其他时候我看到过这样的错误，因为我用相同的名称调用了一个变量和一个函数，但情况并非如此（或者我根本就是盲目的）。

虽然这不重要，但viewers的输出是['a4a6b1c0-e98a-42c8-abe9-f4289360c220', '152bff1c-e82e-49e1-92b6-f652c58d3145', '55a06a01-9956-4d7c-bfd0-5a2e6a27b62b']

之类的列表

Answer 1

由于viewers_buffer_health()没有settings的本地定义，因此它使用之前定义的函数。如果它的工作方式与viewers()相同，那么您需要在其当前参数集中添加settings参数。

Answer 2

settings是一个功能。

data = requests.get(settings()['endpoints']['node_buffer_health']).replace('<NODE_ID>', viewer)
