code execution backdoor

[di1l0o]

We found a malicious backdoor in versions 0.0.1~0.0.12 of this project, and its malicious backdoor is the request package. Even if the request package was removed by pypi, many mirror sites did not completely delete this package, so it could still be installed.When using pip install texercise -i http://pypi.doubanio.com/simple --trusted-host pypi.doubanio.com, the request malicious plugin can be successfully installed.

Repair suggestion: delete version 0.0.1~0.0.12 in PyPI, replace request with requests
