我有一个作为服务提供者工作的 SimpleSamlPHP 实现，所以工作流程如下：

IdP 将断言发送到我的 ACS URL：

/simplesaml/module.php/saml/sp/saml2-acs.php/default-sp

但是看起来他进行了身份验证并被重定向到

/simplesaml/module.php/saml/sp/saml2-acs.php

这会引发错误，因为没有指定 authsource（/default-sp 部分）：

SimpleSAML_Error_Error: UNHANDLEDEXCEPTION
Backtrace:
0 *\simplesamlphp\www\module.php:180 (N/A)
Caused by: SimpleSAML_Error_Exception: No authentication source with id false found.
    Backtrace:
    2 *\simplesamlphp\lib\SimpleSAML\Auth\Source.php:242 (SimpleSAML_Auth_Source::getById)
    1 *\simplesamlphp\modules\saml\www\sp\saml2-acs.php:8 (require)
    0 *\simplesamlphp\www\module.php:135 (N/A)

但是，它也有一组 PHP 错误输出到页面：

Warning: array_key_exists(): The first argument should be either a string or an integer in *\simplesamlphp\lib\SimpleSAML\Configuration.php on line 314 
Warning: Cannot modify header information - headers already sent by (output started at *\simplesamlphp\lib\SimpleSAML\Configuration.php:314) in *\simplesamlphp\lib\SimpleSAML\Error\Error.php on line 191 
Warning: Cannot modify header information - headers already sent by (output started at *\simplesamlphp\lib\SimpleSAML\Configuration.php:314) in *\simplesamlphp\templates\includes\header.php on line 40

（我已取出目录路径并替换为 * - 这不是正常的）

我无法确定这是 SimpleSamlPHP 的错误，还是（更有可能）设置不正确。我的 authsources 和元数据如下：

saml20-idp-remote.php：

$metadata['https://app.onelogin.com/saml/metadata/391645'] = array(
    'name' => 'FSSO',
    'SingleSignOnService' => 'https://app.onelogin.com/trust/saml2/http-post/sso/391645',
    'AssertionConsumerservice' => 'https://www.fbjni.com/simplesaml/module.php/saml/sp/saml2-acs.php/default-sp',
    'SingleLogoutService' => 'https://www.fbjni.com/simplesaml/module.php/saml/sp/saml2-logout.php/default-sp',
    'certData'          => '[rawCertificateData]'
);

authsources.php：

'default-sp' => array(
    'saml:SP',
    'RelayState' => 'https://www.fbjni.com/',
    'entityID' => 'https://app.onelogin.com/saml/metadata/391645',
),

您的 IdP 元数据可能存在一些问题。SimpleSAMLphp 包含一个元数据解析器，它负责将 IdP 配置详细信息转换为 SimpleSAMLphp 所需的格式。此处的 SimpleSAMLphp 文档中简要提到了此功能：https ://simplesamlphp.org/docs/1.8/simplesamlphp-sp#section_2

根据您上面的示例，您应该能够访问元数据解析器https://www.fbjni.com/simplesaml/admin/metadata-converter.php。

在您上面的特定示例中，从https://app.onelogin.com/saml/metadata/391645您的 SimpleSAMLphp 安装中下载 OneLogin 元数据并将此 XML 复制到元数据解析器中。

转换元数据后，将上面现有的 IdP 配置替换为元数据解析器的输出，看起来应该更像这样：

$metadata['https://app.onelogin.com/saml/metadata/391645'] = array (
  'entityid' => 'https://app.onelogin.com/saml/metadata/391645',
  'contacts' => 
  array (
    0 => 
    array (
      'contactType' => 'technical',
      'surName' => 'Support',
      'emailAddress' => 
      array (
        0 => 'support@onelogin.com',
      ),
    ),
  ),
  'metadata-set' => 'saml20-idp-remote',
  'SingleSignOnService' => 
  array (
    0 => 
    array (
      'Binding' => 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect',
      'Location' => 'https://app.onelogin.com/trust/saml2/http-post/sso/391645',
    ),
    1 => 
    array (
      'Binding' => 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST',
      'Location' => 'https://app.onelogin.com/trust/saml2/http-post/sso/391645',
    ),
    2 => 
    array (
      'Binding' => 'urn:oasis:names:tc:SAML:2.0:bindings:SOAP',
      'Location' => 'https://app.onelogin.com/trust/saml2/soap/sso/391645',

此外，您应该对 authsources.php 配置进行一些更改。您的 SP 的“entityID”通常是您的应用程序的 URL，而不是您选择的 IdP 的标识符。您可以为 SP 指定默认 IdP，如下所示：

'default-sp' => array(
    'saml:SP',
    'entityID' => 'https://www.fbjni.com/',
    'RelayState' => 'https://www.fbjni.com/',
    'idp' => 'https://app.onelogin.com/saml/metadata/391645'
