MV3 declarativeNetRequest how to redirect to a url create by "createObjectURL"

[Dramalf]

how can I use declarativeNetRequest to redirect to a url create by "createObjectURL"?

I try to make an extension to mock json data for some axios.get api.I use the code below to insert a function into page and form a url like "blob:http://xxxx/xxxx'

//in popup.js
const generateUrl=()=>{
      const o = { name: 'test', age: '18' }
        const s = JSON.stringify(o);
        const b = new Blob([s], { type: 'application/json' })
        const u = window.URL.createObjectURL(b);
        chrome.runtime.sendMessage({type:'ENABLE_PROXY', data: u }, (response) => {});
}

chrome.scripting.executeScript({
                    target: { tabId: tab.id },
                    func: generateUrl
})

then I update rules in background.js

//in background.js
const updateRules = (proxyUrl) => {
    const rules = {
        removeRuleIds: [1, 2],
        addRules: [
            {
                id: 1,
                priority: 1,
                condition: {
                    urlFilter: 'your_origin_url_info',
                    resourceTypes: ["xmlhttprequest"],
                },
                action: {
                    type: "redirect",
                    "redirect": { "url": proxyUrl }
                }
            }
        ]
    };
     chrome.declarativeNetRequest.updateDynamicRules(rules, () => {
        chrome.declarativeNetRequest.getDynamicRules(rules => console.log(rules))
    })
}

//listen to msg and upgrade rules
chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
    console.log(msg)
    const {type,data}=msg;
    updateRules(data)
    return true;
})

however it doesn't make sense——I original use 'axios.get('http://127.0.0.1:8881') in a react-app,and it dose redirect the url create by 'createObjectURL' but can't recieve response correctly.

then I tried to send a xhr in chrome-dev-console,it recieved the json object

then I try to modify requestHead and responseHead by declarativeNetRequest,also can't solve this problem.

I notice in blog https://developer.chrome.com/docs/extensions/reference/declarativeNetRequest/#type-ModifyHeaderInfo it says that

I 'm not sure whether that means it is not support to run like my code

how can I use declarativeNetRequest to redirect to a url create by "createObjectURL"?
