with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

WebMagic in Action
========
WebMagic是一个简单灵活、便于二次开发的爬虫框架。除了可以便捷的实现一个爬虫，WebMagic还提供多线程功能，以及基本的分布式功能。
你可以直接使用WebMagic进行爬虫开发，也可以定制WebMagic以适应复杂项目的需要。
## 1. 在项目中使用WebMagic
WebMagic主要包含两个jar包：`webmagic-core-{version}.jar`和`webmagic-extension-{version}.jar`。在项目中添加这两个包的依赖，即可使用WebMagic。
### 1.1 使用Maven
WebMagic基于Maven进行构建，推荐使用Maven来安装WebMagic。在项目中添加以下坐标即可：
```xml
<dependency>
<groupId>us.codecraft</groupId>
<artifactId>webmagic-extension</artifactId>
<version>0.4.3</version>
</dependency>
```
WebMagic使用slf4j-log4j12作为slf4j的实现.如果你自己定制了slf4j的实现，请在项目中去掉此依赖。
```xml
<dependency>
<groupId>us.codecraft</groupId>
<artifactId>webmagic-extension</artifactId>
<version>0.4.3</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>
```
### 1.2 不使用Maven
不使用maven的用户，可以下载附带二进制jar包的版本(感谢[oschina](http://www.oschina.net/))：
git clone http://git.oschina.net/flashsword20/webmagic.git
在**lib**目录下，有项目依赖的所有jar包，直接在IDE里，将这些jar添加到Libraries即可。
![import jars](http://static.oschina.net/uploads/space/2014/0403/143318_gBQE_190591.jpeg)
### 1.3 第一个项目
在你的项目中添加了WebMagic的依赖之后，即可开始第一个爬虫的开发了！我们这里拿一个抓取Github信息的例子：
```java
import us.codecraft.webmagic.Page;
import us.codecraft.webmagic.Site;
import us.codecraft.webmagic.Spider;
import us.codecraft.webmagic.processor.PageProcessor;
public class GithubRepoPageProcessor implements PageProcessor {
private Site site = Site.me().setRetryTimes(3).setSleepTime(100);
@Override
public void process(Page page) {
page.addTargetRequests(page.getHtml().links().regex("(https://github\\.com/\\w+/\\w+)").all());
page.putField("author", page.getUrl().regex("https://github\\.com/(\\w+)/.*").toString());
page.putField("name", page.getHtml().xpath("//h1[@class='entry-title public']/strong/a/text()").toString());
if (page.getResultItems().get("name")==null){
//skip this page
page.setSkip(true);
}
page.putField("readme", page.getHtml().xpath("//div[@id='readme']/tidyText()"));
}
@Override
public Site getSite() {
return site;
}
public static void main(String[] args) {
Spider.create(new GithubRepoPageProcessor()).addUrl("https://github.com/code4craft").thread(5).run();
}
}
```
点击main方法，选择“运行”，你会发现爬虫已经可以正常工作了！

<div style="page-break-after:always"></div>
## 2.下载和编译源码
WebMagic是一个纯Java项目，如果你熟悉Maven，那么下载并编译源码是非常简单的。如果不熟悉Maven也没关系，这部分会介绍如何在Eclipse里导入这个项目。
### 2.1 下载源码
WebMagic目前有两个仓库：
* [https://github.com/code4craft/webmagic](https://github.com/code4craft/webmagic)
github上的仓库保存最新版本，所有issue、pull request都在这里。大家觉得项目不错的话别忘了去给个star哦！
* [http://git.oschina.net/flashsword20/webmagic](http://git.oschina.net/flashsword20/webmagic)
此仓库包含所有编译好的依赖包，只保存项目的稳定版本，最新版本仍在github上更新。oschina在国内比较稳定，主要作为镜像。
无论在哪个仓库，使用
git clone https://github.com/code4craft/webmagic.git
或者
git clone http://git.oschina.net/flashsword20/webmagic.git
即可下载最新代码。
如果你对git本身使用也不熟悉，建议看看@黄勇的 [从 Git@OSC 下载 Smart 源码](http://my.oschina.net/huangyong/blog/200075)
### 2.2 导入项目
Intellij Idea默认自带Maven支持，import项目时选择Maven项目即可。
#### 2.2.1 使用m2e插件
使用Eclipse的用户，推荐安装m2e插件，安装地址：https://www.eclipse.org/m2e/download/[](https://www.eclipse.org/m2e/download/)
安装后，在File->Import中选择Maven->Existing Maven Projects即可导入项目。
![m2e-import](http://static.oschina.net/uploads/space/2014/0403/104427_eNuc_190591.png)
导入后看到项目选择界面，点击finish即可。
