Question

我有一个应用程序，其中包含有关在LinkedIn上注册的一些公司的信息。工人罚款超过6个月，但几天前它开始崩溃。原因是现在LinkedIn API并不认为它通过请求“https://api.linkedin.com/uas/oauth/requestToken”提供的访问令牌是有效的。我正在使用 Spring.Social.LinkedIn 库来获取有关公司的信息。那么，这就是我在代码中所做的：的授权：

      OAuthLinkedIn _oauth = new OAuthLinkedIn();
      string _linkedInUserToken = _oauth.GetRequestToken();
      string _linkedInUserSecret = _oauth.TokenSecret;
      var provider = new LinkedInServiceProvider(_linkedInApiKey, _linkedInApiSecret); -> here I set keys provided for my application by LinkedIn
      ILinkedIn _api = provider.GetApi(_linkedInUserToken, _linkedInUserSecret);

然后我想了解一些公司的信息：

Task<string> task = _api.ProfileOperations.GetCompanyByNameAsync(companyName);
string resJson = task.Result;

在最后一行我得到例外，说我没有被授权。以下是访问令牌的请求：

POST https://api.linkedin.com/uas/oauth/requestToken HTTP/1.1
User-Agent: YourAgent
Content-Type: application/x-www-form-urlencoded
Host: api.linkedin.com
Content-Length: 221
Connection: Keep-Alive

oauth_callback=liconnect%3A%2F%2Fsuccess&oauth_consumer_key=**%MY_KEY%**&oauth_nonce=4201230&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1411263546&oauth_version=1.0&oauth_signature=P8GrtPq54XFdiu6HNFaWbQAND%2bc%3d

回复是：

HTTP/1.1 200 OK

Content-Type: text/plain
Content-Length: 240

oauth_token=77--99160ec7-e43f-49ea-916c-c040a882e32b&oauth_token_secret=62e5d39c-8f2a-4908-8114-eb255af3a01b&oauth_callback_confirmed=true&xoauth_request

所以看起来很好。然后我试图获取有关公司的信息。请求是：

GET https://api.linkedin.com/v1/companies/universal-name=valtech:(id,name,employee-count-range,num-followers,locations)?format=json HTTP/1.1
Accept: text/plain,*/*
Authorization: OAuth oauth_consumer_key="**%MY_KEY%**", oauth_signature_method="HMAC-SHA1",     oauth_timestamp="1411263578", oauth_nonce="1543633253", oauth_version="1.0", oauth_token="77--99160ec7-e43f-49ea-916c-c040a882e32b", oauth_signature="bX1A1Fu%2BRvT%2BvtDzgMwrWIqIGM4%3D"
Host: api.linkedin.com

响应是：

}

它困惑了我:(这段代码工作了很长时间，但现在它失败了:(我试图找到一些关于此类错误的类似帖子，但我不能。有任何想法如何解决这个问题？谢谢
