1. 项目概述
项目目标是构建一个大数据分析系统包含以下核心模块 1、数据爬取通过request请求获取猎聘网的就业数据。 2、数据存储和分析使用 Hive 进行数据存储和分析。 3、数据迁移使用sqoop将hive数据导入mysql。 4、后端服务使用 Flask 搭建数据接口将分析结果提供给前端。 5、数据可视化使用 ECharts 制作大屏展示实现数据的图形化呈现。
2. 项目环境准备
在开始之前需要搭建如下环境
Hive作为数据仓库用于存储和分析数据。 Flask轻量级 Python Web 框架用于构建后端 RESTful API。 EChartsJavaScript 图表库用于前端数据可视化。 MySQL用于保存一些系统配置或小规模数据。 Sqoop数据同步工具将hive数据同步到mysql。
3、数据爬取
通过python获取猎聘网的照片信息存储到csv文件里
import csv
import timeimport requests
import execjsfrom storage.csv2mysql import sync_data2dbf open(../storage/data.csv, modea, encodingutf-8)
csv_writer csv.DictWriter(f,fieldnames[职位,城市,薪资,经验,标签,公司,公司领域,公司规模])
csv_writer.writeheader()def read_js_code():f open(/Users/shareit/workspace/chart_show/demo.js,encodingutf-8)txt f.read()js_code execjs.compile(txt)ckId js_code.call(r,32)return ckIddef post_data():read_js_code()url https://api-c.liepin.com/api/com.liepin.searchfront4c.pc-search-jobheaders {Accept: application/json, text/plain, */*,Accept-Encoding: gzip, deflate, br,Accept-Language: zh-CN,zh;q0.9,Connection: keep-alive,Sec-Ch-Ua-Platform:macOS,Content-Length: 398,Content-Type: application/json;charsetUTF-8;,Host: api-c.liepin.com,User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36,Origin: https://www.liepin.com,Referer: https://www.liepin.com/,Sec-Ch-Ua: Google Chrome;v119, Chromium;v119, Not?A_Brand;v24,Sec-Ch-Ua-Mobile: ?0,Sec-Fetch-Dest: empty,Sec-Fetch-Mode: cors,Sec-Fetch-Site: same-site,X-Client-Type: web,X-Fscp-Bi-Stat: {location: https://www.liepin.com/zhaopin},X-Fscp-Fe-Version: ,X-Fscp-Std-Info: {client_id: 40108},X-Fscp-Trace-Id: 52262313-e6ca-4cfd-bb67-41b4a32b8bb5,X-Fscp-Version: 1.1,X-Requested-With: XMLHttpRequest,}list [H01$H0001,H01$H0002,H01$H0003,H01$H0004,H01$H0005,H01$H0006,H01$H0007,H01$H0008,H01$H0009,H01$H00010,H02$H0018,H02$H0019,H03$H0022,H03$H0023,H03$H0024,H03$H0025,H04$H0030,H04$H0031,H04$H0032,H05$H05,H06$H06,H07$H07,H08$H08]for name in list:print(-------{}---------.format(name))for i in range(10):print(------------第{}页-----------.format(i))data {data: {mainSearchPcConditionForm:{city: 410, dq: 410, pubTime: , currentPage: i, pageSize: 40, key: ,suggestTag: , workYearCode: 1, compId: , compName: , compTag: ,industry: name, salary: , jobKind: , compScale: , compKind: , compStage: ,eduLevel: },passThroughForm:{scene: page, skId: z33lm3jhwza7k1xjvcyn8lb8e9ghxx1b,fkId: z33lm3jhwza7k1xjvcyn8lb8e9ghxx1b,ckId: read_js_code(),sfrom: search_job_pc}}}response requests.post(urlurl, jsondata, headersheaders)time.sleep(2)parse_data(response)def parse_data(response):try:jobCardList response.json()[data][data][jobCardList]except Exception as e:return4、加载hive数据进行分析
1、将storage下的data.csv上传到虚拟机上 2、创建work_base表并将data.csv数据加载到hive表里
CREATE TABLE work_base (id INT COMMENT id,title STRING COMMENT 标题,city STRING COMMENT 城市,salary STRING COMMENT 薪资,campus_job_kind STRING COMMENT 经验,labels STRING COMMENT 标签,compName STRING COMMENT 公司,compIndustry STRING COMMENT 公司领域,compScale STRING COMMENT 公司规模
