Preface
Vue.js is a popular front-end development framework. As a developer who uses Vue to develop applications, you may encounter the problem of "Error: Request failed with status code 404". This error usually means that your application was trying to request some resource from the server (such as an API endpoint or an image) and was unable to find the resource. This article will help you understand the cause of this error and provide some solutions to fix it.
Error reason
When you request some resources from the Vue application to the server, and the server cannot find the requested resources, the "Error: Request failed with status code 404" error occurs. This may be caused by the following reasons:
1. Server-side configuration error: The server may not have the routes or endpoints configured correctly to handle the request. This may cause the server to be unable to find the resource requested by the application.
2. Application-side configuration error: Another possible reason is that the application does not configure the request correctly, such as the requested URL or request parameters are incorrect.
3. The resource does not exist: The most common problem is that the requested resource does not exist. This may be due to the resource being deleted on the server side or incorrectly named. This could also be due to a request URL change or resource movement.
Solution
1. Check the server-side configuration
If the "Error: Request failed with status code 404" error occurs, you should first check the server-side configuration. Ensure that the server's routes and endpoints are configured correctly and that resources are found correctly when requested by the application.
2. Check the application-side configuration
Another possible problem is an application-side configuration error. Check that all API calls in your Vue application have the correct URL and request parameters. Make sure you set up your Vue application's routes and endpoints correctly.
3. Check if the resource exists
If you still can't solve the problem after checking the server and application configuration, you may need to check if the requested resource exists. Check if the resource has been deleted or renamed from the server side. Make sure you name the requested URL correctly and check that the resource is in the correct location. If the resource has moved, the API calls in the Vue application need to be updated and point to the new location.
4. Handling Errors
When you encounter the error "Error: Request failed with status code 404", you should handle the error in time. In Vue.js, you can use try-catch blocks to catch API errors and issue an appropriate response to the user. For example, you can display a message to the user that the requested resource does not exist, or you can redirect to another URL or page.
Conclusion
"Error: Request failed with status code 404" error is a common problem in Vue application development. This error usually means that the requested resource cannot be found in the server. You can resolve this error by checking the configuration of your server and application to ensure that the requested URL is named correctly. If the problem persists after these steps, you can handle the error and display an appropriate response to the user.
