问题描述

在哪里Chrome浏览器保存主页或启动页面的网址?我想以编程方式访问它使用C#。


解决方案

  

默认位置为:


  
  

的Windows XP


  
  

谷歌浏览器: C:\\ Documents和Settings \\<用户名> \\本地设置\\应用数据\\谷歌\\铬\\用户数据\\默认结果
  铬: C:\\ Documents和Settings \\<用户名> \\本地设置\\应用数据\\铬\\用户数据\\默认


  
  

Vista / 7的


  
  

谷歌浏览器: C:\\用户\\<用户名> \\应用程序数据\\本地\\谷歌\\铬\\用户数据\\默认

  铬: C:\\用户\\<用户名> \\应用程序数据\\本地\\铬\\用户数据\\默认


  
  

的Mac OS X


  
  

谷歌浏览器: 〜/库/ Application Support /谷歌/铬/默认结果
  铬: 〜/库/ Application Support /铬/默认


  
  

的Linux


  
  

谷歌浏览器: 〜/ .config文件/谷歌铬/默认结果
  铬: 〜/ .config文件/铬/默认


来源:谷歌铬用户数据目录默认位置。 (链接

在的时候,我在写这个花了多少,这是我能想到的(我完全忽略了一个事实,即用户可以使用不同的位置,然后默认)最短和最强大的例子。必须说,这是有点麻烦,那么我想。

在这个例子中,我尝试使用默认位置目录,并且发现,其中的主页被存储在preference文件。它存储在 JSON格式的,所以我反序列化,我很感兴趣的数据,并打印出来。

Win 7的示例:

 使用系统;
使用System.Collections.Generic;
使用System.Linq的;
使用System.Text;
使用System.IO;
//参考 - >添加引用 - > System.Runtime.Serialization添加
使用System.Runtime.Serialization;
使用System.Runtime.Serialization.Json;命名空间测试{
    类节目{
        [DataContract]
        公共类MDATA {
            [数据成员(NAME =主页)]
            公共字符串的主页{搞定;私人集; }
            [数据成员(NAME =homepage_is_newtabpage)]
            公共布尔isNewTab {搞定;私人集; }
            公共MDATA(){}
            公共MDATA(字符串数据){
                首页=数据;
            }
        }        公共静态MDATA FindData(JSON字符串){
            MDATA deserializedData =新MDATA();
            MemoryStream的毫秒=新的MemoryStream(Encoding.UTF8.GetBytes(JSON));
            DataContractJsonSerializer SER =新DataContractJsonSerializer(deserializedData.GetType());
            deserializedData = ser.ReadObject(毫秒),为MDATA;
            ms.Close();
            返回deserializedData;
        }        静态无效的主要(字串[] args){
            const int的LikeWin7 = 6;
            OperatingSystem的OSINFO = Environment.OSVersion;
            DirectoryInfo的strDirectory;
            路径字符串=空,文件= NULL,数据;            如果(osInfo.Platform.Equals(System.PlatformID.Win32NT))
                如果(osInfo.Version.Major == LikeWin7)
                    PATH = Environment.GetEnvironmentVariable(LOCALAPPDATA)+
                        @\\谷歌\\铬\\用户数据\\默认;
            如果(路径== NULL || path.Length == 0)
                抛出新的ArgumentNullException(故障坏的操作系统。);
            如果(!(strDirectory =新DirectoryInfo的(路径))。存在)
                抛出新DirectoryNotFoundException(故障目录没有资金。);
            如果(!新的FileInfo(文件= Directory.GetFiles(strDirectory.FullName,preferences *)[0])。存在)
                抛出新的FileNotFoundException异常(失败的文件没有被发现。文件);            MDATA信息= FindData(数据= System.IO.File.ReadAllText(文件));
            Console.WriteLine(info.homepage);
            Console.WriteLine(info.isNewTab);
        }
    }
}

输出示例对我来说:

 镀铬:// newtab
真正

我希望至少获得1票起来:P

Where does Chrome save the Home or Start page URL? I want to access it programmatically using C#.

解决方案

Default locations are:

Windows XP

Google Chrome: C:\Documents and Settings\<username>\Local Settings\Application Data\Google\Chrome\User Data\Default
Chromium: C:\Documents and Settings\<username>\Local Settings\Application Data\Chromium\User Data\Default

Vista / 7

Google Chrome: C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default
Chromium: C:\Users\<username>\AppData\Local\Chromium\User Data\Default

Mac OS X

Google Chrome: ~/Library/Application Support/Google/Chrome/Default
Chromium: ~/Library/Application Support/Chromium/Default

Linux

Google Chrome: ~/.config/google-chrome/Default
Chromium: ~/.config/chromium/Default

Source: Google Chromium user data directory default locations. ( link )

In amount of time I spent on writing this, this was the shortest and most robust example I could think of (I completely ignored the fact, that user could use different location then default). Must say, it was bit trickier, then I thought.

In this example, I try using the default location directory, and finding the preference file where the "Home" is stored. It is stored in JSon format, so I deserialize the data that I am interested, and print it out.

Win 7 Example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
//References -> Add Reference -> "System.Runtime.Serialization" Add
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;

namespace test {
    class Program {
        [DataContract]
        public class Mdata {
            [DataMember(Name = "homepage")] 
            public String homepage { get; private set; }
            [DataMember(Name = "homepage_is_newtabpage")]
            public Boolean isNewTab { get; private set; }
            public Mdata() { }
            public Mdata(String data) {
                homepage = data;
            }
        }

        public static Mdata FindData(String json) {
            Mdata deserializedData = new Mdata();
            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json));
            DataContractJsonSerializer ser = new DataContractJsonSerializer(deserializedData.GetType());
            deserializedData = ser.ReadObject(ms) as Mdata;
            ms.Close();
            return deserializedData;
        }

        static void Main(string[] args) {
            const int LikeWin7 = 6;
            OperatingSystem osInfo = Environment.OSVersion;
            DirectoryInfo strDirectory;
            String path=null, file=null, data;

            if (osInfo.Platform.Equals(System.PlatformID.Win32NT))
                if (osInfo.Version.Major == LikeWin7)
                    path = Environment.GetEnvironmentVariable("LocalAppData") +
                        @"\Google\Chrome\User Data\Default";
            if (path == null || path.Length == 0)
                throw new ArgumentNullException("Fail. Bad OS.");
            if (!(strDirectory = new DirectoryInfo(path)).Exists)
                throw new DirectoryNotFoundException("Fail. The directory was not fund");
            if (!new FileInfo(file = Directory.GetFiles(strDirectory.FullName, "Preferences*")[0]).Exists)
                throw new FileNotFoundException("Fail. The file was not found.", file);

            Mdata info = FindData(data = System.IO.File.ReadAllText(file));
            Console.WriteLine(info.homepage);
            Console.WriteLine(info.isNewTab);
        }
    }
}

Example output for Me:

chrome://newtab
True
