常用JS Hook代码

// Hook eval
(function() {
    var _eval = eval; 
    eval = function() {
        console.log("eval被调用");
        debugger;
        let result = _eval.apply(this, arguments);
        console.log("eval调用结束:::",result);
        return result;
    };
})();

// Hook JSON.stringify
(function() {
    var _JSON_stringify = JSON.stringify;
    JSON.stringify = function() {
        console.log("JSON.stringify被调用:::", arguments);
        debugger;
        let result = _JSON_stringify.apply(this, arguments);
        console.log("JSON.stringify调用结束::::", result);
        return result;
    };
})();

// Hook JSON.parse
(function() {
    var _JSON_parse = JSON.parse;
    JSON.parse = function() {
        console.log("JSON.parse被调用:::", arguments);
        debugger;
        let result = _JSON_parse.apply(this, arguments);
        console.log("JSON.parse调用结束::::", result);
        return result;
    };
})();

// Hook cookie
(function () {
  var v = "";
  Object.defineProperty(document, "cookie", {
    get: function () {
      return v;
    },
    set: function (value) {
      console.log("Cookie设置值:", value);
      debugger;
      v = value;
      return value;
    },
  });
})();

// Hook header
(function (){
  var _setRequestHeader = window.XMLHttpRequest.prototype.setRequestHeader
  window.XMLHttpRequest.prototype.setRequestHeader = function (header, value) {
    if (header.toUpperCase() === 'X-Requested-With'.toUpperCase()) {
      debugger
    }
    return _setRequestHeader.apply(this, arguments)
  }
})()

// ban掉debugger
setInterval = function(){};
setTimeout = function(){};
