How to solve the problem that requests.gPython uses requests.get to get empty web content
How to solve the problem that requests.gPython uses requests.get to get empty web pages? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.
Let's start with an example:
Import requestsresult=requests.get ("http://data.10jqka.com.cn/financial/yjyg/")result"
Output result:
Indicates that the request has been processed successfully, and this status code is usually returned. A report of 200 means no problem.
Continue to run, it is found that a null value is returned. When crawling a web page is requested, words such as "sorry" and "unable to access" will appear in the output text information. This is the prohibition of crawling, and this problem needs to be solved through the anti-crawling mechanism. Headers is one of the ways to solve requests request anti-crawling, which is equivalent to going into the server itself of the web page and pretending that we are crawling data. For anti-crawler web pages, you can set up some headers information to simulate browsers to visit the website.
How to set up headers
Take two commonly used browsers as examples:
1 、 QQ Browser
Interface F12
Click network and type CTRL+R
Click the first one at the bottom is what we need to set it to headers to solve the problem.
2. Miscrosft edge II. Microsoft has its own browser.
Similarly, F12 opens developer tools.
Click on the network, CTRL+R
Previous code modification:
Import requestsur= "http://data.10jqka.com.cn/financial/yjyg/"headers = {'User-Agent':' Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.25 Safari/537.36 Core/1.70.3880.400 QQBrowser/10.8.4554.400'} result = requests.get (ur, headers=headers) result.text
Successfully solved the problem of unable to crawl.
