Question

这是我的代码：

def getGif(request):
    import time
    import giphy_client
    from giphy_client.rest import ApiException
    from pprint import pprint

    # create an instance of the API class
    api_instance = giphy_client.DefaultApi()
    api_key = 'dc6zaTOxFJmzC'  # str | Giphy API Key.

    # ASK FOR USER INPUT TO ALTER THE QUERY
    q = input("What gifs would you like to find? ")


    limit = 25  # int | The maximum number of records to return. (optional) (default to 25)
    offset = 0  # int | An optional results offset. Defaults to 0. (optional) (default to 0)
    rating = 'g'  # str | Filters results by specified rating. (optional)
    lang = 'en'  # str | Specify default country for regional content; use a 2-letter ISO 639-1 country code. See list of supported languages <a href = \"../language-support\">here</a>. (optional)
    fmt = 'json'  # str | Used to indicate the expected response format. Default is Json. (optional) (default to json)

    try:
        # Search Endpoint
        api_response = api_instance.gifs_search_get(api_key, q, limit=limit, offset=offset, rating=rating, lang=lang,
                                                fmt=fmt)
        # pprint
        img = requests.get(api_response.data[0].images.fixed_height_downsampled.url)
        return HttpResponse(img,content_type='image/gif')
    #return HttpResponse(api_response.data[0].images.fixed_height_downsampled.url, content_type="application/json")
    except ApiException as e:
        print("Exception when calling DefaultApi->gifs_search_get: %s\n" % e)

然后我运行了它，但是除了这样的空白之外，终端上什么都没有显示： blank space

请帮助！！：<< / p>

Answer 1

问题出在for循环中，您必须从i而不是name_list_item提取内容。

您的工作代码应如下所示：

import requests
from bs4 import BeautifulSoup

page = requests.get('https://web.archive.org/web/20121007172955/https://www.nga.gov/collection/anZ1.htm')
soup = BeautifulSoup(page.text, 'html.parser')

name_list = soup.find(class_='BodyText')
name_list_item = name_list.find_all('a')

for i in name_list_item:
  names = i.contents[0]
  print(names)

Answer 2

我建议您使用以下方法获取链接。（实际上，您的解决方案的问题在于，它还包含我们不想要的无效数据，您可以打印和检查）。有names类型的32个<class 'bs4.element.NavigableString'>没有内容，因此它正在打印32个LF（ASCII值10）字符。
