QAbstractUriResolver ¶

QAbstractUriResolver class is a callback interface for resolving Uniform Resource Identifiers. A Uniform Resource Identifier (URI) is a string that uniquely identifies a resource. URIs are versatile global identifiers. It is often useful to transform a URI that identifies something logical into a URI that locates something physical (a URL), or to simply map a URI to a different URI. resolve() provides this functionality. 更多 …

详细描述 ¶

For example, one could write a QAbstractUriResolver subclass that rewrites library ISBN number URIs as book title URLs, e.g., urn:isbn:0-345-33973-8 would be rewritten as file:///books/returnOfTheKing.doc . Or a QAbstractUriResolver subclass could be written for a web browser to let the web browser protect the user’s private files by mapping incoming requests for them to null URIs.

QObject

构造 QAbstractUriResolver with the specified parent .

PySide2.QtXmlPatterns.QAbstractUriResolver. resolve ( relative , baseURI ) ¶

参数

relative – QUrl
baseURI – QUrl

返回类型

QUrl

返回 relative URI resolved using the baseURI .

The caller guarantees that both relative and baseURI are valid, and that baseURI is absolute. relative can be relative, absolute, or empty.

返回的 QUrl can be a default constructed QUrl . If it is not a default constructed QUrl , it will be absolute and valid. If a default constructed QUrl is returned, it means the relative URI was not accepted to be resolved.

If the reimplemented function decides it has nothing to do about resolving the relative URI, it should simply return the relative URI resolved against the baseURI , i.e.:

											return baseURI.resolved(relative);
