Tumblr Xauth Android - 400错误请求错误

时间：2012-01-24 22:02:43

标签： android tumblr xauth

我正在尝试与Tumblr一起使用Xuath。我已经通过电子邮件向Tumblr支持团队发送电子邮件，以便为我的应用启用Xuath，他们有义务。但是，在尝试检索用户密钥和密钥时，我不断收到“400：错误请求”错误。我找不到调试错误请求的方法。

以下是代码:( 注意 - 此代码是从网络上提供的代码段开发的）

    return signature;
}

我知道在这里找出确切的错误是非常困难的。但是，如果有人能提出建议或指出我正确的方向，我会很高兴。

String headerValue 具有以下值：

的OAuth oauth_nonce = “8d0e6e03ae2424260ddd647d5afba70d”，oauth_signature_method = “HMAC-SHA1”，oauth_timestamp = “1327434351943”，oauth_consumer_key = “mdMFLrprZGnRw4XO736GXcXP8huxaxTT5z1nlxDK38GbyWlW38”，oauth_signature = “cYNStrfA％2F2lTaGKL8pxWHpzSq9w％3D”，oauth_version = “1.0”

所以，它似乎是正确的格式。将换行符添加到字符串中会有帮助吗？

在将我的头发分开几天之后，事实证明我在HTTP帖子中发送了太多信息（因此，错误的请求错误被抛回了我）。所有必要的是以下一组参数：

x_auth_username（用户的电子邮件地址），x_auth_password和x_auth_mode = client_auth

另外，我应该使用强大的Oauth Library函数，而不是尝试使用我有限的知识编写自己的函数。在我的辩护中，文档从来都不是很清楚。非常好的一课 - 关于重新编写代码和使用常识。对于那些可能想知道TUMBLR是否存在合法的Java客户端的人 - 这里是github链接：https://github.com/nsheridan/tumblr-java。我向你们保证，这是我遇到过的最好的Tumblr代码。

经过大量搜索后，在Twitter上找到了以下代码 - 

            // replace with your username and password
            String password = “passwd”;
            String userName = “test@test.com”;

                    new BasicNameValuePair("x_auth_mode", "client_auth"));

            AuthToken authToken = null;
            try {
                UrlEncodedFormEntity entity = new UrlEncodedFormEntity(reqParams, HTTP.UTF_8);
                httppost.setEntity(entity);

                    in.close();
                    String responseString = out.toString(); 

                    String[] splitResponse = StringUtils.split(responseString, "&");
                    String accessTokenSecret = getParameter(splitResponse, "oauth_token_secret");
                    String accessToken = getParameter(splitResponse, "oauth_token");

                }
