我们如何在控制台应用程序中验证 Quickbooks Online？答案

【问题标题】：How do we authenticate Quickbooks Online in a Console Application?我们如何在控制台应用程序中验证 Quickbooks Online？

【问题描述】：

我正在尝试在需要首先获取持有者令牌的控制台应用程序中调用 Quick Books Online API。下面是代码 sn-p，我在其中尝试首先获取授权代码以进行后续访问令牌调用。我收到的是 HTML 响应，而不是带有验证码的 json 对象。

另外，QBO 支持哪些资助类型？

HttpClientHandler httpClientHandler = new HttpClientHandler();            
HttpClient httpClient = new HttpClient(httpClientHandler,false);
httpClient.BaseAddress = new Uri("https://appcenter.intuit.com/connect/oauth2");

List<KeyValuePair<string, string>> param = new List<KeyValuePair<string, string>>();
param.Add(new KeyValuePair<string, string>("response_type","code"));
param.Add(new KeyValuePair<string, string>("client_id", "AB5********26"));
param.Add(new KeyValuePair<string, string>("scope", "com.intuit.quickbooks.accounting"));
param.Add(new KeyValuePair<string, string>("redirect_uri", "https://developer.intuit.com/v2/OAuth2Playground/RedirectUrl"));

var resp = httpClient.PostAsync("", new FormUrlEncodedContent(param)).GetAwaiter().GetResult();
var result = resp.Content.ReadAsStringAsync().GetAwaiter().GetResult();

我发送的请求的 HTML 响应..

【问题讨论】：

通常要获取不记名令牌，您首先使用 REST 调用身份验证 API（即使用登录名和密码调用 Web 服务），然后它会返回不记名令牌。然后在后续调用中使用它。
您是否经历过并剖析了它的工作原理？ developer.intuit.com/app/developer/qbo/docs/… 原样，您的问题不够详细，任何人都无法回答

using Intuit.Ipp.Core;
using Intuit.Ipp.OAuth2PlatformClient;
using Intuit.Ipp.Security;
using System;
using System.Collections.Generic;
using System.Text;

namespace QuickBooksToken
{
    public class GetAccessTokenQbo
    {
        public static string GetAccessToken()
        {
            System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

            var oauth2Client = new OAuth2Client(client Id, client Secret, "https://developer.intuit.com/v2/OAuth2Playground/RedirectUrl", environment); // environment is “sandbox” or “production”

            var previousRefreshToken = ReadRefreshTokenFromWhereItIsStored();
            var tokenResp = oauth2Client.RefreshTokenAsync(previousRefreshToken);
            tokenResp.Wait();
            var data = tokenResp.Result;

            if (!String.IsNullOrEmpty(data.Error) || String.IsNullOrEmpty(data.RefreshToken) ||
                  String.IsNullOrEmpty(data.AccessToken))
            {
                throw new Exception("Refresh token failed - " + data.Error);
            }

            // If we've got a new refresh_token store it in the file
            if (previousRefreshToken != data.RefreshToken)
            {
                Console.WriteLine("Writing new refresh token : " + data.RefreshToken);
                WriteNewRefreshTokenToWhereItIsStored(data.RefreshToken);
return data.AccessToken
            }
            return data.AccessToken;
        }

        private static string ReadRefreshTokenFromWhereItIsStored()
        {
            return "Refresh token";       //hard code your refresh token
        }

        private static string WriteNewRefreshTokenToWhereItIsStored(string refreshToken)
        {
            return refreshToken;
        }

        public static ServiceContext GetServiceContext()
        {
            string accessToken = GetAccessToken();// Code from above
            var oauthValidator = new OAuth2RequestValidator(accessToken);

            ServiceContext qboContext = new ServiceContext(realm Id, IntuitServicesType.QBO, oauthValidator);

            return qboContext;
        }
    }
}

安装此 nuget 库 IppDotNetSdkForQuickBooksApiV3（版本 14.4.4）。在我的情况下，环境是沙箱。您可以使用 (https://developer.intuit.com/app/developer/playground) 链接获取客户端密码、客户端 ID、领域 ID 和新刷新令牌的值，以便在您的 c# 应用程序中硬编码。
