Question

当我进入异步get调用时遇到问题，但只有在CRM中调用时才会出现问题。我使用了我在Swagger端点上的代码中创建的URL，它可以工作。我已经在控制台应用上使用它，它可以工作，但现在，它无法在CRM中工作，我真的需要Ask-A-Friend或poll the audience这里，无论哪个工作。

我使用ILMerge来启用Newtonsoft.JSON库的使用。如果有任何其他信息我可以给你帮助，请告诉我。

以下是插件跟踪日志的例外情况：

解决了问题。在沙盒模式下，不支持集成安全性。因此，当我将默认凭据设置为“ true”时，CRM炸毁了我的GET调用。您必须使用服务帐户并将用户名和密码硬编码到代码中。我们将采取措施在较高级别的环境中对用户/密码进行加密，但是能够使用Web API并从CRM中获取外部结果很高兴
