oracle utl_smtp 500 bad syntax,改进oracle utl_mail包的smtp_server设定和密码验证不足
一.通过utl_smtp发送邮件的范例
DECLARE
c utl_smtp.connection;
BEGIN
c := utl_smtp.open_connection('smtp.exmail.qq.com');
utl_smtp.helo(c, 'smtp.exmail.qq.com');
utl_smtp.auth(c => c,
username => 'selectshen@foxmail.com',
password => 'mail_password',
schemes => 'LOGIN');
utl_smtp.mail(c, 'selectshen@foxmail.com');
utl_smtp.rcpt(c, '20084622@qq.com');
utl_smtp.open_data(c);
utl_smtp.write_data(c,
'From' || ': ' || '' ||
utl_tcp.CRLF);
utl_smtp.write_data(c,
'To' || ': ' || '<20084622@qq.com>' ||
utl_tcp.CRLF);
utl_smtp.write_raw_data(c, utl_raw.cast_to_raw(convert('Subject' || ': ' || '来自oracle数据库的邮件' || utl_tcp.CRLF,'ZHS16GBK')));
UTL_SMTP.WRITE_DATA(c,
'Content-Type: '||'text/plain; charset=gb2312'||utl_tcp.CRLF);
utl_smtp.write_raw_data(c, utl_raw.cast_to_raw(convert( utl_tcp.CRLF || '你好,oracle!','ZHS16GBK')));
utl_smtp.close_data(c);
utl_smtp.quit(c);
EXCEPTION
WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
BEGIN
utl_smtp.quit(c);
EXCEPTION
WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
NULL;
END;
raise_application_error(-20000,
'Failed to send mail due to the following error: ' ||
sqlerrm);
END;
二.改进utl_mail包
oracle从10.1.0.2提供一个ult_mail的包,用于发送邮件,它是对utl_smtp进行了封装,简化发邮件的步骤.
但存在的不足:
1.需要通过alter session或alter system去设定smtp_server
2.无法使用密码验证
通过对utl_mail包进行改进,将smtp_server的设定放在发送邮件的参数中,并在发送的存储过程中加入密码验证,去增强实用性.
发邮件的存储过程使用方法,可参考 How to Use the UTL_MAIL Package (文档 ID 269375.1).
并且要注意,从11g开始,如果不是sys用户去发邮件,要设定ACL,可参考ORA-24247 Using UTL_TCP, UTL_HTTP, UTL_SMTP And UTL_MAIL With 11gR1 Or Later (文档 ID 1209644.1).
下面是简单的调用示例:
#改进后的包名个人定义为utl_email
UTL_EMAIL.SEND发送不含附件的邮件.
例如:
begin
scott.UTL_EMAIL.SEND(SMTP_SERVER => 'smtp.exmail.qq.com',
SENDER => 'selectshen@foxmail.com',
AUTH_PASSWORD => 'mail_password',
recipients => '20084622@qq.com',
subject => '数据库测试',
message => '中文',
mime_type => 'text/plain; charset=utf8'
);
end;
UTL_EMAIL.SEND_ATTACH_VARCHAR2发送包含文本附件的邮件.
例如:
begin
scott.UTL_EMAIL.SEND_ATTACH_VARCHAR2(SMTP_SERVER => 'smtp.exmail.qq.com',
SENDER => 'selectshen@foxmail.com',
AUTH_PASSWORD => 'mail_password',
recipients => '20084622@qq.com',
subject => 'oracle数据库发送的测试邮件',
message => '你好,oracle!',
mime_type => 'text/plain; charset=utf8',
attachment => '这是附件里的内容',
ATT_INLINE => FALSE,
att_filename =>'a.txt'
);
end;
UTL_EMAIL.send_attach_raw发送包含二进制附件的邮件.
以下是改进后的utl_email包的定义,用户只需新建以下包即可:#PACKAGECREATE OR REPLACE PACKAGE utl_email AUTHID CURRENT_USER AS
