The difference between the content and text methods of python requests

Reprinted from "https://blog.csdn.net/xie_0723/article/details/51361006

 

I have been thinking about the difference between the content and text attributes of requests, and there is no difference from the print results.

Look at the source code:

    @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.""" 

 

• The conclusion is:

resp.text returns Unicode data.

What resp.content returns is bytes, that is, binary data.

---

That is, if you want to get text, you can pass r.text.

If you want to get pictures and files, you can pass r.content.

(resp.json() returns data in json format)

# 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)
---------------------------------------------------------------------------------------以下是正确的

1. Focus on understanding

response.textThe returned type isstr

response.contentThe returned type is bytes, the type can be converted to a type by a decode()methodbytesstr

It is recommended to use: response.content.decode()to get the corresponding html page

2. Expand your understanding

• response.text
  decoding type: make an educated guess on the encoding of the response based on the HTTP header, and the inferred text encoding
  How to modify the encoding method:response.encoding = 'gbk'
• response.content
  decoding type: not specified
  How to modify the encoding method:response.content.decode('utf8')
