Yodlee QuesAndAnswerDetails

Question

我正在尝试调试Yodlee站点身份验证问题。我将通过以下端点发送凭据: POST https://rest.developer.yodlee.com/services/srest/restserver/v1.0/jsonsdk/Refresh/putMFARequestForSite

这是我收到的错误消息：

{
  "errorOccurred": "true",
  "exceptionType": "com.yodlee.core.IllegalArgumentValueException",
  "referenceCode": "_4ef2f3e7-a750-4dfe-a16e-fa4254451897",
  "message": "Null argument specified for: QuesAndAnswerDetails[]"
}

我需要能够测试下拉(选择)通过MFA进行身份验证。我创建了一个DAG目录，并将其中一个DAG Security QA站点替换为我在googling搜索时找到的以下配置：

<login>
 <flowControlInfo>
 <delayBeforeChallenge>-1</delayBeforeChallenge>
 <delayBeforeLoginComplete>1</delayBeforeLoginComplete>
 <delayAfterLoginComplete>1</delayAfterLoginComplete>
 <expireToken>false</expireToken>
 </flowControlInfo>
 <MFAFlows>
 <MFAFlow flowOrder="1" isModeOfCommunication="1">
 <HelpTitle>MFA Help Title1</HelpTitle>
 <HelpContent>MFA Help Content1</HelpContent>
 <InfoTitle>MFA Info Title1</InfoTitle>
 <InfoContent>MFA Info Content1</InfoContent>
 <MFAChallengeList>
 <MFAChallenge questionType="text" >
 <MFAOption answerType = "dropdown">
 <questionLabel>Please select desired OTP
destination...</questionLabel>
 <answerOptions>
 <!-- The actual email or token will not be sent and is just a
placeholder to show the form -->
 <option isDefaultSelected="1" value="MOBILE_XXX-XXX-1234">MOBILE
XXX-XXX-1234</option>
 <option isDefaultSelected="0" value="HOME_XXX-XXX-2345">HOME XXXXXX-2345</option>
 <option isDefaultSelected="0" value="WORK_XXX-XXX-3456">WORK XXXXXX-3456</option>
 </answerOptions>
 </MFAOption>
 </MFAChallenge>
<MFAChallenge questionType="text" >
 <MFAOption answerType = "dropdown">
 <questionLabel>Please select desired OTP
destination1...</questionLabel>
 <answerOptions>
 <!-- The actual email or token will not be sent and is just a placeholder to show the form -->
 <option isDefaultSelected="1" value="TEXT">TEXT message</option>
 <option isDefaultSelected="0" value="PHONE">Phone Call</option>
 </answerOptions>
 </MFAOption>
 </MFAChallenge>
 </MFAChallengeList>
 </MFAFlow>
 <MFAFlow flowOrder="2">
 <HelpTitle>MFA Help Title1</HelpTitle>
 <HelpContent>MFA Help Content1</HelpContent>
 <InfoTitle>MFA Info Title1</InfoTitle>
 <InfoContent>MFA Info Content1</InfoContent>
 <TokenDetails>
 <DisplayString>Security Key</DisplayString>
 <Value>123456</Value>
 </TokenDetails>
 </MFAFlow>
 </MFAFlows>
</login>

为了找回MFA表单信息，我调用: POST https://rest.developer.yodlee.com/services/srest/restserver/v1.0/jsonsdk/Refresh/getMFAResponseForSite

我可以看到真实站点的下拉列表，但我不能让DAG站点重现相同的行为。我也读过https://developer.yodlee.com/assets/images/OTP_Documents/Implementation%20Manual%20for%20Enhanced%20MFA%20Support.pdf，但是当使用站点/提供者Id 16442时，我得到了一个403Yodlee内部错误响应。

我知道Can you provide an example of calling putMFARequestForSite with com.yodlee.core.mfarefresh.MFAQuesAnsResponse?，并且正在尝试实现建议的修复，但是我无法使用dag帐户进行测试。

谢谢!

Answer 1

我能够在生产中解决这个问题，方法是确保只传递预期的值，并按照预期的顺序发送它们，因为Can you provide an example of calling putMFARequestForSite with com.yodlee.core.mfarefresh.MFAQuesAnsResponse?会详细说明如何解决了为:QuesAndAnswerDetails[]指定的“空参数”错误。

不需要对providor accounts API进行更新，这将需要大量的返工。仍然无法使DAG工作。

从您的询问中，我看到您正在检查我们的遗留API。

我们建议您使用我们新的Yodlee API集成到您的系统中。
