使用chrome驱动程序为selenium standalone执行get - Exception抛出

Question

简介

我有selenium独立运行：

curl -XPOST -d'{"capabilities":{"desiredCapabilities":{"browserName":"chrome"}},"desiredCapabilities":{"browserName":"chrome"}}' http://127.0.0.1:4444/wd/hub/session
{"state":null,"sessionId":"d33f687e-62c2-4147-aab1-a1c1bba29aed","hCode":1317400713,"value":{"applicationCacheEnabled":false,"rotatable":false,"networkConnectionEnabled":true,"chrome":{"userDataDir":"/tmp/.com.google.Chrome.w26Qkk"},"takesHeapSnapshot":true,"databaseEnabled":false,"handlesAlerts":true,"hasTouchScreen":true,"version":"57.0.2987.133","platform":"LINUX","browserConnectionEnabled":false,"nativeEvents":true,"acceptSslCerts":true,"webdriver.remote.sessionid":"d33f687e-62c2-4147-aab1-a1c1bba29aed","locationContextEnabled":true,"webStorageEnabled":true,"browserName":"chrome","takesScreenshot":true,"javascriptEnabled":true,"cssSelectorsEnabled":true},"class":"org.openqa.selenium.remote.Response","status":0}

我在同一工作目录中有chromedriver。

我创建了chrome会话：

You are using an unsupported command-line flag: -ignore-certificate-errors. Stability and security will suffer.

我看到Chrome已打开并显示消息：

curl -XPOST -d'{"url":"http://stackoverflow.com"}' http://127.0.0.1:4444/wd/hub/session/d33f687e-62c2-4147-aab1-a1c1bba29aed/url

问题

然后我尝试用chrome打开一个网址：

我得到response

Chrome浏览器会不打开网址。

获取URL命令的Selenium独立输出：

curl -XPOST -d'{"capabilities":{"desiredCapabilities":{"browserName":"firefox"}},"desiredCapabilities":{"browserName":"firefox"}}' http://127.0.0.1:4444/wd/hub/session

使用firefox工作

同样的操作适用于firefox和geckodriver：

curl -XPOST -d'{"url":"http://stackoverflow.com"}' http://127.0.0.1:4444/wd/hub/session/73835d43-d566-4e88-bcab-1f45ff4db129/url

和

google-chrome -version
Google Chrome 57.0.2987.133 

 ./chromedriver -version
Starting ChromeDriver (v2.9.248304) on port 9515

我看到stackoverflow.com在firefox浏览器中打开。

版本

Google Chrome和Chrome驱动程序版本：

        let camera1 = GMSCameraPosition.camera(withLatitude: 45.4654, longitude:9.1859, zoom: 0.0)
        self.mapView = GMSMapView.map(withFrame: cell.mapView.bounds, camera: camera1)

 Alamofire.request(url, method: .post, parameters: nil, encoding: JSONEncoding.default, headers: nil)
        .validate()
        .responseJSON { response in
            switch response.result {
            case .success:
                print(response.result.value!)
                print("Validation Successful")
                let dictResponse = response.result.value as! NSDictionary
                print(dictResponse)
                 let aryRoutes = dictResponse .value(forKey:"routes" ) as! NSArray
                print(aryRoutes)

                var aryOverViewPolyLines :NSArray = []
                aryOverViewPolyLines = aryRoutes .value(forKey: "overview_polyline") as! NSArray
                print(aryOverViewPolyLines)
                let strPoints = (aryOverViewPolyLines.value(forKey: "points") as! NSArray).object(at: 0)
                let polygon = GMSPolygon()
                polygon.path = GMSPath(fromEncodedPath: strPoints as! String)
                print(strPoints)
                let rectangle = GMSPolyline.init(path: polygon.path)
                rectangle.strokeWidth = 2.0
                rectangle.strokeColor = .white
                rectangle.map = self.mapView

                let mapBounds = GMSCoordinateBounds(path: polygon.path!)
                self.mapView.animate(with: GMSCameraUpdate.fit(mapBounds, withPadding: 150.0))



                case .failure(let error):
                print(response.result.value!)
                print(error)
            }
    }

操作系统： Ubuntu 14.04

Answer 1

根据您的堆栈跟踪，您使用的是旧的ChromeDriver 2.9 。但是，根据ChromeDriver downloads page，对于Chrome 57，您应该使用ChromeDriver 2.29。
