Simplify the interface for most cowboy_req functions. They all return a single value except the four body reading functions. The reply functions now only return a Req value. Access functions do not return a Req anymore. Functions that used to cache results do not have a cache anymore. The interface for accessing query string and cookies has therefore been changed. There are now three query string functions: qs/1 provides access to the raw query string value; parse_qs/1 returns the query string as a list of key/values; match_qs/2 returns a map containing the values requested in the second argument, after applying constraints and default value. Similarly, there are two cookie functions: parse_cookies/1 and match_cookies/2. More match functions will be added in future commits. None of the functions return an error tuple anymore. It either works or crashes. Cowboy will attempt to provide an appropriate status code in the response of crashed handlers. As a result, the content decode function has its return value changed to a simple binary, and the body reading functions only return on success. |

REST pastebin example
To try this example, you need GNU make and git in your PATH.
To build the example, run the following command:
$ make
To start the release in the foreground:
$ ./_rel/rest_pastebin_example/bin/rest_pastebin_example console
Then point your browser at http://localhost:8080.
Usage
To upload something to the paste application, you can use curl:
$ <command> | curl -i --data-urlencode paste@- localhost:8080
Or, to upload the file my_file:
curl -i --data-urlencode paste@my_file localhost:8080
The URL of your data will be in the location header. Alternately, you can visit http://localhost:8080 with your favorite web browser and submit your paste via the form.
Code that has been pasted can be highlighted with ?lang= option if
you have highlight
installed (although pygments or any other should work just fine).
This will show the contents of the HTML file:
curl -i --data-urlencode paste@priv/index.html localhost:8080
curl <url from location header>
If your terminal supports color sequences and highlight is installed,
the following command will show the same contents but with HTML syntax
highlighting.
curl <url from location header>?lang=html
If you open the same URL in your web browser and your web browser tells Cowboy that it prefers HTML files, you will see the file highlighted with special HTML markup and CSS. Firefox is known to work.
