在Selenium Google ChromeDriver中禁用图像
通过Selenium和c#使用图像时,如何禁用Google chrome中的图像?
我尝试了6种方法,但均无效果。
- Chrome驱动程序:V2.2
- Chrome版本:V29.0.1547.66 m
- selenium:V2.35
我所做的所有尝试都不会引起异常,它们可以正常运行,但仍显示图像:
尝试1:
ChromeOptions co = new ChromeOptions();co.AddArgument("--disable-images");
IWebDriver driver = new ChromeDriver(co);
尝试2:
DesiredCapabilities capabilities = DesiredCapabilities.Chrome();capabilities.SetCapability("chrome.switches", new string[1] { "disable-images" });
尝试3:
ChromeOptions co = new ChromeOptions();co.AddAdditionalCapability("chrome.switches", new string[1] { "disable-images" });
尝试4:
var imageSetting = new Dictionary<string, object>();imageSetting.Add("images", 2);
Dictionary<string, object> content = new Dictionary<string, object>();
content.Add("profile.default_content_settings", imageSetting);
var prefs = new Dictionary<string, object>();
prefs.Add("prefs", content);
var options = new ChromeOptions();
var field = options.GetType().GetField("additionalCapabilities", BindingFlags.Instance | BindingFlags.NonPublic);
if (field != null)
{
var dict = field.GetValue(options) as IDictionary<string, object>;
if (dict != null)
dict.Add(ChromeOptions.Capability, prefs);
}
尝试5:
ChromeOptions options = new ChromeOptions();options.AddAdditionalCapability("profile.default_content_settings", 2);
尝试6:
Dictionary<String, Object> contentSettings = new Dictionary<String, Object>();contentSettings.Add("images", 2);
Dictionary<String, Object> preferences = new Dictionary<String, Object>();
preferences.Add("profile.default_content_settings", contentSettings);
DesiredCapabilities caps = DesiredCapabilities.Chrome();
caps.SetCapability("chrome.prefs", preferences);
回答:
使用http://chrome-extension-downloader.com/下载“阻止图片”扩展程序(https://chrome.google.com/webstore/detail/block-
image/pehaalcefcjfccdpbckoablngfkfgfgj?hl=zh-
CN)。该扩展名可防止首先下载图像。现在,只需使用以下语句加载它即可:
var options = new ChromeOptions(); //use the block image extension to prevent images from downloading.
options.AddExtension("Block-image_v1.0.crx");
var driver = new ChromeDriver(options);
