import ballerina/config;
import ballerina/io;
import wso2/twilio;public function main(string... args) {endpoint twilio:Client twilioClient {accountSId:config:getAsString("ACCOUNT_SID"),authToken:config:getAsString("AUTH_TOKEN"),xAuthyKey:config:getAsString("AUTHY_API_KEY")};var details = twilioClient->getAccountDetails();match details {twilio:Account account => io:println(account);twilio:TwilioError twilioError => io:println(twilioError);}
}

我们可以使用ballerina init 创建

endpoint：
public type TwilioClient object {// 配置参数public TwilioConfiguration twilioConfig;public TwilioConnector twilioConnector = new;// init  函数public function init(TwilioConfiguration config);documentation { Initialize Twilio endpointR{{}} The Twilio connector object}// getCallerActions 函数public function getCallerActions() returns TwilioConnector;
};
配置说明：
public type TwilioConfiguration record {http:ClientEndpointConfig clientConfig;
};

public type TwilioConnector object {public string accountSId;public http:Client client;public function getAccountDetails() returns Account|error;
};

public type Account record {string sid;string name;string status;string ^"type";string createdDate;string updatedDate;
};// Constants
@final string BASE_URL = "https://api.twilio.com/2010-04-01";
@final string ACCOUNTS_API = "/Accounts/";
@final string RESPONSE_TYPE_JSON = ".json";
@final string EMPTY_STRING = "";

function TwilioClient::getCallerActions() returns TwilioConnector {return self.twilioConnector;
}
function TwilioClient::init(TwilioConfiguration config) {config.clientConfig.url = BASE_URL;string username;string password;var usernameOrEmpty = config.clientConfig.auth.username;match usernameOrEmpty {string usernameString => username = usernameString;() => {error err = { message: "Username cannot be empty" };throw err;}}var passwordOrEmpty = config.clientConfig.auth.password;match passwordOrEmpty {string passwordString => password = passwordString;() => {error err = { message: "Password cannot be empty" };throw err;}}self.twilioConnector.accountSId = username;self.twilioConnector.client.init(config.clientConfig);
}

function TwilioConnector::getAccountDetails() returns Account|error {endpoint http:Client httpClient = self.client;string requestPath = ACCOUNTS_API + self.accountSId + RESPONSE_TYPE_JSON;var response = httpClient->get(requestPath);json jsonResponse = check parseResponseToJson(response);return mapJsonToAccount(jsonResponse);
}
