我在这里尝试了所有的建议：
https://blogs.msdn.microsoft.com/jpsanders/2017/05/09/function-app-error-we-are-not-able-to-retrieve-the-runtime-master-key/

我正在使用运行时版本1.0.10917,但我已经尝试了~1并得到了相同的结果.

当我从门户网站删除该功能然后重新创建它时,似乎会发生这种情况.对于我们拥有的每项功能,它始终如一地发生.第一次创建函数时,它似乎有效.

用户很难为他们的应用程序发现这些错误,因为运行时不会将其记录在UX可以查询的任何位置.

此问题正在跟踪异常：https://github.com/Azure/azure-webjobs-sdk-script/issues/1832

我们仍然不完全确定为什么会这样.您是否有机会从其他应用程序重新发布密钥？ (编辑：或删除并重新创建具有相同名称的应用程序)这些密钥由功能应用程序特定密钥加密,并且不会在该上下文之外工作.

修复：从Fabio Cavalcante复制

can you delete (or rename) the host.json file in d:\home\data\Functions\secrets\ and retry? This will force the runtime to re-create those secrets for that environment. Keep in mind that this would also change your master and default keys.
