requests的get类型请求params参数中存在百分号‘%’的解决办法

在使用requests中难免需要对URL进行请求，今天遇到这样一条URL： http://127.0.0.1/?test=%25test 凭经验，我使用requests.get进行请求，并把参数写入params中：

>>> import requests >>> url = 'http://127.0.0.1' >>> params = { 'test':'%25test' } >>> r = requests.get(url, params = params) # 使用nc接收请求while true; do echo -e "HTTP/1.1 200 OK\n\n ❤" | nc -l -p 8080 -q 1; done GET /?test=%2525test HTTP/1.1 Host: 127.0.0.1:8080 User-Agent: python-requests/2.23.0 Accept-Encoding: gzip, deflate Accept: */* Connection: keep-alive

可以看到nc输出的url为 /?test=%2525test而非 /?test=%25test 搜索相关资料后发现，URL中的百分号是个特殊字符，用来对需要进行百分号编码的字符的ASCII码进行转义，具体参考维基百科 python的requests库会将params中的百分号进行转义所以解决办法就是禁止对%进行编码

>>> import requests >>> from urllib.parse import unquote >>> url = 'http://127.0.0.1' >>> params = { 'test':'%25test' } >>> params['test'] = unquote(params['test']) >>> r = requests.get(url, params = params) # 使用nc接收请求while true; do echo -e "HTTP/1.1 200 OK\n\n ❤" | nc -l -p 8080 -q 1; done GET /?test=%25test HTTP/1.1 Host: 127.0.0.1:8080 User-Agent: python-requests/2.23.0 Accept-Encoding: gzip, deflate Accept: */* Connection: keep-alive

注：正常的URL中百分号都是作为转义字符出现，所以如果出现了百分号，只需要把‘%xx’替换为其转义后的字符即可🤦🏼‍♂️

http://127.0.0.1/?test=%25test >>> url = 'http://127.0.0.1' >>> params = { 'test':'%test' }
