Hi there!
I met this error when using Baidu. Google and Bing are fine.
Is there anything that can fix this?

@chinasilva This will yield JSONDecodeError:

After trying, I find that the following headers work:

headers = {
    'Accept-Language': 'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
    'User-Agent':
    ('Mozilla/5.0 (Windows NT 10.0; Win64; x64)'
     'AppleWebKit/537.36 (KHTML, like Gecko)'
     'Chrome/88.0.4324.104 Safari/537.36'),
}

[simonmcnair]

is an example of how to do this as follows ?

baidu_crawler = BaiduImageCrawler(storage={'root_dir': folder2})
baidu_crawler.session.headers= {
    'Accept-Language': 'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
    'User-Agent':
    ('Mozilla/5.0 (Windows NT 10.0; Win64; x64)'
     'AppleWebKit/537.36 (KHTML, like Gecko)'
     'Chrome/88.0.4324.104 Safari/537.36'),
}
baidu_crawler.crawl(keyword=lookfor, offset=0, max_num=1000,
                    min_size=(512,512), max_size=None)

I do not think the answer is adding Accept-Encoding: gzip, deflate, br

Looks like this uses urllib3. urllib3 can import brotli if you have it installed. I assume brotli would add the "br". Otherwise Accept-Encoding: gzip, deflate, br says I can handle GZIP, ZIP (deflate) and brotli responses. If you do not have brotli, you may get a garbage response.

urllib3 Response

Accept-Language may work, since most users prefer a specific language. Default headers, other than User-Agent:

'Accept-Encoding': 'gzip, deflate'
'Accept': '*/*'
`'Connection': 'keep-alive'``

And this is what my Firefox 121 sends:

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br

I would recommend testing to find the minimal requirement for bypassing Baidu problems.

Hi there! I met this error when using Baidu. Google and Bing are fine. Is there anything that can fix this?

The response text I got when I see this error is this JSON. In this and another project:

{"antiFlag":1,"message":"Forbid spider access","bfe_log_id":"xxxxxx random numbers xxxxxx"}

The correct answer is probably what @liyufan posted, to send something that Baidu would expect from a real person. This should be an option somewhere, but I think Chinese and English is what Baidu expects. @simonmcnair looks correct to me.
