使用 python 抓取 crunchbase 数据的网页

Question

Code:

import requests

response= requests.get("https://www.crunchbase.com/search/people/field/organizations/num_employees_enum/anheuser-busch")

response.raise_for_status()

webFile =open('myFile.txt', 'wb')

for chunk in res.iter_content(10000):
    webFile.write(chunk)
    webFile.close()

I found the following error:

requests.exceptions.HTTPError: 416 Client Error: Requested Range Not Satisfiable for url: https://www.crunchbase.com/search/people/field/organizations/num_employees_enum/anheuser-busch

Answer 1

If you remove the line response.raise_for_status() you will receive the following output from crunchbase:

Pardon Our Interruption...

As you were browsing www.crunchbase.com something about your browser made us think you were a bot. There are a few reasons this might happen:

• You're a power user moving through this website with super-human speed.
• You've disabled JavaScript in your web browser.
• A third-party browser plugin, such as Ghostery or NoScript, is preventing JavaScript from running. Additional information is available in this support article.

In fact, you are a bot, instead of Python requests you should try using their own API.

EDIT

To use the crunchbase API, you need to register here: https://about.crunchbase.com/solutions/ the free basic access licence should be enough to access organizations according the documentation.

Once you have registered you will have a user API key, then you can make your requests as follows:

https://api.crunchbase.com/v3.1/organizations?user_key=[user_key]

The equivalent to the query you made using the API would be something like this:

import json,requests

url = "https://api.crunchbase.com/v3.1/organizations/anheuser-busch"

params = dict(user_key="your_key")

resp = requests.get(url=url, params=params)
data = json.loads(resp.text)

webFile = open('myFile.txt', 'w')

for organization in data:
    webFile.write(organization["num_employees_max"])

webFile.close()

Haven't tested it myself but it should get you going.

Here is all the data available for organizations: https://data.crunchbase.com/docs/organization
