在 Azure Functions 中遇到错误 401 问题

Question

我尝试在 Azure 函数中使用多个函数，但是虽然创建的第一个函数正常工作（返回状态 200），但第二个函数始终返回 401 错误，它是必须接受一个 JSON 的代码并返回另一个 JSON。我已经启用和禁用了 CORS，将 AuthLevel 更改为匿名，等等，但它总是返回这个 401 错误。我创建了第三个测试函数，它也返回 401 错误。它的代码无非就是Azure Function的“Hello World”，没有什么特别之处。

有人遇到过这种情况吗？你知道它可能是什么吗？

我不知道这是否相关，但是当尝试在本地运行第二个或第三个函数时，此错误会返回给我。然而，他引用了第一个代码，该代码有效：

我尝试更改功能、匿名和管理员的权限，但都不起作用。我还启用了 CORS。

您可能正在尝试使用仅限第一个函数的功能密钥来验证其他函数。

在 Azure 门户中，如果您选择一个功能，然后从菜单中选择“功能键”，则会返回仅对该功能有效的键。

相反，在功能应用程序本身，从菜单中选择“应用程序键”，然后尝试使用应用程序键而不是功能键。应用程序密钥将可以访问应用程序中的所有功能。
