目前，大厂的服务范围越来越广，提供的数据信息也是比较全的，在生活服务，办公领域，人工智能等方面都全面覆盖，相对来说，他们的用户基数大，通过用户获取的信息也是巨大的。除了百度提供api，国内提供免费API获取数据的还有很多，包括新浪、豆瓣电影、饿了么、阿里、腾讯等今天使用百度地图API来请求我们想要的数据。
第一步.注册百度开发者账号
注册成功后就可以获取到应用服务AK也就是API秘钥，这个是最重要的，应用名称可以随便取，如果是普通用户一天只有2000调用限额，认证用户一天有10万次调用限额
在百度地图web服务API文档中我可以看见提供的接口和相关参数，其中就有我们要获取的AK参数，使用的GET请求
一.下面我们尝试使用API获取获取北京市的城市公园数据，需要配置参数
import requests import json def getjson(loc): headers = {‘User-Agent‘ : ‘Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6‘} pa = { ‘q‘: ‘公园‘, ‘region‘: loc, ‘scope‘: ‘2‘, ‘page_size‘: 20, ‘page_num‘: 0, ‘output‘: ‘json‘, ‘ak‘: ‘填写自己的AK‘ } r = requests.get("http://api.map.baidu.com/place/v2/search", params=pa, headers= headers) decodejson = json.loads(r.text) return decodejson getjson(‘北京市‘)
二.获取所有拥有公园的城市
import requests import json def getjson(loc): headers = {‘User-Agent‘ : ‘Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6‘} pa = { ‘q‘: ‘公园‘, ‘region‘: loc, ‘scope‘: ‘2‘, ‘page_size‘: 20, ‘page_num‘: 0, ‘output‘: ‘json‘, ‘ak‘: ‘填写自己的AK‘ } r = requests.get("http://api.map.baidu.com/place/v2/search", params=pa, headers= headers) decodejson = json.loads(r.text) return decodejson province_list = [‘江苏省‘, ‘浙江省‘, ‘广东省‘, ‘福建省‘, ‘山东省‘, ‘河南省‘, ‘河北省‘, ‘四川省‘, ‘辽宁省‘, ‘云南省‘, ‘湖南省‘, ‘湖北省‘, ‘江西省‘, ‘安徽省‘, ‘山西省‘, ‘广西壮族自治区‘, ‘陕西省‘, ‘黑龙江省‘, ‘内蒙古自治区‘, ‘贵州省‘, ‘吉林省‘, ‘甘肃省‘, ‘新疆维吾尔自治区‘, ‘海南省‘, ‘宁夏回族自治区‘, ‘青海省‘, ‘西藏自治区‘] for eachprovince in province_list: decodejson = getjson(eachprovince) #print(decodejson["results"]) for eachcity in decodejson.get(‘results‘): print(eachcity) city = eachcity[‘name‘] #print(city) num = eachcity[‘num‘] output = ‘\t‘.join([city, str(num)]) + ‘\r\n‘ with open(‘cities.txt‘, "a+", encoding=‘utf-8‘) as f: f.write(output) f.close()
import requests import json def getjson(loc): headers = {‘User-Agent‘ : ‘Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6‘} pa = { ‘q‘: ‘公园‘, ‘region‘: loc, ‘scope‘: ‘2‘, ‘page_size‘: 20, ‘page_num‘: 0, ‘output‘: ‘json‘, ‘ak‘: ‘填写自己的AK‘ } r = requests.get("http://api.map.baidu.com/place/v2/search", params=pa, headers= headers) decodejson = json.loads(r.text) return decodejson decodejson = getjson(‘全国‘) six_cities_list = [‘北京市‘,‘上海市‘,‘重庆市‘,‘天津市‘,‘香港特别行政区‘,‘澳门特别行政区‘,] for eachprovince in decodejson[‘results‘]: city = eachprovince[‘name‘] num = eachprovince[‘num‘] if city in six_cities_list: output = ‘\t‘.join([city, str(num)]) + ‘\r\n‘ with open(‘cities789.txt‘, "a+", encoding=‘utf-8‘) as f: f.write(output) f.close()
保存到文件
三.获取所有城市的公园数据，在从各个城市获取数据之前，先在MySQL建立baidumap数据库，用来存放所有的数据
#coding=utf-8 import pymysql conn= pymysql.connect(host=‘localhost‘ , user=‘root‘, passwd=‘*******‘, db =‘baidumap‘, charset="utf8") cur = conn.cursor() sql = """CREATE TABLE city ( id INT NOT NULL AUTO_INCREMENT, city VARCHAR(200) NOT NULL, park VARCHAR(200) NOT NULL, location_lat FLOAT, location_lng FLOAT, address VARCHAR(200), street_id VARCHAR(200), uid VARCHAR(200), created_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (id) );""" cur.execute(sql) cur.close() conn.commit() conn.close()
city_list = list() with open("cities.txt", ‘r‘, encoding=‘utf-8‘) as txt_file: for eachLine in txt_file: if eachLine != "" and eachLine != "\n": fields = eachLine.split("\t") city = fields[0] city_list.append(city) txt_file.close()
#接下来爬取每个城市的数据，并将其加入city数据表中
import requests import json import pymysql conn= pymysql.connect(host=‘localhost‘ , user=‘root‘, passwd=‘********‘, db =‘baidumap‘, charset="utf8") cur = conn.cursor() def getjson(loc,page_num): headers = {‘User-Agent‘ : ‘Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6‘} pa = { ‘q‘: ‘公园‘, ‘region‘: loc, ‘scope‘: ‘2‘, ‘page_size‘: 20, ‘page_num‘: page_num, ‘output‘: ‘json‘, ‘ak‘: ‘填写自己的AK‘ } r = requests.get("http://api.map.baidu.com/place/v2/search", params=pa, headers= headers) decodejson = json.loads(r.text) return decodejson for eachcity in city_list: not_last_page = True page_num = 0 while not_last_page: decodejson = getjson(eachcity, page_num) #print (eachcity, page_num) if decodejson[‘results‘]: for eachone in decodejson[‘results‘]: try: park = eachone[‘name‘] except: park = None try: location_lat = eachone[‘location‘][‘lat‘] except: location_lat = None try: location_lng = eachone[‘location‘][‘lng‘] except: location_lng = None try: address = eachone[‘address‘] except: address = None try: street_id = eachone[‘street_id‘] except: street_id = None try: uid = eachone[‘uid‘] except: uid = None sql = """INSERT INTO baidumap.city (city, park, location_lat, location_lng, address, street_id, uid) VALUES (%s, %s, %s, %s, %s, %s, %s);""" cur.execute(sql, (eachcity, park, location_lat, location_lng, address, street_id, uid,)) conn.commit() page_num += 1 else: not_last_page = False cur.close() conn.close()
