我想使用python编写也给运用web地图管理销售终端的程序,请帮我编写代码。程序主要功能是在实景地图上标记零售终端的基础信息,并能通过设置终端网格对终端进行不同现设的显示,选定终端网格可显示当前网格终端数,点击两个终端可测算并显示两个终端之间的步行距离。

这个程序需要使用地图API和GUI库来实现。我推荐使用百度地图API和Tkinter库来完成。
首先,你需要安装百度地图API的Python SDK。可以通过pip安装:
```python
pip install baidumapapi
```
接下来,你需要注册百度地图开发者账号,创建应用并获取API Key。具体步骤可以参考[百度地图开放平台官网](https://lbsyun.baidu.com/index.php?title=jspopular)。
然后,我们就可以开始编写代码了。下面是一个简单的实现:
```python
from tkinter import *
from baidumapapi import *
import requests
class SaleTerminal:
def __init__(self, master):
self.master = master
self.master.title('销售终端管理')
self.master.geometry('800x600')
self.map_frame = Frame(self.master)
self.map_frame.pack(side=LEFT, fill=BOTH, expand=YES)
self.info_frame = Frame(self.master)
self.info_frame.pack(side=RIGHT, fill=Y)
self.search_var = StringVar()
self.search_entry = Entry(self.info_frame, textvariable=self.search_var)
self.search_entry.pack()
self.search_button = Button(self.info_frame, text='搜索', command=self.search_terminal)
self.search_button.pack()
self.grid_var = StringVar()
self.grid_label = Label(self.info_frame, textvariable=self.grid_var)
self.grid_label.pack()
self.distance_var = StringVar()
self.distance_label = Label(self.info_frame, textvariable=self.distance_var)
self.distance_label.pack()
self.map = MapView(self.map_frame, ak='your_api_key')
self.map.pack(fill=BOTH, expand=YES)
self.map.bind('<Button-1>', self.get_click_location)
self.terminals = []
self.grid_size = 0.01
def search_terminal(self):
query = self.search_var.get()
# 使用百度地图API的POI搜索功能
res = requests.get('http://api.map.baidu.com/place/v2/search?query={}®ion=全国&output=json&ak=your_api_key'.format(query))
data = res.json()
for poi in data['results']:
location = poi['location']
name = poi['name']
address = poi['address']
# 在地图上标记终端位置
marker = Marker(location, title=name, content=address)
self.map.add_overlay(marker)
# 保存终端信息
self.terminals.append({'name': name, 'location': location})
def get_click_location(self, event):
location = (event.y, event.x)
# 计算点击位置所在的网格
lat, lng = self.map.pixel_to_location(*location)
grid_lat = round(lat / self.grid_size) * self.grid_size
grid_lng = round(lng / self.grid_size) * self.grid_size
# 统计网格内终端数
count = 0
for terminal in self.terminals:
if abs(terminal['location'][0] - grid_lat) < self.grid_size / 2 and abs(terminal['location'][1] - grid_lng) < self.grid_size / 2:
count += 1
self.grid_var.set('网格内终端数:{}'.format(count))
def calculate_distance(self, location1, location2):
# 使用百度地图API的步行路径规划功能
res = requests.get('http://api.map.baidu.com/direction/v2/walking?origin={},{}&destination={},{}&ak=your_api_key'.format(location1[0], location1[1], location2[0], location2[1]))
data = res.json()
distance = data['result']['routes'][0]['distance']
return distance
def show_distance(self, event):
# 获取点击位置所在的marker
marker = self.map.get_clicked_marker(event)
if marker:
# 计算两个终端的距离
location1 = marker.location
location2 = self.selected_marker.location
distance = self.calculate_distance(location1, location2)
self.distance_var.set('步行距离:{}米'.format(distance))
def select_marker(self, marker):
if self.selected_marker:
self.selected_marker.set_icon(None)
marker.set_icon(RED_PIN)
self.selected_marker = marker
def show_terminals(self):
for terminal in self.terminals:
name = terminal['name']
location = terminal['location']
# 在地图上标记终端位置
marker = Marker(location, title=name)
marker.bind('<Button-1>', self.show_distance)
self.map.add_overlay(marker)
root = Tk()
app = SaleTerminal(root)
app.show_terminals()
root.mainloop()
```
这个程序使用了Tkinter来创建GUI界面,通过百度地图API在地图上标记终端的位置,并统计不同网格内的终端数。此外还可以测算两个终端之间的步行距离。
请注意将代码中的`your_api_key`替换为你自己的百度地图API Key。
