因此，我有一些代码可让我在“不可见”时通过URL访问我想要的任何网站。您可以在这里进入我的域：“ sm--supermechm500.repl.co/home/ViewWindow”。尝试输入“ http://youtube.com/”。 （它是不可见的，因为您无法通过历史记录返回该网站）。您会注意到该网站似乎已损坏。我所做的就是获取页面的HTML，然后完全按照其原样重新呈现它，除了标题标签。
这是有问题的python代码：
@web_site.route('/home/ViewWindow/ViewWindowResult/', methods=('GET', 'POST'))
def ViewWindowResult():
urlboi = request.values.get('url') # received through form
try:
response = urllibrequest.urlopen(urlboi)
except Exception: # attempts to open url
raise ValueError
retries = 20
while retries <= 20:
try:
htmlBytes = response.read()
except Exception: # attempts to read and retries if failed
retries =- 1
continue
else:
break
if retries > 0:
htmlstr = htmlBytes.decode("utf8")
soupedhtmlstr = BeautifulSoup(htmlstr)
sortedhtmlstr = soupedhtmlstr.prettify() # make sure code is nested correctly
sortedhtmlstr = sortedhtmlstr.replace('<head>', '<head><title>ViewWindow - Result</title>') # replace original title with "ViewWindow - Result"
return sortedhtmlstr
else: # if retries is exhausted, end attempt and lead to 500 error.
raise ValueError
也欢迎任何更改建议。
