CloudEnv
public class CloudEnv
A convenience class for obtaining environment variables that are mapped to JSON strings. It is mainly used for obtaining credentials for services so Swift applications can be written in a platform agnostic way.
There is a lot of information in the README
explaining how you can use cloudEnv
to access credentials for your services; more specific information is listed in the
API documentation below.
-
Name of the mappings file. This is set to
mappings.json
.Declaration
Swift
public static let mappingsFile = "mappings.json"
-
Port number the application can listen to.
Declaration
Swift
public var port: Int
-
URL that can be assigned to the application.
Declaration
Swift
public var url: String
-
Initialize an instance of
CloudEnv
.Usage Example:
let cloudEnv = CloudEnv()
The example below shows how to load configuration from both a
mappings.json
file and a Cloud Foundry credentials file when neither are in the default directory.let cloudEnv = CloudEnv(mappingsFilePath: "resources/mappings", cloudFoundryFile: "resources cfresources/cf.json")
Declaration
Swift
public init(mappingsFilePath: String? = nil, cloudFoundryFile: String? = nil)
Parameters
mappingsFilePath
Optional. The path to the
mappings.json
file; this path should be relative to the root folder of the Swift application.cloudFoundryFile
Optional. The path to a JSON file that contains values for Cloud Foundry environment variables (mainly used for testing); this path should be relative to the current working directory (which in most cases is the folder of the Swift application).
-
Returns the corresponding JSON dictionary value in a string.
If the service you intend to use in your Swift application is not one which we explicitly support, you can leverage the generic
getString(name: String)
method to get the corresponding credentials.Usage Example:
let cloudEnv = CloudEnv() if let credentials = cloudEnv.getString(name: "service1-credentials") { // You can now get the corresponding values from the credentials string. // The result string will follow JSON notation. }
Declaration
Swift
public func getString(name: String) -> String?
Parameters
name
The key to lookup the environment variable.
-
Returns the corresponding dictionary value.
If the service you intend to use in your Swift application is not one which we explicitly support, you can leverage the generic
getDictionary(name: String)
method to get the corresponding credentials.Usage Example:
let cloudEnv = CloudEnv() if let credentials: [String:Any] = cloudEnv.getDictionary(name: "service1-credentials") { // You can now get the corresponding values from the dictionary. }
Declaration
Swift
public func getDictionary(name: String) -> [String : Any]?
