NAME WebService::BaseClientRole - [DEPRECATED] A base role for quickly and easily creating web service clients VERSION version 0.0008 SYNOPSIS This module has been DEPRECATED in favor of WebService::Client. Please consider using that instead. { package WebService::Foo; use Moo; with 'WebService::BaseClientRole'; has auth_token => ( is => 'ro', required => 1 ); has '+base_url' => ( default => 'https://foo.com/v1' ); sub BUILD { my ($self) = @_; $self->ua->default_header('X-Auth-Token' => $self->auth_token); # or if the web service uses http basic/digest authentication: # $self->ua->credentials( ... ); } sub get_widgets { my ($self) = @_; return $self->get("/widgets"); } sub get_widget { my ($self, $id) = @_; return $self->get("/widgets/$id"); } sub create_widget { my ($self, $widget_data) = @_; return $self->post("/widgets", $widget_data); } } my $client = WebService::Foo->new( auth_token => 'abc', logger => Log::Tiny->new('/tmp/foo.log'), # optional timeout => 10, # optional, defaults to 10 retries => 0, # optional, defaults to 0 ); $client->create_widget({ color => 'blue' }); DESCRIPTION This module has been DEPRECATED in favor of WebService::Client. Please consider using that instead. This module is a base role for quickly and easily creating web service clients. Every time I created a web service client, I noticed that I kept rewriting the same boilerplate code independent of the web service. This module does the boring boilerplate for you so you can just focus on the fun part - writing the web service specific code. It is important to note that this only supports JSON based web services. If your web service does not support JSON, then I am sorry. METHODS These are the methods this role composes into your class. The HTTP methods (get, post, put, and delete) will return the deserialized response data, assuming the response body contained any data. This will usually be a hashref. If the web service responds with a failure, then the corresponding HTTP response object is thrown as an exception. This exception is simply an HTTP::Response object that can be stringified. HTTP responses with a status code of 404 or 410 will not result in an exception. Instead, the corresponding methods will simply return undef. The reasoning behind this is that GET'ing a resource that does not exist does not warrant an exception. get $client->get('/foo') Makes an HTTP POST request. post $client->post('/foo', { some => 'data' }) Makes an HTTP POST request. put $client->put('/foo', { some => 'data' }) Makes an HTTP PUT request. delete $client->delete('/foo') Makes an HTTP DELETE request. req my $req = HTTP::Request->new(...); $client->req($req); This is called internally by the above HTTP methods. You will usually not need to call this explicitly. It is exposed as part of the public interface in case you may want to add a method modifier to it. Here is a contrived example: around req => sub { my ($orig, $self, $req) = @_; $req->authorization_basic($self->login, $self->password); return $self->$orig($req, @rest); }; log Logs a message using the provided logger.
