当流下载时,用Response.iter_content或许更方便些。requests.get(url)默认是下载在内存中的,下载完成才存到硬盘上,可以用Response.iter_content来边下载边存硬盘 作者:朝畫夕拾链接:https://www.jianshu.com/p/6848eba

Under some specific circumstances, a loop using iter_content ends up hanging after all the content has been iterated over. Specifically, all the following conditions must be met for this to occur: You must be using Python 3 (I've tested ...
According to the documentation when stream=True iter_content(chunk_size=None) "will read data as it arrives in whatever size the chunks are received", But it actually collects all input into a single big bytes object consuming large amou...
forchunkinresponse.iter_content(chunk_size=128):# 处理chunk 上面的代码中,我们可以看到我们使用了一个for循环,以块的方式读取响应内容。这里的chunk_size参数用来设置每个块的大小。每个块使用一个缓冲区,并且当块缓冲区被填满时,它会被写入到磁盘或网络中,从而释放缓冲区。因此,这种方法可以大大减少内存占用。
