Hi all, still experimenting, but I wanted to use the simple HTTP server to run a service that produces direct HTML, so I can call that service directly from a web browser.
I tried to do this using REST, however any other way is fine too, just that I want to have simple URLs in the browser. I used the hello_svc example but had to make a few essential changes (see below) - now I wanted to check whether there are either better ideas or input in case my solution is not such a good idea (either by concept or technically). Many thx in advance!! tge Steps (this is with Axis2c 1.6.0): 1) have the simple http server set up and running 2) build and deploy the hello service from docs/docs 3) Use a web browser and access http://localhost:9090/axis2/services/hello/greet?name=tge (I found that somewhere on the web) This does not work at all, no matter what parameters I supply, I always get: "The requested URL was not found on this server." After reviewing other examples, I saw that the services.xml must contain a section like this: <operation name="greetFunc"> <parameter name="RESTMethod">GET</parameter> <parameter name="RESTLocation">greet</parameter> </operation> With this and the URL above it still does not work though 4) After finally putting in some debug output in axis2_hello_greet(), I saw that the passed in OM nodes are structured like this: <greetFunc><name>tge</name><name>tge</name></greetFunc> i.e. ALWAYS there is a two-level node structure whereas the hello_svc expects the text directly at the top-level node. So I put into axis2_hello_greet() this: ===== if (client_greeting_node && axiom_node_get_node_type(client_greeting_node, env) == AXIOM_ELEMENT) { client_greeting_node = axiom_node_get_first_child(client_greeting_node, env); } ===== Side-question: Why does the <name> tag exist twice? Probably a bug ... 5) Now I get a response in the web browser but it says that the XML does not contain formatting. Then I built a OM structure in axis2_hello_greet() that resembles primitive HTML like that: <html><head><title>Trallala</title></head><body>Hello Client!</body></html> 6) Still I get that result in the browser but browser still complains about missing formatting. I found that this is because Content-Type is "text/xml" and the challenge was to get that changed to "text/html" (after succeeding, it works). I read a lot through the code and discovered in http_sender.c this: === content_type_property = (axutil_property_t *) axis2_msg_ctx_get_property (msg_ctx, env, AXIS2_USER_DEFINED_HTTP_HEADER_CONTENT_TYPE); [...] === So I set that in hello_invoke(): === hello_invoke( axis2_svc_skeleton_t * svc_skeleton, const axutil_env_t * env, axiom_node_t * node, axis2_msg_ctx_t * msg_ctx) { /* TGE return axis2_hello_greet(env, node); */ axiom_node_t * resp = axis2_hello_greet(env, node); axutil_property_t * prop = axutil_property_create(env); if(prop) { axutil_hash_t * hash = (axutil_hash_t *) axutil_hash_make(env); if(hash) { axutil_hash_set(hash, AXIS2_HTTP_HEADER_CONTENT_TYPE, AXIS2_HASH_KEY_STRING, axutil_strdup(env, AXIS2_HTTP_HEADER_ACCEPT_TEXT_HTML)); axutil_property_set_value(prop, env, hash); axis2_msg_ctx_set_property(msg_ctx, env, AXIS2_USER_DEFINED_HTTP_HEADER_CONTENT_TYPE, prop); } } return resp; === 7) Still no success. After some debugging I found that the code in http_sender.c is actually not used by the HTTP server when responding, but rather axis2_http_transport_sender_invoke() in http_transport_sender.c. Here finally the content-type gets set hardcoded to either "text/xml" or "application/soap+xml". Now I added the code from above (with AXIS2_USER_DEFINED_HTTP_HEADER_CONTENT_TYPE) to axis2_http_transport_sender_invoke() and finally it worked as expected. ================================================ Now, the questions: a) Is there an easier/nicer way? I used REST because I found the example about calling the service using that fairly simple URL in the browser, but maybe there is another way? On the server side can change my service as I like b) If there is no better way, are there any design objections? c) If no, I'd submit the changed http_transport_sender.c as patch Many thx + regards, tge --------------------------------------------------------------------- To unsubscribe, e-mail: c-user-unsubscr...@axis.apache.org For additional commands, e-mail: c-user-h...@axis.apache.org
