Question

尝试将OPTIONS发送到服务器时出错。错误：

{
    "code": 7,
    "message": "The service does not allow CORS traffic.",
    "details": [
        {
            "@type": "type.googleapis.com/google.rpc.DebugInfo",
            "stackEntries": [],
            "detail": "service_control"
        }
    ]
}

如果我发送GET请求（通过邮递员），我将得到正常响应。

节点服务器使用启用了cors的KOA.js

app.use(cors());

它可以在没有端点的情况下工作，因此我认为服务器中可能没有问题。

Answer 1

发送OPTIONS时使用什么路径？ “ /”或“ / api /用户”？

在Swagger中，您仅设置“ / api / user”路径，因此OPTIONS仅适用于该路径。
