ASIHTTPRequest Error messages - Beginner

问题

I am using ASIHttpRequest. I need to know what this error message means ? and how could i resolve it

Request error <ASIHTTPRequest: 0xbedc00> -- Error Domain=ASIHTTPRequestErrorDomain Code=1 "A connection failure occurred" UserInfo=0x270230 {NSUnderlyingError=0x250cf0 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 2.)", NSLocalizedDescription=A connection failure occurred}

There are many more error messages; the above is Error Domain=ASIHTTPRequestErrorDomain Code=1 Other are Code=2, Code=3 ... upto Code=10. I need to what these are too ?

edit: The errors gets displayed inside the if condition

 SBJsonParser *p = [SBJsonParser new];              
       NSDictionary *content = [pobjectWithString:[request responseString]];       
       if(!content){       
           NSLog(@" %@", p.errorTrace);
           return;
       }

This error means that the host cannot be contacted, most often because you don't have a network connection.

Here are the error codes defined in ASIHTTPRequest.h

typedef enum _ASINetworkErrorType {
    ASIConnectionFailureErrorType = 1,
    ASIRequestTimedOutErrorType = 2,
    ASIAuthenticationErrorType = 3,
    ASIRequestCancelledErrorType = 4,
    ASIUnableToCreateRequestErrorType = 5,
    ASIInternalErrorWhileBuildingRequestType  = 6,
    ASIInternalErrorWhileApplyingCredentialsType  = 7,
    ASIFileManagementError = 8,
    ASITooMuchRedirectionErrorType = 9,
    ASIUnhandledExceptionError = 10,
    ASICompressionError = 11

} ASINetworkErrorType;

回答2:

you should try something like this

-(void)requestFailed:(ASIHTTPRequest *)request{ 

       UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[request.error localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
       [alertView show];
}
