaces the old PHP static replacement flow with a maintainable Node CLI, ASAR installer, runtime DOM localizer, and automated translation workflow.

This project is best used with Postman Desktop 12.x. It has been primarily verified on Postman 12.8.4.

Postman 11.x, 9.x, and older releases have significantly different file layouts and loading behavior. They are not recommended for this tool. Future Postman 13.x releases should be verified before the version range is expanded.

Disclaimer: This project is community-maintained and is not affiliated with, endorsed by, or sponsored by Postman, Inc. Postman is a trademark of Postman, Inc.

Features

  • One Windows entry: double-click install-cn.cmd.
  • Safe install: does not patch Postman's original resources/app.asar in place.
  • Reversible: restore the English UI from the same menu.
  • Postman 12 ready: handles remote-rendered desktop UI through preload_desktop.js.
  • Automation friendly: captures untranslated visible text from a live Postman window.
  • Version aware: scans %LOCALAPPDATA%\Postman\app-* and selects the latest semver version.
  • Tested core: locator, dictionary validation, ASAR extraction, installer/restore, patcher, and scanner behavior are covered by tests.

Version Support

Postman version Status Notes
12.8.4 Verified Primary target version
12.x Recommended Dictionary range is >=12.0.0 <13.0.0; dry-run first for newer minor versions
13.x Not supported yet Needs UI and preload verification
11.x and older Not recommended File layout differs too much from the current target

If you are not on 12.8.4, run this first:

npm run cn:detect
npm run cn:dry-run

Install only after the dry-run confirms that preload_desktop.js can be injected.

How It Works

Postman is an Electron app. Recent builds still include resources/app.asar, but much of the main desktop UI is loaded from desktop.postman.com. Replacing only local bundle files no longer covers the main UI.

This tool uses a two-layer strategy:

  1. Extract Postman's resources/app.asar to a temporary directory.
  2. Inject a small localizer into preload_desktop.js.
  3. Install the patched unpacked directory as resources/app.
  4. Rename the original app.asar to app.asar.postman-cn.bak.
  5. Electron loads resources/app, and the preload localizer translates visible text, placeholders, titles, and aria labels after React renders.

Restore removes only the override created by this tool and moves app.asar.postman-cn.bak back to app.asar.

Requirements

  • Windows 10/11
  • Node.js 20 or newer
  • Postman Desktop installed under %LOCALAPPDATA%\Postman\app-*
  • Postman Desktop 12.x recommended

Quick Start

  1. Download or clone this repository.
  2. Close Postman completely.
  3. Double-click:
install-cn.cmd
  1. Choose:
1. Install Chinese UI

Start Postman normally after the script finishes.

To restore English later, run install-cn.cmd again and choose:

2. Restore English UI

The same menu also provides:

3. Detect Postman only

Advanced users can run:

.\install-cn.cmd install
.\install-cn.cmd restore
.\install-cn.cmd detect

CLI Usage

Install dependencies:

npm install

Detect Postman:

npm run cn:detect

Preview the patch without writing to Postman's installation directory:

npm run cn:dry-run

Install the Chinese override:

npm run cn:install

Restore the original English app:

npm run cn:restore

Run tests:

npm test

Translation Workflow

Capture untranslated text from the current live Postman window:

npm run cn:scan-live

Sweep common navigation entries:

npm run cn:sweep-live

Regenerate the merged dictionary after editing known translations:

npm run cn:rebuild-dictionary

Reports are written to reports/untranslated-*.json and ignored by Git.

See docs/TRANSLATION_WORKFLOW.md for details.

Safety Model

  • The tool does not patch Postman's original app.asar in place.
  • Existing resources/app directories not created by this tool are refused by default.
  • restore requires the manifest generated during install.
  • Postman must be closed before install or restore.
  • Official Postman updates are not blocked. Re-run install-cn.cmd after an update.
  • Text rendered inside images, canvas, closed shadow DOM, or account/cloud content may remain outside scope.

Troubleshooting

Node.js was not found

Install Node.js 20 or newer from https://nodejs.org/, then run install-cn.cmd again.

Postman is still English

Close every Postman process, run install-cn.cmd, choose option 1, then start Postman again. If Postman auto-updated, reinstall for the new version.

Install failed because Postman is running

Exit Postman from the tray or kill all Postman.exe processes in Task Manager, then retry.

Postman shows a blank loading screen

Run install-cn.cmd, choose option 2, and restore the English UI. Then open an issue with your Postman version and install output.

Roadmap

  • Broader Postman 12.x screen coverage.
  • Better automated UI traversal for translation discovery.
  • macOS and Linux locator/install support.
  • Release zip packages for easier downloads.
  • Optional dictionary packs by Postman major version.
