javascript - LinkedIn oauth 错误缺少必需的参数 "client_id"

Question

所以我刚刚从 LinkedIn oauth 1.0 升级到 2.0，我已经收到这个错误大约一天了。我在 php 上看到了一篇关于它的帖子，但我无法在 Node JS (Javascript) 中弄清楚这是我当前的代码:

axios
    .post("https://www.linkedin.com/oauth/v2/accessToken", {
      grant_type: "authorization_code",
      code: req.query.code,
      redirect_uri: keys.linkedinCallbackURL,
      client_id: keys.linkedinConsumerKey,
      client_secret: keys.linkedinConsumerSecret
    })
    .then(res2 => {
      console.log(res2);
    })
    .catch(error => {
      console.log(error);
    });

如果您有任何想法，请告诉我:)

Answer 1

LinkedIn 文档要求您将数据作为 application/x-www-form-urlencoded 发送，他们向我们展示了这个示例:

POST /oauth/v2/accessToken HTTP/1.1
Host: www.linkedin.com
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&code=987654321&redirect_uri=https%3A%2F%2Fwww.myapp.com%2Fauth%2Flinkedin&client_id=123456789&client_secret=shhdonottell

Axios documentation 表示默认情况下主体被序列化为 JSON:

By default, axios serializes JavaScript objects to JSON.

为了正确序列化正文，您应该使用 querystring 模块，如下所示:

const querystring = require('querystring');

axios
    .post("https://www.linkedin.com/oauth/v2/accessToken", querystring.stringify({
      grant_type: "authorization_code",
      code: req.query.code,
      redirect_uri: keys.linkedinCallbackURL,
      client_id: keys.linkedinConsumerKey,
      client_secret: keys.linkedinConsumerSecret
    }));
