《花100块做个摸鱼小网站! 》第二篇—后端应用搭建和完成第一个爬虫
来源:cnblogs  作者:sum墨  时间:2024/8/19 15:51:53  对本文有异议

一、前言

大家好呀,我是summo,前面已经教会大家怎么去阿里云买服务器(链接在这,需要自取),以及怎么搭建JDK、Redis、MySQL这些环境或者数据库。从这篇文章开始就进入正式的编码阶段了,我们从后端开始,先把热搜数据获取到,然后再开始前端部分。

本来我想把后端应用搭建和完成第一个爬虫分为两篇文章写的,但是想到墨迹三周还没看到效果,估计有些同学已经等不及了,所以我把这两篇文章合成一篇了,篇幅比较长,感兴趣的同学可以认真看下。因为后端应用初始化的时候涉及很多配置,有很多命名,建议大家写别急着个性化用自己的名字命名应用和配置,可以先用我的命名方式搭建一个出来,先成功再研究个性化,这样成就感很足,学习动力也强。

二、后端应用搭建

这个摸鱼小网站主要使用的SpringBoot框架配合一些中间件实现,开发工具用的是idea社区版,建议不要下载人家的正式版然后破解,一来麻烦的很,二来社区版足够开发使用了,点击这个可以下载idea社区版

1. maven项目搭建

打开idea后,点击New Project,我们从一个空的maven项目开始,一步步把项目搭建出来。

我们输入name、GroupId、ArtifactId点击确定,如果你是老手可以自己搭建,如果你是新手建议跟我输的一样,因为后面还有很多地方要用的这些名字

把src目录删掉,我们不需要,只留下pom.xml文件就行了。

接下来我们开始创建子module,创建方式如下图:

以summo-sbmy-start子module为例,输入如下的信息就可以创建一个module出来啦。

按照这个方式创建出如下的module出来。

2. pom.xml配置

这部分我现在不详细说,后面我会单独写一篇文章讲我的依赖和配置。如果刚才你的名字取得跟我一样,直接复制粘贴就完事了,如果名字不一样记得把名字给替换为你的。

(1)summo-sbmy

            <fileNamePattern>${LOG_PATH}/error.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <!-- 文件保留最大天数 -->
            <maxHistory>7</maxHistory>
            <!-- 文件大小限制 -->
            <maxFileSize>50MB</maxFileSize>
            <!-- 文件总大小 -->
            <totalSizeCap>500MB</totalSizeCap>
        </rollingPolicy>
        <!-- 日志过滤器,将ERROR相关日志过滤出来 -->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
    </appender>

    <!-- 配置控制台输出 -->
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>

    </appender>


    <!-- 配置输出级别 -->
    <root level="INFO">
        <!-- 加入控制台输出 -->
        <appender-ref ref="CONSOLE"/>
        <!-- 加入APPLICATION输出 -->
        <appender-ref ref="APPLICATION"/>
        <!-- 加入WARN日志输出 -->
        <appender-ref ref="WARN"/>
        <!-- 加入ERROR日志输出 -->
        <appender-ref ref="ERROR"/>
    </root>
</configuration>

5. 创建启动类

package com.summo.sbmy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

/**
 * @author summo
 * @version Application.java, 1.0.0
 * @description 启动核心类
 * @date 2024年08月09
 */
@SpringBootApplication(scanBasePackages = {"com.summo.sbmy"})
@EnableScheduling
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

点击启动,打印如下就算成功

三、实现抖音热搜爬虫

第一次写爬虫代码,我们找一个最简单,也是最安全的例子,抖音热搜

1. 爬虫方案评估

为什么简单?
它就一个接口:https://www.iesdouyin.com/web/api/v2/hotsearch/billboard/word/,免登录也不需要参数,你们直接在浏览器上调用就可以把抖音的热搜数据获取到了;

为什么安全?
调用https://www.iesdouyin.com/robots.txt接口,返回如下:

User-agent: *
Allow: /

Sitemap: http://www.iesdouyin.com/sitemap/index.xml

这个代表什么呢?

