Examine HTTP Response Status Code and Text

See more REST Examples

Demonstrates how to examine the HTTP response status code and text when using the REST object. Objective-C

#import <CkoRest.h>
#import <NSString.h>

BOOL success = NO;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

CkoRest *rest = [[CkoRest alloc] init];

//  We're going to check https://authenticationtest.com/HTTPAuth/
BOOL bTls = YES;
int port = 443;
BOOL bAutoReconnect = YES;
success = [rest Connect: @"authenticationtest.com" port: [NSNumber numberWithInt: port] tls: bTls autoReconnect: bAutoReconnect];
if (success != YES) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

//  Send a GET request
NSString *responseText = [rest FullRequestNoBody: @"GET" uriPath: @"/HTTPAuth/"];
if (rest.LastMethodSuccess != YES) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

//  The start line of an HTTP response, called the status line, contains the following information:
//  
//      The protocol version, usually HTTP/1.1.
//      A status code, indicating success or failure of the request. Common status codes are 200, 404, or 302
//      A status text. A brief, purely informational, textual description of the status code to help a human understand the HTTP message.
//  
//  A typical status line looks like: HTTP/1.1 404 Not Found.

//  The ResponseStatusCode property contains the integer response code:
NSLog(@"%@%d",@"Response status code = ",[rest.ResponseStatusCode intValue]);

//  The ResponseStatusText property contains the text (if any) that follows the status code on the status line.
NSLog(@"%@%@",@"Response status text = ",rest.ResponseStatusText);

//  In this case, the sample output is:
//  
//  Response status code = 401
//  Response status text = Unauthorized
