  1. import { NODE_ENV } from 'common/constants';
  3. export function getAllowedOrigins() {
  4.   // https://github.com/expressjs/cors/issues/272#issuecomment-1186236472
  5.   let allowedOrigins: string[] = [];
  6.   if (NODE_ENV === 'development') {
  7.     allowedOrigins = ['http://www.example.local', 'https://www.example.local'];
  8.   } else if (NODE_ENV === 'test') {
  9.     allowedOrigins = [
  10.       'http://staging.example.com',
  11.       'https://staging.example.com',
  12.     ];

  14.     allowedOrigins = ['http://www.example.com', 'https://www.example.com'];
  15.   }

  • 我正在尝试使用上述文件在我的node.js express应用程序上设置cors

这是我的Express应用程序文件

  1. ...
  2. const app = express();
  4. app.use(rTracer.expressMiddleware());
  5. app.use(requestLogger);
  7. app.use(
  8.   cors({
  9.     credentials: true,
  10.     origin: getAllowedOrigins(),
  11.   }),
  12. );
  13. ...

  • 我的本地开发、测试和生产环境运行在localhost：8000上
  • 我还有一个docker开发，它使用自签名的https证书在nginx后面的API.example.local上运行
  • 我的生产环境最终运行在AWS上，certbot支持nginx后面的https

这就是我在AWS上运行的最终产品nginx.conf文件的样子

  • 1.我是否需要在允许的来源下分别列出https和http的域名？*

您可以使用regExp，它可以匹配http和https，并包括subdomain：

  1. import { NODE_ENV } from "common/constants";
  3. export function getAllowedOrigins() {
  5.   let allowedOrigins;
  6.   if (NODE_ENV === "development") {
  7.     allowedOrigins = /example\.com$/;
  8.   } else if (NODE_ENV === "test") {
  9.     allowedOrigins = /staging\.example\.com$/;
  10.   } else if (NODE_ENV === "production") {
  11.     allowedOrigins = "https://www.example.com"; // for production https prefered
  12.   }
  13.   return allowedOrigins;
  14. }

  • 2.我是否需要以任何方式修改我的nginx.conf文件来处理cors？*

不，你不需要它，即使你可以，因为控制在一个地方更好的许多。让表达处理它。

  • 3.我是否需要将localhost:8000包括在生产中允许的原产地？*

绝对不是，生产环境是一个隔离的环境，没有必要包括localhost
