Non perché sia una buona idea, ma in modo che nessun altro debba capire come utilizzare le orribili stored procedure sp_OAxxx...
Ecco un aggiornamento alla mia antica stored procedure HTTP per utilizzare sia WinHttp che impostare quell'opzione. La proprietà Option è una "proprietà indicizzata", quindi chiamarla con sp_OASetProperty è strano.
create or alter procedure get_http @url varchar(2000)
as
begin
/*
exec get_http 'https://www.bing.com'
*/
declare @hr int;
declare @win int;
declare @errorMessage varchar(2000);
begin try
EXEC @hr=sp_OACreate 'WinHttp.WinHttpRequest.5.1',@win OUT
IF @hr <> 0
begin;
set @errorMessage = concat('sp_OACreate failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
EXEC @hr=sp_OAMethod @win, 'Open',NULL,'GET',@url,'false'
IF @hr <> 0
begin;
set @errorMessage = concat('Open failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
--Option is an indexed property, so newvalue = 2048 and index = 9
--sp_OASetProperty objecttoken , propertyname , newvalue [ , index... ]
EXEC @hr=sp_OASetProperty @win, 'Option', 2048, 9
IF @hr <> 0
begin;
set @errorMessage = concat('set Option failed ', convert(varchar(20),cast(@hr as varbinary(4)),1) );
throw 60000, @errorMessage, 1;
end;
EXEC @hr=sp_OAMethod @win,'Send'
IF @hr <> 0
begin;
set @errorMessage = concat('Send failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
declare @status int
EXEC @hr=sp_OAGetProperty @win,'Status', @status out
IF @hr <> 0
begin;
set @errorMessage = concat('get Status failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
if @status <> 200
begin;
set @errorMessage = concat('web request failed ', @status);
throw 60000, @errorMessage, 1;
end;
declare @response table(text nvarchar(max));
insert into @response(text)
EXEC @hr=sp_OAGetProperty @win,'ResponseText';
IF @hr <> 0
begin;
set @errorMessage = concat('get ResponseText failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
select *
from @response
EXEC @hr=sp_OADestroy @win
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win;
end try
begin catch
declare @error varchar(200) = error_message()
declare @source varchar(200);
declare @description varchar(200);
declare @helpfile varchar(200);
declare @helpid int;
exec sp_OAGetErrorInfo @win, @source out, @description out, @helpfile out, @helpid out;
declare @msg varchar(max) = concat('COM Failure ', @error,' ',@source,' ',@description)
EXEC @hr=sp_OADestroy @win;
--IF @hr <> 0 EXEC sp_OAGetErrorInfo @win;
throw 60000, @msg, 1;
end catch
end
