Android使用webview获取网站源码
最近在使用webview去获取网页的源码，但是对于百度百家号的文章，网页的源代码获取出来只要标题，内容不见了，想问问有没有大佬知道这个问题。去用python直接获取的话是正常的内容，应该不是网页限制的原因。
使用python的代码
#encoding:UTF-8
import urllib
import sys
reload(sys)
sys.setdefaultencoding( "utf-8" )
url = "https://baijiahao.baidu.com/s?id=1647156988761941852&wfr=spider&for=pc"
data = urllib.urlopen(url).read()
data = data.decode('UTF-8')
def storageToLocalFiles(storagePath, data):
fhandle = open(storagePath,"wb")
fhandle.write(data)
fhandle.close()
storagePath = r'\Users\roger\Desktop\FridaHook\1.html'
storageToLocalFiles(storagePath,data)
print(data)
使用Android Studio实现的获取网页源码https://www.sportsfactbook.com
