Google App Engine CORS“解析 ./app.yaml 时出错：未知的 url 处理程序类型”

我正在尝试将 CORS 应用到我的一个应用程序引擎，但遇到错误。我尝试查看其他答案（间距）的建议，但仍然错误：

app.yaml

runtime: nodejs10

env_variables:
  NODE_ENV: production
  CLOUD_SQL_CONNECTION_NAME: domain-name-server:australia-southeast1:db_name

handlers:  
- url: /.*
  http_headers:
    Access-Control-Allow-Origin: https://domain_name-fixed.appspot.com/

Errors

ERROR: (gcloud.app.deploy) An error occurred while parsing file: [/home/project/domain_name-server/app.yaml]

NodeJS Cors设置

let cors = require("cors")

let origin =
    [
        "http://localhost:8080",
        `http://${ip.address()}:8080`,
        "http://localhost:4000",
        `http://${ip.address()}:4000`,
        "https://domain_name-fixed.appspot.com/"
    ]

app.use(cors({
    origin,
    credentials: true
}))

您只能为静态文件设置 HTTP 标头。您需要在nodejs代码中执行CORS部分。
