Objective-C Requires Chilkat v11.0.0+

Example: Http.HttpParams method

Demonstrates the HttpParams method. Objective-C

#import <CkoHttp.h>
#import <CkoJsonObject.h>
#import <NSString.h>
#import <CkoHttpResponse.h>
#import <CkoFileAccess.h>

BOOL success = NO;

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

CkoHttp *http = [[CkoHttp alloc] init];

//  Demonstrate sending a GET request with query parameters.
CkoJsonObject *queryParams = [[CkoJsonObject alloc] init];
[queryParams UpdateInt: @"limit" value: [NSNumber numberWithInt: 100]];
[queryParams UpdateString: @"email" value: @"joe@example.com"];
[queryParams UpdateString: @"token" value: @"VGhlIHF1aWNrIGJyb3duIGZveCBqdW1wZWQgb3ZlciB0aGUgbGF6eSBkb2cuLi4="];

//  Set a session log filename so we can examine the exact request that is sent.
NSString *sessionLogPath = @"c:/temp/qa_output/sessionLog.txt";
http.SessionLogFilename = sessionLogPath;

//  Send the GET request to an endpoint.  We don't care about the response. The purpose of this example
//  is to see the exact HTTP request that is sent..
CkoHttpResponse *resp = [[CkoHttpResponse alloc] init];
success = [http HttpParams: @"GET" url: @"https://chilkatsoft.com/echo_request_body.asp" json: queryParams response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

CkoFileAccess *fac = [[CkoFileAccess alloc] init];
NSString *sessionLog = [fac ReadEntireTextFile: sessionLogPath charset: @"utf-8"];
NSLog(@"%@",sessionLog);
success = [fac FileDelete: sessionLogPath];

//  This is the exact GET request that was sent.
//  Notice how each query parameter is URL encoded and added to the HTTP start line of the request.

//  GET /echo_request_body.asp?limit=100&email=joe%40example.com&token=VGhlIHF1aWNrIGJyb3duIGZveCBqdW1wZWQgb3ZlciB0aGUgbGF6eSBkb2cuLi4%3D HTTP/1.1
