Error: Http Response is Not OK. Response Status Code is 404: Troubleshooting the Issue
Introduction
When working with APIs, it's not uncommon to encounter errors that can be frustrating to resolve. One such error is the "Http response is not OK. Response status code is 404" message, which indicates that the requested resource was not found. In this article, we'll delve into the possible causes of this error and provide step-by-step solutions to help you troubleshoot and resolve the issue.
Understanding the Error
The "Http response is not OK. Response status code is 404" error is a standard HTTP status code that indicates the requested resource could not be found on the server. This error can occur due to various reasons, including:
- Incorrect URL: The URL being used in your Python script might be incorrect or outdated.
- Resource Not Found: The resource you're trying to access might not exist on the server.
- Server-Side Issues: The server might be experiencing technical difficulties or maintenance, resulting in the resource not being available.
Analyzing the Issue
In your case, you've checked the URL being used in query.py, and it returns a "Not Found" error. This suggests that the issue might be related to the URL or the resource being requested.
Step 1: Verify the URL
Double-check the URL being used in your Python script to ensure it's correct and up-to-date. You can use tools like curl or Postman to test the URL and see if it returns a 404 error.
Step 2: Check the Resource
Verify that the resource you're trying to access exists on the server. You can use the server's documentation or contact the server administrator to confirm the existence of the resource.
Step 3: Inspect the API Documentation
Review the API documentation to ensure you're using the correct endpoint and parameters. The documentation might provide additional information on how to access the resource or troubleshoot common issues.
Step 4: Use a Debugger or Logging
Use a debugger or logging statements to inspect the values of variables and the execution flow of your Python script. This can help you identify any issues with the URL or resource being requested.
Step 5: Contact the Server Administrator
If none of the above steps resolve the issue, contact the server administrator or API support team to report the error and seek assistance. They might be able to provide additional information or help you troubleshoot the issue.
Example Use Case
Here's an example use case that demonstrates how to troubleshoot the "Http response is not OK. Response status code is 404" error:
import requests
def query_plsdb(url):
try:
response = requests.get(url)
response.raise_for_status()
return response.json()
except requests.exceptions.HTTPError as errh:
print(f"Http Error: {errh}")
except requests.exceptions.ConnectionError as errc:
print(f"Error Connecting: {errc}")
except requests.exceptions.Timeout as errt:
print(f"Timeout Error: {errt}")
except requests.exceptions.RequestException as err:
print(f"Something went wrong: {err}")
url = "https://example.com/plsdb"
result = query_plsdb(url)
if result:
print(result)
else:
print("Error: Http response is not OK. Response status code is 404.")
In this example, we define a function query_plsdb
that takes a URL as input and attempts to retrieve the response using the requests
library. We then handle any exceptions that might occur, including the "Http response is not OK. Response status code is 404" error.
Conclusion
The "Http response is not OK. Response status code is 404" error can be frustrating to resolve, but by following the steps outlined in this article, you should be able to troubleshoot and resolve the issue. Remember to verify the URL, check the resource, inspect the API documentation, use a debugger or logging, and contact the server administrator if necessary. With patience and persistence, you should be able to resolve the issue and continue working with your Python script.
