Html 不能刮<；div id="；搜索容器“&燃气轮机；来自pdb数据库网站

我是网络垃圾新手，尝试访问pdb网页上的每个pdb ID，例如：

url= https://www.rcsb.org/search?request=%7B%22query%22%3A%7B%22parameters%22%3A%7B%22attribute%22%3A%22rcsb_entity_source_organism.rcsb_gene_name.value%22%2C%22operator%22%3A%22exact_match%22%2C%22value%22%3A%22MCF3%22%7D%2C%22type%22%3A%22terminal%22%2C%22service%22%3A%22text%22%2C%22node_id%22%3A0%7D%2C%22return_type%22%3A%22entry%22%2C%22request_options%22%3A%7B%22pager%22%3A%7B%22start%22%3A0%2C%22rows%22%3A100%7D%2C%22scoring_strategy%22%3A%22combined%22%2C%22sort%22%3A%5B%7B%22sort_by%22%3A%22score%22%2C%22direction%22%3A%22desc%22%7D%5D%7D%2C%22request_info%22%3A%7B%22src%22%3A%22ui%22%2C%22query_id%22%3A%22c75bbf18a058a812f5384f297528d4b6%22%7D%7D

在这里，我试图获得像

“3ZBF”

和

“4UXL”

这样的ID

我写了下面的代码：

url='https://www.rcsb.org/search?request=%7B%22query%22%3A%7B%22parameters%22%3A%7B%22attribute%22%3A%22rcsb_entity_source_organism.rcsb_gene_name.value%22%2C%22operator%22%3A%22exact_match%22%2C%22value%22%3A%22MCF3%22%7D%2C%22type%22%3A%22terminal%22%2C%22service%22%3A%22text%22%2C%22node_id%22%3A0%7D%2C%22return_type%22%3A%22entry%22%2C%22request_options%22%3A%7B%22pager%22%3A%7B%22start%22%3A0%2C%22rows%22%3A100%7D%2C%22scoring_strategy%22%3A%22combined%22%2C%22sort%22%3A%5B%7B%22sort_by%22%3A%22score%22%2C%22direction%22%3A%22desc%22%7D%5D%7D%2C%22request_info%22%3A%7B%22src%22%3A%22ui%22%2C%22query_id%22%3A%22c75bbf18a058a812f5384f297528d4b6%22%7D%7D'

page = requests.get(url)

data = page.text

soup = BeautifulSoup(data, "html.parser")

tex_tag= soup.find('div',{"class":"container","id":"maincontentcontainer"})

new_line=tex_tag.find("div",{"id":"search-container"})

print(new_line)

print(tex_tag.prettify())

在这里，我看不到

的内部。我已经检查了网页上的html文件，pdb id位于

中

你能给我一个解决方案，或者给我一个如何解决这个问题的见解吗

先谢谢你

此站点使用API在呈现结果之前获取结果。它来自以下url：

POST https://www.rcsb.org/search/gql

在JSON输入中传递标识符列表时：

import requests

ids = ["3ZBF","4UXL"]

r = requests.post("https://www.rcsb.org/search/gql",
    json = {
        "attributes": None,
        "identifiers": ids,
        "returnType": "entry",
        "report": "search_summary"
    })

print(r.json()) 

---

此脚本将根据您的搜索URL打印所有标识符：

import json
import requests
import urllib.parse


url = 'https://www.rcsb.org/search?request=%7B%22query%22%3A%7B%22parameters%22%3A%7B%22attribute%22%3A%22rcsb_entity_source_organism.rcsb_gene_name.value%22%2C%22operator%22%3A%22exact_match%22%2C%22value%22%3A%22MCF3%22%7D%2C%22type%22%3A%22terminal%22%2C%22service%22%3A%22text%22%2C%22node_id%22%3A0%7D%2C%22return_type%22%3A%22entry%22%2C%22request_options%22%3A%7B%22pager%22%3A%7B%22start%22%3A0%2C%22rows%22%3A100%7D%2C%22scoring_strategy%22%3A%22combined%22%2C%22sort%22%3A%5B%7B%22sort_by%22%3A%22score%22%2C%22direction%22%3A%22desc%22%7D%5D%7D%2C%22request_info%22%3A%7B%22src%22%3A%22ui%22%2C%22query_id%22%3A%22c75bbf18a058a812f5384f297528d4b6%22%7D%7D'
search_link = 'https://www.rcsb.org/search/data'

json_data = url.split('=')[-1]
json_data = json.loads(urllib.parse.unquote(json_data))

data = requests.post(search_link, json=json_data).json()

# uncomment this to print all data:
# print(json.dumps(data, indent=4))

for r in data['result_set']:
    print(r['identifier'])

印刷品：

3ZBF
4UXL

感谢您的回复，我的目的是找出pdb ID，逐个输入基因名称。我不知道pdb ID，我只想输入基因名来提取它们。因此，我尝试使用网页抓取。你有什么建议给我吗？提前谢谢，非常感谢。你帮了大忙。
