W5500 - http server - 401 Unauthorized How?

Question

Hi, i’m using google translate… Disassembled the example with wiz550web, transferred to the board. Now the question is how to make standard HTTP authentication (login / password)? I understand the general sense that when connecting for the first time, the server should send something like this: > Authorization const char [] = { "HTTP / 1.1 401 Authorization Required \ r \ n" "Server: MyServer \ r \ n" "WWW-Authenticate: Basic realm = \" Cloud System \ "\ r \ n" "Content Type: Text / html \ r \ n" "Content Length: 169 \ r \ n \ r \ n" " \ r \ n \ r \ n Error </ TITLE> \ r \ n" "<META HTTP-EQUIV = \" Content-Type \ "CONTENT = \" text / html; charset = ISO-8859-1 \ "> \ r \ n" "</ HEAD> \ r \ n <BODY> <H1> 401 is not authorized. </ H1> </ BODY> \ r \ n </ HTML>" }; But how to accept / process the answer, understand the password, etc.? Is there a less complete example?

I think your question is more HTTP-related than WizNet related. Have a look at this: en.wikipedia.org Basic access authentication In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials>, where credentials is the Base64 encoding of ID and password joined by a single colon :. It was originally implemented by Ari Luotonen at CERN in 1993 and defined in the HTTP 1.0 specification in 1996. ... Now, I don’t know much about HTTP, but as I see it, the client will return a request with an Authorization header, which contains the credentials. You can evaluate them and respond with 200 if everything is okay, or 401 or any other status code that fits

You’re correct, Philipp_K. The HTTP specs say, “HTTP access authentication is explained in “HTTP Authentication: Basic and Digest Access Authentication” [43]”
