Question

我去年为一个Python项目编写了此货币转换代码。我再次运行它并确保它仍然可以工作，因为我想将其作为Github上的项目列出，但是我收到了HTTPError：Forbidden。我已经搜索并找到了其他与此相关的帖子，但是这些帖子都没有为我工作。有什么方法可以使用我拥有的内容从相同的URL进行抓取吗？还是我需要在没有urllib的情况下重新编写它，因为我知道它可以防止由于漫游器的影响（从我读过的与此主题相关的其他一篇文章中了解到）。

代码：

    ognumber = str
    import urllib.request

    while True:
        ogcurrency = str((input("What is the original currency? "))).upper()
        newcurrency = str((input("What currency do you want to convert to? ")))\
        .upper()
        # Asks the first two questions

            while True:
                ognumber_str = input("How much do you want to convert (int)? ")
                    # Asks how much needs to be converted
                if(ognumber_str.isdigit()):
                    ognumber_int = int(ognumber_str)
                    break
                    # if the is str is an integer, continue, if not, ask to try again
                else:
                    print("The value you input must be an integer. Please try again.")


            if ognumber_str != str:

                url = \
                "https://finance.google.com/finance/converter?a={:d}&from={:s}&to={:s}\
                ".format(ognumber_int, ogcurrency, newcurrency)
                    # calls to conversion api
                response = urllib.request.urlopen(url)
                result = str(response.read())

                index_back = result.find("</span") #end of api we want
                index = result.find("span") #beginning of api section we want
                index_s = result[index+15:index_back] #spliced more
                index_flt = float(index_s[:-4]) #the floating integer values of the str

                index_currency = index_s[-3:] # string of the currency
                print("{} {} is {:.2f} {}".format(ognumber_int, ogcurrency, index_flt,\
          index_currency)) #formatting for expected final result


                leave = input("Do you want to convert another currency? ").upper()
                #input no in any format to leave the program

                if leave == "NO":
                    break

                else:
                    continue

错误：
