SecurityTokenHandlers均无法读取“ securityToken”

Question

我的情况：我使用ADFS创建了一个具有身份验证的新Web应用程序。我更新了所有nuget程序包并运行该应用程序。我不断收到此错误消息：

from typing import Callable

def make_matrix(num_rows: int,
                num_cols: int,
                entry_fn: Callable[[int, int], float]) -> Matrix:
    """
    Returns a num_rows x num_cols matrix
    whose (i,j)-th entry is entry_fn(i, j)
    """
    return [[entry_fn(i, j)             # given i, create a list
             for j in range(num_cols)]  #   [entry_fn(i, 0), ... ]
            for i in range(num_rows)]   # create one list for each i

def kronecker_delta(i: int, j:int) -> float:
    return 1.0 if (i == j) else 0.0

print(make_matrix(4, 4, kronecker_delta))
