HTTPKit

HTTPKit is a lightweight framework for building webservers in Objective-C or Tranquil.

Build steps

• git clone --recursive https://github.com/fjolnir/HTTPKit.git
• Edit the SDKVERSION in dependencies/iphone-openssl/build-libssl.sh to match your current Xcode's SDK version.
• execute build-libssl.sh
• Open Xcode project and hit build.

Basic usage

#import <HTTPKit.h>

int main(int argc, const char * argv[])
{
    @autoreleasepool {
        HTTP *http = [HTTP new];
        // Simple "Hello you!" pong
        [http handleGET:@"/hello/*"
                   with:^(HTTPConnection *connection, NSString *name) {
            return [NSString stringWithFormat:@"Hello %@!", name];
        }];
        
        // Simplified login example
        [http handleGET:@"/login"
                   with:^(HTTPConnection *connection) {
                       return @"<form method=\"post\" action=\"/login\">"
                              @"<label for=\"username\">Name:</label>"
                              @"<input name=\"username\" type=\"text\">"
                              @"<label for=\"password\">Password:</label>"
                              @"<input name=\"password\" type=\"password\">"
                              @"<input type=\"submit\" value=\"Sign in\">"
                              @"</form>";
                   }];
        [http handlePOST:@"/login" with:^(HTTPConnection *connection) {
            NSLog(@"logging in user: %@ with password: %@",
                  [connection requestBodyVar:@"username"],
                  [connection requestBodyVar:@"password"]);
            return @"Welcome! I trust you so I didn't even check your password.";
        }];
        [http listenOnPort:8081 onError:^(id reason) {
            fprintf(stderr, "Error starting server: %s", [reason UTF8String]);
            exit(1);
        }];
        [[NSRunLoop mainRunLoop] runUntilDate:[NSDate distantFuture]];
    }
    return 0;
}

Or written in tranquil as:

import "HTTPKit"
import "html"
t = Tag
HTTP new handleGET: "/hello/*" with: `conn, name| "Hello «name»!"`;
         handleGET: "/login" with: { conn |
             t html: "Log in" :[
                 t :#form :[
                     t :#label :"Name:" :{ #for  => #username },
                     t :#input :nil     :{ #name => #username, #type => #text },
                     t :#label :"Password:" :{ #for  => #password },
                     t :#input :nil         :{ #name => #password, #type => #password },
                     t :#input :nil :{ #value => "Sign in", #type => #submit  }
                 ] :{ #method => #post }
             ]
         };
        handlePOST: "/login" with: { conn |
             "Logging in user: «conn requestBodyVar: #username» with password: «conn requestBodyVar: #password»" print
             ^"Welcome! I trust you so I didn't even check your password."
        };
        listenOnPort: 8080 onError: { reason | "Error starting server: «reason»" print. ^^1 }
