Scrapy：ASCII编解码器无法编码字符

Question

I am having problem on running my crawler

UnicodeEncodeError: 'ascii' codec can't encode characters in position

I am using this code

author = str(info.css(".author::text").extract_first())

but still I am having that error any idea how can solve it? Thank you!

Here's the error

Answer 1

Try:

author = info.css(".author::text").extract_first().decode('utf-8')

The reason for this is extract_first returns a raw bytes object. To convert this to a string, python makes no guesses as to how it's encoded, therefore, you need to make that explicit. Utf-8 will handle just about anything you throw at it.
