Hook the request in a web page, and replace the url to another domain. When the request is xmlHttpRequest, it can transform the request to another domain or another request tunnel.
All above are done by just one config file.
link: https://www.cuiyongjian.com/docs-fetblock/
install the npm package in your project
npm install fet-block
import it in your project entry file, as early as possible
import { init } from 'fet-block'
// start fetBlock
init()
You should use you own config url in prodution environment. So you should pass a config url to fetBlock:
import { init } from 'fet-block'
// start fetBlock
init({
configUrl: 'https://yourdomain.com/config.json'
})
And now your project is ready to go!
Or you can use it with cdn link:
<script src="https://www.unpkg.com/browse/fet-block@1.0.0/dist/fetBlockLogic@1.0.0.umd.min.js"></script>
If you want to replace a url domain to another domain, you can config your domain to another domain
// config.json
{
"en": {
"img.mydemo.com": "bak.img.mydemo.com",
"api.mydemo.com": "bak.api.mydemo.com"
}
}
And if you want to use a special tunnel to send a request( eg: jsbridge), you can config the tunnel api name
in your project file like:
{
"zh": {
"img.mydemo.com": "sendRequestByJsBridge",
"api.mydemo.com": "sendRequestByJsBridge"
}
}
Like this, when the page send a request with img.mydemo.com
domain, it will be replace to use the jsbridge api sendRequestByJsBridge
to send. It is simple!
All of it occur under the mocked XmlHttpRequest hood.
If you want to develop fetBlock, you can clone this repo and run npm install
to install the dependencies. Then run npm run dev
to start the dev server.
Then you can install a proxy tool whistle
and config it :
npm install whistle -g
Config the whistle, first, create a rule like this:
www.mydemo.com http://localhost:52000
www.mydemo.com resHeaders://{corsjson}
img.mydemo.com http://localhost:52000
img.mydemo.com resHeaders://{corsjson}
api.mydemo.com http://localhost:52000
api.mydemo.com resHeaders://{corsjson}
bak.img.mydemo.com http://localhost:52000
bak.img.mydemo.com resHeaders://{corsjson}
bak.api.mydemo.com http://localhost:52000
bak.api.mydemo.com resHeaders://{corsjson}
And create a value for the corsjson
like this:
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET,POST,OPTIONS,PUT
Access-Control-Allow-Headers: *
Access-Control-Max-Age: 1
Then, you should config your chrome swichOmega
plugin to use the whistle
proxy.
Finally, You can visit https://www.mydemo.com
to see the demo page, and change the code in src folder, and it will audo build the dist.
