--------------------

## 一、简单介绍 ##

Unity Android 开发上会用到的技术简单整理，方便自己日后查看，能帮助到大家就更好了。

本节介绍，Unity 开发中，把从 Android 使用 jsoup 爬虫爬取到的新闻信息（爬取的是凤凰网的新闻：https://news.ifeng.com/）的接口的方法整理封装给Unity调用，方法不唯一，欢迎指正。

其中，纯 Android 的 jsoup 爬取使用，可参见下面的博文：

[Android Studio 爬虫 之 简单实现使用 jsoup/okhttp3 爬取购物商品信息的案例demo（附有详细步骤）][Android Studio _ _ _ jsoup_okhttp3 _demo]

## 二、实现原理 ##

1、okhttp3 获得网页的 html 内容

2、jsoup  解析 html 的内容，获取需要的部分信息

3、打包 aar ，给 Unity 进行调用

## 三、注意事项 ##

1、网页的 html 有些格式标签可能会变化，具体根据实际最新的网页 html 为准

2、AndroidManifest.xml 中注意添加 INTERNET 权限

3、okhttp3 依赖 okio (最好下载 okio-1.16.0.jar)，使用的时候也要添加这个 jar 包

## 四、效果预览 ##

## 五、网页数据分析，以确认 jsoup 解析需要的数据 ##

1、爬取目标网页

（网址为：[https://news.ifeng.com/][https_news.ifeng.com]）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 1][]

2、选中网页右键 检查元素（这里以火狐浏览器为例），查看 html 源码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 2][]

3、点击选中 鼠标选择器，这样选择 html 就会和 网页 双双对应

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 3][]

4、Elements 的目标 html 为如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 4][]

5、title 的目标 html 为如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 5][]

6、source 的目标 html 为如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 6][]

7、imgurl 的目标 html 为如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 7][]

8、commentNum 的目标 html 为如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 8][]

9、articleurl 的目标 html 为如下

(获取的方法很多，我根据图片获取的)

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 9][]

## 六、实现步骤 ##

### Android 端 ###

1、打开 Android Studio 之后，新建一个工程或者一个模块

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 10][]

2、选择 模块，点击 Next

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 11][]

3、把jsoup、okhttp、okio都引入模块中

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 12][]

4、编写相关代码，NewsStruct 为数据模型类，OkHttpUtils 获取网页 html，GetNewsStructDataUtil 解析 html 整理成列表NewsStruct 模型数据，GetNewsDataJsonStringListener 线程 爬取完新闻数据的毁掉监听接口

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 13][]

5、脚本编辑 OK，Build - Make Module ‘xxxx’，打包 aar

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 14][]

6、打包成功，build 文件夹outputs/aar中就会 有对应的 aar 生成

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 15][]

### Unity 端 ###

1、把 Android 打包的 aar 导入 Unity，这里用到 LitJson 也一并导入

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 16][]

2、在场景中布局UI，Grid 获取 Layout 排布获取的新闻数据，并把 NewsDataItem 作为预制体，其中 Grid  的 Layout  如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 17][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 18][]

3、在 Unity工程中，新建脚本，编辑对应功能，JsoupCrawlerNewsDataWrapper 接口Android aar 获取 新闻数据，GetNewsDataJsonStringListener 获取新闻数据完成的监听接口类，NewsDataStruct 新闻类数据结构，NewsDataItem 新闻预制体类，MonoSingleton 单例类，TestJsoupCrawlerNewsDataWrapper 测试 JsoupCrawlerNewsDataWrapper  的功能

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 19][]

4、把 TestJsoupCrawlerNewsDataWrapper 挂载到场景中，并对应赋值

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 20][]

5、运行场景，没有问题，即可打包到真机上测试

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 21][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70 22][]

6、真机上的测试效果如上

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQzNjEyODA_size_16_color_FFFFFF_t_70][]

            }
            return arr.toString();
        }
    }

2、NewsStruct

package com.example.javacrawlerwrapper;
    
    public class NewsStruct {
    
        private String title;
        private String classify;
        private String source;
        private String imgUrl;
        private String commentNum;
        private String articleUrl;
    
        public NewsStruct(String title, String classify, String source, String imgUrl, String commentNum, String articleUrl) {
            this.title = title;
            this.classify = classify;
            this.source = source;
            this.imgUrl = imgUrl;
            this.commentNum = commentNum;
            this.articleUrl = articleUrl;
        }
    
        public String getTitle() {
            return title;
        }
    
        public void setTitle(String title) {
            this.title = title;
        }
    
        public String getClassify() {
            return classify;
        }
    
        public void setClassify(String classify) {
            this.classify = classify;
        }
    
        public String getSource() {
            return source;
        }
    
        public void setSource(String source) {
            this.source = source;
        }
    
        public String getImgUrl() {
            return imgUrl;
        }
    
        public void setImgUrl(String imgUrl) {
            this.imgUrl = imgUrl;
        }
    
        public String getCommentNum() {
            return commentNum;
        }
    
        public void setCommentNum(String commentNum) {
            this.commentNum = commentNum;
        }
    
        public String getArticleUrl() {
            return articleUrl;
        }
    
        public void setArticleUrl(String articleUrl) {
            this.articleUrl = articleUrl;
        }
    
        @Override
        public String toString() {
            return "NewsStruct{" +
                    "title='" + title + '\'' +
                    ", classify='" + classify + '\'' +
                    ", source='" + source + '\'' +
                    ", imgUrl='" + imgUrl + '\'' +
                    ", commentNum='" + commentNum + '\'' +
                    ", articleUrl='" + articleUrl + '\'' +
                    '}';
        }
    }

3、OkHttpUtils

package com.example.javacrawlerwrapper;
    
    import java.io.IOException;
    
    import okhttp3.OkHttpClient;
    import okhttp3.Request;
    import okhttp3.Response;
    
    
    public class OkHttpUtils {
    
        final static String TAG = "OkHttpUtils";
    
        public static String OkGetArt(String url) {
            String html = null;
            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder()
                    .url(url)
                    .build();
            try  {
            Response response = client.newCall(request).execute();
            //return
                html = response.body().string();
            } catch (IOException e) {
                e.printStackTrace();
            }
            //Log.i(TAG, "OkGetArt: html "+html);
            return html;
    
        }
    }
