Catalog picturesOwn plain English explanation:
First, you install Http-proxy-middleware, and npm install http-proxy-middleware --save-dev then you reference the page.
app.middleware = [ proxyMiddleware([‘/api/message/alllist/*‘], { target: ‘http://***.com‘, changeOrigin: true }) ];Proxy the server to this address and match the route/api/message/alllist/*
Start the server, you can use node's own command node App.js or you can use the command expess in the framework of NPM Start (Package.json), this time the terminal is displayed as
Finally, enter the address in the browser: localhost:3100, note that the address in this is the address of the server you launched yourself and the port; My port number is 3100.
View terminal changes after the visit, display the request successfully
The data you requested at this point is the data on the server you are acting on, and this is my insight into cross-domain requests with node +express+http-proxy-middleware, if there is something wrong with the great God, and welcome to the same-minded comrades in the study of technology.Use node + Express + Http-proxy-middleware to implement a detailed instance of the front end agent cross-domain.
