Add a Path Substitution Parameter to a REST Request

See more REST Examples

Demonstrates Rest.AddPathParam, which adds or replaces a path-substitution parameter. Before a request is sent, each occurrence of the name in the URI path is replaced with its value.

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

BOOL success = NO;

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

//  Connect to the REST server.  The 3rd argument enables TLS (use true for HTTPS on port 443),
//  and the 4th enables automatic reconnection if the connection is dropped between requests.
BOOL bTls = YES;
BOOL bAutoReconnect = YES;
success = [rest Connect: @"example.com" port: [NSNumber numberWithInt: 443] tls: bTls autoReconnect: bAutoReconnect];
if (success == NO) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

//  Add path-substitution parameters.  Before a request is sent, each occurrence of the name in the
//  URI path is replaced with the value.  This keeps the path template readable.
[rest AddPathParam: @"{userId}" value: @"12345"];
[rest AddPathParam: @"{orderId}" value: @"98765"];

//  The placeholders in the path are replaced before the request is sent.
NSString *responseText = [rest FullRequestNoBody: @"GET" uriPath: @"/users/{userId}/orders/{orderId}"];
if (rest.LastMethodSuccess == NO) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

NSLog(@"%@",responseText);
