Ubuntu Postman配置步骤

Installing Postman on Ubuntu
Postman can be installed on Ubuntu via three methods: Snap (recommended for simplicity), manual download (for custom versions), or PPA (for package manager integration). Below are detailed steps for each:

1. Install via Snap (Recommended)

Snap is a universal package manager for Linux that simplifies installation and updates.

• Update System Packages: Run sudo apt update && sudo apt upgrade to ensure your system is up-to-date.
• Install Snapd (if not installed): Execute sudo apt install snapd to install the Snap daemon.
• Install Postman: Use the command sudo snap install postman to install Postman. The application will appear in your application menu.
• Launch Postman: Open it from the application menu or run postman in the terminal.

2. Manual Download & Installation

For users who prefer specific versions or offline installation:

• Download the Installer: Visit the Postman website, select the Linux version (.tar.gz), and save it to your ~/Downloads folder.
• Extract the Archive: Open a terminal, navigate to the Downloads folder (cd ~/Downloads), and run sudo tar -xzf Postman-linux-x64-*.tar.gz -C /opt/ (replace * with the actual version number). This extracts Postman to /opt/Postman.
• Create a Symbolic Link: To run Postman from the terminal, create a link with sudo ln -s /opt/Postman/Postman /usr/local/bin/postman.
• Add a Desktop Shortcut (Optional): For easy access from the application menu, create a .desktop file:

  sudo nano /usr/share/applications/postman.desktop
  

  Paste the following content (update the path if needed):

  [Desktop Entry]
  Encoding=UTF-8
  Name=Postman
  Exec=/opt/Postman/Postman
  Icon=/opt/Postman/app/resources/app/assets/icon.png
  Terminal=false
  Type=Application
  Categories=Development;
  

  Save (Ctrl+O, Enter) and exit (Ctrl+X). Update the desktop database with sudo update-desktop-database.
• Launch Postman: Run postman in the terminal or find it in the application menu.

3. Install via PPA (Alternative)

Some users may prefer using a Personal Package Archive (PPA) for package management:

• Add the Postman PPA: Run sudo add-apt-repository https://dl.bintray.com/postman/apt and confirm with Enter.
• Update Package Lists: Execute sudo apt update to refresh the package index.
• Install Postman: Use sudo apt install postman to install the application. Launch it from the application menu or terminal.

Configuring Postman
After installation, configure essential settings to optimize Postman for your workflow:

1. Set Up Proxy (Optional)

If you’re behind a corporate proxy, configure Postman to use it:

• Open Postman and click the gear icon (⚙️) in the top-right corner to open Settings.
• Navigate to the General tab.
• Under the Proxy section, enter your Proxy Server Address and Port.
• If your proxy requires authentication, check Proxy authentication and provide your Username and Password.
• Click Save to apply changes.

2. Configure Environment Variables (Optional)

Environment variables help manage API keys, base URLs, and other sensitive data across requests:

• Open Postman and click the gear icon (⚙️) > Manage Environments.
• Click the + Add button to create a new environment (e.g., “Development”).
• Enter a Variable Name (e.g., API_KEY) and its corresponding Value (e.g., your_api_key_here).
• Click Save. To use the variable in a request, reference it with double curly braces (e.g., {{API_KEY}}).

3. Set API Key (Optional)

For API integrations requiring an API key:

• Open Postman and click your avatar in the top-left corner > Settings.
• Navigate to the General tab.
• In the API Key section, generate a new key or paste an existing one.
• Click Save to store the key securely.

By following these steps, you can successfully install and configure Postman on Ubuntu to streamline your API development workflow.
