从Pinterest网址获取电路板上的所有图像

这个问题听起来很简单,但并不像听起来那么简单。

错误摘要

例如,使用此板; http://pinterest.com/dodo/web-designui-and-mobile/

在页面顶部检查电路板本身的HTML(位于div内的类GridItems)会产生:

<div class="variableHeightLayout padItems GridItems Module centeredWithinWrapper" style="..">
    <!-- First div with a displayed board image -->
    <div class="item" style="top: 0px; left: 0px; visibility: visible;">..</div>
    ...
    <!-- Last div with a displayed board image -->
    <div class="item" style="top: 3343px; left: 1000px; visibility: visible;">..</div>
</div>

然而,在页面底部,在激活无限滚动几次之后,我们将其作为HTML:

<div class="variableHeightLayout padItems GridItems Module centeredWithinWrapper" style="..">
    <!-- First div with a displayed board image -->
    <div class="item" style="top: 12431px; left: 750px; visibility: visible;">..</div>
    ...
    <!-- Last div with a displayed board image -->
    <div class="item" style="top: 19944px; left: 750px; visibility: visible;">..</div>
</div>

正如您所看到的,页面上方图像的某些容器已经消失,并且在首次加载页面时并非所有图像容器都会加载。


我想做什么

我希望能够创建一个可以下载页面完整HTML的C#脚本(或任何服务器端语言)(即检索页面上的每个图像),然后从他们的页面下载图像网址。下载网页并使用适当的XPath很容易,但真正的挑战是为每个图像下载完整的HTML。

有没有办法可以模拟滚动到页面底部,还是有更简单的方法可以检索每个图像?我想Pinterest使用AJAX来改变HTML,有没有办法可以通过编程方式触发事件来接收所有的HTML?提前感谢您的建议和解决方案,并且如果您没有任何建议和解决方案,请立即阅读这个非常长的问题!

伪码

using System;
using System.Net;
using HtmlAgilityPack;

private void Main() {
    string pinterestURL = "http://www.pinterest.com/...";
    string XPath = ".../img";

    HtmlDocument doc = new HtmlDocument();

    // Currently only downloads the first 25 images.
    doc.Load(strPinterestUrl);

    foreach(HtmlNode link in doc.DocumentElement.SelectNodes(strXPath))
    {
         image_links[] = link["src"];
         // Use image links
    }
}

好的,所以我认为这可能(有一些改动)你需要的东西。

<强>注意事项:

  1. 这是PHP,而不是C#(但你说你对任何服务器端语言感兴趣)。
  2. 此代码挂钩(非官方)Pinterest搜索端点。您需要更改$ data和$ search_res以反映适合您的任务的端点(例如BoardFeedResouce)。注意:至少对于搜索,Pinterest目前使用两个端点,一个用于初始页面加载,另一个用于无限滚动操作。每个都有自己预期的参数结构。
  3. Pinterest没有正式的公共API,只要他们改变任何东西,就会发生这种情况,并且没有任何警告。
  4. 您可能会发现pinterestapi.co.uk更容易实施,并且可以接受您正在做的事情。
  5. 我在类下面有一些演示/调试代码,一旦你得到你想要的数据就不应该存在,以及你可能想要改变的默认页面获取限制。
  6. 兴趣点:

    1. 下划线_参数采用JavaScript格式的时间戳,即。像Unix时间,但它添加了毫秒。它实际上并不用于分页。
    2. 分页使用bookmarks属性,因此您向“新”端点发出第一个请求,但不需要它,然后从结果中获取bookmarks并在请求中使用它要获取结果的下一个“页面”,请从这些结果中取bookmarks以获取下一页,然后依此类推,直到您的结果用完或达到预设限制(或者您点击服务器)最大脚本执行时间)。我很想知道bookmarks字段编码的具体内容。我想除了针脚ID或其他页面标记外,还有一些有趣的秘诀。
    3. 我正在跳过html,而不是处理JSON,因为它比使用DOM操作解决方案或一堆正则表达式更容易(对我而言)。

有几个人建议使用javascript来模拟滚动。

我认为你根本不需要模拟滚动,我认为只需要在滚动发生时找出通过AJAX调用的URI的格式,然后你就可以按顺序获得结果的每个“页面”。需要一点落后的工程。

使用Chrome检查器的网络标签我可以看到,一旦我到达页面的某个距离,就会调用此URI:

http://pinterest.com/resource/BoardFeedResource/get/?source_url=%2Fdodo%2Fweb-designui-and-mobile%2F&data=%7B%22options%22%3A%7B%22board_id%22%3A%22158400180582875562%22%2C%22access%22%3A%5B%5D%2C%22bookmarks%22%3A%5B%22LT4xNTg0MDAxMTE4NjcxMTM2ODk6MjV8ZWJjODJjOWI4NTQ4NjU4ZDMyNzhmN2U3MGQyZGJhYTJhZjY2ODUzNTI4YTZhY2NlNmY0M2I1ODYwYjExZmQ3Yw%3D%3D%22%5D%7D%2C%22context%22%3A%7B%22app_version%22%3A%22fb43cdb%22%7D%2C%22module%22%3A%7B%22name%22%3A%22GridItems%22%2C%22options%22%3A%7B%22scrollable%22%3Atrue%2C%22show_grid_footer%22%3Atrue%2C%22centered%22%3Atrue%2C%22reflow_all%22%3Atrue%2C%22virtualize%22%3Atrue%2C%22item_options%22%3A%7B%22show_rich_title%22%3Afalse%2C%22squish_giraffe_pins%22%3Afalse%2C%22show_board%22%3Afalse%2C%22show_via%22%3Afalse%2C%22show_pinner%22%3Afalse%2C%22show_pinned_from%22%3Atrue%7D%2C%22layout%22%3A%22variable_height%22%7D%7D%2C%22append%22%3Atrue%2C%22error_strategy%22%3A1%7D&_=1377092055381

