如何解决使用JOAuth库在LinkedIn中发布作业
| 这是我在Java上的LinkedIn Job Posting API实现上发布的问题的延续。我是发布作业的基于OAuth的身份验证的新手，并且在此过程中也正在学习。如果我的问题非常基础/天真，请与我一起接受。 我正在尝试使用JOAuth库进行OAuth身份验证并将作业发布到LinkedIn。我正在使用OAuth2调用。我对JOAuth库有以下疑问： 在JOAuth链接显示的示例中，如何获取LinkedIn的请求令牌？我找不到任何请求请求令牌的声明。但我看到consumer.generateRequestAuthorizationUrl(ResponseType.CODE,redirectUri,null,(String[])null));
redirectUri
解决方法
你很困惑。 LinkedIn使用OAuth 1协议，而不是OAuth 2协议。这是您对LinkedIn进行Oauth 1授权的方法。
如果要创建Web应用程序，请在
WEB-INF
oauth-config.xml
<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<oauth-config>
<!-- LinkedIn OAuth Config -->
<oauth name=\"linkedIn\" version=\"1\">
<consumer key=\"API_KEY\" secret=\"API_SECRET\" />
<provider requestTokenUrl=\"https://api.linkedin.com/uas/oauth/requestToken\" authorizationUrl=\"https://api.linkedin.com/uas/oauth/authorize\" accessTokenUrl=\"https://api.linkedin.com/uas/oauth/accessToken\" />
</oauth>
<service path=\"/authorize_ready\" class=\"com.neurologic.example.LinkedInOAuthService\" oauth=\"linkedIn\">
<success path=\"/start.htm\" />
</service>
</oauth-config>
