(Objective-C) HTTP POST JSON (application/json)Demonstrates how to send a JSON POST using the application/json content-type. Note: This example requires Chilkat v11.0.0 or greater.
#import <CkoHttpRequest.h> #import <CkoHttp.h> #import <NSString.h> #import <CkoHttpResponse.h> BOOL success = NO; // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkoHttpRequest *req = [[CkoHttpRequest alloc] init]; CkoHttp *http = [[CkoHttp alloc] init]; // If any custom headers need to be included with the POST, add them // by calling SetRequestHeader // Note: An application should never explicitly set the Content-Length header. // The Content-Length is automatically computed and added by Chilkat. // Here are some examples of custom headers. // Perhaps your particular app needs some sort of custom-computed Authorization header... [http SetRequestHeader: @"Authorization" value: @"my-custom-computed-auth-value"]; // Another custom header for some hypothetical app: [http SetRequestHeader: @"X-Pass-Timestamp" value: @"my-custom-computed-timestamp-value"]; // The following "Accept" header may be set, but it really isn't necessary: [http SetRequestHeader: @"Accept" value: @"application/json"]; NSString *jsonText = @"{ some JSON text ... }"; // To use SSL/TLS, simply use "https://" in the URL. CkoHttpResponse *resp = [[CkoHttpResponse alloc] init]; success = [http HttpStr: @"POST" url: @"http://www.someserver.com/someJsonEndpoint" bodyStr: jsonText charset: @"utf-8" contentType: @"application/json" response: resp]; if (success == NO) { NSLog(@"%@",http.LastErrorText); return; } // Display the JSON response. NSLog(@"%@",resp.BodyStr); |
