转!python requests的content和text方法的区别

  • 问题:

一直在想requests的content和text属性的区别,从print 结果来看是没有任何区别的

看下源码:

    @property
    def text(self): """Content of the response, in unicode. If Response.encoding is None, encoding will be guessed using ``chardet``. The encoding of the response content is determined based solely on HTTP headers, following RFC 2616 to the letter. If you can take advantage of non-HTTP knowledge to make a better guess at the encoding, you should set ``r.encoding`` appropriately before accessing this property. """ #content的完整代码就不贴了。 @property def content(self): """Content of the response, in bytes."""
  • 结论是:

resp.text返回的是Unicode型的数据。

resp.content返回的是bytes型也就是二进制的数据。


也就是说,如果你想取文本,可以通过r.text。

如果想取图片,文件,则可以通过r.content。

(resp.json()返回的是json格式数据)

  • 举个栗子
# 例如下载并保存一张图片

import requests

jpg_url = 'http://img2.niutuku.com/1312/0804/0804-niutuku.com-27840.jpg'

content = requests.get(jpg_url).content

with open('demo.jpg', 'wb') as fp: fp.write(content)
