正在更新数据库,但是今日限额到了,api接口不能用了,数据表只更新了一半。
期间遇到了很多问题,经过问同学,和查资料解决了。
上一篇博客的获取单个地址比较好用,批量获取的时候就不太行了。
这是地域与行政代码的截图:
主要代码:
获取经纬度:
def JingWei(address): global lat, lng # 产生sn码 queryStr = "/geocoding/v3/?address=" + address + '&output=json&ak=' + MyAK encodedStr = urllib.parse.quote(queryStr, safe="/:=&?#+!$,;'@()*[]") rawStr = encodedStr + MySK sn = (hashlib.md5(urllib.parse.quote_plus(rawStr).encode("utf8")).hexdigest()) # 生成url url = urllib.parse.quote("http://api.map.baidu.com" + queryStr + "&sn=" + sn, safe="/:=&?#+!$,;'@()*[]") #print('Retrieving', url) # 从API读取数据 uh = urllib.request.urlopen(url) data = uh.read().decode() # print('Retrieved', len(data), 'characters') # 解析数据 try: js = json.loads(data) except: js = None try: if not js or 'status' not in js or js['status'] != 0: print('======Failure====') print(data) # print(json.dumps(js, indent=4, ensure_ascii=False)) # 获取经纬度坐标和地址类型 lat = js["result"]["location"]["lat"] lng = js["result"]["location"]["lng"] #print('纬度', lat, '经度', lng) level = js["result"]["level"] #print('地址类型', level) except: pass
逆向解析:
def getlocation(lat, lng): url = '/reverse_geocoding/v3/?ak=' + MyAK + '&output=json&coordtype=wgs84ll&location=' + str(lat) + ',' + str(lng) encodedStr = urllib.parse.quote(url, safe="/:=&?#+!$,;'@()*[]") rawStr = encodedStr + MySK sn = (hashlib.md5(urllib.parse.quote_plus(rawStr).encode("utf8")).hexdigest()) # 生成url url = urllib.parse.quote("http://api.map.baidu.com" + url + "&sn=" + sn, safe="/:=&?#+!$,;'@()*[ ]") # print('Retrieving', url) req = urllib.request.urlopen(url) # json格式的返回数据 res = req.read().decode("utf-8") # 将其他编码的字符串解码成unicode #print(json.loads(res)) return json.loads(res)
def jsonFormat(addr,lat, lng): print(addr) str = getlocation(lat, lng) global dictjson dictjson = {} # get()获取json里面的数据 jsonResult = str.get('result') address = jsonResult.get('addressComponent') # 国家 country = address.get('country') # 国家编号(0:中国) country_code = address.get('country_code') # 省 province = address.get('province') # 城市 city = address.get('city') # 城市等级 city_level = address.get('city_level') # 县级 district = address.get('district') # 区划代码 adcode = address.get('adcode') # 街道 street = address.get('street') # 街道编号 street_number = address.get('street_number') # 把获取到的值,添加到字典里(添加) # dictjson['country']=country # dictjson['country_code'] = country_code # dictjson['province'] = province + city + district + street + street_number #dictjson['province'] = province + city + district #dictjson['adcode'] = adcode province=province + city + district db.update_db(addr,'地域',province) db.update_db(addr, '行政代码', adcode) # with open('D:\\workspace\\pycharm\\region\\adcode.json', 'a',encoding='utf-8') as f: #json.dump(dictjson, f,ensure_ascii=False) try: conn = connect(host='localhost', port=3306, database='kettle', user='root', password='1234', charset='utf8') cs = conn.cursor() sql = "update exam12 set 地域='"+province+"' where 完成单位='"+addr+"'" cs.execute(sql) except: pass #return dictjson # dictjson['city_level'] = city_level # dictjson['district']=district
