exception when parsing an array in JSON

lucaazori · May 2011

hi all, when i try to parse an array returned from my web-service i got this exception :

 2011-05-03 23:28:10.021  -JSONValue failed. Error trace is: (
        \"Error Domain=org.brautaset.JSON.ErrorDomain Code=11 \\"Unexpected end of string\\" UserInfo=0x803d8b0 {NSLocalizedDescription=Unexpected end of string}\"
    )

here is my code :

 -(void)requestFinished:(ASIHTTPRequest *)request{
    	
    	
    	if(request.responseStatusCode==200)
    	{
    	   //parse the response
    		NSArray *array=[[request responseString]JSONValue];
    		listeTypesDesCarburants=[array objectAtIndex:0];
    		listeDesEnseignes=[array objectAtIndex:1];
    		
    	}
    }

listeTypesDesCarburants

and

listeDesEnseignes

are both a `NSArray`

That error means the JSON you are parsing is badly formatted. You'll have to fix the server you are downloading from.

NSLog(@\"%@\",[request responseString]);

hi ,actually i have already make another JSON request that communicate with the same server, so the server is fine, however i googled somewhere and i found that may be the problem is that, for this JSON request, i'm not passing any parameter, i only receive response, also it may be that, in the URL i specify the file where the web-service is like that :

http://myServer.com/admin_V01/stationsProcessing/pickers_management.php

because the other web-service for the JSON request above was in index.php so the url was :

http://myServer.com.com/admin_V01/stationsProcessing/

should it be in an index file ? am i obliged to send parameters with the request? otherwise help please 'cause my issue still unresolved, thx in advance :)

i'm starting to think that you don't understand the problem and what are you trying to do. :rolleyes:

again......post the response

NSLog(@\"%@\",[request responseString]);

[CODE]if(request.responseStatusCode==200)
{

i don't see NSLog of string Response

NSLog(@"My String Response is: %@",[request responseString]);

However is clear that is not a JSON string.....and basically this is the problem.

ok, so it is a empty. and you can understand that you can't parse a empty string as JSON, right?
