To obtain the log category while executing Azure Functions offline, you can use the logging feature provided by Azure Functions. Here are the steps:
Install the Azure Functions Core Tools: If you haven't installed the Azure Functions Core Tools on your local machine, you can download and install them from the Azure Functions Core Tools page.
Create a new Azure Function: Choose your language and template to create a new Azure Function in the local dev environment.
Add logging statements: Add logging statements to your Azure Function code to log any specific log category, using the logging framework of your language.
Start the Azure Function: Start the Azure Function in the local dev environment using the Azure Functions Core Tools.
View the log output: View the log output in the console that displays the category of the logs.
For instance, in Node.js, you can use the following function to log messages with different levels:
module.exports = function (context, req) {
context.log('This is a log message'); // logging level: information
context.log.warn('This is a warning message'); // logging level: warning
context.log.error('This is an error message'); // logging level: error
context.log.verbose('This is a verbose message'); // logging level: verbose
context.log.debug('This is a debug message'); // logging level: debug
context.log.silly('This is a silly message'); // logging level: silly
context.res = {
status: 200,
body: "Hello World!"
};
context.done();
};
In the output window, you can observe the category of the log message, such as "information", "warning", "error", "verbose", "debug", or "silly".
