Question

尝试使用Google地图的API时出现script-src 'unsafe-eval'错误。

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>

这是控制台错误：

Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' ' *.gstatic.com *.googleapis.com *.google-analytics.com *.google.com".

您会认为Google的库中不会有任何不安全的eval触发器。如果它可能是我的一面，我的代码如下：

JS

function initialize() {
    // Create the map.

    var mapOptions = {
        zoom: 4,
        center: new google.maps.LatLng(37.09024, -95.712891),
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        zoomControl: true,
        streetViewControl: false
    };

    var map = new google.maps.Map(document.getElementById('map-canvas'),
        mapOptions);

    google.maps.event.addListener(map, "click", function (e) {

        var marker = new google.maps.Marker({
              draggable: true,
              raiseOnDrag: false,
              map: map,
              position: e.latLng
        });

        var radius = Math.pow(2, (20 - map.getZoom())) * 3;
        if (radius < 100) {
            radius = 100;
        }

        var circle = new google.maps.Circle({
            map: map,
            editable: true,
            radius: radius,
            fillColor: '#0159e5',
            strokeColor: '#0159e5',
            strokeWeight: 1,
            geodesic: true
        });

        circle.bindTo('center', marker, 'position');

        google.maps.event.addListener(circle, 'radius_changed', function() {
            if (circle.getRadius() < 100){
                circle.setRadius(100);
            }
        });

        //Set form fields
        document.getElementById("geo-fence-lat").value = marker.getPosition().lat();
        document.getElementById("geo-fence-long").value = marker.getPosition().lng();
        document.getElementById("geo-fence-radius").value = Math.ceil(radius/100)*100;

        google.maps.event.clearListeners(map, "click");

        addListeners(circle);
    });


}

对GMaps替代品的任何修复或想法将不胜感激。

编辑：这些是Chrome中的违规行。在maps.gstatic.com maps-api-v3 / api / js / 21/2 / main.js中找到。

Kh.main = function(a) {
    eval(a)
};
fg("main", {});

function ql(a) {
    return O(eval, k, "window." + a + "()")
}

在Google Maps 3.23中看起来主要已修复 - 请参阅issue 4201

代码中仍然存在eval的一些实例 - 例如eval('document.namespaces')块内的try（请参阅：related Closure fix）

使用Google Maps API的CSP unsafe-eval
