Node.js UnhandledPromiseRejectionWarning: connect ECONNREFUSED ::1:80 - 解决方法

This warning is indicating that there was an unhandled promise rejection in your code. The error message suggests that there was an issue connecting to the local server at "::1:80".\n\nTo resolve this issue, you should handle the promise rejection by adding a ".catch()" block to your async function. This will allow you to handle any errors that occur during the promise execution. Alternatively, you can also use the "--unhandled-rejections=strict" flag when running your code to terminate the process on unhandled promise rejections.\n\nHere's an example of how you can handle the promise rejection:\n\njavascript\nasync function myFunction() {\n try {\n // your code that could potentially throw a promise rejection\n } catch (error) {\n // handle the error\n }\n}\n\nmyFunction().catch((error) => {\n // handle the unhandled promise rejection here\n});\n\n\nBy adding a ".catch()" block to your async function and using a ".catch()" on the function call, you can handle and log any errors that occur during the promise execution. This will prevent the warning and ensure that the promise rejection is properly handled.
