如何发布到LinkedIn“分享"与节点身份验证?

这就是我所拥有的，但是LinkedIn返回了未经授权"的错误:

This is what I have, but LinkedIn returns "unauthorized" error back:

var OAuth= require('oauth').OAuth;

oa= new OAuth("https://api.linkedin.com/uas/oauth/requestToken",
    "https://api.linkedin.com/uas/oauth/accessToken",
    "key",  "secret", "1.0A", "http://test.com/oauth/callback", "HMAC-SHA1");

var post_data = {
share: {
   "comment":"testing 123",
   "visibility": {
    "code":"anyone"
   }
}
};

oa.post("http://api.linkedin.com/v1/people/~/shares?twitter-post=true", oauth_token, oauth_token_secret, post_data, 'application/json; charset=UTF-8', function(error, data){
 }

感谢任何帮助.当获取资源时，oauth_token和oauth_token_secret可以工作，所以我认为它们是正确的.

Appreciate any help. The oauth_token and oauth_token_secret works when fetching resources, so I think they are correct.

此致
