401响应Twitter的反向权威性

Question

这里是授权头使用：

Authorization = "OAuth oauth_consumer_key=\"2D9rLD8Lu23hrchrh4VMBkQ6AZKHYi2yY2oeuoeutcFMdAs\", oauth_nonce=\"-486353546\", oauth_signature="x3NdGnJmBTUAICBRE9C44N8mFd4%3D", oauth_signature_method=\"HMAC-SHA1\", oauth_timestamp=\"137663828056\", oauth_version=\"1.0\", x_auth_mode=\"reverse_auth\""; 

这里的基本字符串我用：

https://api.twitter.com/oauth/access_token 

下面是我从工作twitter documentation：

步骤1：获取特殊请求标记

首先，您使用您的应用程序的 使用者密钥向Twitter请求令牌URL发送HTTPS请求 https://api.twitter.com/oauth/request_token。除了传统的oauth_ *参数 参数外，还必须包含设置为值 reverse_auth的x_auth_mode。

举个例子，考虑下面的值的请求与令牌机密ydC2yUbFaScbSlykO0PmrMjXFeLraSi3Q2HfTOlGxQM签署 ：

这里使用的令牌仅用于演示的目的，并不会为你 工作。

oauth_consumer_key JP3PyvG67rXRsnayOJOcQ oauth_nonce 1B7D865D-9E15-4ADD-8165-EF90D7A7D3D2 oauth_signature_method HMAC-SHA1 oauth_timestamp 1322697052 oauth_version 1.0 x_auth_mode reverse_auth 这些参数应导致的签名基本字符串，看起来 像这样：

POST & HTTPS％3A％2F％2Fapi.twitter.com％2Foauth％2Frequest_token & oauth_consumer_key％3DJP3PyvG67rXRsnayOJOcQ％26oauth_nonce％3D1B7D865D-9E15-4ADD-8165-EF90D7A7D3D2％26oauth_signature_method％3DHMAC-SHA1％26oauth_timestamp％3D1322697052％26oauth_version％3D1.0％26x_auth_mode％ 3Dreverse_auth 这个调用应该导致看起来像这样的响应。注意 这个响应实际上看起来像一个OAuth头。

（换行添加为清楚起见）：

的OAuth oauth_nonce = “xq2maKtilFhVTC1MSxVC4cQIJLd53O6w97YmrdOGSk8”， oauth_signature_method = “HMAC-SHA1”，oauth_timestamp = “1322697052”， oauth_consumer_key = “JP3PyvG67rXRsnayOJOcQ”， 组oauth_token =“5mgkU82W0PTA0DLgSIA5vFK6c08i8dXzrbLnX06vl38 ”， oauth_signature = “AOM％2FwW2kAowAeHBRvw7faH245p0％3D”， oauth_version = “1.0”

编辑：我STIL我得到401。我用下面的代码来生成oauth_signature，所以现在我的Authorization头看起来是这样的：OAuth oauth_timestamp="1376639141", oauth_nonce="BB2D2634F3-99A5-4B64-8CB34E-2314CE9E4FD7", oauth_version="1.0", oauth_consumer_key="mrcD8LuSNKJKFAchKHYi2yY2qwh5tcFMdAs", oauth_signature_method="HMAC-SHA1", oauth_signature="moer8H7xzluAdoAAAFZpv6n4noeu%3D"

NSString *OAuthorizationHeader(NSURL *url, NSString *method, NSData *body, NSString *_oAuthConsumerKey, NSString *_oAuthConsumerSecret, NSString *_oAuthToken, NSString *_oAuthTokenSecret) 
{ 
    NSString *_oAuthNonce = [NSString ab_GUID]; 
    NSString *_oAuthTimestamp = [NSString stringWithFormat:@"%d", (int)[[NSDate date] timeIntervalSince1970]]; 
    NSString *_oAuthSignatureMethod = @"HMAC-SHA1"; 
    NSString *_oAuthVersion = @"1.0"; 

