Parsing User-Agent strings with a web service
by Sven Van Caekenberghe Feb. 1, 2016

Feb. 1, 2016

I want to share a snippet of code. In HTTP, a client identifies itself using the User-Agent header. That string is long and cryptic. To make sense of it you have to parse it. There are web services that can do this. Here is how you can invoke one of them. ZnClient new http; host: 'useragentstring.com'; queryAt: 'uas' put: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_3) AppleWebKit/601.4.4 (KHTML, like Gecko) Version/9.0.3 Safari/601.4.4'; queryAt: 'getJSON' put: 'all'; contentReader: [ :entity | NeoJSONReader fromString: entity contents ]; get. Since STON parsing is backward compatible with JSON, you can use that as well. ZnClient new http; host: 'useragentstring.com'; queryAt: 'uas' put: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_3) AppleWebKit/601.4.4 (KHTML, like Gecko) Version/9.0.3 Safari/601.4.4'; queryAt: 'getJSON' put: 'all'; contentReader: [ :entity | STON fromString: entity contents ]; get. You will get back a nice dictionary with much more sensible key/value pairs. Note that this is a public service. I think it would be polite and more efficient if you put a cache in front of it, like LRUCache. Sven
