Withings -访问受保护的资源

Question

我正在编写一个iOS应用程序来获取Withing数据，并使用simple-oauth1中的代码(我之前使用它成功地与Fitbit API进行了对话)。我成功地获得了一个请求令牌，对其进行了身份验证，然后获得了一个访问令牌。然后，我向http://wbsapi.withings.net/once?action=probe发送了一个经过oauthenticated的GET请求，以确保为访问受保护的资源设置了基础工作。我得到了一个错误代码0(一切似乎都正常工作……)但是，当我尝试调用http://wbsapi.withings.net时，遇到错误250 (“提供的用户I和/或Oauth凭证不匹配”)。

下面是代码的样子：

- (void)getUserInfo
{
    NSString *path = @"measure";
    NSMutableDictionary *moreParams = [[NSMutableDictionary alloc] init];
    [moreParams setValue:@"getmeas" forKey:@"action"];
    [moreParams setValue:@"1234567" forKey:@"userid"];

    NSURLRequest *preparedRequest = [OAuth1Controller preparedRequestForPath:path
                                                              parameters:moreParams
                                                              HTTPmethod:@"GET"
                                                              oauthToken:self.oauthToken
                                                                   oauthSecret:self.oauthTokenSecret];

[NSURLConnection sendAsynchronousRequest:preparedRequest
                                   queue:NSOperationQueue.mainQueue
                       completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
                           dispatch_async(dispatch_get_main_queue(), ^{

                               if (error) NSLog(@"Error in API request: %@", error.localizedDescription);
                           });
                       }];
}

下面是请求的格式(Christian在OAuth1Controller.m中的代码)：

+ (NSURLRequest *)preparedRequestForPath:(NSString *)path
                          parameters:(NSDictionary *)queryParameters
                          HTTPmethod:(NSString *)HTTPmethod
                          oauthToken:(NSString *)oauth_token
                         oauthSecret:(NSString *)oauth_token_secret
{
    if (!HTTPmethod
    || !oauth_token) return nil;

NSMutableDictionary *allParameters = [self standardOauthParameters].mutableCopy;

allParameters[@"oauth_token"] = oauth_token;

if (queryParameters) {
    [allParameters addEntriesFromDictionary:queryParameters];
}

NSString *parametersString = CHQueryStringFromParametersWithEncoding(allParameters, NSUTF8StringEncoding);

NSString *request_url = API_URL;
if (path) request_url = [request_url stringByAppendingString:path];
NSString *oauth_consumer_secret = CONSUMER_SECRET;
NSString *baseString = [HTTPmethod stringByAppendingFormat:@"&%@&%@", request_url.utf8AndURLEncode, parametersString.utf8AndURLEncode];
NSString *secretString = [oauth_consumer_secret.utf8AndURLEncode stringByAppendingFormat:@"&%@", oauth_token_secret.utf8AndURLEncode];

NSString *oauth_signature = [self.class signClearText:baseString withSecret:secretString];

allParameters[@"oauth_signature"] = oauth_signature;
allParameters[@"oauth_signature_method"] = @"HMAC-SHA1";

NSString *queryString;

if (queryParameters) {
    queryString = CHQueryStringFromParametersWithEncoding(queryParameters, NSUTF8StringEncoding);
}
if (queryString) {
    request_url = [request_url stringByAppendingFormat:@"?%@", queryString];
}

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:request_url]];
request.HTTPMethod = HTTPmethod;

NSMutableArray *parameterPairs = [NSMutableArray array];
[allParameters removeObjectsForKeys:queryParameters.allKeys];

for (NSString *name in allParameters) {
    NSString *aPair = [name stringByAppendingFormat:@"=\"%@\"", [allParameters[name] utf8AndURLEncode]];
    [parameterPairs addObject:aPair];
}

NSString *oAuthHeader = [@"OAuth " stringByAppendingFormat:@"%@", [parameterPairs componentsJoinedByString:@","]];
[request setValue:oAuthHeader forHTTPHeaderField:@"Authorization"];

return request;
}

我确信我有正确的用户it (这里编辑为"1234567")，但是我不确定为什么我不能使用它来拉取数据。我有种感觉，这就是代码崩溃的地方。请帮帮忙。

在这段代码中发送" allParameters“而不是"queryParameters”，在创建“queryString”回调时再创建回调，删除@“OAuth-.Also”键并从allParameters中删除它的对象，如果添加了previously.check这个链接，希望它能工作。http://integratingwithings.blogspot.in/2014/05/withings-api-declassified-ios.html
