@Ed: I tested your query and got the error: Certificate validation failure.

Connected to:
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production

This information is great but I’m having problems calling a url with several parameters. SELECT UTL_HTTP.REQUEST( https://realtime.gpcatalogue.com/servlet/GPCRealTime?Query=Logon&Alias=GXSRETL&Userid=GXSREAL&Password=REALTIME) FROM DUAL

The query returns session timed out but pasting it in the browser it says login successfully…

Great code example. I ran into a problem however when I used this in a loop. I got “ORA-29270: too many open HTTP requests” errors. I finally found a fix that seemed to work… Exception When UTL_HTTP.END_OF_BODY Then UTL_HTTP.END_RESPONSE (l_http_resp);

For those of you who want to HTTP post some parameters to another site, use the following code:

set serveroutput on; exec dbms_output.enable(1000000000);

set escape '\'

DECLARE req UTL_HTTP.REQ; resp UTL_HTTP.RESP; value VARCHAR2(1024);

-- URL to post to v_url VARCHAR2(200) := 'http://T97040476TA9000/core_dmt/withdraw_job.php';

-- Post Parameters v_param VARCHAR2(500) := 'pwd=coredmt8567\&core_id=12223\&type=PK\&reason=This is the test reason'; v_param_length NUMBER := length(v_param); BEGIN -- Set up proxy servers if required -- UTL_HTTP.SET_PROXY('proxy.my-company.com', 'corp.my-company.com'); req := UTL_HTTP.BEGIN_REQUEST (url=> v_url, method => 'POST'); -- UTL_HTTP.SET_HEADER(req, 'User-Agent', 'Mozilla/4.0'); UTL_HTTP.SET_HEADER (r => req, name => 'Content-Type',
value => 'application/x-www-form-urlencoded'); UTL_HTTP.SET_HEADER (r => req, name => 'Content-Length', value => v_param_length); UTL_HTTP.WRITE_TEXT (r => req, data => v_param);

resp := UTL_HTTP.GET_RESPONSE(req); LOOP UTL_HTTP.READ_LINE(resp, value, TRUE); DBMS_OUTPUT.PUT_LINE(value); END LOOP; UTL_HTTP.END_RESPONSE(resp); EXCEPTION WHEN UTL_HTTP.END_OF_BODY THEN UTL_HTTP.END_RESPONSE(resp); END; /

Very nice, saved me hours of work I am sure!

It would be nice to know how to encode form elements into "x-www-form-Urlencoded" format and post. The examples I found using Oracle did it in Java, which I would rather avoid. XML will work however.

Hmmmm. I was hoping that wouldn’t be the answer

Oh well, guess I have to figure something else out then for doing this.

taneal, it seems that you need to decrypt the data on the other end.

This is really interesting. How would this work on a page that encrypts the names/ID’s of form elements? For instance, when a user creates a job post on our site, I then take them to a page that loads Craigslist into an IFRAME. I want to be able to populate the fields with the information they entered on our site (so they don’t have to re-type everything). I’ve been having problems with it though.

Hi Eddie

The procedure works, as in it posts to the URL with the parameters, but it also throws an error:

SQL execution error, ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1029 ORA-29261: bad argument ORA-06512: at "HH.UTIL_PKG", line 101

This is how im using the code (its in a trigger)

DECLARE v_url varchar2(200); l_data clob := '1'; ....

BEGIN ... select REPLACE(REPLACE(:new.input_value,' ',NULL),'-',NULL) into v_phone_num from dual; -- select REPLACE(REPLACE(1234567,' ',NULL),'-',NULL) into v_phone_num from dual; v_url := 'http://www.******.com/test.asp?pnum=12345' || '&' || 'phone=' || v_phone_num;

util_pkg.http_post(p_url_in => v_url, p_data_in => l_data);

Im only passing 2 arguments, p_url and p_data_in, what is the bad argument error about? Any help would be greatly appreciated.
