`requests.utils.get_encoding_from_headers` assumes that the charset parameter always specifies a name. In very rare cases a server can send a malformed content-type header which does not specify a name. In these cases, requests should probably just treat it as if no charset had been specified. ## Expected Result `requests.utils.get_encoding_from_headers({'content-type': 'text/html; charset'}) == 'ISO-8859-1'` ## Actual Result ``` File ~/opt/anaconda3/2023.03/envs/mamba/envs/py3/lib/python3.9/site-packages/requests/utils.py:553, in get_encoding_from_headers(headers) 550 content_type, params = _parse_content_type_header(content_type) 552 if "charset" in params: --> 553 return params["charset"].strip("'\"") 555 if "text" in content_type: 556 return "ISO-8859-1" AttributeError: 'bool' object has no attribute 'strip' ``` ## System Information ```json { "chardet": { "version": "4.0.0" }, "charset_normalizer": { "version": "2.0.4" }, "cryptography": { "version": "41.0.3" }, "idna": { "version": "3.4" }, "implementation": { "name": "CPython", "version": "3.9.15" }, "platform": { "release": "5.14.0-284.11.1.el9_2.x86_64", "system": "Linux" }, "pyOpenSSL": { "openssl_version": "1010116f", "version": "23.2.0" }, "requests": { "version": "2.31.0" }, "system_ssl": { "version": "1010117f" }, "urllib3": { "version": "1.26.18" }, "using_charset_normalizer": false, "using_pyopenssl": true } ```