如果我们解码它,我们发现它主要是JSON

        }
    },
    "append": true,
    "error_strategy": 2
}
&_=1377092231234

正如您所看到的,没有太大变化。 Board_id是一样的。 error_strategy现在是2,而最后的&amp; _是不同的。

&amp; _参数在这里是关键。我敢打赌,它告诉页面从哪里开始下一组照片。我无法在任何响应或原始页面HTML中找到它的引用,但它必须在某处,或者在客户端通过javascript生成。无论哪种方式,页面/浏览器都必须知道下一步要求什么,所以这些信息是你应该能够获得的。

答案 2 :(得分:1)

可能有点晚了,但是,使用py3-pinterest开源项目,您可以轻松地做到这一点:

首先从板上获取所有引脚作为对象,它们还包括原始图像URL。

# get all pins for the board
board_pins = []
pin_batch = pinterest.board_feed(board_id=target_board['id'], board_url=target_board['url'])

while len(pin_batch) > 0:
    board_pins += pin_batch
    pin_batch = pinterest.board_feed(board_id=target_board['id'], board_url=target_board['url'])

然后,您可以获取图像URL并下载它们或对它们进行任何操作

for pin in board_pins:
    url = pin['image']
    # process image url..

是的,但是您仍然坚持使用c#吗?应该很容易将其移植:)

您可以通过使用此标头发出请求来触发json端点:X-Requested-With:XMLHttpRequest

在控制台中尝试使用此命令:

curl -H "X-Requested-With:XMLHttpRequest" "http://pinterest.com/resource/CategoryFeedResource/get/?source_url=%2Fall%2Fgeek%2F&data=%7B%22options%22%3A%7B%22feed%22%3A%22geek%22%2C%22scope%22%3Anull%2C%22bookmarks%22%3A%5B%22Pz8xMzc3NjU4MjEyLjc0Xy0xfDE1ZjczYzc4YzNlNDg3M2YyNDQ4NGU1ZTczMmM0ZTQyYzBjMWFiMWNhYjRhMDRhYjg2MTYwMGVkNWQ0ZDg1MTY%3D%22%5D%2C%22is_category_feed%22%3Atrue%7D%2C%22context%22%3A%7B%22app_version%22%3A%22addc92b%22%7D%2C%22module%22%3A%7B%22name%22%3A%22GridItems%22%2C%22options%22%3A%7B%22scrollable%22%3Atrue%2C%22show_grid_footer%22%3Atrue%2C%22centered%22%3Atrue%2C%22reflow_all%22%3Atrue%2C%22virtualize%22%3Atrue%2C%22item_options%22%3A%7B%22show_pinner%22%3Atrue%2C%22show_pinned_from%22%3Afalse%2C%22show_board%22%3Atrue%2C%22show_via%22%3Afalse%7D%2C%22layout%22%3A%22variable_height%22%7D%7D%2C%22append%22%3Atrue%2C%22error_strategy%22%3A2%7D&module_path=App()%3EHeader()%3EDropdownButton()%3EDropdown()%3ECategoriesMenu(resource%3D%5Bobject+Object%5D%2C+name%3DCategoriesMenu%2C+resource%3DCategoriesResource(browsable%3Dtrue))&_=1377658213300" | python -mjson.tool

您将在输出的json中看到引脚数据。您应该能够解析它并获取您需要的下一个图像。

至于这一点:&_=1377658213300。我推测这是前一个列表的最后一个引脚的id。您应该可以使用上一个响应中的最后一个引脚在每次调用时替换它。

## This program may be reutilized without limits, provided this

## If this breaks one day, then just fire up firefox Developer Tools and check the network traffic to 
## capture "copy as curl" of the calls to the search page (filter with BaseSearchResource), then the 
## call to feed more data (filter with SearchResource). 
## 
## Do a search on whatever you want remove the cookie header, and add -o ret2.html -D h2.txt -c c1.txt, 
## then search replace the search terms as SEARCHTOKEN1 and SEARCHTOKEN2. 
## 
## Description this script facilitates alternate browsers, by caching images/pins 
## from pinterest. This script is hardwired for two search terms. First create a directory 
## to where you want the images to go, then cd there. 
##  Usage: 
##    $> cd /big/drive/auto_gyros 
##    $> getpins.bsh "sleek autogyros"
## 
## Expect around 900 images to land wherever you select, so make sure you have space! =)
