基于hive分析Flask为后端框架echarts为前端框架的招聘网站可视化大屏项目
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。
ECharts：JavaScript 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', mode='a', encoding='utf-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',encoding='utf-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-job"headers = {'Accept': 'application/json, text/plain, */*','Accept-Encoding': 'gzip, deflate, br','Accept-Language': 'zh-CN,zh;q=0.9','Connection': 'keep-alive','Sec-Ch-Ua-Platform':'macOS','Content-Length': '398','Content-Type': 'application/json;charset=UTF-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";v="119", "Chromium";v="119", "Not?A_Brand";v="24"','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(url=url, json=data, headers=headers)time.sleep(2)parse_data(response)def parse_data(response):try:jobCardList = response.json()['data']['data']['jobCardList']except Exception as e:return
4、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 '\n'sqoop 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 '\n'sqoop 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 '\n'
6. 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__)
app.secret_key = 'b6b52fae-5618-4805-b368-501c62c6d1df'@app.after_request
def add_header(response):response.cache_control.max_age = 0return response@app.route('/', methods=['GET', 'POST'])
def login():if request.method == 'POST':username = request.form['username']password = request.form['password']user = get_user(username, password)# 检查用户是否存在if user is not None:data = SourceData()return render_template('index.html', form=data, title=data.title)else:# 用户名或密码错误，显示错误消息flash('用户名或密码错误')return redirect(url_for('login')) # 重定向回登录页面# 如果是 GET 请求，则直接返回登录页面return render_template('login.html')@app.route('/register', methods=['GET', 'POST'])
def register():if request.method == 'POST':username = request.form.get('username')password = request.form.get('password')if username and password:register_user(username, password) # 确保此函数已定义return "注册成功！"flash('用户名和密码不能为空')return redirect(url_for('register'))return render_template('register.html')if __name__ == "__main__":app.run(host='127.0.0.1', debug=False)

8、总结
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。
