Question

我正在尝试在reddit API上实现OAuth。我请求授权代码，单击链接，但是当我尝试执行POST以获取令牌时，我将“invalid_grant”作为我的错误。我在他们的文档中读到这意味着“代码已过期或已被使用”，但这是不可能的，因为我刚刚请求了代码。任何帮助表示赞赏！

这很好......

const CLIENT_ID="*****************";
const CLIENT_SECRET="**********************";

const TYPE="code";
const RANDOM_STRING="random_string";
const URI= encodeURIComponent('http://localhost:8080/api/reddit/callback');
const DURATION="temporary";
const SCOPE_STRING="identity";
const GRANT_TYPE='authorization_code';


const router = express.Router();

router.get('/login', function(req, res){
    console.log(`Redirecting to: https://www.reddit.com/api/v1/authorize?client_id=${CLIENT_ID}&response_type=${TYPE}&state=${RANDOM_STRING}&redirect_uri=${URI}&duration=${DURATION}&scope=${SCOPE_STRING}`);
    res.redirect(`https://www.reddit.com/api/v1/authorize?client_id=${CLIENT_ID}&response_type=${TYPE}&state=${RANDOM_STRING}&redirect_uri=${URI}&duration=${DURATION}&scope=${SCOPE_STRING}`);
});

错误就在这里......

router.get('/callback', function(req, res){
        if (!req.query.code) throw new Error('NoCodeProvided');
        if (req.query.state != RANDOM_STRING) throw new error('Mismatched strings');
        const CODE = req.query.code;
        request('https://www.reddit.com/api/v1/access_token', {
            method: 'POST',
            form: {
              grant_type: GRANT_TYPE,
              code: CODE,
              redirect_uri: URI
            },
            auth: {
              username: CLIENT_ID,
              password: CLIENT_SECRET
            }
          }, function (error, res, body){
            if (error){
              console.log("Error: " + error);
              return;
            }
            console.log(res);
            console.log(res.access_token);
            console.log(CODE);
            //const json = res.json();
            //res.redirect(`/?token=${json.access_token}`);
          });
        });

感谢reddit用户，我发现我的回调URI被编码了两次。更改为此修复...

const URI= 'http://localhost:8080/api/reddit/callback';
