借助：ReplaceGoogleCDN 响应头重写功能，解决跨域问题
缘由：临时起意，想看deno在【微博站点或者微信公众号】中被搜索引擎收录情况,并且把结果显示在指定站点
关键点： 解决不同站点之间的跨域问题
例子总共分三步：
-- 步骤一： 添加自定义规则
-- 步骤二： 打开站点 https://www.jingjingxyk.com/ 页面下的web控制台，并执行下面的脚本
-- 步骤三：观察控制台结果（发现，跨域已经被解决）
步骤一： 自定义规则例子：
关键点： 设置
access-control-allow-origin,最宽泛的是设置为*，当然也可以设置为指定的站点地址
{
"action": {
"requestHeaders": [
{
"header": "referer",
"operation": "set",
"value": "https://www.baidu.com"
},
{
"header": "origin",
"operation": "set",
"value": "https://www.baidu.com"
}
],
"responseHeaders": [
{
"header": "access-control-allow-origin",
"operation": "set",
"value": "*"
},
{
"header": "set-cookie",
"operation": "remove"
}
],
"type": "modifyHeaders"
},
"condition": {
"initiatorDomains": [
"justjavac.com",
"jingingxyk.com"
],
"requestDomains": [
"www.baidu.com"
],
"resourceTypes": [
"main_frame",
"sub_frame",
"stylesheet",
"script",
"image",
"font",
"object",
"xmlhttprequest",
"ping",
"csp_report",
"media",
"websocket",
"webtransport",
"webbundle",
"other"
],
"urlFilter": "https://www.baidu.com/s?ie=utf-8&wd=*"
},
"id": 20015,
"priority": 10
}
步骤二： web控制台执行如下代码
{
//let url='https://www.baidu.com/s?ie=utf-8&wd=deno%20site%3A%20weibo.com'
let url='https://www.baidu.com/s?ie=utf-8&wd=deno%20site%3Amp.weixin.qq.com'
fetch(url).then(res=>res.text()).then((res)=>{
let content=(new DOMParser()).parseFromString(res,'text/html').body
console.log(content)
})
}
