【记录】补环境代理（Proxy）方法

js代码

function getEnvs(proxyObjs) {
    for (let i = 0; i < proxyObjs.length; i++) {
        const handler = `{
      get: function(target, property, receiver) {
        console.log("方法:", "get  ", "对象:", "${proxyObjs[i]}", "  属性:", property, "  属性类型：", typeof property, ", 属性值：", target[property], ", 属性值类型：", typeof target[property]);
        return target[property];
      },
      set: function(target, property, value, receiver) {
        console.log("方法:", "set  ", "对象:", "${proxyObjs[i]}", "  属性:", property, "  属性类型：", typeof property, ", 属性值：", value, ", 属性值类型：", typeof target[property]);
        return Reflect.set(...arguments);
      }
    }`;
        eval(`try {
            ${proxyObjs[i]};
            ${proxyObjs[i]} = new Proxy(${proxyObjs[i]}, ${handler});
        } catch (e) {
            ${proxyObjs[i]} = {};
            ${proxyObjs[i]} = new Proxy(${proxyObjs[i]}, ${handler});
        }`);
    }
}
proxyObjs = ['window', 'document', 'location', 'navigator', 'history', 'screen']
getEnvs(proxyObjs);

使用：

报错确实localhost的host，直接补这个

location = {
    "host": 'xxxx',
}

结果：

成功生成sign的值

jsdom补环境

const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const dom = new JSDOM('<!DOCUMENT html><p>Test</p>')
window = dom.window
document = window.document
navigator= window.navigator
