禁用图像硒谷歌ChromeDriver [英] Disable images in Selenium Google ChromeDriver

问题描述

通过硒和C＃中使用时，它如何在谷歌浏览器做一件禁用图像？

我已经尝试6种方法，没有工作。我甚至试过在这个的StackOverflow的问题，但是我觉得在信息它是过时

• Chrome的驱动程序：V2.2


• Chrome版本：V29。 0.1547.66米


• 硒：V2.35

所有的尝试我做了不会引起异常，它们正常运行，但仍显示图像：

1的尝试：

  ChromeOptions共同=新ChromeOptions（）; 
 co.AddArgument（ - 禁用的图像）; 
 IWebDriver司机=新ChromeDriver（CO）; 
  

尝试2：

  DesiredCapabilities能力= DesiredCapabilities.Chrome（）; 
 capabilities.SetCapability（chrome.switches，新的字符串[1] {禁用的图像}）; 
  

尝试3：

  ChromeOptions共同=新ChromeOptions（）; 
 co.AddAdditionalCapability（chrome.switches，新的字符串[1] {禁用的图像}）; 
  

尝试4：

  VAR照排=新词典<字符串对象>（）; 
 imageSetting.Add（图像，2）; 
&字典LT;字符串对象>内容=新词典<字符串对象>（）; 
 content.Add（profile.default_content_settings，照排）; 
变种首选项=新词典<字符串对象>（）; 
 prefs.Add（首选项，内容）; 
变种选项=新ChromeOptions（）; 
 VAR字段= options.GetType（）getfield命令（additionalCapabilities，BindingFlags.Instance | BindingFlags.NonPublic可）; 
如果（场！= NULL）
 {
 VAR字典= field.GetValue（期权）作为IDictionary的<字符串对象> ;; 
如果（字典！= NULL）
 dict.Add（ChromeOptions.Capability，首选项）; 
} 
  

尝试5：

  ChromeOptions选项=新ChromeOptions（）; 
 options.AddAdditionalCapability（profile.default_content_settings，2）; 
  

尝试6：

 词典<弦乐，对象> contentSettings =新词典<弦乐，对象>（）; 
 contentSettings.Add（图像，2）; 
&字典LT;弦乐，对象>喜好=新词典<弦乐，对象>（）; 
 preferences.Add（profile.default_content_settings，contentSettings）; 
 DesiredCapabilities帽= DesiredCapabilities.Chrome（）; 
 caps.SetCapability（chrome.prefs，喜好）; 
  

解决方案

使用的http://chrome-extension-downloader.com/ 下载的图像块扩展名（的https://chrome.google.com/webstore/detail/block-image/pehaalcefcjfccdpbckoablngfkfgfgj?hl=en-GB ）。扩展功能可以防止图像在第一时间下载。现在，它只是一个使用下面的语句加载它的事：

  VAR选项=新ChromeOptions（）; 
 
 //使用块图像扩展以避免照片下载。 
 options.AddExtension（块image_v1.0.crx）; 
 
变种司机=新ChromeDriver（选件）; 
  

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

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 I've even tried the answer on this StackOverflow question, however I think the info in it is out of date.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 driver: V2.2
• Chrome version: V29.0.1547.66 m
• Selenium: V2.35

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

Attempt 1:

ChromeOptions co = new ChromeOptions();
co.AddArgument("--disable-images");
IWebDriver driver = new ChromeDriver(co);

Attempt 2:

DesiredCapabilities capabilities = DesiredCapabilities.Chrome();
capabilities.SetCapability("chrome.switches", new string[1] { "disable-images" });

Attempt 3:

ChromeOptions co = new ChromeOptions();
co.AddAdditionalCapability("chrome.switches", new string[1] { "disable-images" });

Attempt 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);
}

Attempt 5:

ChromeOptions options = new ChromeOptions();
options.AddAdditionalCapability("profile.default_content_settings", 2);

Attempt 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);

解决方案

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);
