Indiegogo website URL crawling failed: How to troubleshoot code and data problems?

Indiegogo website product URL crawling failed and solutions

This article analyzes the problem of failed crawling product URLs from Indiegogo website and provides detailed troubleshooting steps and solutions. The code tries to get the product URL from Indiegogo but it ends up failing.

The problem stems from the way df_input["clickthrough_url"] column is handled in extract_project_url function. The original code assumes that the column contains the available URL directly and tries it with https://www.indiegogo.com . However, the actual situation may be more complicated, and the data in the clickthrough_url column may contain a complete URL, or may only contain URL fragments, or even extra characters or spaces.

The wrong code modification for ele in df_input[["clickthrough_url"]]: Trying to solve the problem by modifying the loop, but in fact, df_input[["clickthrough_url"]] returns a DataFrame containing the column, not the column's value itself, so the loop is still invalid.

The root cause of crawling failure may not be just a code loop error, but also includes the following aspects:

  • Data format problems: 1.csv The "clickthrough_url" column data in the csv file may have format problems, such as containing extra spaces, special characters or newlines, resulting in URL splicing errors. The content of the CSV file needs to be carefully checked to ensure that the data is complete and standardized.

  • Website anti-climbing mechanism: Indiegogo may enable anti-climbing mechanisms, such as IP blockade or verification code. Solutions include using proxy IP, setting reasonable request headers (User-Agent, etc.), and complying with the website robots.txt rules.

  • Network Connection Problems: Unstable network connections can also cause crawling failures. Ensure stable and reliable network connection.

  • Custom scraper module problem: Custom scraper modules may have internal errors, causing URL acquisition or processing to fail. The code of this module needs to be carefully checked to ensure that it functions properly.

The correct extract_project_url function needs to be adjusted according to the actual situation of the "clickthrough_url" column data in 1.csv . If the column contains a complete URL, there is no need to splice it; if the URL fragment is included, it needs to splice it according to the actual situation, and pay attention to cleaning up unnecessary spaces and special characters. Methods such as regular expressions can be used to extract URLs more accurately.

Suggested solutions:

  1. Check 1.csv data: Double check the data format of the "clickthrough_url" column to clean up unnecessary characters.

  2. Modify extract_project_url function: According to the result of step 1, modify the function to correctly handle the URL. Add error handling mechanisms (such as try-except statements) to catch and handle exceptions.

  3. Handling anti-crawling mechanism: If the problem persists, consider using proxy IP and setting request headers.

  4. Check the scraper module: Check the code of the custom module to make sure it functions correctly.

  5. Debugging code: Use debugging tools to gradually track the code execution process and find out the specific location of the error.

Simple loop modifications cannot solve the fundamental problem. You need to systematically check the data, code and network environment to find and solve the root cause of crawling failure.
