Internet

The InternetUD component allows making real-world HTTP(s) requests. In order to be able to send HTTP(s) requests, make sure the current computer is connected to a WAN Router either directly via Network Cable or indirectly through Network Routers.

Security

By default, requests to local IP addresses are blocked (e.g. http://127.0.0.1). Domains are not filtered. You can allow access to local IPs by disabling the filtering in the config file.

Disabling this filtering will allow ingame computers to access webservices on the server's local machine (if any). This could pose a security threat if any of those local webservices assume local traffic to be trustworthy. Be careful!

If you wish, HTTP(s) functionality can also be disabled entirely in the config file. This completely removes the ability to make any kind of HTTP(s) requests.

API

InternetUD component properties

Name	Type	Read/Write	Description
isHttpEnabled	bool	READ	Returns whether HTTP(s) is enabled at all. True by default, but can be changed in the server's config. Required to be true in order to use any methods.
isConnectedToWan	bool	READ	Returns whether the current computer can reach a WAN router via the network. Required to be true in order to use any methods.

InternetUD component methods

Name	Returns	Description
:sendHttpRequest(url:string[, method:string[, postData:string[, headers:table]]])	HttpResponseUD	Asynchronously sends an HTTP(s) request to the given URL with the given request method (e.g. GET, POST, etc.). If the request method is set to something supporting a post body, you may provide one as a string in postData. Otherwise postData must be set to "". Headers may be provided as a table consisting of string keys and string values. The request method TRACE is not allowed for security reasons.

Handling responses

Upon making an HTTP(s) request you are provided with an HttpResponseUD object offering the following functionality.

HttpResponseUD properties

Name	Type	Read/Write	Description
responseAvailable	bool	READ	Returns whether this HTTP(s) request has been completed and therefore a response is available.

HttpResponseUD methods

Name	Returns	Description
:waitForCompletion()	void	Blocks until responseAvailable is true. All other functions implicitly call this prior to executing and thus show the same behaviour.
:getStatusCode()	int	Returns the HTTP status code of the response.
:waitForCompletion()	void	Blocks until responseAvailable is true. All other functions implicitly call this and thus show the same behaviour.
:waitForCompletion()	void	Blocks until responseAvailable is true. All other functions implicitly call this and thus show the same behaviour.
