GcpConnectionParams

Extends: ConfigParams

Description

Contains connection parameters to authenticate against Google Functions and connect to specific Google Function.

The class is able to compose and parse Google Function connection parameters.

In addition to standard parameters CredentialParams may contain any number of custom parameters

Configuration parameters

• connections:
  • uri: full connection uri with specific app and function name
  • protocol: connection protocol
  • project_id: is your Google Cloud Platform project ID
  • region: is the region where your function is deployed
  • function_name: is the name of the HTTP function you deployed
• credentials:
  • auth_token: Google-generated ID token or null if using custom auth

Constructors

Creates an new instance of the connection parameters.

public constructor(values: any = null)

• values: any - (optional) an object to be converted into key-value pairs to initialize this connection.

getUri

Gets the Google Platform service uri.

public getUri(): string

• returns: string - the Google function uri.

getProtocol

Gets the Google function connection protocol.

public getProtocol(): string

• returns: string - the Google function connection protocol.

getProjectId

Gets the Google Cloud Platform project ID.

public getProjectId(): string

• returns: string - the project ID.

getRegion

public getRegion(): string

• returns: string - the region of deployed function.

setAuthToken

Sets an ID token with the request to authenticate themselves

public setAuthToken(value: string)

• value: string - a new ID token.

setFunction

Sets the Google function name.

public setFunction(value: string)

• value: string - a new Google function name.

setUri

Sets the Google Platform service uri.

public setUri(value: string)

• value: string - a new Google function uri.

setProtocol

Sets the Google function connection protocol.

public setProtocol(value: string)

• value: string - a new Google function connection protocol.

setProjectId

Sets the Google Cloud Platform project ID.

public setProjectId(value: string)

• value: string - a new project ID.

setRegion

Sets the region where your function is deployed.

public setRegion(value: string)

• returns: string - the region of deployed function

validate

Validates this connection parameters

public validate(context: IContext)

• context: IContext - (optional) a context to trace execution through a call chain.

Static methods

fromString

Creates a new GcpConnectionParams object filled with key-value pairs serialized as a string.

public static fromString(line: string): GcpConnectionParams

• line: string - a string with serialized key-value pairs as “key1=value1;key2=value2;…”
  Example: “Key1=123;Key2=ABC;Key3=2016-09-16T00:00:00.00Z”
• returns: GcpConnectionParams - a new GcpConnectionParams object.

fromConfig

Validates this connection parameters

public static fromConfig(config: ConfigParams): GcpConnectionParams

• config: ConfigParams - configuration parameters
• returns: GcpConnectionParams - the generated GcpConnectionParams object.

mergeConfigs

Retrieves GcpConnectionParams from multiple configuration parameters. The values are retrieves from “connection” and “credential” sections.

public static mergeConfigs(…configs: ConfigParams[]): GcpConnectionParams

• config: string - a list with configuration parameters
• returns: GcpConnectionParams - the generated GcpConnectionParams object.

Examples

let connection = GcpConnectionParams.fromTuples(
    'connection.uri', 'http://east-my_test_project.cloudfunctions.net/myfunction',
    'connection.protocol', 'http',
    'connection.region', 'east',
    'connection.function_name', 'myfunction',
    'credential.project_id', 'my_test_project',
    'credential.auth_token', '1234',
);

const uri = connection.getUri();             // Result: 'http://east-my_test_project.cloudfunctions.net/myfunction'
const region = connection.getRegion();               // Result: 'east'
const protocol = connection.getProtocol();           // Result: 'http'
const functionName = connection.getFunction();   // Result: 'myfunction'
const projectId = connection.getProjectId();         // Result: 'my_test_project'
const authToken = connection.getAuthToken();         // Result: '123'
