Java: 如何使用 Selenium 从亚马逊抓取图片?

Java: How to Scrape Images from Amazon with Selenium?

我正在尝试使用 Selenium WebDriver 从亚马逊上的 URL 抓取页面左侧的 6 张图片:

http://www.amazon.com/EasyAcc%C2%AE-10000mAh-Brilliant-Smartphone-Bluetooth/dp/B00H9BEC8E

但是,无论我尝试什么都会导致错误。到目前为止我尝试了什么:

  1. 我尝试直接使用 XPATH 抓取图像,然后使用 "getAttributes" 方法提取 src。例如,对于页面上的第一个图像,XPATH 是:

    .//*[@id='a-autoid-2']/span/input

所以我尝试了以下方法:

  String path1 = ".//*[@id='a-autoid-2']/span/input";
        String url = "http://www.amazon.com/EasyAcc%C2%AE-10000mAh-Brilliant-Smartphone-Bluetooth/dp/B00H9BEC8E";
        WebDriver driver = new FirefoxDriver();
        driver.get(url);
  WebElement s;
        s = driver.findElement(By.xpath(path1));
        String src;
        src = s.getAttribute("src");
        System.out.println(src);

但是我找不到来源。

注意:仅当从某些类型的产品中抓取图像时才会出现此问题。例如,我可以使用 Selenium 轻松地从该产品中抓取图像:

http://www.amazon.com/Ultimate-Unification-Diet-Health-Disease/dp/0615797806/

import java.util.List;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class mytest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub



        String path = ".//*[@id='imgThumbs']/div[2]/img";

        String url = "http://www.amazon.com/Ultimate-Unification-Diet-Health-Disease/dp/0615797806/";
        WebDriver driver = new FirefoxDriver();
        driver.get(url);


        WebElement s;
        s = driver.findElement(By.xpath(path));
        String src;
        src = s.getAttribute("src");
        System.out.println(src);

        driver.close();


    }
}

此代码完美运行。只是在抓取某些产品时,似乎没有办法解决。

  1. 我尝试单击导致 iframe 打开的图像,但我也无法从该 iframe 中抓取图像,即使在切换到 iframe 后也是如此:

    driver.switchTo().frame(IFRAMEID);

我知道我可以使用 "screenshot" 方法,但我想知道是否有办法直接抓取图像?

谢谢

试试这个代码

    String path = "//div[@id='imageBlock_feature_div']//span/img";

    String url = "http://rads.whosebug.com/amzn/click/0615797806";
    WebDriver driver = new FirefoxDriver();
    driver.get(url);

    List<WebElement> srcs;
    srcs = driver.findElements(By.xpath(path));

    for(WebElement src : srcs) {
        System.out.println(src.getAttribute("src"));
    }

    driver.close();

结果

但是,要获取亚马逊图片,我建议您尝试亚马逊 API https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html

好多了。
