使用chromedriver获取硒中的图像源

Question

我正在使用C＃中的Selenium Webdriver，并尝试使用GetProperty方法获取图像的src，以验证是否显示了正确的图像。

var productImg = product.FindElement(By.TagName("img"));
var productSrc = productImg.GetProperty("src");

使用firefox运行时，我得到的图像源如下：

"https://s7d7.scene7.com/is/image/GTMSportswear/?fmt=png-alpha&hei=184&wid=184&bgc=ffffff&GTM_Group=1&layer=0&resMode=sharp2&src=ir(GTMSportswearRender/U118TL-Century?obj=Layer1&req=object&decal&show&src=is(GTMSportswear/$Zone1$))&$Zone1=Sub_Gold&GTM_Group=2&layer=1&resMode=sharp2&src=ir(GTMSportswearRender/U118TL-Century?obj=GraphicBody&req=object&decal&anchor=750,0&show&src=is(GTMSportswear/$Zone2$?src=is(GTMSportswear/U118TL-Century-1A)))&$Zone2=Sub_White&GTM_Group=3&layer=2&resMode=sharp2&src=ir(GTMSportswearRender/U118TL-Century?obj=GraphicBody&req=object&decal&anchor=750,0&show&src=is(GTMSportswear/$Zone3$?src=is(GTMSportswear/U118TL-Century-1B)))&$Zone3=Sub_Silver&GTM_Group=4&layer=3&resMode=sharp2&src=ir(GTMSportswearRender/U118TL-Century?obj=GraphicBody&req=object&decal&anchor=750,0&show&src=is(GTMSportswear/$Zone4$?src=is(GTMSportswear/U118TL-Century-1C)))&$Zone4=Sub_Black&GTM_Group=5&layer=4&resMode=sharp2&src=ir(GTMSportswearRender/U118TL-Century?obj=Binding&req=object&decal&show&src=is(GTMSportswear/$Zone5$))&$Zone5=Sub_White&GTM_Group=6&layer=5&resMode=sharp2&src=ir(GTMSportswearRender/U118TL-Century?obj=Inside&req=object&decal&show&src=is(GTMSportswear/Sub_Silver))"

哪个是正确的图像源。

当使用firefox运行此程序时，一切都按预期方式工作，尽管当我使用chromedriver运行此程序时，GetProperty收到一个空引用异常。 调试productImg时，似乎与chromedriver和firefox驱动程序完全相同。 谷歌搜索并环顾四周，在这里我看不到其他人遇到同样的问题。

为方便起见，周围的html：

 <div class="productCard"> <figure> <img src="https://s7d7.scene7.com/is/image/GTMSportswear/?fmt=png-alpha&amp;hei=184&amp;wid=184&amp;bgc=ffffff&amp;GTM_Group=1&amp;layer=0&amp;resMode=sharp2&amp;src=ir(GTMSportswearRender/U118TL-Century?obj=Layer1&amp;req=object&amp;decal&amp;show&amp;src=is(GTMSportswear/$Zone1$))&amp;$Zone1=Sub_Gold&amp;GTM_Group=2&amp;layer=1&amp;resMode=sharp2&amp;src=ir(GTMSportswearRender/U118TL-Century?obj=GraphicBody&amp;req=object&amp;decal&amp;anchor=750,0&amp;show&amp;src=is(GTMSportswear/$Zone2$?src=is(GTMSportswear/U118TL-Century-1A)))&amp;$Zone2=Sub_White&amp;GTM_Group=3&amp;layer=2&amp;resMode=sharp2&amp;src=ir(GTMSportswearRender/U118TL-Century?obj=GraphicBody&amp;req=object&amp;decal&amp;anchor=750,0&amp;show&amp;src=is(GTMSportswear/$Zone3$?src=is(GTMSportswear/U118TL-Century-1B)))&amp;$Zone3=Sub_Silver&amp;GTM_Group=4&amp;layer=3&amp;resMode=sharp2&amp;src=ir(GTMSportswearRender/U118TL-Century?obj=GraphicBody&amp;req=object&amp;decal&amp;anchor=750,0&amp;show&amp;src=is(GTMSportswear/$Zone4$?src=is(GTMSportswear/U118TL-Century-1C)))&amp;$Zone4=Sub_Black&amp;GTM_Group=5&amp;layer=4&amp;resMode=sharp2&amp;src=ir(GTMSportswearRender/U118TL-Century?obj=Binding&amp;req=object&amp;decal&amp;show&amp;src=is(GTMSportswear/$Zone5$))&amp;$Zone5=Sub_White&amp;GTM_Group=6&amp;layer=5&amp;resMode=sharp2&amp;src=ir(GTMSportswearRender/U118TL-Century?obj=Inside&amp;req=object&amp;decal&amp;show&amp;src=is(GTMSportswear/Sub_Silver))" alt="GTM Century UltraFuse SpiritFlex V-Neck Shell"> <figcaption><b>GTM Century UltraFuse SpiritFlex V-Neck Shell</b></figcaption> <p class="productCard__options"> Cuts: Women's, Girls<br> More Colors Available </p> </figure> <div class="productCard__pricing"> <span class="productCard__pricing__price">$50.00</span> <br> <span>Price Includes Art</span> <br> </div> <div class="productCard__rating"> <span class="icon star"></span><span class="icon star"></span><span class="icon star"></span><span class="icon star"></span><span class="icon star empty"></span> </div> <p class="productCard__banner"></p> </div> 

Answer 1

var productImg = dr.FindElement(By.TagName("img"));
var productSrc = productImg.GetAttribute("src");

试试上面的代码：
