/*
|
||
|
* This CurrentUrl command attempts to produce a current_url value consistent
|
||
|
* with that returned by the Selenium WebDriver Capybara driver.
|
||
|
*
|
||
|
* It does not currently return the correct value in the case of an iframe whose
|
||
|
* source URL results in a redirect because the loading of the iframe does not
|
||
|
* generate a history item. This is most likely a rare case and is consistent
|
||
|
* with the current behavior of the capybara-webkit driver.
|
||
|
*
|
||
|
* The following two values are *not* affected by Javascript pushState.
|
||
|
*
|
||
|
* QWebFrame->url()
|
||
|
* QWebHistoryItem.originalUrl()
|
||
|
*
|
||
|
* The following two values *are* affected by Javascript pushState.
|
||
|
*
|
||
|
* QWebFrame->requestedUrl()
|
||
|
* QWebHistoryItem.url()
|
||
|
*
|
||
|
* In the cases that we have access to both the QWebFrame values and the
|
||
|
* correct history item for that frame, we can compare the values and determine
|
||
|
* if a redirect occurred and if pushState was used. The table below describes
|
||
|
* the various combinations of URL values that are possible.
|
||
|
*
|
||
|
* O -> originally requested URL
|
||
|
* R -> URL after redirection
|
||
|
* P -> URL set by pushState
|
||
|
* * -> denotes the desired URL value from the frame
|
||
|
*
|
||
|
* frame history
|
||
|
* case url requestedUrl url originalUrl
|
||
|
* -----------------------------------------------------------------
|
||
|
* regular load O O* O O
|
||
|
*
|
||
|
* redirect w/o R* O R O
|
||
|
* pushState
|
||
|
*
|
||
|
* pushState O P* P O
|
||
|
* only
|
||
|
*
|
||
|
* redirect w/ R P* P O
|
||
|
* pushState
|
||
|
*
|
||
|
* Based on the above information, we only need to check for the case of a
|
||
|
* redirect w/o pushState, in which case QWebFrame->url() will have the correct
|
||
|
* current_url value. In all other cases QWebFrame->requestedUrl() is correct.
