怎么通过请求上下文异步传递信息

This topic created in 855 days ago, the information mentioned may be changed or developed.

目前使用了 express-http-context2 ，但是感觉有 bug ，在后续中无法获取设置的值

const app = express();
app.use(middleware); // use http context

if (!excludeAuth(req)) {
	await verifyJWT(req, resp);
console.log(get(HTTP_CONTEXT.ORG_ID));
}

req

上下文

await

const

https://www.npmjs.com/package/express-http-context

感觉可能是写法问题？检查版本
1. Install: npm install --save express-http-context
(Note: For node v4-7, use the legacy version: npm install --save express-http-context@<1.0.0)

2. Make sure you require express-http-context in the first row of your app. Some popular packages use async which breaks CLS.

3. Node 10.0.x - 10.3.x are not supported. V8 version 6.6 introduced a bug that breaks async_hooks during async/await. Node 10.4.x uses V8 v6.7 in which the bug is fixed. See: https://github.com/nodejs/node/issues/20274.

后面尝试了下，设置值不在 await 方法里可以获取，可能是跟这个上下是基于回调有关系，具体原因还没搞明白

ps:感谢楼上

没必要用这个插件啊，直接用 asynclocalstorage 一样简单，还可以自定义 type
