Send post request in XML format using RestKit

Hi I am using restkit for first time, and there are several questions that come to my mind. First when sending a post request using restkit what format is the request Json or XML and how can I specify it? I am sending a post request to the server to authenticate a user and should receive a conformation if details correct in XML format.

NSArray *objects = [NSArray arrayWithObjects: email, password, nil];
NSArray *keys = [NSArray arrayWithObjects:@"username", @"password", nil];
NSDictionary *params = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

[[RKClient sharedClient] post:@"/login" params:params delegate:self];

This is the code I am using, the xml accepted by the web services should look like

<login>
  <username>[email protected]</username>
  <password>Password</password>
</login>

It is sending the request,but I am not getting the right response. Is there a way to view what is the format of the request I am sending to the server ?

You can use RKRequestSerialization class to do the xml serialization for you.

Here is a code snippet from one of my projects:

#import <RestKit/RKRequestSerialization.h>

...

[RKObjectManager sharedManager].acceptMIMEType = RKMIMETypeTextXML;

NSString *loginData = @"<Login><UserId>test</UserId><Password>test</Password></Login>";

[[RKClient sharedClient] setValue:@"XYZ01" forHTTPHeaderField:@"ServiceId"]; 
[[RKClient sharedClient] post:@"/login" 
                       params:[RKRequestSerialization serializationWithData:[loginDetails dataUsingEncoding:NSUTF8StringEncoding] MIMEType:RKMIMETypeTextXML] 
                     delegate:self];

And, here is the dump using RKLogConfigureByName("RestKit/Network", RKLogLevelTrace)

2012-08-12 11:28:41.476 MyApp[730:707] T restkit.network:RKRequest.m:402 Prepared POST URLRequest '<NSMutableURLRequest https://someserver.com/MyApp/rest/service/request>'. HTTP Headers: {
    Accept = "text/xml";
    "Content-Length" = 75;
    "Content-Type" = "text/xml";
    ServiceId = XYZ01;
}. HTTP Body: <Login><UserId>test</UserId><Password>test</Password></Login>

I solved this using ASIHTTPRequest and XMLWriter. Unfortunate, but RestKit just doesn't seem to support XML posts out the box.

I do use RK for GETting stuff though.

I did objectManager.serializationMIMEType = RKMIMETypeXML; but the Content-Length of my request is 0, and the HTTP Body is empty. If I use RKMIMETypeJSON the request looks fine, but the xml serialization doesn't work. Any ideas why this happens? What else do I need to do to post xml with valid serialization?

I also found this in doc: "RestKit currently supports serialization to RKMIMETypeFormURLEncoded and RKMIMETypeJSON". So, how can I use RKObjectManager to post xml?

Give this a try. I think it is supposed to do what you want. I never got it to work but I had other things wrong with my code.

    RKObjectManager* objectManager = [RKObjectManager objectManagerWithBaseURL:@"http://mysite.com"];

    objectManager.serializationMIMEType = RKMIMETypeXML;

Note: this may be what you do for sending XML back to you, not sending XML to the server. Don't know off the top of my head.

Sounds like you are using the wrong call. The post call you are using assumes that the rest service wants params like login=username&password=skdjgh, i.e. NOT in XML, but in 'normal REST format'. You need to either find a call to post a block of text using RestKit, or use another call. In other words you need to create the XML yourself (or use some library) then send that via a post.
