使用自定义OAuth提供商获取Token后，如何初始化sn-client-js的Repository？

Hey there! I’ve worked with sn-client-js and custom OAuth setups before, so let me break down exactly how to pass your tokens when initializing the Repository.

First, you’ll need to wrap your access and refresh tokens into a config object that sn-client-js understands. This is where you’ll also handle things like token type and automatic refresh logic (if you want it).

Here’s a sample config tailored for custom OAuth:

// Replace these with your actual token values
const authConfig = {
  accessToken: 'your-actual-access-token',
  refreshToken: 'your-actual-refresh-token',
  tokenType: 'Bearer', // Most OAuth providers use this—adjust if yours differs
  // Optional: Add a callback to handle token refresh events
  onTokenRefresh: async (updatedTokens) => {
    // Store the new tokens somewhere secure (e.g., localStorage, your backend)
    console.log('Tokens refreshed successfully:', updatedTokens);
    // Example: localStorage.setItem('authTokens', JSON.stringify(updatedTokens));
  }
};

Next, pass this authConfig directly into the Repository constructor as part of the main configuration object. Don’t forget to include any other required settings like your API base URL if it’s not the default.

import { Repository } from 'sn-client-js';

// Initialize the repository with your auth config
const myRepository = new Repository({
  baseUrl: 'https://your-api-endpoint.com', // Replace with your actual API URL
  auth: authConfig
});

To confirm everything works, try fetching some user content with the initialized repository:

async function fetchUserContent() {
  try {
    const content = await myRepository.get('/user/your-content-path');
    console.log('Fetched user content:', content);
  } catch (error) {
    console.error('Error accessing content:', error);
    // Check if the error is token-related (e.g., expired) to debug
  }
}

// Run the test
fetchUserContent();

• Token Security: Never hardcode tokens in your frontend code. Fetch them from a secure source (like your backend after login) or retrieve them from encrypted storage (e.g., sessionStorage).
• Token Type: Double-check your OAuth provider’s token type—if it’s not Bearer, update the tokenType field in authConfig to match.
• Refresh Logic: The onTokenRefresh callback is optional but highly recommended. It lets you automatically update stored tokens when the access token expires, so your users don’t get logged out unexpectedly.
