求教用 requests 库写下载脚本问题

    代码如下

    r = requests.get(url,  stream = True,timeout = 10)
    stream_size = r.headers['Content-Length'] #获取下载文件大小
    with open(name + '.mp4', 'wb') as f:
        for chunk in r.iter_content(chunk_size = 1024):
        f.write(chunk) #有时候会卡在这里,即一直在等待下一个 chunk。
    
    

    有时候下载视频,服务器不会返拒绝超时之类的错误(能返回错误倒是好解决),但就是不返回下个 chunk 数据,一直等啊等 所以脚本有时候就卡在那不动了,有办法避免这种情况吗? 获取下个 chunk 值这一段可以加上 timeout 的阈值吗?
