LinkedIn邀請API錯誤401 [未經授權] -iPhone sdk

Question

我正在使用OAuth-Sample-Client代碼通過Linked Invitation API從電子郵件地址發送邀請。 我創建了與開發人員網站中描述的相同的主體，但是現在我收到401的錯誤，我已經搜索了很多內容，但沒有得到任何解決方案，讓我從任何網站或論壇中取出它。 我的回答如下。

<?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>

在這里，我的json字符串將是這樣的：

{“body”：“Say yes！”，“subject”：“邀請連接。”，“收件人”：{“值”：[{“person”：{“first-name”：“test”，“last” -name “：” 測試 “ ”_路徑“： ”/ people/email=test@test.com“}}]}， ”項內容“：{ ”邀請請求“：{ ”連接型“：”朋友“}}}

我使用下面的代碼發送邀請。

- (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=test@test.com",@"_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];
}

我在這一點上陷入困​​境，請讓我離開這個。 -提前致謝

Answer 1

手動調用OADataFetcher的准備方法。 只需在設置請求正文之前將其放入。

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

這對我有用。 當您使用Invitation API時，也從OADataFetcher中刪除prepare方法。

Answer 2

Apple的代碼有效！ 還有一件事，不要忘記任何標題。 我仍然收到相同的消息，結果我忘了添加x-li-format和Content-type標頭。

Answer 3

我從這個Linkedin線程得到了解決方案

您只需要在代碼中進行一些更改：

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:nil];
    [request setHTTPMethod:@"POST"];
    NSString *messageToPerson = @"/people/email=target@gmail.com";
    NSDictionary *person = [[NSDictionary alloc] initWithObjectsAndKeys:[[[NSDictionary alloc] initWithObjectsAndKeys:messageToPerson,@"_path",@"TargetFirstName",@"first-name",@"TargetSecondName",@"last-name",nil] autorelease], @"person",nil]; 
    NSArray *valueArray = [[NSArray alloc] initWithObjects:person,nil];
    NSDictionary *values = [[NSDictionary alloc] initWithObjectsAndKeys:valueArray,@"values", nil];
    NSDictionary *ir = [[NSDictionary alloc] initWithObjectsAndKeys:[[[NSDictionary alloc] initWithObjectsAndKeys:@"friend",@"connect-type",nil] autorelease], @"invitation-request",nil];
    NSDictionary *ic = [[NSDictionary alloc] initWithObjectsAndKeys:ir,@"item-content", nil];
    NSDictionary *update = [[NSDictionary alloc] initWithObjectsAndKeys:values,@"recipients",@"Invitation",@"subject",@"ConnectWithMe",@"body", ir, @"item-content", nil];
    [request setValue:@"json" forHTTPHeaderField:@"x-li-format"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    NSLog(@"%@",[update description]);
    NSString *updateString = [update JSONString];

    [request prepare];

    [request setHTTPBodyWithString:updateString];

    OADataFetcher *fetcher = [[OADataFetcher alloc] init];
    [fetcher fetchDataWithRequest:request delegate:self
            didFinishSelector:@selector(postUpdateApiCallResult:didFinish:)
            didFailSelector:@selector(postUpdateApiCallResult:didFail:) withId:1];

    [request release];

並在oAdata OADataFetcher.m

- (void)fetchDataWithRequest:(OAMutableURLRequest *)aRequest delegate:(id)aDelegate didFinishSelector:(SEL)finishSelector didFailSelector:(SEL)failSelector  withId:(int)idtm
        {

        [request release];
        
request = [aRequest retain];

        delegate = aDelegate;
        
didFinishSelector = finishSelector;

        didFailSelector = failSelector;

//note this change

        if (idtm!=1) {
   
        [request prepare];
        
       }

connection = [[NSURLConnection alloc] initWithRequest:aRequest delegate:self];
        
}
        

試試這個。 肯定會工作的。 希望這將有助於未來的訪客。
