WordPress CPL 使用 JWT 令牌返回错误答案

【问题描述】：

我必须通过 2 个流程验证用户。这是第一个：如果返回了有效的令牌，我将进入第 2 阶段，这只是拉取客户列表，然后关联用户名。获取客户的 ID 等，然后将其保存到本地存储以保留用户并允许更简单的订单发送。

错误：

解析值时遇到意外字符：

错误非常模糊，我不知道问题出在哪里。

  class WpApiCredentials
    {
        public static string SiteUri = "http://TheSite.co.za/";
        public static string WordPressUri = $"https://public-api.wordpress.com/wp/v2/sites/{SiteUri}/";
        public static string Username = "Name";
        public static string Password = "password";
    }


 WpApiCredentials.Username = Usernamelabel.Text;
 WpApiCredentials.Password = PasswordLabel.Text;


var client = new WordPressClient(WpApiCredentials.SiteUri);
client.AuthMethod = AuthMethod.JWT;
await client.RequestJWToken(WpApiCredentials.Username, WpApiCredentials.Password);

       
 var isValidToken = await client.IsValidJWToken();

 if (isValidToken)
            {

             await App.Current.MainPage.DisplayAlert("Token Received", "Phase 1 is done ", "OK");
             Login_Phase2();
                   
            }
            else
            {
                await App.Current.MainPage.DisplayAlert("Empty Values", "Token not Found", "OK");
            }

这是我可以找到的关于 RequestJWToken 任务的内容

        [AsyncStateMachine(typeof(<RequestJWToken>d__29))]
        public Task RequestJWToken(string Username, string Password);

[Obsolete("Use JWT instead of Basic")]
        Basic,

找到方法


public async Task RequestJWToken(string Username, string Password)
        {
            var route = $"{_jwtPath}token";
            var formContent = new FormUrlEncodedContent(new[]
                {
                    new KeyValuePair<string, string>("username", Username),
                    new KeyValuePair<string, string>("password", Password)
                });

            (JWTUser jwtUser, HttpResponseMessage response) = await _httpHelper.PostRequest<JWTUser>(route, formContent, false).ConfigureAwait(false);
            //JWToken = jwtUser?.Token;
            _httpHelper.JWToken = jwtUser?.Token;
        }

【问题讨论】：

这行代码崩溃了，有什么异常？
等待 client.RequestJWToken(WpApiCredentials.Username, WpApiCredentials.Password);
现在也出现此错误“获取响应流时出错 (ReadDoneAsync2): ReceiveFailure”
我猜您正在 client.RequestJWToken() 中进行某种反序列化，如果是这种情况，则此错误可能意味着您收到无效的 JSON 响应，可能是由于来自服务器。如果不是这种情况，您需要在 client.RequestJWToken() 中发布代码，以便我们更好地查看它

【解决方案1】：

它最终变得非常愚蠢

如果您注意到公共静态字符串 SiteUri = "http://TheSite.co.za/";最后没有 /wp-json。

所以方法最终是

类似的东西


 var client = new WordPressClient("http://Your-Site/wp-json/");
            client.AuthMethod = AuthMethod.JWT;
            await client.RequestJWToken(TheUserName, ThePassword);

            var x = client;
            var isValidToken = await client.IsValidJWToken();



            WpApiCredentials.token = client.GetToken();

            if (isValidToken)
            {

                Login_Phase2();
            }
            else
            {

                await App.Current.MainPage.DisplayAlert("Empty Values", "Token not Found", "OK");
            }
