useRequest has caught the exception, if you need to handle the exception yourself, you can set options.throwOnError to true.-Go服务器开发

The message you provided is related to the use of a custom hook or library for making requests in a JavaScript/React application, likely from a library such as react-query or similar. It indicates that an error has occurred during a data fetching operation, and it suggests an option to handle this error manually.

Here’s how you can handle the exception using the options.throwOnError option:

Example

Assuming you’re using a library like react-query, here’s how you could set it up:

import { useQuery } from 'react-query';

const fetchData = async () => {
  const response = await fetch('https://api.example.com/data');
  if (!response.ok) {
    throw new Error('Network response was not ok');
  }
  return response.json();
};

const MyComponent = () => {
  const { data, error, isLoading } = useQuery('dataKey', fetchData, {
    throwOnError: true // This will allow you to catch errors yourself
  });

  if (isLoading) {
    return <div>Loading...</div>;
  }

  if (error) {
    console.error(error);
    return <div>Error: {error.message}</div>; // Handle the error here
  }

  return (
    <div>
      {/* Render your data here */}
      {JSON.stringify(data)}
    </div>
  );
};

Explanation

fetchData Function: This function fetches data from an API and throws an error if the response is not OK.
useQuery Hook: The useQuery hook is used to execute the fetchData function. The option throwOnError: true allows exceptions thrown within the query function to propagate so that they can be caught in your component.
Handling Errors: In the component, you check for loading states and potential errors. If there is an error, it will be logged and displayed to the user.

By configuring your request options this way, you gain more control over how errors are handled in your application.
