Square API + iOS：OAuth 不工作？

Question

我正在使用 OAuthSwift pod 来实现 OAuth：

导入 OAuthSwift

class OAuthViewController: UIViewController {

  let oauthswift = OAuth2Swift(
    consumerKey:    "sq0idp-kXxs-e8ARPIPWeYYLTwH_w",
    consumerSecret: "sq0csp-4KnbcED665wDZ_sDYIN8E9scnYiJGqm4xxdnYtgxSKM",
    authorizeUrl:   "https://connect.squareup.com/oauth2/authorize",
    accessTokenUrl: "https://connect.squareup.com/oauth2/token",
    responseType:   "code"
  )

  @IBAction func signInButtonTapped(_ sender: AnyObject) {
    oauthswift.authorize(
      withCallbackURL: "http://localhost:5000/edmund",
      scope: "MERCHANT_PROFILE_READ",
      state: "",
      success: { credential, response, parameters -> Void in
        print("success")
        print(credential)
      },
      failure: { error in
        print("error")
        print(error._code)
        print(error._domain)
        print(error.localizedDescription)
      }
    )
  }

}

我的后端节点/Express 应用只是重定向以打开我的应用：

function edmund(req, resp) {
  console.log("resp");
  console.log(resp);
  resp.redirect(301, "indigoOMS:/");
}

这看起来可行：

但是，它在我的 OAuth 错误处理程序中打印出错误：错误 -5 OAuthSwift错误操作无法完成。（OAuthSwiftError 错误 -5。）

这是在我的节点日志上打印出来的内容：

我错过了什么？我觉得我做的一切都很好。

Answer 1

重定向 URL 需要是在服务器上托管的网页，尝试重定向到移动应用程序不会有好运。如果您正在构建供个人使用的应用程序，则可以改用您的个人访问令牌。您正在构建什么样的应用程序？

Answer 2

我认为您未能将任何参数传递给您的应用程序，因为您的 301 重定向将它们从 URI 中剥离。也许是这样的？

var URL = require('url');
...

function edmund(req, resp) {
  console.log("resp");
  console.log(resp);
  var queryString = URL.parse(req.url).query;
  resp.redirect(301, "indigoOMS:/?" + queryString);
}
