Objective-C Requires Chilkat v11.0.0+

HTTP Methods - GET and DELETE

Demonstrate a method for sending HTTP requests that don't have a request body, such as for GET or DELETE requests. Objective-C

#import <CkoHttp.h>
#import <NSString.h>
#import <CkoHttpResponse.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];

//  Specifiy a session log file so we can see the exact request/response
http.SessionLogFilename = @"c:/aaworkarea/sessionLog.txt";

//  Perhaps add a custom header or two..
[http SetRequestHeader: @"x-exz-date" value: @"20201012T235046Z"];
[http SetRequestHeader: @"x-exz-id" value: @"1234"];

//  Send a GET request to https://www.example.com/someting?param1=123&param2=abc
NSString *url = @"https://www.example.com/someting?param1=123&param2=abc";
CkoHttpResponse *resp = [[CkoHttpResponse alloc] init];
success = [http HttpNoBody: @"GET" url: url response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

//  The GET request that is sent looks like this.
//  The Accept and Accept-Encoding headers are automatically added by default.

//  	GET /someting?param1=123&param2=abc HTTP/1.1
//  	Host: www.example.com
//  	Accept: */*
//  	Accept-Encoding: gzip
//  	x-exz-date: 20201012T235046Z
//  	x-exz-id: 1234

//  Get the response status
int statusCode = [resp.StatusCode intValue];
NSLog(@"%@%d",@"Response status: ",statusCode);

//  Get the response body
NSLog(@"%@",resp.BodyStr);

//  -------------------------------------------------------------
//  Let's say we want to send a DELETE request, and we only want to accept an application/json response,
//  and we don't want gzipped responses...

//  First remove the previously specified custom headers.
[http ClearHeaders];

//  Indicate we only accept application/json non-gzipped responses.
http.Accept = @"application/json";
http.AllowGzip = NO;

//  Send a DELETE request to https://www.example.com/deleteSomething
url = @"https://www.example.com/deleteSomething";
success = [http HttpNoBody: @"DELETE" url: url response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

//  The DELETE request that is sent looks like this.
//  The empty Accept-Encoding header value means we only want non-compressed responses.

//  	DELETE /deleteSomething HTTP/1.1
//  	Host: www.example.com
//  	Accept: application/json
//  	Accept-Encoding: 

//  Get the response status
statusCode = [resp.StatusCode intValue];
NSLog(@"%@%d",@"Response status: ",statusCode);

//  Get the response body
NSLog(@"%@",resp.BodyStr);
