Hello,
I'm facing a problem while trying to create a code DS2 to create and execute a post this is my code :
proc ds2; data test / overwrite=yes; /*dcl varchar(65000) response;*/ method init(); dcl package tap_restcallout scbQuery(); dcl integer rc sc; rc=scbQuery.createPost( 'https://hooks.slack.com/services/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'); sc=scbQuery.executePost(payload={"text": "tttttt"}); put 'RC=' rc; put 'SC= ' sc; end; enddata; run; quit;
Please find in attachement the code SAS DS2 for the package tap_restcallout
Log:
Your package contains an overloaded definition for the createPost method. One of the methods requires 5 parameters, the other 7:
method createPost(nvarchar(16384) url, int timeout, nvarchar(256) userid, nvarchar(256) password, in_out int rc);
method createPost(nvarchar(16384) url, nvarchar(16384) contentType, nvarchar(16384) accept, int timeout, nvarchar(256) userid, nvarchar(256) password, in_out int rc);
When you call the method in your code, DS2 looks for a method definition that has the same number of parameters. Your method call looks like this:
scbQuery.createPost( 'https://hooks.slack.com/services/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');
Because your method call only provides one parameter value, there is no method definition in the package that matches that pattern, and DS2 throws the error:
ERROR: Line 84: No method declaration for method createpost matches the given argument list.
Your call to the executePost method has the same problem, resulting in the error:
ERROR: Line 85: No method declaration for method executepost matches the given argument list.
When you call a method in a DS2 data program, you must provide values for all parameters in order to execute the method without error.

Both of the CreatePost methods in the code show 4 or more arguments. Your call in the code
rc=scbQuery.createPost( 'https://hooks.slack.com/services/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');
uses only one.
I don't do DS2 but that in a generic "number of parameters should match the parameters in the method call" way looks suspicious. Maybe you want another that only uses the URL??
