Question

我试图使用这个Python模块。 https://github.com/coursera-dl/edx-dl

请原谅我的基本知识。

然后安装Anaconda 3 Windows 10：

pip install edx-dl

pip install --upgrade youtube-dl

然后去做课程：

edx-dl -u user@user.com --list-courses

edx-dl -u user@user.com COURSE_URL

然而，一旦实际开始下载，这一切都有效：收到SSL /连接错误：HTTP Error 403: Forbidden

Fiddler表示，由于User-Agent

，它被Cloudfare所阻止

我安装了Fake_UserAgent https://pypi.python.org/pypi/fake-useragent并添加了：

from fake_useragent import UserAgent #added this


def edx_get_headers():
    """
    Build the Open edX headers to create future requests.
    """
    logging.info('Building initial headers for future requests.')

    headers = {
        'User-Agent': 'edX-downloader/0.01',
        'Accept': 'application/json, text/javascript, */*; q=0.01',
        'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8',
        'Referer': EDX_HOMEPAGE,
        'X-Requested-With': 'XMLHttpRequest',
        'X-CSRFToken': _get_initial_token(EDX_HOMEPAGE),
    }

    ua = UserAgent()   #added this
    headers['User-Agent'] = ua.ie #added this

然后它下载了一个pdf和一个xls，但由于request.py添加了一个标题，因此添加了一个标题，因此添加了一个标题，因此在request.py中添加了假名，并注释掉了默认标题，如下所示。

from fake_useragent import UserAgent
        ub = UserAgent()
        self.addheaders = [('User-Agent', ub.ie)] 
        # self.addheaders = [('User-Agent', self.version), ('Accept', '*/*')] [('User-Agent', self.version), ('Accept', '*/*')]

新错误如下。我无法解决如何进一步排查问题的方法。我怀疑它无法找到可能由Windows引起的文件/路径。

同样的问题，但是没有提供任何解决方案或协助，所以我想在此尝试。

有关如何学习如何解决此问题的建议将不胜感激。

Answer 1

调试代码，发现无法找到youtube-dl。

检查回声%PATH%并意识到我有路径：

C:...\Anaconda3\但不是C:...\Anaconda3\Scripts\ (this is location of youtube_dl.exe)。

我添加了此路径但未重新启动。

重新启动并立即解决。

Answer 2

还有另一种简单的解决方案，无需使用Fake_UserAgent，只需使用其他下载器，例如wget。

安装新的edx_dl。

如果您在Windows上下载wget，则将其保存在例如H驱动器上。

像这样更改download_url函数：

def download_url(url, filename, headers, args):
    """
    Downloads the given url in filename.
    """

    if is_youtube_url(url):
        download_youtube_url(url, filename, headers, args)
    else:
    # jcline
        cmd = (["h:\wget.exe", url, '-c', '-O', filename, '--keep-session-cookies', '--no-check-certificate'])
        execute_command(cmd, args)

系统找不到`edx-dl`模块中指定的文件
