辦公室365應用程序創建錯誤：類型'Microsoft.Office365.OAuth.MissingConfigurationValueException'的異常被拋出

Question

我在VS 2013中開發了一個Office 365應用程序。通過連接的服務連接到我的O365帳戶。但是代碼被失敗以下行：

_discoveryContext = await DiscoveryContext.CreateAsync(); 

而且我得到的例外是如下：

Exception of type 'Microsoft.Office365.OAuth.MissingConfigurationValueException' was thrown. 
    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: Microsoft.Office365.OAuth.MissingConfigurationValueException: Exception of type 'Microsoft.Office365.OAuth.MissingConfigurationValueException' was thrown. 

Source Error: 



Line 32:    if (_discoveryContext == null) 
Line 33:    { 
Line 34:     _discoveryContext = await DiscoveryContext.CreateAsync(); 
Line 35:    } 
Line 36:

Answer 1

這聽起來像所連接的服務嚮導莫名其妙地失敗。檢查您的Web.config文件。它應該具有以下鍵appSettings下：

<add key="ida:ClientID" value="SOME GUID HERE" /> 
<add key="ida:Password" value="SOME BASE64 STRING HERE" /> 
<add key="ida:AuthorizationUri" value="https://login.windows.net" /> 

如果他們丟失，您可能需要重新添加連接的服務。
