60 An easy to use SOAP/1.1 daemon for POE-enabled programs
61
63 This module makes serving SOAP/1.1 requests a breeze in POE.
64 The hardest thing to understand in this module is the SOAP Body. That's
66 it!
67 The standard way to use this module is to do this:
69 use POE;
71 use POE::Component::Server::SOAP;
72 POE::Component::Server::SOAP->new( ... );
74 POE::Session->create( ... );
76 POE::Kernel->run();
78 POE::Component::Server::SOAP is a bolt-on component that can publish
80 event handlers via SOAP over HTTP. Currently, this module only
81 supports SOAP/1.1 requests, work will be done in the future to support
82 SOAP/1.2 requests. The HTTP server is done via
83 POE::Component::Server::SimpleHTTP.
84 Starting Server::SOAP
86 To start Server::SOAP, just call it's new method:
87 POE::Component::Server::SOAP->new(
89 'ALIAS' => 'MySOAP',
90 'ADDRESS' => '192.168.1.1',
91 'PORT' => 11111,
92 'HOSTNAME' => 'MySite.com',
93 'HEADERS' => {},
94 );
95 This method will die on error or return success.
97 This constructor accepts only 7 options.
99 "ALIAS"
101 This will set the alias Server::SOAP uses in the POE Kernel. This
102 will default to "SOAPServer"
103 "ADDRESS"
105 This value will be passed to POE::Component::Server::SimpleHTTP to
106 bind to.
107 Examples: ADDRESS => 0 # Bind to all addresses +
109 localhost ADDRESS => 'localhost' # Bind to localhost
110 ADDRESS => '192.168.1.1' # Bind to specified IP
111 "PORT"
113 This value will be passed to POE::Component::Server::SimpleHTTP to
114 bind to.
115 "HOSTNAME"
117 This value is for the HTTP::Request's URI to point to. If this is
118 not supplied, POE::Component::Server::SimpleHTTP will use
119 Sys::Hostname to find it.
120 "HEADERS"
122 This should be a hashref, that will become the default headers on
123 all HTTP::Response objects. You can override this in individual
124 requests by setting it via $response->header( ... )
125 The default header is: Server =>
127 'POE::Component::Server::SOAP/' . $VERSION
128 For more information, consult the HTTP::Headers module.
130 "MUSTUNDERSTAND"
132 This is a boolean value, controlling whether Server::SOAP will
133 check for this value in the Headers and Fault if it is present.
134 This will default to true.
135 "SIMPLEHTTP"
137 This allows you to pass options to the SimpleHTTP backend. One of
138 the real reasons is to support SSL in Server::SOAP, yay! To learn
139 how to use SSL, please consult the
140 POE::Component::Server::SimpleHTTP documentation. Of course, you
141 could totally screw up things, just use this with caution :)
142 You must pass a hash reference as the value, because it will be
144 expanded and put in the Server::SimpleHTTP->new() constructor.
145 Events
147 There are only a few ways to communicate with Server::SOAP.
148 "ADDMETHOD"
150 This event accepts four arguments:
151 - The intended session alias
152 - The intended session event
153 - The public service name ( not required -> defaults to session alias )
154 - The public method name ( not required -> defaults to session event )
155 Calling this event will add the method to the registry.
157 NOTE: This will overwrite the old definition of a method if it exists!
159 "DELMETHOD"
161 This event accepts two arguments:
162 - The service name
163 - The method name
164 Calling this event will remove the method from the registry.
166 NOTE: if the service now contains no methods, it will also be removed.
168 "DELSERVICE"
170 This event accepts one argument:
171 - The service name
172 Calling this event will remove the entire service from the registry.
174 "DONE"
176 This event accepts only one argument: the SOAP::Response object we sent to the handler.
177 Calling this event implies that this particular request is done, and will proceed to close the socket.
179 The content in $response->content() will be automatically serialized via SOAP::Lite's SOAP::Serializer
181 NOTE: This method automatically sets some parameters:
183 - HTTP Status = 200 ( if not defined )
184 - HTTP Header value of 'Content-Type' = 'text/xml'
185 To get greater throughput and response time, do not post() to the DONE event, call() it!
187 However, this will force your program to block while servicing SOAP requests...
188 "RAWDONE"
190 This event accepts only one argument: the SOAP::Response object we sent to the handler.
191 Calling this event implies that this particular request is done, and will proceed to close the socket.
193 The only difference between this and the DONE event is that the content in $response->content() will not
195 be serialized and passed through intact to the SOAP envelope. This is useful if you generate the xml yourself.
