如何使用Apple IOS for iPad设置Basecamp凭据

Question

我正在尝试向我们公司的Basecamp信息申请我们正在建设的内部项目.我理解如何在ASP.NET环境中添加凭据,但我是iPad开发的新手,似乎无法从Basecamp获得适当的响应.这是我正在做的事情:

NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://mybasecampname.basecamphq.com/projects.xml"]
                                             cachePolicy:NSURLRequestUseProtocolCachePolicy
                                          timeoutInterval:60.0 ];

我正在添加Bsaecamp所需的HTTP标头,如下所示:

[theRequest setValue:@"application/xml" forHTTPHeaderField:@"Content-Type" ];
    [theRequest setValue:@"application/xml" forHTTPHeaderField:@"Accept" ];

我知道我还需要发送我的凭据用于身份验证 - 我的身份验证令牌和我喜欢的任何密码,但我不确定最好的方法.这是我正在尝试的:

NSURLCredential *credential = [NSURLCredential credentialWithUser:@"MY TOKEN HERE"
                                                             password:@"x"
                                                persistence:NSURLCredentialPersistenceForSession];

我的问题是:我在这里是正确的轨道还是我完全错过了什么？

这是Basecamp API详细信息的链接,它解释了它需要什么:http://developer.37signals.com/basecamp/

Answer 1

一如既往,我最终解决了这个问题.一旦我开始使用didReceiveAuthenticationChallenge方法,事情开始落实到位.

所以.我简化了我的请求方法:

- (void)startRequest
{
    NSURL *url = [NSURL URLWithString:@"http://mybasecampproject.basecamphq.com/projects.xml"];
    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];

    // Start the connection request
    urlConnection = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];

    }

然后设置接收身份验证质询的方法:

- (void)connection:(NSURLConnection *)connection 
didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    NSLog(@"Authentication challenge..."); 

    NSURLCredential *cred = [[[NSURLCredential alloc] initWithUser:@"my basecamp token here" password:@"X"
                                                           persistence:NSURLCredentialPersistenceForSession] autorelease];
        [[challenge sender] useCredential:cred forAuthenticationChallenge:challenge];

}

然后设置didReceiveData方法来捕获返回的数据:

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    NSLog(@"Did receive data"); 

    NSString * strResult = [[NSString alloc] initWithData: data encoding:NSUTF8StringEncoding];
    NSLog(strResult);
}

希望这有助于其他人.

仍然乐于听到更好的方法
