iPhone 與 RoR 對話

這篇主要是利用POST把iPhone上的東西傳給RoR Server
iPhone的寫法就是這樣
- (void)viewDidLoad {
    [super viewDidLoad];
    NSURL *url = [NSURL URLWithString:@"http://127.0.0.1/getTest"];
    NSString* content = @"first=michael&second=pan";
   
    NSMutableURLRequest* urlRequest = [[NSMutableURLRequest alloc]initWithURL:url];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setHTTPBody:[content dataUsingEncoding:NSASCIIStringEncoding]];
    NSURLConnection * myConnection = [[[NSURLConnection alloc] initWithRequest:urlRequest delegate:self] autorelease];
}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
    NSLog(@"response %@", response.URL );
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    NSLog(@"received data %@", [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease ]);
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
    NSLog(@"error occurs");
}

在RoR端
直接用

在Controller的部分改成這樣
=====================
class EchoTestController < ApplicationController
    skip_before_filter :verify_authenticity_token
    def index
          render :text => 'Hello ' + params["first"]
    end
end
=====================
這樣就可以了
在iPhone端會收到
