Question

我正在尝试创建一个连接到OAUth 1的Web服务的应用程序，我遇到了一些麻烦。这是我的获取请求的方法：

- (void)loadUserProfile
{
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[baseUrl]];
    NSMutableURLRequest *request = [httpClient requestWithMethod:@"GET"
                                                        path:[NSString  stringWithFormat:@"/1/user/%@/profile.json", [SSKeychain passwordForService:@"[service]" account:@"encoded_user_id"]]
                                                  parameters:nil];

    NSString *postString = [NSString  stringWithFormat:@"oauth_consumer_key=%@&oauth_token=%@&oauth_nonce=%@&oauth_signature_method=%@&oauth_timestamp=%@&oauth_version=%@", self.auth.consumerKey, [SSKeychain  passwordForService:@"[service]" account:@"oauth_token"], self.auth.nonce,  self.auth.signatureMethod, self.auth.timestamp, self.auth.version];
    [request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        // Print the response body in text
        NSLog(@"Response: %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
    [operation start];
}

当我调用此方法时，我收到以下错误：

Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."  UserInfo=0x8efa7f0  {NSErrorFailingURLStringKey=https://api.fitbit.com/1/user/[id]/profile.json,  NSErrorFailingURLKey=https://api.fitbit.com/1/user/[id]/profile.json,  NSLocalizedDescription=The network connection was lost., NSUnderlyingError=0x8bdb2c0 "The  network connection was lost."}

我想要获得的资源在此处记录：https://wiki.fitbit.com/display/API/OAuth+Authentication+in+the+Fitbit+API#OAuthAuthenticationintheFitbitAPI-tokenCredentials。

之前我没有使用过OAuth 1，我之前从未见过这个错误，所以我不知道如何解决它。有什么想法吗？

Answer 1

我使用Simple Oauth1解决了这个问题。像这样：

NSString *path = [NSString stringWithFormat:@"/1/user/%@/profile.json", [SSKeychain    passwordForService:@"Fitbit" account:@"fitbit_encoded_user_id"]];
NSURLRequest *preparedRequest = [OAuth1Controller preparedRequestForPath:path
                                                              parameters:nil
                                                              HTTPmethod:@"GET"
                                                              oauthToken:[SSKeychain passwordForService:@"Fitbit" account:@"fitbit_oauth_token"]
                                                             oauthSecret:[SSKeychain passwordForService:@"Fitbit" account:@"fitbit_oauth_token_secret"]];

AFJSONRequestOperation *operation = [AFJSONRequestOperation   JSONRequestOperationWithRequest:preparedRequest success:^(NSURLRequest *request,   NSHTTPURLResponse *response, id jsonObject) {
    NSLog(@"JSON: %@", jsonObject);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON, NSError *error) {
    NSLog(@"Error: %@", error);
}];

[operation start];

Answer 2

问题在于AFHTTPClient在方法-loadUserProfile结束时内存不足。

您需要重构此代码，以便在请求后客户端仍保留在内存中。

一种方法是使用AFNetworking中示例代码中所示的单例模式。

Answer 3

就我而言，解决方案是重启Xcode和模拟器。

该网址在桌面浏览器中使用curl。意识到这有点暗示环境可能有问题。

FWIW，Xcode版本为6.0 beta，版本为6A279r。

AFNetworking获取请求，获取NSURLErrorDomain Code = -1005
