Cross-domain problems of local development of WEB projects separated from front and rear ends

Development environment: MAC OS, APACHE, PHP7.2, ThinkPHP5, vue.js 3.0, axios.

the back-end interface is developed by ThinkPHP5, and cross-domain headers have been added to return the data. Deployed on the local IP:192.168.0.3:80.
the data returned by the interface can be accessed through POSTMAN.

you've already used cli. Why don't you use the proxy agent?


that specializes in solving this kind of problem. There are proxy settings in

vue-cli .
but! If you're afraid of trouble, don't say anything. Why don't you try this, once and for all.
is probably the simplest and roughest way to solve cross-domain problems in the Eastern Hemisphere :
1. chrome copy shortcuts.
2. Right-click the shortcut and change the property-destination
to the following (make sure these installation paths exist)

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir=C:\Program Files (x86)\Google\Chrome\Application

3. Advantages: you can even debug the online interface on the local page.


now in the development stage, let the backend program open cross-domain and solve the problem of hanging Access-Control-Allow-Origin (the error prompted by console, you should have sent a post request, but it is a complex request. The browser sends a request of OPTIONS type, but the backend does not process this type of request). It is not recommended to use jsonp to solve


or nginx


.
const APIS = [
    '/api/'
]
const target = ''

const onProxyReq = proxyReq => {}
module.exports = APIS.reduce((result, curr) => {
    result[curr] = {
        target,
        onProxyReq,
        changeOrigin: true
    }
    return result
}, {})

then configure proxyTable in config ~
