Shield Advanced
This is the Shield Advanced API Reference. This guide is for developers who need detailed information about the Shield Advanced API actions, data types, and errors. For detailed information about WAF and Shield Advanced features and an overview of how to use the WAF and Shield Advanced APIs, see the WAF and Shield Developer Guide.
To install this package, simply type add or install @aws-sdk/client-shield using your favorite package manager:
npm install @aws-sdk/client-shieldyarn add @aws-sdk/client-shieldpnpm add @aws-sdk/client-shieldThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the ShieldClient and
the commands you need, for example ListAttacksCommand:
// ES5 example
const { ShieldClient, ListAttacksCommand } = require("@aws-sdk/client-shield");
// ES6+ example
import { ShieldClient, ListAttacksCommand } from "@aws-sdk/client-shield";
To send a request, you:
send operation on client with command object as input.destroy() to close open connections.// a client can be shared by different commands.
const client = new ShieldClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListAttacksCommand(params);
We recommend using await operator to wait for the promise returned by send operation as follows:
// async/await.
try {
const data = await client.send(command);
// process data.
} catch (error) {
// error handling.
} finally {
// finally.
}
Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.
You can also use Promise chaining to execute send operation.
client.send(command).then(
(data) => {
// process data.
},
(error) => {
// error handling.
}
);
Promises can also be called using .catch() and .finally() as follows:
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});
We do not recommend using callbacks because of callback hell, but they are supported by the send operation.
// callbacks.
client.send(command, (err, data) => {
// process err and data.
});
The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript
import * as AWS from "@aws-sdk/client-shield";
const client = new AWS.Shield({ region: "REGION" });
// async/await.
try {
const data = await client.listAttacks(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listAttacks(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listAttacks(params, (err, data) => {
// process err and data.
});
When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).
try {
const data = await client.send(command);
// process data.
} catch (error) {
const { requestId, cfId, extendedRequestId } = error.$metadata;
console.log({ requestId, cfId, extendedRequestId });
/**
* The keys within exceptions are also parsed.
* You can access them by specifying exception names:
* if (error.name === 'SomeServiceException') {
* const value = error.specialKeyInException;
* }
*/
}
