Xamarin:java.security.cert.CertPathValidatorException:找不到证书路径的信任锚 [英] Xamarin: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found

问题描述

在Xamarin中.我一直在尝试在Web API和Xamarin项目之间进行通信.这是我的控制器的代码:

In Xamarin. I've been trying to make communications between my Web API and my Xamarin project. Here's the code for my controller:

//  GET api/values
    public List<string> Get()
    {
        List<string> values = new List<string>();
        values.Add("Value 1");
        values.Add("Value 2");
        return values;
    }

这是我的 MainPage.xaml.cs

    public async void BindToListView()
    {
        HttpClient client = new HttpClient();
        var response = await client.GetStringAsync("https://10.0.2.2:#####/api/Values");
        var posts = JsonConvert.DeserializeObject<List<Posts>>(response);
        lv.ItemsSource = posts;
    }

每当我尝试同时运行我的Android应用程序和Web API应用程序时.我不断收到此异常:

Whenever I try to run both my Android application and my Web API Application. I keep getting this exception:

    Javax.Net.Ssl.SSLHandshakeException: 
'java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.'

我尝试将其粘贴到我的 MainActivity.cs 中，但仍然无法正常工作.

I've tried pasting this into my MainActivity.cs, but it still doesn't work.

ServicePointManager.ServerCertificateValidationCallback += (o, cert, chain, errors) => true;

几个月来我一直遇到这个问题，这让我发疯.我想念什么吗?我刚开始开发Xamarin应用程序，这是一个我似乎无法解决的问题.

I've been having this problem for months now, and its driving me crazy. Am I missing something? I'm fairly new in developing Xamarin applications, and this is a problem that I can't seem to resolve.

任何有关如何解决此问题的建议将不胜感激.感谢您抽出宝贵的时间阅读本文.

Any suggestions on how to resolve this problem will be greatly appreciated. Thanks for taking the time in reading this.

推荐答案

//Use this, it worked for me. 

HttpClient client;

public class datastore {
   var httpClientHandler = new HttpClientHandler();
            
   httpClientHandler.ServerCertificateCustomValidationCallback = 
   (message, cert, chain, errors) => { return true; };

   client = new HttpClient(httpClientHandler);
}

//... use the client to make request. it will bypass 
//the ssl certificates verification.
