OAuth 2.0 - IOS API V 2.0

Hi, Could you please give some instruction how to get acessToken v2 from accessToken v1?

i know this API "https://api.dropboxapi.com/1/oauth2/token_from_oauth1 but dont know how to pass the parameters. 

i'm using ios sdk

Hi SGS E. none parameters is required, post 

"https://api.dropboxapi.com/1/oauth2/token_from_oauth1" method "POST" with 

Authorization OAuth 1.0 and return access_token OAuth 2.0

very easy.

bye

That's correct, that endpoint requires OAuth 1 signing. This blog post, specifically step 4, may be helpful:

Hi,

I'm sorry but i still cant do it.

Now what i have is DBSession restClien or something like that.Is there anyway to get accesssToken v2 from resclient ?

Could you please give some sample code in your project ?

here is my code but it doesnt work well

 

MPOAuthCredentialConcreteStore* credential = [[DBSession sharedSession] credentialStoreForUserId:[info userId]];

    AFHTTPSessionManager* manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:BASE_URL]];

    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    manager.requestSerializer = [AFHTTPRequestSerializer serializer];

    [manager.requestSerializer setValue:@"OAuth" forHTTPHeaderField:@"Authorization"];

    [manager.requestSerializer setValue:@"1.0" forHTTPHeaderField:@"oauth_version"];

    [manager.requestSerializer setValue:@"PLAINTEXT" forHTTPHeaderField:@"oauth_signature_method"];

    [manager.requestSerializer setValue:APP_KEY_DB forHTTPHeaderField:@"oauth_consumer_key"];

    [manager.requestSerializer setValue:credential.accessToken forHTTPHeaderField:@"oauth_token"];

    [manager.requestSerializer setValue:[NSString stringWithFormat:@"%@&%@",credential.requestTokenSecret,credential.accessTokenSecret] forHTTPHeaderField:@"oauth_signature"];

   [manager POST:@"https://api.dropboxapi.com/1/oauth2/token_from_oauth1" parameters:@{} success:^(NSURLSessionDataTask *task, id responseObject) {

   } failure:^(NSURLSessionDataTask *task, NSError *error) {

   }];

 

//It show error

Code=-1011 "Request failed: bad request (400)"

I don't believe we have any sample code for this specifically in Objective-C unfortunately.

Looking at your code, it seems you are setting all of the OAuth parameters as individual parameters, when they should just be together in the one "Authorization" header, as shown in the blog post I linked to.

yah, you are right , after change the OAuth parameters as the one it works like a charm !

Thank you very much.

btw,dropbox sdk is great but the ios' sdk and its document is quite out of date :(