看到了吗,人家不仅允许你去爬,还提供了网站地图的链接,这也是他们为了提高谷歌、必应、百度等浏览器的收录的一种办法。所以,不用担心爬这些数据会怎么样了。

2. 获取链接的cURL代码

先上一张图,如下:

大概的步骤如下:

  1. 输入https://www.iesdouyin.com/web/api/v2/hotsearch/billboard/word/链接,按下enter;
  2. 打开控制台,选择【全部】找到刚才调用的接口;
  3. 选中接口,右键打开菜单,选择复制里面的“以cURL格式复制”这一项。

复制出来是这样的东西

curl 'https://www.iesdouyin.com/web/api/v2/hotsearch/billboard/word/'   -H 'accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7'   -H 'accept-language: zh-CN,zh;q=0.9'   -H 'cache-control: no-cache'   -H 'cookie: ttwid=1%7CJ6ehEognyMAob_gD6oZwA40monN8E_sENr3IUZmuk7o%7C1712472728%7C44b0cd0003fb75861789d62e56f014eaea3d198898a0ae9a947bf61d95d8ac1a; __ac_signature=_02B4Z6wo00f01fFoqvgAAIDBFmj97SX8qiXxSK5AABr708; __ac_referer=https://pre-dc-console.alibaba-inc.com/'   -H 'pragma: no-cache'   -H 'priority: u=0, i'   -H 'sec-ch-ua: "Not/A)Brand";v="8", "Chromium";v="126", "Google Chrome";v="126"'   -H 'sec-ch-ua-mobile: ?0'   -H 'sec-ch-ua-platform: "macOS"'   -H 'sec-fetch-dest: document'   -H 'sec-fetch-mode: navigate'   -H 'sec-fetch-site: none'   -H 'sec-fetch-user: ?1'   -H 'upgrade-insecure-requests: 1'   -H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36'

能看懂吗?能看懂最好,看不懂也没有关系,不是给我们看的,给Postman看的。Postman是一个http接口调用工具非常好用,电脑上没有Postman的同学就去下载一个。

3. 使用Postman生成调用代码

打开你的Postman软件,按照我下面这张图操作:

按照我上面的步骤,将cURL命令导入Postman,可以快速生成一个调用请求,如下图:

这个方式也可以用在我们平时调试接口,比如说有一个接口报错了,需要不断地叫前端重试一下,再重试一下,非常麻烦。这个时候你就可以叫前端把这个cURL复制给你,自己动手重试,就不用麻烦别人啦。

在Postman的右上角有一个Code snippet,可以直接生成你想要的调用代码,啥Java、Python、NodeJs都有,不用自己写,复制就可以运行。咋样,Postman没有白骗你下载吧!

代码如下

OkHttpClient client = new OkHttpClient().newBuilder()
  .build();
Request request = new Request.Builder()
  .url("https://www.iesdouyin.com/web/api/v2/hotsearch/billboard/word/")
  .method("GET", null)
  .addHeader("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7")
  .addHeader("accept-language", "zh-CN,zh;q=0.9")
  .addHeader("cache-control", "no-cache")
  .addHeader("cookie", "ttwid=1%7CJ6ehEognyMAob_gD6oZwA40monN8E_sENr3IUZmuk7o%7C1712472728%7C44b0cd0003fb75861789d62e56f014eaea3d198898a0ae9a947bf61d95d8ac1a; __ac_signature=_02B4Z6wo00f01fFoqvgAAIDBFmj97SX8qiXxSK5AABr708; __ac_referer=https://pre-dc-console.alibaba-inc.com/; ttwid=1%7CX9ppA_NoTHJI9DG3JN7wNnZ662r-aJbZwCFPLLGK-og%7C1713836331%7Cdbc79a439d0ecc994f60043d66b4ad3ff81c3820f3ab83ef85d30875cc59a18b")
  .addHeader("pragma", "no-cache")
  .addHeader("priority", "u=0, i")
  .addHeader("sec-ch-ua", "\"Not/A)Brand\";v=\"8\", \"Chromium\";v=\"126\", \"Google Chrome\";v=\"126\"")
  .addHeader("sec-ch-ua-mobile", "?0")
  .addHeader("sec-ch-ua-platform", "\"macOS\"")
  .addHeader("sec-fetch-dest", "document")
  .addHeader("sec-fetch-mode", "navigate")
  .addHeader("sec-fetch-site", "none")
  .addHeader("sec-fetch-user", "?1")
  .addHeader("upgrade-insecure-requests", "1")
  .addHeader("user-agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36")
  .build();
Response response = client.newCall(request).execute();

