Description

When http://something/ is written as url the GET request to the webserver doesn't contain http: instead GET //something/?SERVICE...

This causes the webserver to act as if //something/ was actually a webdirectory.

History

#1 Updated by Giovanni Manghi over 15 years ago

I'm sorry,

this is not clear to me. Could you be more specific, what component you are speaking about?

#2 Updated by skinkie - over 15 years ago

I guess the component that creates the URL for the web request?

#3 Updated by Giovanni Manghi over 15 years ago

What web request? wms?

#4 Updated by skinkie - over 15 years ago

In this case it was WMS, but I didn't test if it also happens on a WFS request.

#5 Updated by Giovanni Manghi over 15 years ago

I tested a few wms server urls (the ones added by default by qgis, among the others) by adding a trailing "/" and they work fine.

I used qgis >= 1.1

Please check it again and report back.

#6 Updated by skinkie - over 15 years ago

Did you check it in wireshark what is the actual request, not what works at a random webserver?

#7 Updated by Giovanni Manghi over 15 years ago

I'm not really into programs like wireshark, but I'll attach here the log produced by making two requests to the same server, one with the trailing slash, the other without.

Have a look and leave further feedback.

// http://www.address.bit:80), so remove that from the url before
// executing an http GET.

- QString pathAndQuery = httpurl.remove( 0, httpurl.indexOf( qurl.path() ) );

+ QgsDebugMsg( "qurl.path() is '" + qurl.path() + "'." );

+ QString pathAndQuery = httpurl.remove( 0, httpurl.indexOf( qurl.host() ) );
+ pathAndQuery = httpurl.remove( 0, pathAndQuery.indexOf( qurl.path() ) );

QgsDebugMsg( "pathAndQuery is '" + pathAndQuery + "'." );


if ( !postData ) //do request with HTTP GET {
header.setRequest( "GET", pathAndQuery );

The above fixes it, but if someone with real QT C++ skills can look at this, it would probably be better.
