C#中通过Selenium IWebDriver实现人人网相册备份工具

我用Selenium写了一个人人网相册备份工具，亲测通过。

需要输入你的用户名、密码、相册地址。

代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Interactions;
using OpenQA.Selenium.Support.UI;
using System.Threading;
using System.IO;
using System.Net;

namespace RenrenBackup
{
public class Program
{
static void Main(string[] args)
{
//Configuration.
Program pp = new Program();
string url = "http://www.renren.com";
string userName = "";
string pwd = "";
string albumUrl = "";
//Start backup.
IWebDriver iw = new InternetExplorerDriver();
iw = pp.Login(url, pwd, userName, iw);
iw.Navigate().GoToUrl(albumUrl);
pp.WaitUntilPageLoadedID(iw, "c-b-describe");
List<string> photoUrls = new List<string>();
var photos = iw.FindElements(By.ClassName("photo-box"));
var count = iw.FindElement(By.Id("album-count")).Text;
while (photos.Count() != Int32.Parse(count))
{
try
{
String setScroll = "document.documentElement.scrollTop=" + 9000;
((IJavaScriptExecutor)iw).ExecuteScript(setScroll);
Thread.Sleep(3000);
photos = iw.FindElements(By.ClassName("photo-box"));
}
catch (Exception ex)
{
WriteLog(ex);
}
}
string value;
for (int i = 0; i < photos.Count(); i++)
{
value = iw.FindElements(By.XPath("//a/img[@class='p-b-item']"))[i].GetAttribute("data-viewer");
value = value.Split(',')[4].Split('"')[3].Trim();
photoUrls.Add(value);
}
pp.WriteToFile(photoUrls);
string filePath;
string folderPath = @Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + @"\" + iw.FindElement(By.Id("album-name")).Text;
if (!Directory.Exists(folderPath))
{
Directory.CreateDirectory(folderPath);
}
for (int i = 0; i < photoUrls.Count(); i++)
{
filePath = folderPath + @"\" + i + "pic.jpg";
WebClient myWebClient = new WebClient();
try
{
myWebClient.DownloadFile(photoUrls[i], filePath);
}
catch (Exception ex)
{
WriteLog(ex);
}
}
}

public void WriteToFile(List<string> photoUrls)
{

if (File.Exists(file))
{
using (StreamWriter sw = new StreamWriter(file, true))
{

using (StreamWriter sw = new StreamWriter(file, true))
{

sw.Flush();

}
}
}

public void WriteToFile(string v)

}
public void WaitUntilPageLoadedID(IWebDriver iw, string id)
{

{
iw.FindElement(By.Id(id));
}
catch (Exception ex)
{
Console.WriteLine(ex);
Thread.Sleep(2000);
WaitUntilPageLoadedID(iw, id);
}
}

{

iw.FindElement(By.XPath(v));
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
Thread.Sleep(1000);
WaitUntilPageLoadedXPath(iw, v);
}
}

private static void WriteLog(Exception ex)
{
string logUrl = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + "\\DownloadLog.txt";
if (File.Exists(@logUrl))
{
using (FileStream fs = new FileStream(logUrl, FileMode.Append))
{
using (StreamWriter sw = new StreamWriter(fs, Encoding.Default))

fs.Close();

{
sw.Close();
fs.Close();
}
}
}
}
}
}
}

引用如下：



注意设置IEDriverServer.exe的属性为“Copy aLways”。

运行后会在桌面生成一个和你人人网相册同名的文件夹，下面保存的是你的相册相片。桌面还会有下载的图片的详细url列表以及如果有异常会产生的log文件。

OK，回家。
