IOSLinkedInAPI：無法與LinkedIn API共享文章

Question

我一直在使用以下SDK來執行LinkedIn到iOS的集成以及從iDevices共享文章。

SDK可以在這裏找到：https://github.com/jeyben/IOSLinkedInAPI

在這段代碼中，我找不到合適的示例代碼，但是，但是我已經寫了一些代碼，通過它後可以共享。這裏是我的代碼：

在代碼中，我只有一個viewcontroller，其中我只有兩個按鈕，1）Linked In Account [此按鈕用於呈現登錄控制器並獲取用戶成功登錄到帳戶] 2 ）共享[允許用戶在請求失敗共享代表登錄的用戶內容]

ViewController.h

#import <UIKit/UIKit.h> 
#import "LIALinkedInApplication.h" 
#import "LIALinkedInHttpClient.h" 

@interface ViewController : UIViewController 

@property (nonatomic, strong) LIALinkedInHttpClient *client; 

- (IBAction) linkedInClicked:(id)sender; 
- (void)requestMeWithToken:(NSString *)accessToken; 

@end 

ViewController.m

#import "ViewController.h" 

@interface ViewController() 

@end 

@implementation ViewController 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 

    LIALinkedInApplication *application = [LIALinkedInApplication applicationWithRedirectURL:@"http://www.google.com" clientId:@"w57zqiw6cv73" clientSecret:@"Pj5MVxtkpbefau1v" state:@"something" grantedAccess:@[@"r_fullprofile", @"r_network", @"rw_nus"]]; 
    self.client = [LIALinkedInHttpClient clientForApplication:application presentingViewController:nil]; 

} 

- (IBAction) linkedInClicked:(id)sender { // Login into the account 
    [self.client getAuthorizationCode:^(NSString *code) { 
     [self.client getAccessToken:code success:^(NSDictionary *accessTokenData) { 
      NSString *accessToken = [accessTokenData objectForKey:@"access_token"]; 
      [self requestMeWithToken:accessToken]; 
     }     failure:^(NSError *error) { 
      NSLog(@"Quering accessToken failed %@", error); 
     }]; 
    }      cancel:^{ 
     NSLog(@"Authorization was cancelled by user"); 
    }      failure:^(NSError *error) { 
     NSLog(@"Authorization failed %@", error); 
    }]; 
} 

- (IBAction) postMessage :(id)sender { // Post via logged in account, so, first go login and then share content 
    NSString *strURL = @"https://api.linkedin.com/v1/people/~/shares"; 

    NSMutableDictionary *contents=[[NSMutableDictionary alloc] init]; 
    [contents setValue:@"description goes here" forKey:@"description"]; 
    [contents setValue:@"www.google.com" forKey:@"submitted-url"]; 
    [contents setValue:@"title goes here" forKey:@"title"]; 

    NSMutableDictionary *visible=[[NSMutableDictionary alloc] init]; 
    [visible setValue:@"anyone" forKey:@"code"]; 

    NSMutableDictionary *updatedic=[[NSMutableDictionary alloc] init]; 

    [updatedic setObject:visible forKey:@"visibility"]; 
    [updatedic setObject:contents forKey:@"content"]; 
    [updatedic setValue:@"Check out the LinkedIn Share API!" forKey:@"comment"]; 
    //[updatedic setValue:@"json" forKey: @"x-li-format"]; 

    [self.client POST:strURL parameters:updatedic success:^(AFHTTPRequestOperation *operation, NSDictionary *dict) { 
     NSLog(@"Successfully posted", nil); 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     NSLog(@"Failed post", nil); 
    }]; 
} 

- (void)requestMeWithToken:(NSString *)accessToken { 
    [self.client GET:[NSString stringWithFormat:@"https://api.linkedin.com/v1/people/~?oauth2_access_token=%@&format=json", accessToken] parameters:nil success:^(AFHTTPRequestOperation *operation, NSDictionary *result) { 
     NSLog(@"current user %@", result); 
    }  failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     NSLog(@"failed to fetch current user %@", error); 
    }]; 
} 

爲了使這個應用程序的工作，從上面的SDK下載內容和每一個需要的文件添加到項目中。

當我嘗試登錄該應用程序，我得到成功的消息，但在那之後，當我嘗試共享任何職務，如上面的代碼中所描述的，我得到的失敗，看看什麼是控制檯：

Printing description of error:

    "x-li-format" = xml; 
    "x-li-request-id" = 30K08X3IL7; 
} }} 

我有嘗試了很多關於AFNetworking，LinkedIn授權，未經授權的訪問等，但找不到任何東西。讓我知道如果你們中的任何人都知道這件事，或者建議我爲LinkedIn iPhone SDK提供其他選項。

使用這個庫共享在LinkedIn上，這是很容易。

您需要將請求序列化程序更改爲AFJSONRequestSerializer並以駱駝大小寫替換字典上的鍵。這是我的份額郵編：

NSString *stringRequest = @"https://api.linkedin.com/v1/people/~/shares?oauth2_access_token=ACCESS_TOKEN&format=json"; 

//Request parameter on a dictionary (keys in camel case) 
NSDictionary *update = [[NSDictionary alloc] initWithObjectsAndKeys: 

        [[NSDictionary alloc] initWithObjectsAndKeys: @"anyone",@"code",nil], @"visibility", 
        @"comment to share", @"comment", 
        [[NSDictionary alloc] initWithObjectsAndKeys:@"description share", @"description", 
                   @"link_url", @"submittedUrl", 
                   @"title share",@"title", 
                   @"image_url",@"submittedImageUrl",nil], 
        @"content",nil]; 

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
AFJSONRequestSerializer *requestSerializer = [AFJSONRequestSerializer serializer]; 
[requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
[requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
manager.requestSerializer = requestSerializer; 

[manager POST:stringRequest parameters:update success:^(AFHTTPRequestOperation *operation, id  responseObject) { 
NSLog(@"result: %@", responseObject); 
completionBlock(YES, responseObject, nil); 

} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 

    DDLogError([error localizedDescription]); 
    completionBlock(NO, nil, error); 
}]; 

重要：字典的鍵是駱駝情況下根據LinkedIn的API。

首先，通過IOSLinkdinAPI登錄時存儲訪問令牌。例如

。如果我有單獨的類數據對象，並具有屬性名稱「accessTokesForLinkedIn」，那麼在這個方法的變化將是

- (IBAction) linkedInClicked:(id)sender { // Login into the account 
    [self.client getAuthorizationCode:^(NSString *code) { 
     [self.client getAccessToken:code success:^(NSDictionary *accessTokenData) { 
      NSString *accessToken = [accessTokenData objectForKey:@"access_token"]; 
      [[DataObjects sharedDataObjects] setAccessTokenForLinkedIn:accessToken]; 
      [self requestMeWithToken:accessToken]; 
     }     failure:^(NSError *error) { 
      NSLog(@"Quering accessToken failed %@", error); 
     }]; 
    }      cancel:^{ 
     NSLog(@"Authorization was cancelled by user"); 
    }      failure:^(NSError *error) { 
     NSLog(@"Authorization failed %@", error); 
    }]; 
} 

，現在當我們有機會分享任何文本或網址則該方法是： -

-(void)sharetoLinkedIn:(NSString *)title desc:(NSString *)description path:(NSString *)submitted_url imagePath:(NSString *)submitted_image_url postString:(NSString *)comment 
{ 
    NSString *stringRequest = [NSString stringWithFormat:@"https://api.linkedin.com/v1/people/~/shares?oauth2_access_token=%@&format=json",[[DataObjects sharedDataObjects] accessTokenForLinkedIn]] ; 

    NSDictionary *param = @{ 
          @"content":@{ 
            @"title":title, 
            @"description":description, 
            @"submitted-url":submitted_url, 
            @"submitted-image-url":submitted_image_url 
            }, 
          @"comment": comment, 
          @"visibility": @{ 
            @"code": @"anyone" 
            } 
          }; 


    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:stringRequest]]; 
    [request setHTTPBody:[NSJSONSerialization dataWithJSONObject:param options:0 error:nil]]; 
    [request setHTTPMethod:@"POST"]; 
    [request setAllHTTPHeaderFields:@{@"Content-Type":@"application/json", 
             @"x-li-format":@"json" 

             }]; 

    AFHTTPRequestOperation *op = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSLog(@"result: %@", responseObject); 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     if ([operation.responseString class] == [NSDictionary class]) { 
       //[Utility showAlert:@"LinkedIn" mess:[(NSDictionary *)operation.responseString objectForKey:@"message"]]; 

      NSLog(@"error: %@", [(NSDictionary *)operation.responseString objectForKey:@"message"]); 
     } 
     NSLog(@"error: %@", error); 
    }]; 

    [[NSOperationQueue mainQueue] addOperation:op]; 
}
