Getting back HTTP error 406 when trying to post data.

[Keisi]

I am trying to set up RKClient post request for the following cURL statement

curl -i -H "Content-Type: application/json" -H "Accept: application/json" -d '{"username":"username","password":"password"}' url_goes_here

which returns the expected json.

However, when I set up RestKit as follows i get an HTTP 406 error code, I cannot understand what is happening.

Note: url_goes_here is equivalent to the final url after RKClient merges it with the base_url.

[[RKClient sharedClient] setValue:@"application/json" forHTTPHeaderField:@"Accept"];

[[RKClient sharedClient] setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

NSDictionary* params = [NSDictionary dictionaryWithObjectsAndKeys:@"admin",@"username",@"password",@"password", nil];

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

The error I am getting is as follows

Any help would be appreciated

Isn't curl -d posting that information into the body of the message? You are telling Restkit to send the information via params:params.

Yes it does, I tried to update my code to the following but I am
getting the same response.

RKRequest *request = [RKRequest requestWithURL:URL delegate:self];
request.queue = [RKClient sharedClient].requestQueue;
request.method = RKRequestMethodPOST;
request.HTTPBodyString = @"{\"username\":\"username\",\"password\":
\"password\"}";
request.additionalHTTPHeaders = [NSDictionary
dictionaryWithObjectsAndKeys:@"application/
json",@"Accept",@"application/json",@"Content-type",@"42",@"Content-
length", nil];
[request send];

As a note, I tried to use NSURLConnections and the same thing was
happening????

Now I am pretty lost.

[Jonathan Hoskin]

I think I've made this recommendation before on this list, but here goes again. It would be a really good idea to use a debugging HTTP proxy to see what is actually being sent and recieved over the wire.

I use one every day and I don't know how anyone can develop a web-connected app without it.

The one I use is Charles: http://charlesproxy.com

If you are using the iOS simulator, you don't need to do anything to make it go through Charles, it just works.

Wow,

Jonathan thank you so much!!! That was incredibly useful. In
retrospect though it showed me a fatal mistake, when I tried to login
using while running Charles I got the response

***************
Response Code | 406 Not Acceptable: Already logged in as admin
***************

So, I cleared the simulator restarted and it was golden! Now, I am
just confused as to why the server was allowing me to "log in"
multiple times through cURL but not through the simulator.

As a side but-related question. Do you know how to print these
description of the error message

For example "Already logged in as admin" or "Missing required argument
username" which I did manage to get through cURL. statusCode just
returns 406 and localizedStatusCode just returned unacceptable.

Thanks for the advise to pick up Charles.

It sounds like the server is creating a session cookie in the app on the simulator after you log in; I would imagine if you wiped the simulator again it would allow you to log in again.

In one of my apps, I do this to delete all local cookies, when I want to make sure my app is "logged out" of my server:

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
for (NSHTTPCookie *cookie in cookies) {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
}

RestKit may also have some magic method for doing this.

I assume you are getting called back with this method:

- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error

In which case, you should be able to inspect objectloader.response.body to see that error message.