196 NOTE:
198 - The xml content does not need to have a <?xml version="1.0" encoding="UTF-8"> header
199 - In SOAP::Lite, the client sees '<foo>54</foo><bar>89</bar>' as '54' only!
200 The solution is to enclose the xml in another name, i.e. '<data><foo>54</foo><bar>89</bar></data>'
201 - If the xml is malformed or is not escaped properly, the client will get terribly confused!
202 It will be inserted here:
204 ...<soap:Body><namesp4:TestResponse xmlns:namesp4="http://localhost:32080/">YOURSTUFFHERE</namesp4:TestResponse></soap:Body>...
205 "FAULT"
207 This event accepts five arguments:
208 - the HTTP::Response object we sent to the handler
209 - SOAP Fault Code ( not required -> defaults to 'Server' )
210 - SOAP Fault String ( not required -> defaults to 'Application Faulted' )
211 - SOAP Fault Detail ( not required )
212 - SOAP Fault Actor ( not required )
213 Again, calling this event implies that this particular request is done, and will proceed to close the socket.
215 Calling this event will generate a SOAP Fault and return it to the client.
217 NOTE: This method automatically sets some parameters:
219 - HTTP Status = 500 ( if not defined )
220 - HTTP Header value of 'Content-Type' = 'text/xml'
221 - HTTP Content = SOAP Envelope of the fault ( overwriting anything that was there )
222 "RAWFAULT"
224 This event accepts only one argument: the SOAP::Response object we sent to the handler.
225 Calling this event implies that this particular request is done, and will proceed to close the socket.
227 The only difference between this and the FAULT event is that you are given freedom to create your own xml for the
229 fault. It will be passed through intact to the SOAP envelope. Be sure to read the SOAP specs :)
230 This is very similar to the RAWDONE event, so go read the notes up there!
232 It will be inserted here:
234 ...<soap:Body>YOURSTUFFHERE</soap:Body>...
235 "CLOSE"
237 This event accepts only one argument: the SOAP::Response object we sent to the handler.
238 Calling this event will proceed to close the socket, not sending any output.
240 "STARTLISTEN"
242 Starts the listening socket, if it was shut down
243 "STOPLISTEN"
245 Simply a wrapper for SHUTDOWN GRACEFUL, but will not shutdown Server::SOAP if there is no more requests
246 "SHUTDOWN"
248 Without arguments, Server::SOAP does this:
249 Close the listening socket
250 Kills all pending requests by closing their sockets
251 Removes it's alias
252 With an argument of 'GRACEFUL', Server::SOAP does this:
254 Close the listening socket
255 Waits for all pending requests to come in via DONE/FAULT/CLOSE, then removes it's alias
256 Processing Requests
258 if you're new to the world of SOAP, reading the documentation by the
259 excellent author of SOAP::Lite is recommended! It also would help to
260 read some stuff at http://www.soapware.org/ -> they have some excellent
261 links :)
262 Now, once you have set up the services/methods, what do you expect from
264 Server::SOAP? Every request is pretty straightforward, you just get a
265 Server::SOAP::Response object in ARG0.
266 The Server::SOAP::Response object contains a wealth of information about the specified request:
268 - There is the SimpleHTTP::Connection object, which gives you connection information
269 - There is the various SOAP accessors provided via Server::SOAP::Response
270 - There is the HTTP::Request object
271 Example information you can get:
273 $response->connection->remote_ip() # IP of the client
274 $response->soaprequest->uri() # Original URI
275 $response->soapmethod() # The SOAP method that was called
276 $response->soapbody() # The arguments to the method
277 Probably the most important part of SOAP::Response is the body of the
279 message, which contains the arguments to the method call. The data in
280 the body is a hash, for more information look at SOAP::Lite ->
281 SOAP::Deserializer.
282 I cannot guarantee what will be in the body, it is all up to the SOAP
284 serializer/deserializer. I can provide some examples:
