- 問題:
一直在想requests的content和text屬性的區別,從print 結果來看是沒有任何區別的
看下源碼:
@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的完整代碼就不貼了。 @property def content(self): """Content of the response, in bytes."""
- 結論是:
resp.text返回的是Unicode型的數據。
resp.content返回的是bytes型也就是二進制的數據。
也就是說,如果你想取文本,可以通過r.text。
如果想取圖片,文件,則可以通過r.content。
(resp.json()返回的是json格式數據)
舉個栗子
# 例如下載並保存一張圖片 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)