4. 将代码迁移到应用中

summo-sbmy-job这个module下,创建一个文件夹com.summo.sbmy.job.douyin,创建DouyinHotSearchJob.java,代码如下

package com.summo.sbmy.job.douyin;

import java.io.IOException;

import com.alibaba.fastjson.JSONObject;

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

/**
 * @author summo
 * @version DouyinHotSearchJob.java, 1.0.0
 * @description 抖音热搜Java爬虫代码
 * @date 2024年08月09
 */
@Component
public class DouyinHotSearchJob {

    /**
     * 定时触发爬虫方法,1个小时执行一次
     */
    @Scheduled(fixedRate = 1000 * 60 * 60)
    public void hotSearch() throws IOException {
        OkHttpClient client = new OkHttpClient().newBuilder()
            .build();
        Request request = new Request.Builder()
            .url("https://www.iesdouyin.com/web/api/v2/hotsearch/billboard/word/")
            .method("GET", null)
            .addHeader("accept",
                       "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;"
                           + "q=0.8,application/signed-exchange;v=b3;q=0.7")
            .addHeader("accept-language", "zh-CN,zh;q=0.9")
            .addHeader("cache-control", "no-cache")
            .addHeader("cookie",
                       "ttwid=1%7CJ6ehEognyMAob_gD6oZwA40monN8E_sENr3IUZmuk7o%7C1712472728"
                           + "%7C44b0cd0003fb75861789d62e56f014eaea3d198898a0ae9a947bf61d95d8ac1a; "
                           + "__ac_signature=_02B4Z6wo00f01fFoqvgAAIDBFmj97SX8qiXxSK5AABr708; "
                           + "__ac_referer=https://pre-dc-console.alibaba-inc.com/; "
                           + "ttwid=1%7CX9ppA_NoTHJI9DG3JN7wNnZ662r-aJbZwCFPLLGK-og%7C1713836331"
                           + "%7Cdbc79a439d0ecc994f60043d66b4ad3ff81c3820f3ab83ef85d30875cc59a18b")
            .addHeader("pragma", "no-cache")
            .addHeader("priority", "u=0, i")
            .addHeader("sec-ch-ua", "\"Not/A)Brand\";v=\"8\", \"Chromium\";v=\"126\", \"Google Chrome\";v=\"126\"")
            .addHeader("sec-ch-ua-mobile", "?0")
            .addHeader("sec-ch-ua-platform", "\"macOS\"")
            .addHeader("sec-fetch-dest", "document")
            .addHeader("sec-fetch-mode", "navigate")
            .addHeader("sec-fetch-site", "none")
            .addHeader("sec-fetch-user", "?1")
            .addHeader("upgrade-insecure-requests", "1")
            .addHeader("user-agent",
                       "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) "
                           + "Chrome/126.0.0.0 Safari/537.36")
            .build();
        Response response = client.newCall(request).execute();
        System.out.println(JSONObject.toJSONString(response.body().string()));
    }

}

这个爬虫代码会在启动的时候执行一次,然后每一小时执行一次。这样,我们的第一个定时爬虫就做好了。如果以上的内容你都看不懂,那就直接复制我这代码吧,鱼和渔都给你了。

四、小结一下

这一篇配置文件很多,篇幅很长,大家要耐心和细心一些,不然很容易出错。这里给出的配置是按照最终版给的,到时开发的时候不用担心少依赖或者少包,至于原理和选型后面再单独说吧。我觉得看一个Java程序员经验丰不丰富从他搭建的脚手架就可以看出来,因为脚手架不像代码一样有标准,它是由框架和插件构成的,适合你就用,没有什么是必须的。

还有就是爬虫,可能有些同学会失望,这玩意咋这么简单,一点技术含量都没有。简单的原因一是热搜接口都是免登无校验的,二是因为我已经给你们趟了一条路出来,饭喂到嘴里了。后面还有很多热搜爬虫,有些也挺麻烦的,不用急,我会慢慢公布。
大多数同学大多数时间都只是在干CRUD的活,也没有独立建站的经验,虽然没有但是可以学!现在不会练练就会!100块钱的实操经验绝对比100块钱买的专栏更有意义更有用!

最后,自建摸鱼网站,各大网站热搜一览,上班和摸鱼很配哦!
