我通过选择Access Control Enable role-based user authorization功能创建了一个新应用程序是 APEX 19.1。默认的身份验证方案Application Express Authentication工作得很好。但是当我将其更改为 OpenID Connect 并运行该应用程序时，出现以下错误

- ora_sqlerrm: ORA-29273: HTTP request failed

这是错误回溯

我尝试了以下方法来解决错误

BEGIN
    DBMS_NETWORK_ACL_ADMIN.APPEND_HOST_ACE(
        host => '*',
        ace => xs$ace_type(privilege_list => xs$name_list('connect'),
                           principal_name => 'apex_db_user',
                           principal_type => xs_acl.ptype_db));
END;
/

该声明确实继续，但我得到了同样的错误。

然后我想可能是因为我没有使用 SSL。所以我更改了 default.xml 文件并添加了以下条目

<entry key="security.verifySSL">false</entry>

我是 APEX 的新手，所以可能我遗漏了一些东西。功能Access Control Enable role-based user authorization够不够？

这是 Oracle 中的一个安全主题，默认情况下关闭模式的所有网络权限。

使用 sys 作为 sysdba 帐户，执行以下代码。不要忘记更改架构名称和域。

-- Execute as sysdba
DECLARE
  l_acl       VARCHAR2(100) := 'aclname.xml';
  l_desc      VARCHAR2(100) := 'description';
  l_principal VARCHAR2(30)  := 'APEX_SCHEMANAME'; -- UPPERCASE if applies
  l_host      VARCHAR2(100) := 'yourdomain.com'; --hostname to reach
BEGIN

  -- Connection rights
  dbms_network_acl_admin.create_acl(l_acl, l_desc, l_principal, TRUE, 'connect');
 
  -- DNS resolution privilege
  dbms_network_acl_admin.add_privilege(l_acl, l_principal, TRUE, 'resolve');
 
  dbms_network_acl_admin.assign_acl(l_acl, l_host);
 
  COMMIT;
END;

您可以知道执行下一个查询的架构名称。

    SELECT TABLE_OWNER FROM all_synonyms
WHERE SYNONYM_NAME = 'WWV_FLOW' and OWNER = 'PUBLIC'
