LineClient
- Usage
- Methods
- Debug Tips
- Test
Usage
Get the LineClient
instance using the getClient
function:
const { getClient } = require('bottender');
// This `client` variable is a `LineClient` instance
const client = getClient('line');
await client.pushText(USER_ID, 'Hello!');
Or, get the LineClient
instance from the context
:
async function MyAction(context) {
if (context.platform === 'line') {
// `context.client` is a `LineClient` instance
await context.client.pushText(USER_ID, 'Hello!');
}
}
Error Handling
LineClient
uses axios as HTTP client. We use axios-error package to wrap API error instances for better formatting error messages. Calling console.log
with the error instance returns the formatted message. If you'd like to get the axios request
, response
, or config
, you can still get them via those keys on the error instance.
client.replyText(token, text).catch((error) => {
console.log(error); // the formatted error message
console.log(error.stack); // stack trace of the error
console.log(error.config); // axios request config
console.log(error.request); // axios HTTP request
console.log(error.response); // axios HTTP response
});
Methods
All methods return a Promise.
