【问题描述】：

我尝试使用节点 js 对印象笔记用户进行身份验证，一切正常，直到调用回调 url，然后我收到状态码 400 的错误

我的代码：

app.get('/api/auth/authenticate', function(req, res){

    var client = new Evernote.Client({
        consumerKey: evernoteConfig.EVERNOTE_CONSUMER_KEY,
        consumerSecret: evernoteConfig.EVERNOTE_CONSUMER_SECRET,
        sandbox: true 
    });

    client.getRequestToken(evernoteConfig.callbackURL, function(error, 
        oauthToken, oauthTokenSecret, results){

         if(error) {
      req.session.error = JSON.stringify(error);
      res.json("Shit:"+req.session.error);
    }
    else { 
      // store the tokens in the session
      req.session.oauthToken = oauthToken;
      req.session.oauthTokenSecret = oauthTokenSecret;

      // redirect the user to authorize the token
      res.redirect(client.getAuthorizeUrl(oauthToken));
    }
    });

});

 app.get('/api/auth/evernote/callback', function(req, res){
    var client = new Evernote.Client({
  consumerKey: evernoteConfig.API_CONSUMER_KEY,
  consumerSecret: evernoteConfig.API_CONSUMER_SECRET,
  sandbox: true
});

client.getAccessToken(
  req.session.oauthToken, 
  req.session.oauthTokenSecret, 
  req.param('oauth_verifier'), 
  function(error, oauthAccessToken, oauthAccessTokenSecret, results) {
    if(error) {
      res.json("Error:"+JSON.stringify(error));
    } else {
    // store the access token in the session
      req.session.oauthAccessToken = oauthAccessToken;
      req.session.oauthAccessTtokenSecret = oauthAccessTokenSecret;
      req.session.edamShard = results.edam_shard;
      req.session.edamUserId = results.edam_userId;
      req.session.edamExpires = results.edam_expires;
      req.session.edamNoteStoreUrl = results.edam_noteStoreUrl;
      req.session.edamWebApiUrlPrefix = results.edam_webApiUrlPrefix;
      res.json("Success");
    }
 });
});

我不知道我做错了什么...也许你们中的某些人对 evernote js sdk 有更多经验

【解决方案1】：

查看您的 OAuth 验证程序并确保其正确无误。我写了一个（相对未经测试的）正则表达式来正确获取 OAuth 验证器。我的（工作）代码在其他方面非常相似：

function getOauthVerifier(url) {
        var regex = new RegExp("[\\?&]oauth_verifier=([^&#]*)"),
        results = regex.exec(url);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

...

  else if (pathname == "/oauth"){
    client.getAccessToken(
      global.oauthToken, 
      global.oauthSecret, 
      getOauthVerifier(params.search), 
      function(error, oauthAccessToken, oauthAccessTokenSecret, results) {
        if(error) {
          console.log("error\n\n\n");
          console.log(error);
        }
        else {
          response.writeHead(200, {"Content-Type":"text/html"});
          response.write(oauthAccessToken);
          response.end();
        }   
      }
    );
  }
  else {
    response.writeHead(200, {"Content-Type":"text/html"});
    response.write("not a valid URL <a href=\"/\"> GO HOME </a>");
    response.end();
  }
