Question

I am using OAuth-Sample-Client code to send invitation from email address via Linked Invitation API.
I have created the same body as described in developer site,but right now I am getting error of 401,I have searched a lot of on it but didn’t get any solution which get me out of it from any site or forum.
My response is as below.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<error>
  <status>401</status>
  <timestamp>1351159386437</timestamp>
  <request-id>YX4NRU3S7J</request-id>
  <error-code>0</error-code>
  <message>[unauthorized]. OAU:ron8e8nko3te|e0a96317-dfdc-44fb-b427-5655e02f97ed|*01|*01:1351159294:dRCDN6b3K9F/mwWAaByKZQPgeVw=</message>
</error>

Here my json string would be like this:

{“body”:”Say yes!”,”subject”:”Invitation to
connect.”,”recipients”:{“values”:[{“person”:{“first-name”:”test”,”last-name”:”test”,”_path”:”/people/email=[e-mail]”}}]},”item-content”:{“invitation-request”:{“connect-type”:”friend”}}}

I have used the code as below to send Invitation.

- (IBAction)postButton_TouchUp:(UIButton *)sender
{    
    [statusTextView resignFirstResponder];
    NSURL *url = [NSURL URLWithString:@"http://api.linkedin.com/v1/people/~/mailbox"];
    OAMutableURLRequest *request = 
    [[OAMutableURLRequest alloc] initWithURL:url
                                    consumer:oAuthLoginView.consumer
                                       token:oAuthLoginView.accessToken
                                    callback:nil
                           signatureProvider:[[OAHMAC_SHA1SignatureProvider alloc] init]];


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

    NSDictionary *temp=[[NSDictionary alloc]initWithObjectsAndKeys:@"/people/email=[e-mail]",@"_path",@"test",@"first-name",@"test",@"last-name", nil];
    NSDictionary *temp2=[[NSDictionary alloc] initWithObjectsAndKeys:temp,@"person",nil];
    NSArray *arr2=[[NSArray alloc]initWithObjects:temp2, nil];
    NSDictionary *value=[[NSDictionary alloc]initWithObjectsAndKeys:arr2,@"values", nil];
    NSDictionary *dict3=[[NSDictionary alloc]initWithObjectsAndKeys:@"friend",@"connect-type",nil];
    NSDictionary *dict4=[[NSDictionary alloc] initWithObjectsAndKeys:dict3,@"invitation-request", nil];
    NSDictionary *dict=[[NSDictionary alloc]initWithObjectsAndKeys:dict4,@"item-content",@"Say yes!",@"body",@"Invitation to connect.",@"subject",value,@"recipients", nil];
    NSLog(@"%@",[dict description]);
    NSString *updateString = [dict JSONString];
    [request setHTTPBodyWithString:updateString];
    [request setHTTPMethod:@"POST"];

    OADataFetcher *fetcher = [[OADataFetcher alloc] init];
    [fetcher fetchDataWithRequest:request
                         delegate:self
                didFinishSelector:@selector(postUpdateApiCallResult:didFinish:)
                  didFailSelector:@selector(postUpdateApiCallResult:didFail:)];    
    [request release];
}

I got stuck at this point,Please get me out of this.
-Thanks in advance

Answer 1

call prepare method of OADataFetcher manually. Just put it before setting the body of the request.

[request prepare];
[request setHTTPBodyWithString:updateString];

This is working for me.
Also remove the prepare method from the OADataFetcher when you are working with Invitation API.
