python - python-requests 可以像 curl 一样直接获取 url 到磁盘上的文件句柄吗？

Question

curl 有一个选项可以直接将文件和头数据保存在磁盘上:

curl_setopt($curl_obj, CURLOPT_WRITEHEADER, $header_handle);
curl_setopt($curl_obj, CURLOPT_FILE, $file_handle);

python-requests 有同样的能力吗？

Answer 1

据我所知，requests 没有提供将内容保存到文件的功能。

import requests

with open('local-file', 'wb') as f:
    r = requests.get('url', stream=True)
    f.writelines(r.iter_content(1024))

参见 request.Response.iter_content documentation .

iter_content(chunk_size=1, decode_unicode=False)

Iterates over the response data. When stream=True is set on the request, this avoids reading the content at once into memory for large responses. The chunk size is the number of bytes it should read into memory. This is not necessarily the length of each item returned as decoding can take place.
