Indiegogo website URL crawling failed: How to troubleshoot various errors in Python crawler code?
Apr 01, 2025 pm 07:24 PMIndiegogo website product URL crawling failed: Detailed explanation of Python crawler code debugging
This article analyzes the problem of failing to crawl the product URL of Indiegogo website using Python crawler scripts and provides detailed troubleshooting steps. The user code tries to read product information from the CSV file, splice it into a complete URL, and crawl it using multiple processes. However, the code encountered the "put chromedriver.exe into chromedriver directory" error, and the crawling still failed even after chromedriver is configured.
Analysis of the root cause of the problem and solutions
The initial error prompted that chromedriver was not configured correctly and was resolved. However, the root cause of crawling failure may not be so simple, and there are mainly the following possibilities:
-
URL splicing error: The original code
df_input["clickthrough_url"]
returns a pandas Series object, not a directly iterable sequence of elements. The modifieddf_input[["clickthrough_url"]]
returns a DataFrame, and it still cannot be directly iterated. The correct modification method is as follows:def extract_project_url(df_input): return ["https://www.indiegogo.com" ele for ele in df_input["clickthrough_url"].tolist()]
This converts Series into a list for easy iterative stitching.
-
Website anti-crawler mechanism: Indiegogo is likely to enable anti-crawler mechanisms, such as IP ban, verification code, request frequency limit, etc. Coping method:
- Use proxy IP: Hide the real IP address to avoid being blocked.
- Set reasonable request headers: simulate browser behavior, such as setting
User-Agent
andReferer
. - Add delay: Avoid sending a large number of requests in a short time.
CSV data problem: The
clickthrough_url
column in the CSV file may have a malformed format or missing value, resulting in URL splicing failure. Carefully check the quality of CSV data to ensure that the data is complete and formatted correctly.Custom
scraper
module problem: There may be errors in the internal logic ofscrapes
function ofscraper
module, and the HTML content returned by the website cannot be correctly processed. The code of this function needs to be checked to make sure it parses the HTML correctly and extracts the URL.Chromedriver version compatibility: Make sure the Chromedriver version exactly matches the Chrome browser version.
Cookie problem: If Indiegogo needs to log in to access product information, it is necessary to simulate the login process and obtain and set necessary cookies. This requires more complex code, such as using the
selenium
library to simulate browser behavior.
Suggestions for troubleshooting steps
It is recommended that users follow the following steps to check:
- Verify URL splicing: Use the modified
extract_project_url
function to print the generated URL list to confirm its correctness. - Check CSV data: Double-check the CSV file to find errors or missing values ??in the
clickthrough_url
column. - Test a single URL: Use the
requests
library to try to crawl a single URL and check whether the page content can be successfully obtained. Observe the response status code of the network request. - Add request header and delay: Add
User-Agent
andReferer
to the request and set reasonable delays. - Using Proxy IP: Try to crawl using Proxy IP.
- Check the
scraper
module: Double-check the code ofscraper
module, especially the logic ofscrapes
function. - Consider cookies: If none of the above steps are valid, you need to consider whether the website needs to be logged in and try to simulate the login process.
By systematically checking the above problems, users should be able to find and solve the reasons for the failure of the URL crawling of the Indiegogo website. Remember, the anti-crawler mechanism of the website is constantly updated and requires flexible adjustment of strategies.
