Can't share using OAuth Starter Kit for LinkedIn

问题

I use OAuthStarter Kit for accessing the LinkedIn API. I get an access token successfully for the permissions.

rw_ns
r_basicprofile
r_fullprofile

It is possible to get the profile details as well as to share only comments and while sharing URL or image or description etc... I using following code:

-(void)postUpdate
 {
   NSURL *url = [NSURL URLWithString:@"http://api.linkedin.com/v1/people/~/shares"];
   OAMutableURLRequest *request =
   [[OAMutableURLRequest alloc] initWithURL:url
                            consumer:[self getConsumer]
                               token:self.accesstoken
                            callback:nil
                   signatureProvider:nil];

   NSDictionary *update = [[NSDictionary alloc] initWithObjectsAndKeys:

                    [[NSDictionary alloc]
                     initWithObjectsAndKeys:
                     @"anyone",@"code",nil], @"visibility",
                    @"title goes here",@"title",
                    @"comment goes here", @"comment",
                    @"description goes here",@"description",
                     @"www.google.com",@"submitted-url",
                    @"http://economy.blog.ocregister.com/files/2009/01/linkedin-logo.jpg",@"submitted-image-url",
                    nil];
   [request setValue:@"json" forHTTPHeaderField:@"x-li-format"];
   [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

   NSString *updateString = [update 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:)];

  }

But I get a response error as follows:

 2012-10-09 18:27:29.906 SocialConnectTest[9460:19a03] data {
 "errorCode": 0,
 "message": "Invalid xml {Expected elements 'post-network-update@http://api.linkedin.com/v1 id@http://api.linkedin.com/v1 visibility@http://api.linkedin.com/v1 comment@http://api.linkedin.com/v1 attribution@http://api.linkedin.com/v1 content@http://api.linkedin.com/v1 private-message@http://api.linkedin.com/v1 share-target-reach@http://api.linkedin.com/v1' instead of 'submitted-url@http://api.linkedin.com/v1' here in element share@http://api.linkedin.com/v1}",
 "requestId": "W2G7WJDHOJ",
 "status": 400,
 "timestamp": 1349787449685
}

And I don't know what the problem is. Can anyone please help me solving this?

回答1:

i fixed it. The problems is in the post parameters

As per the documentation of Linked in api,if we use JSON in request body then keys of post params must be in camel case, while in xml "-" seperated key names are used.
Share parameter like submittedUrl , subsubmittedImageUrl , description,title **etc. must be values of key called **content.

so i modified the code as follows..

-(void)postUpdateHERE
{
  NSURL *url = [NSURL URLWithString:@"http://api.linkedin.com/v1/people/~/shares"];
  OAMutableURLRequest *request =
  [[OAMutableURLRequest alloc] initWithURL:url
                            consumer:[self getConsumer]
                               token:self.accesstoken
                            callback:nil
                   signatureProvider:nil];

  NSDictionary *update = [[NSDictionary alloc] initWithObjectsAndKeys:

                    [[NSDictionary alloc]
                     initWithObjectsAndKeys:
                     @"anyone",@"code",nil], @"visibility",

                    @"comment goes here", @"comment",
                    [[NSDictionary alloc]
                     initWithObjectsAndKeys:
                    @"description goes here",@"description",
                    @"www.google.com",@"submittedUrl",
                      @"title goes here",@"title",
                    @"http://economy.blog.ocregister.com/files/2009/01/linkedin-logo.jpg",@"submittedImageUrl",nil],@"content",
                    nil];
  [request setValue:@"json" forHTTPHeaderField:@"x-li-format"];
  [request setValue:@"application/xml" forHTTPHeaderField:@"Content-Type"];
  NSString *updateString = [update 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:)];

}

now the code works for me..
