百度地圖提供了開放的API，使用方法

WEB服務API

右上角登陸賬號 -> 點擊“獲取密鑰” -> “創建應用” -> 填寫應用名稱&白名單IP -> 然后復制AK(例如u2uqy7Gxui0XyBdcHLU0D3hQINLKokc0)

然后直接上代碼
API提供了3種方式

1 行政區劃區域檢索 2 圓形區域檢索 3 矩形區域檢索

詳情可見API詳情
本文以 1,3為例

import requests

url = "http://api.map.baidu.com/place/v2/search"
querystring = {"query":"市場","region":"深圳","output":"json","ak":"你的ak","page_size":20,"page_num":0}
response = requests.request("GET", url, params=querystring)
r = response.json()
print(r["results"])
print(len(r["results"]))

返回結果如下

返回20條
page_size最大為20
page_num參數可以控制頁碼數
下面是重點！

但是通過行政區地點檢索最多返回400個這是百度的限制
這時就需要通過矩形區域檢索
將深圳劃分為多個區域進行檢索
a和b的坐標在這里定位坐標拾取網站

import requests
import time
import json
keyword = "菜市場"
city = "深圳"

url = "http://api.map.baidu.com/place/v2/search"
a = "22.4717881915,113.7808575851"
b = "22.7960248910,114.3961567319"
#a為深圳左下角坐標，b為深圳右上角坐標

left_bottom = [113.7808575851,22.4717881915] # 設置區域左下角坐標（百度坐標系）
right_top = [114.3961567319,22.7960248910] # 設置區域右上角坐標（百度坐標系）

part_n = 5 # 設置區域網格（5*5）

x_item = (right_top[0]-left_bottom[0])/part_n
y_item = (right_top[1]-left_bottom[1])/part_n
n = 0 # 切片計數器
url0 = "http://api.map.baidu.com/place/v2/search?"
data = []
for i in range(part_n):
     for j in range(part_n):
         left_bottom_part = [left_bottom[0]+i*x_item,left_bottom[1]+j*y_item]; # 切片的左下角坐標
         right_top_part = [right_top[0]+i*x_item,right_top[1]+j*y_item]; # 切片的右上角坐標
         for k in range(20):
             time.sleep(0.6)
             url = url0 + "query=" + "市場" + "&page_size=20&page_num=" + str(k) + "&scope=1&bounds=" + str(
                 left_bottom_part[1]) + "," + str(left_bottom_part[0]) + "," + str(right_top_part[1]) + "," + str(
                 right_top_part[0]) + "&output=json&ak=" + "你的ak"
             print(str(left_bottom_part[1]) + "," + str(left_bottom_part[0]))
             print(str(right_top_part[1]) + "," + str(right_top_part[0]))
             print("===================================================")
             response = requests.request("GET", url)
             response = response.json()
             print(response)
             r = response["results"]
             data.append(r)

這樣就可以突破深圳區域400的限制了,可以分為1010更細化 1010共返回1200+結果

vue異步加載高德地圖

摘要：異步加載異步加載指的是為指定加載的回調函數，在的主體資源加載完畢之后，將自動調用該回調函數。幾種加載js的方式同步加載異步加載延遲加載同步加載用的最多的一種方式，又稱阻塞模式，會阻止瀏覽器的后續處理，停止后續的解析，只有當當前加載完成，才能進行下一步操作。所以默認同步執行才是安全的。但這樣如果js中有輸出document內容、修改dom、重定向等行為，就會造成頁面堵塞。...
