如何使用RESTFul Web服务发送请求？

Question

I have sucessfully received value from http://rest-service.guides.spring.io/greeting by using RESTFul and json web services. But unable to send my own text box value in request to my own server running apache on another machine.

my working code -:

- (IBAction)fetchGreeting;
{
    NSURL *url = [NSURL URLWithString:@"http://rest-service.guides.spring.io/greeting"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [NSURLConnection sendAsynchronousRequest:request
                                       queue:[NSOperationQueue mainQueue]
                           completionHandler:^(NSURLResponse *response,
                                               NSData *data, NSError *connectionError)
     {
         if (data.length > 0 && connectionError == nil)
         {
             NSDictionary *greeting = [NSJSONSerialization JSONObjectWithData:data
                                                                      options:0
                                                                        error:NULL];
             self.greetingId.text = [[greeting objectForKey:@"id"] stringValue];
             self.greetingContent.text = [greeting objectForKey:@"content"];
         }
     }];
}

But it stop working when i change NSURL *url = [NSURL URLWithString:@" http://rest-service.guides.spring.io/greeting "]; value to my own server address, and also unable to wrap my own text box value in request.

Answer 1

We usually add our textfield data into the request like this.

NSString *url =[NSString stringWithFormat:@" http://rest-service.guides.spring.io/greeting/%@ ",textFied.text];

Can you show how your URL look like?
