1. Introduction

Python calls Baidu map api, queries the latitude and longitude of the place, and writes the data into excel

2. Software environment

2.1vsCode

2.2 He liked

version: conda 22.9.0

3. Main process

3.1 Call the Baidu map api to query the latitude and longitude of the place

Create an account first After entering the Baidu map API
, create an account first. After the account is created, click the console in the upper right corner

to create an application

, and then directly run the code I pasted
. Paste the code

import requests

# 精度维度查找函数
def seekLocation(address):
    # API的URL
    url = 'http://api.map.baidu.com/geocoding/v3/'

    # 构建请求参数
    params = {
    
    
        'ak': '这块要换成自己的ak的',
        'output': 'json',
        'address': '南京航空航天大学',  # 替换为您要查询的地方名称
    }
    params['address'] = address
    # 发送GET请求
    response = requests.get(url, params=params)

    # 检查响应状态码
    if response.status_code == 200:
        # 解析返回的JSON数据
        data = response.json()
        # 检查结果状态
        if data['status'] == 0:
            # 提取经度和纬度
            location = data['result']['location']
            return location
        else:
            print('地理编码失败:', data['message'])
    else:
        print('请求出错:', response.status_code)


location = seekLocation('河南师范大学')
latitude = location['lat']
longitude = location['lng']
# 打印经度和纬度
print('经度:', longitude)
print('纬度:', latitude)

3.2 Read excel data

Just change the corresponding column

from openpyxl import load_workbook

# 打开Excel文件
workbook = load_workbook(filename='school2.xlsx')

# 选择要操作的表单
sheet = workbook['Sheet1']
column_values = []
for column in sheet.iter_cols(min_col=2, max_col=2, values_only=True):
    column_values.append(column)
print(column_values)

3.3 Write excel data

from openpyxl import load_workbook

# 打开Excel文件
workbook = load_workbook(filename='school2.xlsx')
sheet = workbook['Sheet1']
sheet.cell(row=row_index, column=8, value=value)
# 保存 Excel 文件
workbook.save(filename='school2.xlsx')
# 关闭 Excel 文件
workbook.close()

3.4 Complete code

Installation package

! pip install openpyxl
! pip install requests

the code

from openpyxl import load_workbook
import requests

# 输入学校
def seekLocation(address):
    # API的URL
    url = 'http://api.map.baidu.com/geocoding/v3/'

    # 构建请求参数
    params = {
    
    
        'ak': '换成自己的',
        'output': 'json',
        'address': '南京航空航天大学',  # 替换为您要查询的地方名称
    }
    params['address'] = address
    # 发送GET请求
    response = requests.get(url, params=params)

    # 检查响应状态码
    if response.status_code == 200:
        # 解析返回的JSON数据
        data = response.json()
        # 检查结果状态
        if data['status'] == 0:
            # 提取经度和纬度
            location = data['result']['location']
            return location
        else:
            print('地理编码失败:', data['message'])
    else:
        print('请求出错:', response.status_code)
