没有“访问控制允许来源”标头，即使您来自同一域的其他请求正在工作

我有一个奇怪的错误，没有'访问控制-允许-原产地'标头。我知道我必须授予源域（客户端）一些权限才能访问服务器，并且这与我提出的其他一些请求配合良好。但是当涉及到另一个要调用的函数时，它只说没有"访问控制-允许源"标头。

我的客户端托管在 heroku 中，服务器托管在 godaddy 中......

当该错误显示时，这是函数：

    } else {
        return response()->json(['message' => 'Validation Failed', 'success' => false, 'status' => 400, 'data' => array('class' => $ffSpendingRules)]);
    }

注意：如果我更改函数并使其简单，例如返回"test"，它不再显示源访问错误。我想知道函数是否有任何问题，为什么它不显示精算错误，而是显示 cors 错误。

有什么建议吗？
