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.
