问题 As I understand, when you are building a http response in node/express or whatever, the process consists of primarily two non-sequential steps: defining Headers and constructing the body. Headers include Set-Cookie headers. In Express, the following methods are available with the response object for setting headers: res.append(); // To append/create headers res.cookie(); // A convenience method to append set-cookie headers. As headers are only buffered and not actually sent until the response

It is often linked to the Basic authentication scheme as per RFC 7617, but that is not a given. The Basic scheme allows clients to provide a username-password-pair separated by a colon ( : ) coded in Base64. It cannot be

问题 Where is the HTTP/1.1 mandatory Host header field in HTTP request messages generated by the requests Python library? import requests response = requests.get("https://www.google.com/") print(response.request.headers) Outputs this: {'User-Agent': 'python-requests/2.22.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive'} 回答1: The HOST header is not being added to the request by requests by default. If it is not explicitly added then the decision is delegated to