    NSMutableDictionary *oAuthAuthorizationParameters = [NSMutableDictionary dictionary]; 
    oAuthAuthorizationParameters[@"oauth_nonce"] = _oAuthNonce; 
    oAuthAuthorizationParameters[@"oauth_timestamp"] = _oAuthTimestamp; 
    oAuthAuthorizationParameters[@"oauth_signature_method"] = _oAuthSignatureMethod; 
    oAuthAuthorizationParameters[@"oauth_version"] = _oAuthVersion; 
    oAuthAuthorizationParameters[@"oauth_consumer_key"] = _oAuthConsumerKey; 
    if(_oAuthToken) 
     oAuthAuthorizationParameters[@"oauth_token"] = _oAuthToken; 

    // get query and body parameters 
    NSDictionary *additionalQueryParameters = [NSURL ab_parseURLQueryString:[url query]]; 
    NSDictionary *additionalBodyParameters = nil; 
    if(body) { 
     NSString *string = [[[NSString alloc] initWithData:body encoding:NSUTF8StringEncoding] autorelease]; 
     if(string) { 
      additionalBodyParameters = [NSURL ab_parseURLQueryString:string]; 
     } 
    } 

    // combine all parameters 
    NSMutableDictionary *parameters = [[oAuthAuthorizationParameters mutableCopy] autorelease]; 
    if(additionalQueryParameters) [parameters addEntriesFromDictionary:additionalQueryParameters]; 
    if(additionalBodyParameters) [parameters addEntriesFromDictionary:additionalBodyParameters]; 

    // -> UTF-8 -> RFC3986 
    NSMutableDictionary *encodedParameters = [NSMutableDictionary dictionary]; 
    for(NSString *key in parameters) { 
     NSString *value = parameters[key]; 
     encodedParameters[[key ab_RFC3986EncodedString]] = [value ab_RFC3986EncodedString]; 
    } 

    NSArray *sortedKeys = [[encodedParameters allKeys] sortedArrayUsingFunction:SortParameter context:encodedParameters]; 

    NSMutableArray *parameterArray = [NSMutableArray array]; 
    for(NSString *key in sortedKeys) { 
     [parameterArray addObject:[NSString stringWithFormat:@"%@=%@", key, encodedParameters[key]]]; 
    } 
    NSString *normalizedParameterString = [parameterArray componentsJoinedByString:@"&"]; 

    NSString *normalizedURLString = [NSString stringWithFormat:@"%@://%@%@", [url scheme], [url host], [url path]]; 

    NSString *signatureBaseString = [NSString stringWithFormat:@"%@&%@&%@", 
            [method ab_RFC3986EncodedString], 
            [normalizedURLString ab_RFC3986EncodedString], 
            [normalizedParameterString ab_RFC3986EncodedString]]; 

    NSString *key = [NSString stringWithFormat:@"%@&%@", 
        [_oAuthConsumerSecret ab_RFC3986EncodedString], 
        (_oAuthTokenSecret) ? [_oAuthTokenSecret ab_RFC3986EncodedString] : @""]; 

    NSData *signature = HMAC_SHA1(signatureBaseString, key); 
    NSString *base64Signature = [signature base64EncodedString]; 

    NSMutableDictionary *authorizationHeaderDictionary = [[oAuthAuthorizationParameters mutableCopy] autorelease]; 
    authorizationHeaderDictionary[@"oauth_signature"] = base64Signature; 

    NSMutableArray *authorizationHeaderItems = [NSMutableArray array]; 
    for(NSString *key in authorizationHeaderDictionary) { 
     NSString *value = authorizationHeaderDictionary[key]; 
     [authorizationHeaderItems addObject:[NSString stringWithFormat:@"%@=\"%@\"", 
              [key ab_RFC3986EncodedString], 
              [value ab_RFC3986EncodedString]]]; 
    } 

    NSString *authorizationHeaderString = [authorizationHeaderItems componentsJoinedByString:@", "]; 

    authorizationHeaderString = [NSString stringWithFormat:@"OAuth %@", authorizationHeaderString]; 

    return authorizationHeaderString; 
} 

我通过这个方法的参数是 url：https://api.twitter.com/oauth/request_token，method：POST，body：无，oAuthConsumerToken ：我的钥匙，oAuthConsumerSecret：我的秘密，oAuthToken：无，oAuthTokenSecret：无。

编辑我想这oauth test console来验证我正确生成OAuth的签名，但现在看来，我需要会员的令牌和秘密：

您还没有包括oauth_signature在授权标题中。
