我正在編寫一個iOS應用程序,它可以提取Withings數據並使用simple-oauth1中的代碼(我以前曾成功地使用過與Fitbit API交談的代碼)。我成功獲取了一個請求令牌,對其進行了身份驗證,然後獲得了一個訪問令牌。然後,我繼續確保通過向http://wbsapi.withings.net/once?action=probe發送經過驗證的GET請求來設置訪問受保護資源的基礎。我得到了一個錯誤代碼0(一切似乎都在正常工作......) 但是,當我嘗試進行任何其他調用http://wbsapi.withings.net,我遇到了錯誤250(「提供的用戶標識和/或Oauth憑證不匹配」)。Withings API - 訪問受保護的資源
下面是代碼的樣子:
- (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);
});
}];
}
這是怎樣的請求被格式化(在OAuth1Controller.m基督徒的代碼):
+ (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;
}
我敢肯定,我有正確的用戶標識符(在這裏編輯爲「1234567」),但我不確定爲什麼我不能用它來提取數據。我有一種感覺,這就是代碼打破的地方。請幫忙。
任何機會,你可以發佈你使用simple-oauth1成功驗證Withings的代碼嗎?我可以讓登錄頁面出現,但是當我嘗試輸入我的憑據時,它只是重新加載登錄頁面,而不是將我帶到授權頁面。 – bmueller
