    Crawlers generally can only crawl data from web pages. The usage of ofo can only be counted within the program.

    I guess he is a fellow graduate student

    Crawler crawls data on existing web pages to replace manual data screening. So you first need to find the source of usage. I just checked the ofo official website and there is no relevant real-time data released.
    Or you can try to narrow the sample and make a questionnaire. .
