Question

QUrl url("bword://blood transfusion");
QString res = url.toString();

Why I got the string “bword:” instead of “bword://blood transfusion”?

How can I get the string “bword://blood transfusion” form the QUrl?

Answer 1

URL syntax can be quite complex, see this Wikipedia article. The problem is that your URL does not contain authority field, it only has scheme field “bword” and path “//blood transfusion”. And according to the RFC3986 – Uniform Resource Identifier (URI): Generic Syntax:

When authority is not present, the
path cannot begin with two slash
characters (“//”).

So your URL is not valid (although isValid() returns true). Change your code to:

QUrl url("bword:/blood transfusion");
QString res = url.toString();
