当我从 LinkedIn 向 请求请求令牌时https://api.linkedin.com/uas/oauth/requestToken，我收到以下错误：

oauth_problem=signature_invalid&oauth_problem_advice=com.linkedin.security.auth.pub.LoginDeniedInvalidAuthTokenException%20while%20obtaining%20request%20token%20for%20%3APOST%26https%253A%252F%252Fapi.linkedin.com%252Fuas%252Foauthoauth%_callback%252Foauthoauth%252Frequest%6 253Doob％2526oauth_consumer_key％253DI9DvH3zT4c-sjmrQTmo_AeJOfi8v8n1ChYHYAV8A3siVLyu1qLZqPq_HiGecD0bp％2526oauth_nonce％253D2958724240022％2526oauth_signature_method％253DHMAC-SHA1％2526oauth_timestamp％253D1308562221％2526oauth_version％253D1.0％0AOAU％3AI9DvH3zT4c-sjmrQTmo_AeJOfi8v8n1ChYHYAV8A3siVLyu1qLZqPq_HiGecD0bp％7C％2A01％7C％2A01％7C％2A01％3A1308562221％3AkPisU0TwUgiNIYpigUrKITMwo7c％ 3D

这是 HTTP 401 未经授权的响应。

例外：

连接LinkedIn的示例源代码：

package com.neurologic.example;

    }

    public RequestToken requestUnauthorizedRequestToken() throws OAuthException {
        return consumer.requestUnauthorizedToken(LINKEDIN_API_URL, CALLBACK_URL, null, new OAuthHmacSha1Signature());
    }

    public String getAuthorizationUrl(RequestToken token) throws OAuthException {
        return consumer.createOAuthUserAuthorizationUrl(token, null);
    }

    public AccessToken requestAccessToken(AuthorizedToken authorizedToken, RequestToken requestToken) throws OAuthException {
        return consumer.requestAccessToken(LINKEDIN_API_URL, requestToken, authorizedToken, new OAuthHmacSha1Signature());
    }

    /**

     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            LinkedInExample example = new LinkedInExample();
            RequestToken rt = example.requestUnauthorizedRequestToken();

            //Now that we have request token, let's authorize it....
            String url = example.getAuthorizationUrl(rt);

            //Copy the URL to your browser and make sure that OAuth 1 Servlet is running....
        } catch (OAuthException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

我的图书馆：JOAuth（1.2.1 版）。com.linkedin.security.auth.pub.LoginDeniedInvalidAuthTokenException从 LinkedIn返回建议，我做错了什么？

谢谢

PS： OAuth 1 与 Twitter 完美配合（经过测试），因此我不明白发生了什么。此外，LinkedIn 使用 JOAuth 符合的 OAuth 1.0 修订版 A（以及 RFC5849）。

似乎 JOAuth 库没有正确计算签名。我需要查看完整的请求和响应才能进一步调试。您的应用程序名称是什么？

请参阅我对 Absolute minimum code 的回答，以获得在 Java 或 Groovy 中填充的有效 oauth_signature？ 也许它会有所帮助:)

我已经想通了。问题在于标准化基本字符串 URI。URI 的路径不能是小写的（我的路径是小写的）。我已经解决了这个问题。问题出在方法中找到的net.oauth.util.OAuth1Util.normalizeUrl()方法中。