![m2e-import2](http://static.oschina.net/uploads/space/2014/0403/104735_6vwG_190591.png)
#### 2.2.2 使用Maven Eclipse插件
如果没有安装m2e插件，只要你安装了Maven，也是比较好办的。在项目根目录下使用命令：
mvn eclipse:eclipse
生成maven项目结构的eclipse配置文件，然后在File->Import中选择General->Existing Projects into Workspace即可导入项目。
![eclipse-import-1](http://static.oschina.net/uploads/space/2014/0403/100025_DAcy_190591.png)
导入后看到项目选择界面，点击finish即可。
![eclipse-import-2](http://static.oschina.net/uploads/space/2014/0403/100227_73DJ_190591.png)
### 2.3 编译和执行源码
导入成功之后，应该就没有编译错误了！此时你可以运行一下webmagic-core项目中自带的exmaple:"us.codecraft.webmagic.processor.example.GithubRepoPageProcessor"。
同样，看到控制台输出如下，则表示源码编译和执行成功了！
![runlog](http://static.oschina.net/uploads/space/2014/0403/103741_3Gf5_190591.png)
<div style="page-break-after:always"></div>
## 3. 基本的爬虫
### 3.1 实现PageProcessor
在WebMagic里，实现一个基本的爬虫只需要编写一个类，实现`PageProcessor`接口即可。这个类基本上包含了抓取一个网站，你需要写的所有代码。
以之前的`GithubRepoPageProcessor`为例，我将PageProcessor的定制分为三个部分，分别是爬虫的配置、页面元素的抽取和链接的发现。
```java
public class GithubRepoPageProcessor implements PageProcessor {
// 部分一：抓取网站的相关配置，包括编码、抓取间隔、重试次数等
private Site site = Site.me().setRetryTimes(3).setSleepTime(1000);
@Override
// process是定制爬虫逻辑的核心接口，在这里编写抽取逻辑
public void process(Page page) {
// 部分二：定义如何抽取页面信息，并保存下来
page.putField("author", page.getUrl().regex("https://github\\.com/(\\w+)/.*").toString());
page.putField("name", page.getHtml().xpath("//h1[@class='entry-title public']/strong/a/text()").toString());
if (page.getResultItems().get("name") == null) {
//skip this page
page.setSkip(true);
}
page.putField("readme", page.getHtml().xpath("//div[@id='readme']/tidyText()"));
// 部分三：从页面发现后续的url地址来抓取
page.addTargetRequests(page.getHtml().links().regex("(https://github\\.com/\\w+/\\w+)").all());
}
@Override
public Site getSite() {
return site;
}
public static void main(String[] args) {
Spider.create(new GithubRepoPageProcessor())
//从"https://github.com/code4craft"开始抓
.addUrl("https://github.com/code4craft")
//开启5个线程抓取
.thread(5)
//启动爬虫
.run();
}
}
```
#### 3.1.1 爬虫的配置
第一部分关于爬虫的配置，包括编码、抓取间隔、超时时间、重试次数等，也包括一些模拟的参数，例如User Agent、cookie，以及代理的设置，我们会在第5章-“爬虫的配置”里进行介绍。在这里我们先简单设置一下：重试次数为3次，抓取间隔为一秒。
#### 3.1.2 页面元素的抽取
第二部分是爬虫的核心部分：对于下载到的Html页面，你如何从中抽取到你想要的信息？WebMagic里主要使用了三种抽取技术：XPath、正则表达式和CSS选择器。
1. XPath
XPath本来是用于XML中获取元素的一种查询语言，但是用于Html也是比较方便的。例如：
```java
page.getHtml().xpath("//h1[@class='entry-title public']/strong/a/text()")
```
这段代码使用了XPath，它的意思是“查找所有class属性为'entry-title public'的h1元素，并找到他的strong子节点的a子节点，并提取a节点的文本信息”。
对应的Html是这样子的：
![xpath-html](http://static.oschina.net/uploads/space/2014/0404/104607_Aqq8_190591.png)
2. CSS选择器
CSS选择器是与XPath类似的语言。如果大家做过前端开发，肯定知道$('h1.entry-title')这种写法的含义。客观的说，它比XPath写起来要简单一些，但是如果写复杂一点的抽取规则，就相对要麻烦一点。
3. 正则表达式
正则表达式则是一种通用的文本抽取语言。
```java
page.addTargetRequests(page.getHtml().links().regex("(https://github\\.com/\\w+/\\w+)").all());
```
这段代码就用到了正则表达式，它表示匹配所有"https://github.com/code4craft/webmagic"这样的链接。
XPath、CSS选择器和正则表达式的具体用法会在第4章“抽取工具详解”中讲到。
#### 3.1.3 链接的发现
有了处理页面的逻辑，我们的爬虫就接近完工了！
但是现在还有一个问题：一个站点的页面是很多的，一开始我们不可能全部列举出来，于是如何发现后续的链接，是一个爬虫不可缺少的一部分。
```java
page.addTargetRequests(page.getHtml().links().regex("(https://github\\.com/\\w+/\\w+)").all());
```
这段代码的分为两部分，`page.getHtml().links().regex("(https://github\\.com/\\w+/\\w+)").all()`用于获取所有满足"(https://github\\.com/\\w+/\\w+)"这个正则表达式的链接，`page.addTargetRequests()`则将这些链接加入到待抓取的队列中去。
