如何在通过 Selenium 和 c# 使用 Google chrome 时禁用图像?

How does one disable images in Google chrome when using it through Selenium and c#?

我尝试了 6 种方法，但都没有奏效.我什至尝试过 this StackOverflow 问题的答案，但我认为信息在它已经过时了.

I've attempted 6 ways and none worked. I've even tried the answer on this StackOverflow question, however I think the info in it is out of date.

• Chrome 驱动程序:V2.2
• Chrome 版本:V29.0.1547.66 m
• 硒:V2.35

我所做的所有尝试都不会导致异常，它们运行正常但仍然显示图像:

All the attempts I've made don't cause exceptions, they run normally but still display images:

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);

推荐答案

使用http://chrome-extension-downloader.com/ 下载阻止图像"扩展程序 (https://chrome.google.com/webstore/detail/block-image/pehaalcefcjfccdpbckoablngfkfgfgj?hl=en-GB).该扩展程序首先防止图像被下载.现在只需使用以下语句加载它:

Use http://chrome-extension-downloader.com/ to download the "Block Image" extension (https://chrome.google.com/webstore/detail/block-image/pehaalcefcjfccdpbckoablngfkfgfgj?hl=en-GB). The extension prevents the image from being downloaded in the first place. Now it's just a matter of loading it using the following statement:

    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);
