HTTP Ext is an extension for SkySpark v3.0.13+ that provides Axon functions for making HTTP requests and calling REST APIs.
HTTP Ext has explicit functions for making
DELETE requests over
https allowing you to modify all aspects of the HTTP request, including headers, body content, and connection settings.
There are even functions for uploading files and posting forms! The rich HTTP response object then allows you to inspect status codes, status messages, headers, and body content.
HTTP Ext is free to download and evaluate but a licence must be purchased for production use. See Licensing for details.
Axon methods may be categorised in to the following:
There is one generic, general purpose function for making HTTP requests:
It takes a
Dict of (mostly optional) request parameters and returns a
Dict of response parameters, and is capable of calling most REST APIs.
Convenience functions make simple HTTP requests, optionally taking HTTP request headers and / or a body, and return the HTTP response body as a string. An Err is thrown if the HTTP response code matches 4xx or 5xx.
Because it is often useful to inspect response details, the response
Dict (the same as what would have been returned from
afHttpSendReq()) is available by calling:
You may call this function after calling any of the convenience functions.
The following specialised functions also return the HTTP response body as a string:
Like the convenience functions, you may also call
afHttpLastRes() after calling a specialised function to return a
Dict of the last HTTP response.
Other helpful functions:
Should any of the HTTP functions throw an
javax.net.ssl.SSLHandshakeException, then that signifies a problem with the underlying Java platform and not the Axon functions.
Note that SSL is not a type of encryption, it's an ever growing suite of standards and technology. Meaning web clients (in our case Java) has to continually grow to support it all.
Make sure Java supports the required server cipher by inspecting the server's SSL certificate in a browser, or by visiting SSL Labs. Then visit Oracle's Java Security Providers to ensure the cipher is supported. See StackOverflow's Problems connecting to HTTPS/SSL with Java client for details.
Note that strong encryption ciphers are often disabled in Java by default. To enable them, you may need to install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.
HTTP Ext is a Commercial product and requires a licence to be purchased in order to run unhindered.
Licences for HTTP Ext are tied to an SkySpark organisation. This means it is valid for and will work on, any SkySpark installation within your organisation, but will not work on SkySpark installations for other organisations. You will need to enter your SkySpark organisation ID when purchasing, see Where is my SkyArc Organization ID? for details.
Purchased licences are available from the My Licences page and should be downloaded to the
/var/lic/ directory of your SkySpark installation.
Minor updates to HTTP Ext may be provided free of charge, but major updates will require a new licence to be purchased.
Although free to download, HTTP Ext enters into an Evaluation Mode if it does not find a valid licence; whereby its Axon functions may only be invoked 50 times.