### 3.2 使用Selectable的链式API
`Selectable`相关的链式API是WebMagic的一个核心功能。使用Selectable接口，你可以直接完成页面元素的链式抽取，也无需去关心抽取的细节。
在刚才的例子中可以看到，page.getHtml()返回的是一个`Html`对象，它实现了`Selectable`接口。这个接口包含一些重要的方法，我将它分为两类：抽取部分和获取结果部分。
#### 3.2.1 抽取部分API：
| 方法 | 说明 | 示例 |
| ------------ | ------------- | ------------ |
| xpath(String xpath) | 使用XPath选择 | html.xpath("//div[@class='title']") |
| \$(String selector) | 使用Css选择器选择 | html.\$("div.title") |
| \$(String selector,String attr) | 使用Css选择器选择 | html.\$("div.title","text") |
| css(String selector) | 功能同$()，使用Css选择器选择 | html.css("div.title") |
| links() | 选择所有链接 | html.links() |
| regex(String regex) | 使用正则表达式抽取 | html.regex("\<div\>(.\*?)\</div>") |
| regex(String regex,int group) | 使用正则表达式抽取，并指定捕获组 | html.regex("\<div\>(.\*?)\</div>",1) |
| replace(String regex, String replacement) | 替换内容| html.replace("\<script>.\*\</script>","")|
这部分抽取API返回的都是一个`Selectable`接口，意思是说，抽取是支持链式调用的。下面我用一个实例来讲解链式API的使用。
例如，我现在要抓取github上所有的Java项目，这些项目可以在[https://github.com/search?l=Java&p=1&q=stars%3A%3E1&s=stars&type=Repositories](https://github.com/search?l=Java&p=1&q=stars%3A%3E1&s=stars&type=Repositories)搜索结果中看到。
为了避免抓取范围太宽，我指定只从分页部分抓取链接。这个抓取规则是比较复杂的，我会要怎么写呢？
![selectable-chain-ui](http://static.oschina.net/uploads/space/2014/0404/151454_2T01_190591.png)
首先看到页面的html结构是这个样子的：
![selectable-chain](http://static.oschina.net/uploads/space/2014/0404/151632_88Oq_190591.png)
那么我可以先用CSS选择器提取出这个div，然后在取到所有的链接。为了保险起见，我再使用正则表达式限定一下提取出的URL的格式，那么最终的写法是这样子的：
```java
List<String> urls = page.getHtml().css("div.pagination").links().regex(".*/search/\?l=java.*").all();
```
然后，我们可以把这些URL加到抓取列表中去：
```java
List<String> urls = page.getHtml().css("div.pagination").links().regex(".*/search/\?l=java.*").all();
page.addTargetRequests(urls);
```
是不是比较简单？除了发现链接，Selectable的链式抽取还可以完成很多工作。我们会在第9章示例中再讲到。
#### 3.2.2 获取结果的API：
当链式调用结束时，我们一般都想要拿到一个字符串类型的结果。这时候就需要用到获取结果的API了。我们知道，一条抽取规则，无论是XPath、CSS选择器或者正则表达式，总有可能抽取到多条元素。WebMagic对这些进行了统一，你可以通过不同的API获取到一个或者多个元素。
| 方法 | 说明 | 示例 |
| ------------ | ------------- | ------------ |
| get() | 返回一条String类型的结果 | String link= html.links().get()|
| toString() | 功能同get()，返回一条String类型的结果 | String link= html.links().toString()|
| all() | 返回所有抽取结果 | List<String> links= html.links().all()|
| match() | 是否有匹配结果 | if (html.links().match()){ xxx; }|
例如，我们知道页面只会有一条结果，那么可以使用selectable.get()或者selectable.toString()拿到这条结果。
这里selectable.toString()采用了toString()这个接口，是为了在输出以及和一些框架结合的时候，更加方便。因为一般情况下，我们都只需要选择一个元素！
selectable.all()则会获取到所有元素。
好了，到现在为止，在回过头看看3.1中的GithubRepoPageProcessor，可能就觉得更加清晰了吧？指定main方法，已经可以看到抓取结果在控制台输出了。
### 3.3 保存结果
好了，爬虫编写完成，现在我们可能还有一个问题：我如果想把抓取的结果保存下来，要怎么做呢？WebMagic用于保存结果的组件叫做`Pipeline`。例如我们通过“控制台输出结果”这件事也是通过一个内置的Pipeline完成的，它叫做`ConsolePipeline`。那么，我现在想要把结果用Json的格式保存下来，怎么做呢？我只需要将Pipeline的实现换成"JsonFilePipeline"就可以了。
```java
public static void main(String[] args) {
Spider.create(new GithubRepoPageProcessor())
//从"https://github.com/code4craft"开始抓
.addUrl("https://github.com/code4craft")
.addPipeline(new JsonFilePipeline("D:\webmagic\"))
//开启5个线程抓取
.thread(5)
//启动爬虫
.run();
}
```
这样子下载下来的文件就会保存在D盘的webmagic目录中了。
通过定制Pipeline，我们还可以实现保存结果到文件、数据库等一系列功能。这个会在第7章“抽取结果的处理”中介绍。
至此为止，我们已经完成了一个基本爬虫的编写，也具有了一些定制功能。
