How to use WebMapServiceImageryProvider or UrlTemplateImageryProvider with authentication token

CesiumJS

Thanks for your reply. It helped to direct me to the right path :wink:

I ended up just patching the “fetch” function of the Resource class:

    /**
     * Patches the original Cesium.Resource class to allow updating of authorization header in HTTP requests.
     */
    private patchCesiumResource(): void {
        const orig = Cesium.Resource.prototype.fetch;

        // Store reference to the service, because "this" refers to the resource instance inside the patched function.
        const self = this;

        Cesium.Resource.prototype.fetch = function(callOptions: any) {
            if (this.headers.Authorization === 'system') {
                this.headers.Authorization = self.authentication;
            }

            return orig.call(this, callOptions);
        };
    }
