如何从AdalException检索JSON响应？ [英] How can I retrieve the JSON response from an AdalException?

问题描述

如果我从服务中调用AuthenticationContext.AcquireToken，则在某些情况下会引发AdalException，因为我发送的令牌缺少必填声明。我调用AcquireToken时的响应中包含缺少声明的JSON。我希望能够获取该JSON（特别是缺少的声明信息），以便尝试用该丢失的声明重新授权用户。

If I call AuthenticationContext.AcquireToken from our service, it throws an AdalException in a certain situation because the token I’m sending is missing a required claim. The response from when I call AcquireToken contains JSON in it with the claim that is missing. I want to be able to get at that JSON (specifically the missing claim information) so I can attempt to reauthorize the user with that missing claim.

一旦我发现AdalException，通过调用AcquireToken，如何获得JSON响应以找出缺少的声明？如果我尝试从AdalException上的innerException获取响应流：

Once I catch the AdalException from calling AcquireToken, how can I get at the JSON response to find out which claim was missing? If I try to get the response stream from the innerException on the AdalException:

catch (AdalException ex)
{
    WebException webex = (WebException)ex.InnerException;
    WebResponse response = webex.Response;
    Stream responseStream = response.GetResponseStream();
    ...

...然后我得到的responseStream包含CanRead，CanSeek和CanWrite属性全部设置为false。因此，我不确定如何检索丢失的Claims参数，因为我实际上无法从该流中读取。

… then the responseStream I get has the CanRead, CanSeek, and CanWrite properties all set to false. Consequently, I’m not sure how to retrieve the missing claims parameter since I can’t actually read from that stream.

推荐答案

返回整个服务器JSON响应的修复是在ADAL v3中进行的。 Github链接：- https://github.com/AzureAD/ azure-activedirectory-library-for-dotnet / issues / 513
在ADAL v2中尚不可用。

The fix to return the entire server JSON response is made in ADAL v3. Github Link :- https://github.com/AzureAD/azure-activedirectory-library-for-dotnet/issues/513 It is not yet available in ADAL v2.
