How to check if the server causes Vue Axios "Network Error"

When using Axios to initiate HTTP requests in a Vue.js application, it can be frustrating to encounter a "Network Error" error. This error usually means that the server is unavailable or the response is incorrect. Here is how to check if the server is an error cause:

1. Check the server connection

• Confirm that the target server is up and running normally.
• Use tools such as curl or Postman to manually send requests to check server responses.

2. Check the server log

• Check the server log for any records about request errors.
• The log may contain detailed information about server-side errors or configuration issues.

3. Check CORS policy

• Make sure the server is correctly configured with CORS (cross-domain resource sharing) policies.
• The CORS policy restricts requests from different domains, so missing or misconfigured policies can cause errors.

4. Check the server timeout

• Check the server request timeout setting.
• Axios may have its own timeout settings, but the server may also enforce its own timeout.

5. Check the response code

• Check the server response code.
• The 4xx and 5xx error codes usually indicate server-side errors.

6. Check the response header

• Check the server response header for any exceptions.
• The header may contain additional information about server errors or configuration issues.

7. Check the proxy settings

• If you are using a proxy to connect to the server, make sure the proxy is configured correctly.
• Misconfigured proxy may interfere with the connection or cause an error.

8. Check the firewall

• Check the server firewall to ensure that requests from the application are allowed.
• Firewall rules may be misconfigured, preventing requests from reaching the server.

By following these steps, you can determine whether the server is the potential cause of the Vue Axios "Network Error" error. Resolving any server-side issues or configuration errors will help resolve the error and allow the application to communicate with the server properly.
