401响应推特反向身份验证

Question

这是我使用的授权标头：

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\"";

以下是我使用的基本字符串：

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

以下是我的推特文档：

步骤1：获取特殊请求令牌

首先，您使用应用程序的使用者密钥向Twitter请求令牌URLhttps://api.twitter.com/oauth/request_token发出HTTPS请求。除了传统的oauth_*签名参数之外，您还必须包含设置为reverse_auth值的x_auth_mode。

例如，考虑使用令牌秘密ydC2yUbFaScbSlykO0PmrMjXFeLraSi3Q2HfTOlGxQM签名的具有以下值的请求：

这里使用的代币仅用于演示目的，不适用于您。

oauth\u consumer\u key JP3PyvG67rXRsnayOJOcQ oauth\u nonce 1B7D865D-9E15-4ADD-8165-EF90D7A7D3D2 oauth\u signature\u方法HMAC-SHA1 oauth\u时间戳1322697052 oauth\u版本1.0 x\u auth\u mode reverse\u auth这些参数应生成一个签名基字符串，如下所示：

（为清晰起见，添加了换行）：

OAuthoauth_nonce="xq2maKtilFhVTC1MSxVC4cQIJLd53O6w97YmrdOGSk8"，oauth_signature_method="HMAC-SHA1"，oauth_timestamp="1322697052"，oauth_consumer_key="JP3PyvG67rXRsnayOJOcQ"，oauth_token="5mgkU82W0PTA0DLgSIA5vFK6c08i8dXzrbLnX06vl38"，oauth_signature="aOM/wW2kAowAeHBRvw7faH245p0="，oauth_version="1.0"

编辑：我仍然得到401英镑。我使用了以下代码来生成oauth\u签名，因此现在我的授权标头如下所示：oauth oauth\u timestamp=“1376639141”，oauth\u nonce=“BB2D2634F3-99A5-4B64-8CB34E-2314CE9E4FD7”，oauth\u version=“1.0”，oauth\u consumer\u key=“MRCD8LUSNKJKFACHHYI2YY2QWH5TCFMDAS”，oauth\u签名方法=“HMAC-SHA1”，oauth\u签名=“MOER8H7XZLUAH”DOAAAFZPV6N4NOEU=“

        if(string) {
            additionalBodyParameters = [NSURL ab_parseURLQueryString:string];

    NSMutableDictionary *parameters = [[oAuthAuthorizationParameters mutableCopy] autorelease];

    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],

    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;
}

我传递给此方法的参数是url：https://api.twitter.com/oauth/request_token，方法：POST，正文：nil，oAuthConsumerToken:my key，OAuthConsumerCret:my secret，oAuthToken:nil，oAuthTokenSecret:nil。

编辑我尝试使用这个oauth测试控制台来验证我是否正确生成了oauth签名，但似乎我需要成员的令牌和密码：

您尚未在授权标头中包含oauth\u签名。
