分析网页

1、查看图片地址

代码实现

<code class="language-python">import requests
import parsel
<a href="https://www.gaodaima.com/tag/url" title="查看更多关于url的文章" target="_blank">url</a> = "https://bcy.net/coser/toppost100"
response = requests.get(url=url, headers=headers)
<a href="https://www.gaodaima.com/tag/selector" title="查看更多关于selector的文章" target="_blank">selector</a> = parsel.Selector(response.text)
urls = selector.css(".rank-index-box .rank-cos-top img::attr(src)").getall()
titles = selector.css(".rank-index-box .rank-cos-avatar-box p::text").getall()
lis = zip(urls, titles)
for i in lis:
    img_url = i[0]
    title = i[1]
    response_2 = requests.get(url=img_url, headers=headers)
    path = "D:pythondemocos小姐姐img" + title + ".jpg"
    with open(path, mode="wb") as f:
        f.write(response_2.content)
        print(img_url)

图片数据是爬取下来了，但是保存数据后发现，仅仅只有20张图片，这根本不是我想要的~

所以要重新分析网页了~看一下是否有接口数据

我清空所有加载出来的数据，下拉的时候，然后出现一个神秘地址，点击去一看，果然是接口数据。为了保证准确性，咱们可以多往下翻翻

果然~~~

通过链接对比，发现接口数据的参数P是改变的，等同于页数编码，1就是对应的前20张图片数据

代码实现

<code class="language-python">import requests
for page in range(1, 6):
    url = "https://bcy.net/apiv3/rank/list/itemInfo"
    params = {
        "p": "{}".format(page),
        "ttype": "cos",
        "sub_type": "week",
        "date": "20200922",
        "_signature": "a2ovWQAAAAAem6QHkeiiVmtqL0AADQG",
    }

    headers = {
        "user-agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36"
    }
    """
    Json 接口数据
    """
    response = requests.get(url=url, params=params, headers=headers)
    html_data = response.json()
    info_list = html_data["data"]["top_list_item_info"]
    for i in info_list:
        img_url = i["item_detail"]["cover"]
        title = img_url.split("/")[-1].split("~")[0]
        response_2 = requests.get(url=img_url, headers=headers)

        path = "D:pythondemocos小姐姐img" + title + ".jpg"
        with open(path, mode="wb") as f:
            f.write(response_2.content)
            print(img_url)
