const credentials = new AWS.EnvironmentCredentials('AWS');
let signer = new AWS.Signers.V4(this.request, 'es');
signer.addAuthorization(credentials, new Date());

尝试使用 AWS Lambda 在 elastisearch 中索引一些数据。

您应该有一个端点并已发起您的请求。您可以像下面一样执行此操作，并检查代码后粘贴的链接。

/* == Globals == */
var esDomain = {
    region: 'us-east-1',
    endpoint: 'my-domain-search-endpoint',
    index: 'myindex',
    doctype: 'mytype'
};
var endpoint = new AWS.Endpoint(esDomain.endpoint);
/*
 * The AWS credentials are picked up from the environment.
 * They belong to the IAM role assigned to the Lambda function.
 * Since the ES requests are signed using these credentials,
 * make sure to apply a policy that allows ES domain operations
 * to the role.
 */
var creds = new AWS.EnvironmentCredentials('AWS');

var req = new AWS.HttpRequest(endpoint);

    req.method = 'POST';
    req.path = path.join('/', esDomain.index, esDomain.doctype);
    req.region = esDomain.region;
    req.headers['presigned-expires'] = false;
    req.headers['Host'] = endpoint.host;
    req.body = doc;

    var signer = new AWS.Signers.V4(req , 'es');  // es: service code
    signer.addAuthorization(creds, new Date());
