Python Requests库报错：ValueError: Invalid header value - 解决HTTP请求头错误

The error is caused by an invalid header value in the request. Specifically, the value of the header contains non-ASCII characters or invalid characters that are not allowed in HTTP headers. The header value is a cookie string that contains various key-value pairs separated by semicolons. One possible solution is to encode the header value using a proper encoding method, such as UTF-8, before setting it in the request headers. Another solution is to remove the invalid characters or non-ASCII characters from the header value.
