我正在尝试获取 Linkedin 公司更新到我的网站。按照流程https://developer.linkedin.com/documents/authentication并通过注册生成 api 密钥和密钥。

根据文档，我能够在步骤 a 中生成授权码。对于步骤 b 生成访问令牌，我在 java 中使用 OAuth。

request = OAuthClientRequest.tokenLocation("https://www.linkedin.com/uas/oauth2/accessToken")
                        .setGrantType(GrantType.AUTHORIZATION_CODE)
                        .setCode("****")
                        .setRedirectURI("https://www.example.in")
                        .setClientId("*******")
                        .setClientSecret("******").buildBodyMessage();
                    OAuthClient oAuthClient = new OAuthClient(new URLConnectionClient());
                    GitHubTokenResponse oAuthResponse = oAuthClient.accessToken(request, GitHubTokenResponse.class);
                    String accessToken = oAuthResponse.getAccessToken();
                    String expiresIn = oAuthResponse.getExpiresIn();

但是出现错误

OAuthProblemException{description='Missing parameters: access_token', error='invalid_request', uri='null', state='null', scope='null'}

我发现了这个问题。

Looks like there is a problem in the documentation. Apologies.

Right call is

request = OAuthClientRequest.tokenLocation("https://www.linkedin.com/uas/oauth2/accessToken")
                    .setGrantType(ResponseType.CODE.toString())
                    .setCode("****")
                    .setRedirectURI("https://www.example.in")
                    .setClientId("*******")
                    .setClientSecret("******").buildBodyMessage();

Mind ResponseType.CODE.toString() rather than GrantType.AUTHORIZATION_CODE

我建议您在此处阅读一些linkedin 开发人员文档，并查看 java OAuth 库，而不是手动执行签名过程。然后你可以问一个具体的问题。
