Managing exceptions from Binance API with Ethereum
As a developer, exceptions are crucial to ensuring smooth interactions with external API. In this article, we will examine how to handle the exception induced by the Binance API API in relation to its integration Ethereum.
what’s going under the hood
When you call the endpoint of etherscan.com at the Binance API interface, Json will return the Json containing different fields and data. During this process, however, there may sometimes occur errors, leading to the ejection of exceptions. These exceptions are usually a “error” type, which is not an instance of any particular class. If you are trying to access or use these features, as if they were objects (such as clianterror" in your example), it leads to "Typeerror".
solution to solve exceptions
To handle this exception and provide meaningful feedback, we can create our own feature that checks the type of returned object before attempting to access his attribute.
Javascript
Thethereumemecept of the Handle Function (ERROR) {
IF (Typeof Error === ‘string’ || Typeof Error ==== ‘Number’) {
Console.log (API ERROR: $ {error});
return;
}
// Check that an error is an instance of an error
IF (Instanceof Error Error && eror.Message.includes (‘Object has no attribute’)) {
Console.log (“Details of the Error:”);
Console.error (error.message);
Throw out a new error (“Failed to get API data Ethereum API. Check API Binance documentation”);
} Else {
// default case for unknown or unauthorized errors
Throw out a new error (unknown error: $ {error});
}
}
// Example of using Handlethereumememection when successful call API

Proven procedures
When handling exceptions in your code:
1.
- Protocol errors Effectively : Use logging mechanisms such as console logs or file -based logging to provide meaningful information about the mistakes you encounter.
- Throw your own exceptions : If the error cannot be solved by your own exception, throw it away directly to inform the caller problem.
By implementing this solution and adhering to proven exception procedures, you can improve the robustness, maintenance of your code and user experience with external API, such as the integration of Binance Ethereum, such as the integration of Binance Ethereum.