285 NOTE: It is much easier to play around with parameters if they are properly encoded.
287 If you are using SOAP::Lite, make extensive use of SOAP::Data->name() to create parameters :)
288 Calling a SOAP method with no arguments:
290 print SOAP::Lite
291 -> uri('http://localhost:32080/')
292 -> proxy('http://localhost:32080/?session=MyServer')
293 -> Sum_Things()
294 -> result
295 The body will look like this:
297 $VAR1 = undef;
298 Calling a SOAP method with multiple arguments:
300 print SOAP::Lite
301 -> uri('http://localhost:32080/')
302 -> proxy('http://localhost:32080/?session=MyServer')
303 -> Sum_Things( 8, 6, 7, 5, 3, 0, 9, 183 )
304 -> result
305 The body will look like this:
307 $VAR1 = {
308 'c-gensym17' => '183',
309 'c-gensym5' => '6',
310 'c-gensym13' => '0',
311 'c-gensym11' => '3',
312 'c-gensym15' => '9',
313 'c-gensym9' => '5',
314 'c-gensym3' => '8',
315 'c-gensym7' => '7'
316 };
317 NOTE: The original array ordering can be received by sorting on the keys.
319 Calling a SOAP method with an arrayref
321 print SOAP::Lite
322 -> uri('http://localhost:32080/')
323 -> proxy('http://localhost:32080/?session=MyServer')
324 -> Sum_Things(
325 [ 8, 6, 7, 5, 3, 0, 9, 183 ]
326 )
327 -> result
328 The body will look like this:
330 $VAR1 = {
331 'Array' => [
332 '8',
333 '6',
334 '7',
335 '5',
336 '3',
337 '0',
338 '9',
339 '183'
340 ]
341 };
342 Calling a SOAP method with a hash:
344 print SOAP::Lite
345 -> uri('http://localhost:32080/')
346 -> proxy('http://localhost:32080/?session=MyServer')
347 -> Sum_Things( {
348 'FOO' => 'bax',
349 'Hello' => 'World!',
350 } )
351 -> result
352 The body will look like this:
354 $VAR1 = {
355 'c-gensym21' => {
356 'Hello' => 'World!',
357 'FOO' => 'bax',
358 }
359 };
360 Calling a SOAP method using SOAP::Data methods:
362 print SOAP::Lite
363 -> uri('http://localhost:32080/')
364 -> proxy('http://localhost:32080/?session=MyServer')
365 -> Sum_Things(
366 SOAP::Data->name( 'Foo', 'harz' ),
367 SOAP::Data->name( 'Param', 'value' ),
368 )-> result
369 The body will look like this:
371 $VAR1 = {
372 'Param' => 'value',
373 'Foo' => 'harz'
374 };
375 Simply experiment using Data::Dumper and you'll quickly get the hang of
377 it!
378 When you're done with the SOAP request, stuff whatever output you have
380 into the content of the response object.
381 $response->content( 'The result is ... ' );
383 The only thing left to do is send it off to the DONE event :)
385 $_[KERNEL]->post( 'MySOAP', 'DONE', $response );
387 If there's an error, you can send it to the FAULT event, which will
389 convert it into a SOAP fault.
390 # See this website for more details about what "SOAP Fault" is :)
392 # http://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383507
393 $_[KERNEL]->post( 'MySOAP', 'FAULT', $response, 'Client.Authentication', 'Invalid password' );
395 Server::SOAP Notes
397 This module is very picky about capitalization!
398 All of the options are uppercase, to avoid confusion.
400 You can enable debugging mode by doing this:
402 sub POE::Component::Server::SOAP::DEBUG () { 1 }
404 use POE::Component::Server::SOAP;
405 In the case you want to see the raw xml being received/sent to the
407 client, set DEBUG to 2.
408 Yes, I broke a lot of things in the release ( 1.01 ), but Rocco agreed
410 that it's best to break things as early as possible, so that
411 development can move on instead of being stuck on legacy issues.
412 Using SSL
414 So you want to use SSL in Server::SOAP? Here's a example on how to do
415 it:
416 POE::Component::Server::SOAP->new(
418 ...
419 'SIMPLEHTTP' => {
420 'SSLKEYCERT' => [ 'public-key.pem', 'public-cert.pem' ],
421 },
422 );
423 # And that's it provided you've already created the necessary key + certificate file :)
425 Ah, to use SSL in SOAP::Lite, simply use https://blah.com instead of
427 http://blah.com
428
