如何在Salesforce中从lightning URL中获取参数？

({
    doInit: function(component, event, helper) {
        var urlParams = helper.getUrlParams();
        // 在这里处理获取到的参数
    },
    
    getUrlParams: function() {
        var url = decodeURIComponent(window.location.search.substring(1));
        var params = url.split('&');
        var urlParams = {};
        
        for(var i = 0; i < params.length; i++) {
            var param = params[i].split('=');
            var paramName = param[0];
            var paramValue = param[1];
            urlParams[paramName] = paramValue;
        }
        
        return urlParams;
    }
})
