cesium紐約3dtiles數據下載

cesium示例有紐約的3dtiles數據，下載官方有下載連接，可是下載後爲亂碼。html
所以研究了下，寫了個爬蟲解碼下載，使用辦法，安裝Python直接運行便可，代碼以下：python
#coding=utf-8
from urllib import request import os import socket import zlib # python版本3.7 # 設置超時
socket.setdefaulttimeout(60) def mkdir(path): # 去除首位空格
    path=path.strip() # 去除尾部 \ 符號
    path=path.rstrip("\\") # 判斷路徑是否存在
    # 存在 True
    # 不存在 False
    isExists=os.path.exists(path) # 判斷結果
    if not isExists: # 若是不存在則建立目錄
        # 建立目錄操做函數
 os.makedirs(path) print('path create success!') return True else: # 若是目錄存在則不建立，並提示目錄已存在
        print('path already exist!') return False # 定義要建立的目錄
mkpath="F:\\python\\cesiumData\\"
# 調用函數 #mkdir(mkpath)

def callbackfunc(blocknum, blocksize, totalsize): '''回調函數 @blocknum: 已經下載的數據塊 @blocksize: 數據塊的大小 @totalsize: 遠程文件的大小 '''
    # percent = 100.0 * blocknum * blocksize / totalsize
    # if percent > 100:
        # percent = 100
    print("--") #便利URL，獲取數據
