This can be extended by passing it an ArrayRef of allowed \s-1HTTP\s0 methods. .PP The route handler gets the Dancer \f(CW$self\fR object passed in, just like any other Dancer2 route handler. You can use this to inspect the request data. .PP .Vb 2 \& ajax \*(Aq/check_for_update\*(Aq => sub { \& my $self = shift; \& \& my $method = $self\->app\->request\->method; \& # ... \& } .Ve .SH "CONFIGURATION" .IX Header "CONFIGURATION" By default the plugin will use a content-type of 'text/xml', but this can be overridden with the plugin setting \f(CW\*(C`content_type\*(C'\fR. .PP Here is an example to use \s-1JSON:\s0 .PP .Vb 3 \& plugins: \& Ajax: \& content_type: \*(Aqapplication/json\*(Aq .Ve .SH "AUTHOR" .IX Header "AUTHOR" Dancer Core Developers .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2016 by Alexis Sukrieh. .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
