实施“行人分享给” 401错误

Question

在核心中，我想通过他们的共享选项在用户的LinkedIn个人资料上发布/共享。但是我遇到两个错误：

  

jquery-3.4.1.min.js：2选项https://api.linkedin.com/v2/ugcPosts 401

和

  

从原点“ https://api.linkedin.com/v2/ugcPosts”到“ http://localhost:8080”处对XMLHttpRequest的访问已被CORS策略阻止：对预检请求的响应未通过访问控制检查：否'Access-Control-Allow-来源的标头出现在请求的资源上。

使用的代码是...（作为ajax调用）

function linkedInPost() {
  $.ajax({
    url: 'https://api.linkedin.com/v2/ugcPosts',
    type: 'POST',
    headers: 'X-Restli-Protocol-Version: 2.0.0',
    /*beforeSend:{
        'headers':'X-Restli-Protocol-Version: 2.0.0',
        'Content-Type':'application/json'
    },*/
    data: {
      "author": "urn:li:person:8675309",
      "lifecycleState": "PUBLISHED",
      "specificContent": {
        "com.linkedin.ugc.ShareContent": {
          "shareCommentary": {
            "text": "Learning more about LinkedIn by reading the LinkedIn Blog!"
          },
          "shareMediaCategory": "ARTICLE",
          "media": [{
            "status": "READY",
            "description": {
              "text": "Official LinkedIn Blog - Your source for insights and information about LinkedIn."
            },
            "originalUrl": "https://blog.linkedin.com/",
            "title": {
              "text": "Official LinkedIn Blog"
            }
          }]
        }
      },
      "visibility": {
        "com.linkedin.ugc.MemberNetworkVisibility": "CONNECTIONS"
      }
    },
    success: function(data) {
      console.log("success: ", data);
    },
    error: function(data) {
      console.log("error: ", data)
    }
  })
}

有人可以帮我吗？
