IOSLinkedInAPI：无法与LinkedIn API共享帖子 [英] IOSLinkedInAPI: Can't share post with the LinkedIn API
问题描述
我一直在使用以下SDK来将LinkedIn集成到iOS并从iDevices分享帖子。
I have been using following SDK to perform integration of LinkedIn into iOS and sharing post from iDevices.
SDK可在此处获取： https://github.com/jeyben/IOSLinkedInAPI
SDK is available here: https://github.com/jeyben/IOSLinkedInAPI
在这段代码中，我找不到合适的示例代码，但是我编写了一些可以共享帖子的代码。这是我的代码：
In this code I can't find proper example code but however I had written some code through which post can be shared. Here is my code:
在代码中我只有一个viewcontroller，其中我只有两个按钮，1）Linked In Account [此按钮用于显示登录控制器并让用户成功登录帐户] 2）分享[允许用户代表登录用户在请求失败的情况下共享内容]
In the code I have only single viewcontroller in which I have taken only two buttons, 1) Linked In Account [This button is used to present login controller and gets user successfully logged into the account] 2) Share [Allows user to share content on behalf of logged in user where the request fails]
ViewController.h
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

#import "ViewController.h"
@interface ViewController ()

@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);
}];
}
要使此应用程序正常运行，请从上面的SDK下载内容并添加所有必需的内容文件进入项目。
To make this app work, download content from the above SDK and add every required file into the project.
当我尝试登录应用程序时，我收到了成功的消息，但在此之后，当我尝试按照上面的代码分享任何帖子时，我得到了失败并看看什么是控制台：
When I try to login the app, I get successful message but after that when I try to share any post as described in above code, I get failure and see what is console:
Printing description of error:

} }}
我尝试过很多关于AFNetworking，LinkedIn授权，未经授权的访问等等，但在此没有找到任何东西。如果你们中的任何人都知道这件事或者建议我使用LinkedIn iPhone SDK的任何其他选项，请告诉我。
I have tried searching a lot on AFNetworking, LinkedIn authorization, Unauthorized access, etc. but could not found anything over this. Let me know if anyone of you are aware of something about this or suggest me any other option for LinkedIn iPhone SDK.
推荐答案
你需要将请求序列化程序更改为 AFJSONRequestSerializer 并在驼峰大小写中替换字典上的键。这是我的分享帖子代码：
You need to change the request serializer to AFJSONRequestSerializer and replace the keys on the dictionary in camel case. This is my code for share post:
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);
}];
重要提示：根据Linkedin的说法，字典的键是骆驼案例API。
Important: the keys of the dictionary are in camel case according to Linkedin API.
