ios - Withings API - 访问 protected 资源

Question

我正在编写一个提取 Withings 数据的 iOS 应用程序，并使用来自 simple-oauth1 的代码(我之前成功地使用它与 Fitbit API 对话)。成功获取到request token，进行认证，然后获取到access token。然后我继续通过向 http://wbsapi.withings.net/once?action=probe 发送 oauthenticated GET 请求来确保为访问 protected 资源设置了基础我得到一个错误代码 0(一切似乎都在工作......)但是，当我尝试对 http://wbsapi.withings.net 进行任何其他调用时，我遇到了错误 250(“提供的用户 ID 和/或 Oauth 凭证不匹配”)。

代码如下:

- (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);
                           });
                       }];
}

请求的格式如下(OAuth1Controller.m 中的 Christian 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;
}

我确定我有正确的用户 ID(此处编辑为“1234567”)但我不确定为什么我不能用它来提取数据。我有一种感觉，这就是代码被破坏的地方。请帮忙。

在此代码部分中，在创建“queryString”时发送“allParameters”而不是“queryParameters”。此外，在创建 queryString 之前，如果之前已添加，请从 allParameters 中删除@“OAuth-callback”键及其对象。检查此链接，希望它会起作用。 http://integratingwithings.blogspot.in/2014/05/withings-api-declassified-ios.html
