獲取高德地圖數據
第一步，開啟高德地圖：https:// map.amap.com/subway/ind ex.html
第二步，開啟開發者工具（按 F12 或 ⌥ ⌘ I ）。註意，如果你是第一次開啟，瀏覽器可能會阻止你，請允許啟動開發者許可權。
第三步，切換到 Network 分頁。第一次開啟時，這裏可能是空的。
或者也可能發現已經堆滿了非常多內容，你可以點選清空按鈕。方便等會找到想要的數據。
第四步，重新整理頁面，會發現現在已經多了好多東西了。其中我劃紅線看到的
subway.json
，就是我們要找的數據。
不過，目前預設是北京的數據。我想收集廣州的。所以，回到網頁中，切換城市。
然後發現，這裏多了2個檔。第一個的
drw_guangzhou.json
就是我要的。
第五步，把它保存到桌面，作為
subway.json
數據分析：
"l" 是一個陣列，包含了所有路線的數據，也就是網頁中這個黑色導航欄。
遍歷陣列 "l" 中的每個元素：提取 "ln" 路線名稱，"st" 也是一個陣列，裏面是所有站點的數據。然後再遍歷陣列 "st" 中的每個元素，提取裏面的 "n" 站點名稱。
OK。有了思路，就可以開始寫程式碼了。
整理地鐵路線數據
新建一個 python 檔，也放在桌面，執行它
import
json
# 地圖數據
data_file
=
'subway.json'
# 匯出的檔
output_file
=
'output.json'
# 匯入數據
json_data
=
{}
with
open
(
data_file
,
'r'
,
encoding
=
"utf-8"
)
as
file
:
json_data
=
json
.
load
(
file
)
# 整理數據
lines
=
[]
for
item
in
json_data
[
'l'
]:
line_name
=
item
[
'ln'
]
station_names
=
[
station
[
'n'
]
for
station
in
item
[
'st'
]]
lines
.
append
({
line_name
:
station_names
})
# 保存成檔
with
open
(
output_file
,
'w'
,
encoding
=
"utf-8"
)
as
file
:
json
.
dump
(
lines
,
file
,
ensure_ascii
=
False
,
indent
=
4
)
就得到了這樣一份數據

繼續擴充套件一下。
我想找出某個站點是否和其他站點有交集，也就是中轉站
篩選包含站點的路線
import json
# 前面整理好的數據
data_file = 'output.json'
# 要尋找交集的站點名稱
find_stations = '廣州東站'
# 匯入檔
with open(data_file, 'r', encoding="utf-8") as file:
data = json.load(file)
# 搜尋符合的站點資訊
lines = [line for line in data if any(find_stations in stations for stations in line.values())]
# 輸出
print(json.dumps(lines, indent=2, ensure_ascii=False))
匯出：
