我正在尝试与 Google 日历交谈。我的身份验证有问题。我写下下面的代码。
create or replace function authenticate_service(
p_email in varchar2,
p_password in varchar2) return varchar2 is
l_request utl_http.req;
l_response utl_http.resp;
l_params varchar2(255);
l_resp_data varchar2(4000);
l_auth_token varchar2(4000); begin
-- access the oracle wallet to allow us to make an https request
utl_http.set_wallet(
path => 'file: ***',
password => '***');
-- set up the request body with our credentials
l_params := 'Email=' || p_email || '&Passwd=' || p_password ||
'&service=cl' || '&source=e-DBA-test-1.0';
l_request := utl_http.begin_request(
'https://www.google.com/accounts/ClientLogin',
'POST',
'HTTP/1.1');
-- set the request headers
utl_http.set_header(
l_request,
'Content-Type',
'application/x-www-form-urlencoded');
utl_http.set_header(
l_request,
'Content-Length',
length(l_params));
-- write out the request body
utl_http.write_text( l_request, l_params );
-- get the response
l_response := utl_http.get_response( r => l_request );
dbms_output.put_line('Status Code: '||l_response.status_code);
begin
loop
utl_http.read_line( r => l_response, data => l_resp_data,remove_crlf => TRUE);
if substr(l_resp_data, 1, 5) = 'Auth=' then
l_auth_token := substr(l_resp_data, 6);
end if;
end loop;
exception
when utl_http.end_of_body then
null;
end;
utl_http.end_response ( l_response );
dbms_output.put_line(l_auth_token); return l_auth_token;
end authenticate_service;
一切正常,但是...当我尝试连续调用几次身份验证时,有时我发现此错误 Oracle ORA-03113: end-of-file on communication channel 然后 ORA-03114: not connected to ORACLE。我不知道它为什么会发生以及如何解决这个问题。
