我想将 XERO 集成到 WebAPI C# 有人可以为我提供 oauth2 的示例代码吗

Question

I have tried the below

        XeroConfiguration xeroConfig = new XeroConfiguration();
        xeroConfig.ClientId = "****";
        xeroConfig.ClientSecret = "****";
        xeroConfig.CallbackUri = new Uri("http://localhost"); //default for standard webapi template
        xeroConfig.Scope = "openid profile email files accounting.transactions accounting.contacts offline_access";
        var client2 = new XeroClient(xeroConfig, httpClientFactory);
        var test = client2.BuildLoginUri();

        return Redirect(client2.BuildLoginUri());

After redirection it is giving below error Error code: 500 Error: unauthorized_client: Invalid redirect_uri

Answer 1

It is because you have registered your app in the Authorization Server using a different redirect URI and in the above you are using a different redirect URI which will be validated by the Authorization Server and on mismatch, it is throwing you the Error.

You have to register your app with the Redirect URI that you will be using

Ex: If your app is running in http://localhost:6500 and your redirect URI to receive the token and process is http://localhost:6500/login . You have to provide this value to the Authorization Server.

ex: The setting would look like

xeroConfig.CallbackUri = new Uri("http://localhost:6500/login")