四.获取所有公园的详细信息
baidumap数据库已经有了city这个表格，存储了所有城市的公园数据，但是这个数据比较粗糙，接下来我们使用百度地图检索服务获取没一个公园的详情
#coding=utf-8 import pymysql conn= pymysql.connect(host=‘localhost‘ , user=‘root‘, passwd=‘*******‘, db =‘baidumap‘, charset="utf8") cur = conn.cursor() sql = """CREATE TABLE park ( id INT NOT NULL AUTO_INCREMENT, park VARCHAR(200) NOT NULL, location_lat FLOAT, location_lng FLOAT, address VARCHAR(200), street_id VARCHAR(200), telephone VARCHAR(200), detail INT, uid VARCHAR(200), tag VARCHAR(200), type VARCHAR(200), detail_url VARCHAR(800), price INT, overall_rating FLOAT, image_num INT, comment_num INT, shop_hours VARCHAR(800), alias VARCHAR(800), keyword VARCHAR(800), scope_type VARCHAR(200), scope_grade VARCHAR(200), description VARCHAR(9000), created_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (id) );""" cur.execute(sql) cur.close() conn.commit() conn.close()
import requests import json import pymysql conn= pymysql.connect(host=‘localhost‘ , user=‘root‘, passwd=‘********‘, db =‘baidumap‘, charset="utf8") cur = conn.cursor() sql = "Select uid from baidumap.city where id > 0;" cur.execute(sql) conn.commit() results = cur.fetchall() cur.close() conn.close()
import requests import json import pymysql conn= pymysql.connect(host=‘localhost‘ , user=‘root‘, passwd=‘********‘, db =‘baidumap‘, charset="utf8") cur = conn.cursor() sql = "Select uid from baidumap.city where id > 0;" cur.execute(sql) conn.commit() results = cur.fetchall() #print(results) def getjson(uid): headers = {‘User-Agent‘ : ‘Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6‘} pa = { ‘uid‘: uid, ‘scope‘: ‘2‘, ‘output‘: ‘json‘, ‘ak‘: ‘填写自己的AK‘ } r = requests.get("http://api.map.baidu.com/place/v2/search", params=pa, headers= headers) decodejson = json.loads(r.text) return decodejson for row in results: print(row) uid = row[0] decodejson = getjson(uid) #print (uid) info = decodejson[‘result‘] try: park = info[‘name‘] except: park = None try: location_lat = info[‘location‘][‘lat‘] except: location_lat = None try: location_lng = info[‘location‘][‘lng‘] except: location_lng = None try: address = info[‘address‘] except: address = None try: street_id = info[‘street_id‘] except: street_id = None try: telephone = info[‘telephone‘] except: telephone = None try: detail = info[‘detail‘] except: detail = None try: tag = info[‘detail_info‘][‘tag‘] except: tag = None try: detail_url = info[‘detail_info‘][‘detail_url‘] except: detail_url = None try: type = info[‘detail_info‘][‘type‘] except: type = None try: overall_rating = info[‘detail_info‘][‘overall_rating‘] except: overall_rating = None try: image_num = info[‘detail_info‘][‘image_num‘] except: image_num = None try: comment_num = info[‘detail_info‘][‘comment_num‘] except: comment_num = None try: key_words = ‘‘ key_words_list = info[‘detail_info‘][‘di_review_keyword‘] for eachone in key_words_list: key_words = key_words + eachone[‘keyword‘] + ‘/‘ except: key_words = None try: shop_hours = info[‘detail_info‘][‘shop_hours‘] except: shop_hours = None try: alias = info[‘detail_info‘][‘alias‘] except: alias = None try: scope_type = info[‘detail_info‘][‘scope_type‘] except: scope_type = None try: scope_grade = info[‘detail_info‘][‘scope_grade‘] except: scope_grade = None try: description = info[‘detail_info‘][‘description‘] except: description = None sql = """INSERT INTO baidumap.park (park, location_lat, location_lng, address, street_id, uid, telephone, detail, tag, detail_url, type, overall_rating, image_num, comment_num, keyword, shop_hours, alias, scope_type, scope_grade, description) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s);""" cur.execute(sql, (park, location_lat, location_lng, address, street_id, uid, telephone, detail, tag, detail_url, type, overall_rating, image_num, comment_num, key_words, shop_hours, alias, scope_type, scope_grade, description,)) conn.commit() cur.close() conn.close()
