414 Request URI Too Large

 

hello, I am using Selenium RC on Firefox 2.0.0.14 on FreeBSD 6.2 with JRE 1.6.

 

 

When I am trying to fill some text fields longer than lets say 1000 characters, i get following error:  414 Request URI Too Large.

 

 

I assume that is due to the fact that Selenium driver (i mean main window which drives the child frame or child window) is being question with GET requests, and those request seem to be too large, is there any solution for this?

 

 

 

 

Regards, T. Kraus

Re: 414 Request URI Too Large

Okay, since there is no responses :P I had to hack it on my own.

 

This horrendal limit is due to Jetty FIXED non-modificable limit for max GET request.

Workaround for perl is splitting in chunks(same as somebody done with Python already)

My code ( i changed the function "type" in Selenium.pm) :


sub type {
    my $self = shift;
    my ($Locator, $Value) = @_;
    my $MaxChars = 2000;
    my $ValLen = length $Value;
    if ($ValLen > $MaxChars) {
        my $Pos = 0;
        while ($Pos < $ValLen) {
            my $Chunk = substr($Value, $Pos, $MaxChars);
            $Chunk =~ s/\"/\\\"/g;
            $Pos += $MaxChars;
            my $JSCall = sprintf("selenium.browserbot.findElement(\"%s\").value += \"%s\";", $Locator, $Chunk);
            $self->do_command("getEval", $JSCall);
            sleep 2;
        }
    }
    else {
        $self->do_command("type", $Locator, $Value);
    }
}

Re: 414 Request URI Too Large

Hi,

 

You might want to file a JIRA ticket for this.

Re: 414 Request URI Too Large

I've confirmed this is an issue with the Perl driver (see http://ttwhy.org/home/blog/2008/05/14/selenium-rc-per-session-extension-javascript/). I did not experience the issue using the Java driver.

Re: 414 Request URI Too Large

Hi balrog

 

Could you point me to the Python fix please. I've tried replicating your code in python but I'm having some trouble with it.


def type(self,locator,value):
     """
     Sets the value of an input field, as though you typed it in.


     Can also be used to set the value of combo boxes, check boxes, etc. In these cases,
     value should be the value of the option selected, not the visible text.


     'locator' is an element locator
     'value' is the value to type
     """

     #My mod starts here. Taken from http://clearspace.openqa.org/message/43878
     max_chars = 2000;
     value_length = len(value)
     if value_length > max_chars:
          pos = 0;
          while pos&lt;value_length:
               chunk = value[pos:max_chars]
               chunk = chunk.replace('"', '\\"')
               pos += max_chars;
               js_call = 'selenium.browserbot.findElement("%s").value += "%s";' % (locator, chunk)
               self.do_command("getEval", js_call)
               time.sleep(2)
     else:
          self.do_command("type", [locator,value,])

 

Thanks

 

fintan.

Re: 414 Request URI Too Large

If you're using a fairly recent Selenium RC, you can build the Python driver from trunk, which has the fix. See SRC-321 (http://jira.openqa.org/browse/SRC-321).

Re: 414 Request URI Too Large

Thanks Haw-Bin Chai for the reply. How recent? I've 9.2 for the server and client. Would I need one of the release candidates?

Re: 414 Request URI Too Large

9,2 should be fine for the Selenium server. You will have to build the python driver from trunk, though, as that was a very recent check-in. There are instructions here:

Re: 414 Request URI Too Large

Hi all,

Thanks balrog for your code __, I like ruby and modified your code:

 

def type(locator,value)
          @MaxChars = 2000
          if !value.nil? then
            @ValLen =value.size
          end
          if (@ValLen > @MaxChars) &amp;&amp; (!value.nil?) then
            @Pos = 0;
            @JSCall = sprintf("selenium.browserbot.findElement(\"%s\").value = \"%s\";", locator, nil)
            do_command("getEval", [@JSCall,]) 
            while (@Pos&lt;@ValLen)
              @Chunk=value[@Pos,@MaxChars]
              @Chunk=@Chunk.sub(/\"/,"\\\"")
              @Pos += @MaxChars
              @JSCall = sprintf("selenium.browserbot.findElement(\"%s\").value += \"%s\";", locator, @Chunk)
                do_command("getEval", [@JSCall,])
              sleep 0.1
            end
          else
            do_command("type", [locator,value,])
          end
    end