) ROW FORMAT DELIMITED FIELDS TERMINATED BY , STORED AS TEXTFILE;LOAD local DATA INPATH ./data.csv OVERWRITE INTO TABLE flask_work.work_base;3、创建hive ads层数仓表进行分析 -- 4. 热门公司分析
CREATE TABLE top_companies (company_name STRING COMMENT 公司名称,job_count INT COMMENT 职位数量
) STORED AS TEXTFILE;INSERT INTO top_companies
SELECT compName, COUNT(*) AS job_count
FROM work_base
GROUP BY compName
ORDER BY job_count DESC
LIMIT 10;-- 5. 岗位分布情况分析
CREATE TABLE job_distribution (job_title STRING COMMENT 岗位名称,job_count INT COMMENT 职位数量
) STORED AS TEXTFILE;INSERT INTO job_distribution
SELECT title, COUNT(*) AS job_count
FROM work_base
GROUP BY title;-- 6. 学历要求分析
CREATE TABLE education_requirements (education_level STRING COMMENT 学历要求,job_count INT COMMENT 职位数量
) STORED AS TEXTFILE;INSERT INTO education_requirements
SELECTCASEWHEN labels LIKE %博士% THEN 博士WHEN labels LIKE %硕士% THEN 硕士WHEN labels LIKE %本科% THEN 本科WHEN labels LIKE %大专% THEN 大专ELSE 其他END AS education_level,COUNT(*) AS job_count
FROM work_base
GROUP BY education_level;-- 7. 薪资待遇分析各个城市的平均薪资
CREATE TABLE city_salary_analysis (city STRING COMMENT 城市,avg_salary DOUBLE COMMENT 平均薪资
) STORED AS TEXTFILE;INSERT INTO city_salary_analysis
SELECT city, AVG(CAST(salary AS DOUBLE)) AS avg_salary
FROM work_base
WHERE salary RLIKE ^[0-9]$
GROUP BY city;
5、将hive分析的结果数据导入mysql
使用sqoop迁移数据
sqoop export \--connect jdbc:mysql://localhost:3306/flask_work \--username root --password 123456 \--table city_job_count \--export-dir /hive/warehouse/flask_work.db/flask_work.city_job_count \--input-fields-terminated-by \001 \--input-lines-terminated-by \n;sqoop export \--connect jdbc:mysql:// localhost:3306/flask_work \--username root --password 123456 \--table job_salary_analysis \--export-dir /user/hive/warehouse/flask_work.db/flask_work.job_salary_analysis \--input-fields-terminated-by \001 \--input-lines-terminated-by \nsqoop export \--connect jdbc:mysql:// localhost:3306/flask_work \--username root --password 123456 \--table top_companies \--export-dir /user/hive/warehouse/flask_work.db/flask_work.top_companies \--input-fields-terminated-by \001 \--input-lines-terminated-by \nsqoop export \--connect jdbc:mysql:// localhost:3306/flask_work \--username root --password 123456 \--table job_distribution \--export-dir /user/hive/warehouse/flask_work.db/flask_work.job_distribution \--input-fields-terminated-by \001 \--input-lines-terminated-by \n6. 后端服务Flask
使用 Flask 构建后端服务编写rest api读取mysql数据提供给前端页面进行展示 app.py
from flask import Flask, render_template, request, flash, redirect, url_for
from data import *
from service.task_service import get_user, register_userapp Flask(__name__)

通过 request爬虫获取数据使用Hive 进行大数据分析、通过sqoop进行数据迁移最后使用Flask 构建后端接口获取mysql数据提供给前端再结合 ECharts 前端可视化能够构建一个完整的大数据展示系统。
