Not able to get posts from 'tryghost' with Axios error

The issue of not being able to get posts from 'tryghost' using Axios can arise due to several potential reasons, including API endpoint issues, incorrect headers, or Axios configuration errors. Here's a detailed guide on how to troubleshoot and fix this issue, complete with code examples.

1. Check Your API Endpoint

Ensure you're using the correct API endpoint. The Ghost Content API usually follows a pattern like this:

Example


https://<your-ghost-site>/ghost/api/content/posts/?key=<your-api-key>

Make sure you have:

The correct URL for your Ghost installation.
The correct API key, which you can find in your Ghost Admin settings under Integrations.

2. Axios Configuration

Axios might fail due to improper configuration. Ensure you're making a proper GET request with the right headers and parameters. Here’s an example:

Example Code:

Example


const axios = require('axios');

const apiKey = 'your_api_key_here';  // Replace with your actual API key
const baseUrl = 'https://your-ghost-site.com/ghost/api/content/posts/';

axios.get(`${baseUrl}?key=${apiKey}`)
  .then(response => {
    console.log(response.data.posts);
  })
  .catch(error => {
    if (error.response) {
      // The request was made and the server responded with a status code outside of 2xx
      console.log('Error Response:', error.response.data);
      console.log('Status Code:', error.response.status);
    } else if (error.request) {
      // The request was made but no response was received
      console.log('No response received:', error.request);
    } else {
      // Something else happened during the request setup
      console.log('Axios Error:', error.message);
    }
  });

3. Handle CORS Errors

If your Ghost API is on a different domain than your frontend (like a React or Vue app), you may face Cross-Origin Resource Sharing (CORS) issues. This can result in Axios failing to make the request. You can resolve CORS issues by:

Configuring your Ghost server to allow cross-origin requests.
Using a proxy server.

In your Ghost configuration (config.production.json), ensure CORS is enabled:

Example


{
  "url": "https://your-ghost-site.com",
  "server": {
    "port": 2368,
    "host": "127.0.0.1"
  },
  "paths": {
    "contentPath": "content/"
  },
  "cors": true
}

Alternatively, if you’re using Node.js, you can also set up a CORS proxy or use middleware.

4. Network Issues

Axios can run into issues related to network requests (timeouts, network failure, etc.). Setting a longer timeout may help if your Ghost instance takes longer to respond:

Example


axios.get(`${baseUrl}?key=${apiKey}`, { timeout: 10000 })  // 10-second timeout
  .then(response => {
    console.log(response.data.posts);
  })
  .catch(error => {
    console.error('Network error:', error.message);
  });

5. Handling Rate Limits

Ghost may apply rate limits on the API depending on the hosting plan or configuration. If you're hitting rate limits, your request will be rejected with a 429 status code. You can check for rate limits in the response headers:

Example


axios.get(`${baseUrl}?key=${apiKey}`)
  .then(response => {
    console.log(response.data.posts);
  })
  .catch(error => {
    if (error.response && error.response.status === 429) {
      console.log('Rate limit exceeded. Try again later.');
    } else {
      console.error('API Error:', error.message);
    }
  });

6. Check for API Authentication Issues

Ensure that your API key is valid and has the correct permissions to access posts. If the API key is incorrect or does not have the correct permissions, the request will fail with a 401 (Unauthorized) or 403 (Forbidden) error.

Common Errors and Solutions

401 Unauthorized: This error occurs if your API key is missing or incorrect. Double-check that you’re passing the correct key in the URL.
404 Not Found: Ensure your Ghost Content API endpoint is correct. Verify the URL and make sure the posts endpoint is available.
429 Too Many Requests: You've hit a rate limit. Implement retry logic or reduce the number of requests.
CORS Issues: Ensure your Ghost server is properly configured to allow requests from your frontend's domain, or use a proxy.

Conclusion

By following these steps, you should be able to resolve most issues with fetching posts from Ghost using Axios. Ensure that your API key is correct, the API endpoint is properly configured, and CORS and network issues are addressed.
