WordPress CPL 使用 JWT 令牌返回错误

Question

我必须通过 2 个过程验证用户。这是第一个：如果返回有效的令牌，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：<。路径"，第 0 行，位置 0。

错误是模糊的，因为所有地狱，我不知道这里的问题是什么。

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请求JWToken任务的内容

[AsyncStateMachine(typeof(<RequestJWToken>d__29))]
public Task RequestJWToken(string Username, string Password);
[Obsolete("Use JWT instead of Basic")]
Basic,
/// <summary>
/// JSON Web Token Authentication method. Need configure your site with this plugin https://wordpress.org/plugins/jwt-authentication-for-wp-rest-api/
/// </summary>
JWT

找到了方法

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;
}

Answer 1

它最终变成了非常愚蠢的东西

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

所以方法最终是

像这样的东西

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");
}
