javascript - 无法生成 linkedIn 的访问 token

Question

Console.log(code) 工作正常，但之后我收到错误:

{"error":"invalid_redirect_uri","error_description":"Unable to retrieve access token: appid/redirect uri/code verifier does not match authorization code. Or authorization code expired. Or external member binding exists"}.

`app.use(bodyParser.urlencoded({extended:true}));
app.set("view engine","ejs");
app.use(express.static(__dirname + "/public"));
app.use(methodOverride("_method"));


app.get('/home',function(req,res){
    res.render('home');
})

app.get('/profile',function(req,res){
    console.log(req.query.code);
    var code = req.query.code;
    request.post({url:'https://www.linkedin.com/oauth/v2/accessToken', 
    form: 
    {grant_type:'authorization_code',code:code, 
    redirect_uri:'http%3A%2F%2Flocalhost:3000%2Fprofile', 
    client_id:'value', client_secret:'value'}}, 
    function(err,httpResponse,body){ console.log(httpResponse.body); })`
})

我看到代码:'$code'但也许它必须是:

code:`${code}`

你的redirect_uri指向本地主机，也许这就是问题所在。
