提供商托管的应用程序：TokenHelper无权获取上下文

问题描述

我遵循"打包并发布高可信度SharePoint加载项"将Provider Hosted App部署到生产环境的文章。它安装了正确的SSL证书，它在SharePoint中注册并且TokenHelper类被修改。对于网站和网站集，App
权限设置为完全控制。

当我使用  TokenHelper.CreateAppEventClientContext（properties，
false） 或  TokenHelper.CreateRemoteEventReceiverClientContext（properties） 方法
获取  ClientContext ，它返回null，代码抛出401 Unauthorized exception。

当我手动创建并提供农场管理员帐户的凭据时，我得到了一个正确的ClientContext，但它不是一个可接受的生产解决方案。另外，从这两种方法来看，正确的方法是什么在这种情况下获取ClientContext？

解决方案

I followed the "Package and publish high-trust SharePoint Add-ins" article to deploy Provider Hosted App to production environment. It has a proper SSL certificate installed, it's registered within SharePoint and TokenHelper class is modified. App permissions are set to Full Control for web and site collection.

When I use TokenHelper.CreateAppEventClientContext(properties, false) or TokenHelper.CreateRemoteEventReceiverClientContext(properties) methods to get ClientContext, it's returned null and the code throws 401 Unauthorized exception.

I get a proper ClientContext when I create it manually and provide the credentials of farm admin account, but it's not an acceptable solution for production. Also, from the two methods, what is the correct way to get ClientContext in this case?
