# DHTSpider
>A Very Simple Spider With DHT Crawler, Written by C#.
* The bittorrent library bases on DhtWalker,MonoTorrent.
* The bittorrent library bases on MonoTorrent.
## 介绍
### 介绍
DHTSpider 是一个由C#编写的 DHT 爬虫, 从全球` DHT ` 网络里"`嗅探`"正在下载的资源, 并把资源`metadata`(种子信息)进行抓取下载.
## 相关
### 相关
使用 `MongoDB` 进行数据存储.
>Cache
使用 `ElasticSearch` 进行全文检索(待定).
+ 使用 `Memory` > UseDefaultCache ( 默认 )
+ 使用 `Redis` > UseRedisCache ( TODO )
>Queue
## 环境
+ 使用 `Memory` > UseDefaultQueue ( 默认 )
+ 使用 `Redis` > UseRedisQueue ( TODO )
>Store
+ 使用 `MongoDB` > UseMongoDBStore ( TODO )
+ 使用 `ElasticSearch` > UseElasticSearchStore ( TODO )
>Log > `NLog`
>Ioc > `Autofac`
### 环境
1. `.net` 版本 `>=4.5.2`
2. 运行的机器需要`独立IP` , 能够访问外网 ( `翻墙` )
2. 运行的机器需要`独立IP` , 内网机器需要做下`端口映射`
## 参数
### 使用
```c#
var spider = SpiderConfiguration.Create() //使用默认配置
.UseDefaultCache() //默认使用内存缓存
.UseDefaultQueue() //默认使用内存队列
.Start();
```
Setting.InitSetting();//初始化相关参数
```
```
### 配置
```c#
LocalPort = 6881;
IsSaveTorrent = true;
TorrentSavePath = @"torrent\";
IsUsingMongoDb = false;
InitResolverThreadCount = 10;
MaxResolverThreadCount = 50;
WaitSeedsCount = 100;
//DhtSpiderSetting
DhtSpiderSetting.MaxSendQueue = 50;
DhtSpiderSetting.MaxFindSendPer = 100;
DhtSpiderSetting.MaxWaitCount = 1000;
DhtSpiderSetting.MaxCacheCount = 5000;
var spider = SpiderConfiguration.Create(new SpiderSetting()
{
LocalPort = 6881, //使用端口
IsSaveTorrent = true, //是否保存torrent
TorrentSavePath = "", //torrent保存路径
MaxSpiderThreadCount = 1, //爬虫线程数
MaxDownLoadThreadCount = 20 //下载线程数
})
.UseRedisCache() //使用redis缓存
.UseRedisQueue() //使用redis队列
.UseMongoDBStore() //使用mongodb存储
.Start();
```
## 感谢
项目开发中,`bittorrent`相关类库参考了 `DhtWalker` 和 `MonoTorrent`, 在此感谢作者 →_→
