When using http basic authentication, the username can be passed in the URL, e.g.
http://david@foo.com/path/
But now suppose the username is an email address, e.g. david@company.com. Doing this is clearly ambiguous:
http://david@company.com@foo.com/path/
Is there a way to escape the @ character in the username? I tried standard URL encoding:
http://david%40company.com@foo.com/path/
But that didn't do it.
回答1:
According to RFC 3986, section 3.2.1, it needs to be percent encoded:
userinfo = *( unreserved / pct-encoded / sub-delims / ":" )
So it looks like
http://david%40company.com@foo.com/path/
Is right. Where are you trying to read it? Maybe you need to manually decode the value?
