找不到证书路径的信任锚点[Osian.Forms]

当我试图 职位 使用 打开VPN

注: 当我尝试在连接了Open VPN的平板电脑上使用swagger访问API时,API正在连接并运行良好,只是移动应用程序无法使用它。(在Xamarin应用程序中,我们得到了例外。

代码:

var uri = prepareLoginUri("/Login/Login");
var body = new { username, password };
var json = JsonConvert.SerializeObject(body);
var content = new StringContent(json, Encoding.UTF8, "application/json");

var response = await _client.PostAsync(uri, content);

例外情况:

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

已找到此异常的解决方案,但未修复问题:

https://forums.xamarin.com/discussion/91782/trust-anchor-for-certification-path-not-found

根据此链接中的建议,我在中添加了以下代码 主要活动cs

HttpClientHandler clientHandler = new HttpClientHandler();
clientHandler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };
_client = new HttpClient(clientHandler);

这解决了异常,但现在我从API得到的响应是 404未找到 .

StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.HttpConnection+HttpConnectionResponseContent

但在招摇撞骗中,API运行得非常好。
