LinkedIn邀请API错误401 [未经授权] -iPhone sdk

Question

我正在使用OAuth-Sample-Client代码通过Linked Invitation API从电子邮件地址发送邀请。 我创建了与开发人员网站中描述的相同的主体，但是现在我收到401的错误，我已经搜索了很多内容，但没有得到任何解决方案，让我从任何网站或论坛中取出它。 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>

在这里，我的json字符串将是这样的：

{“body”：“Say yes！”，“subject”：“邀请连接。”，“收件人”：{“值”：[{“person”：{“first-name”：“test”，“last” -name “：” 测试 “ ”_路径“： ”/ people/email=test@test.com“}}]}， ”项内容“：{ ”邀请请求“：{ ”连接型“：”朋友“}}}

我使用下面的代码发送邀请。

- (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];
}

我在这一点上陷入困​​境，请让我离开这个。 -提前致谢

Answer 1

手动调用OADataFetcher的准备方法。 只需在设置请求正文之前将其放入。

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

这对我有用。 当您使用Invitation API时，也从OADataFetcher中删除prepare方法。

Answer 2

Apple的代码有效！ 还有一件事，不要忘记任何标题。 我仍然收到相同的消息，结果我忘了添加x-li-format和Content-type标头。

我从这个Linkedin线程得到了解决方案

您只需要在代码中进行一些更改：

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];

并在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];
        
}
        

试试这个。 肯定会工作的。 希望这将有助于未来的访客。
