Xamarin.Forms HTTPS和自签名证书问题

问题描述

我正在使用Xamarin.Forms，我的优先级是UWP。我正在尝试通过 System.Net.Http.HttpClient 发布帖子请求，我的代码看起来像这样

  public async Task< LoginResponse>登录（用户用户）
 {
 HttpClient client = await GetClient（）; 
 
 var response = await client.PostAsync（Url，new StringContent（JsonConvert.SerializeObject（user），Encoding.UTF8，application / json））; 
 var mobileResult = await response.Content.ReadAsStringAsync（）; 
 var result = JsonConvert.DeserializeObject< LoginResponse>（mobileResult）; 
 
返回结果; 
} 
  

当我提出请求时，我收到此错误

我认为自签名SSL会导致问题。我知道我可以使用Windows.Web HttpClient来忽略SSL错误，但由于一些问题，现在不可能。
我该如何解决这个问题？在此先感谢。

解决方案

使用自签名证书的一种解决方法是在初始化HttpClient之前插入以下代码，以便忽略SSL证书错误：

  ServicePointManager.ServerCertificateValidationCallback + =（sender，cert，chain，sslPolicyErrors）=>真正; 
  

确保包含System.Net。

I am using Xamarin.Forms and my priority is UWP. I am trying to make a post request via System.Net.Http.HttpClient and my code looks like this

public async Task<LoginResponse> Login(User user)
{
    HttpClient client = await GetClient();

    var response = await client.PostAsync(Url, new StringContent(JsonConvert.SerializeObject(user), Encoding.UTF8, "application/json"));
    var mobileResult = await response.Content.ReadAsStringAsync();
    var result = JsonConvert.DeserializeObject<LoginResponse>(mobileResult);

    return result;
}

When i make the request i am getting this error

I think the self-signed SSL causing the problem. I know i can use Windows.Web HttpClient to ignore SSL errors but due to some problems it is not possible now.How can i solve this problem ? Thanks in advance.

解决方案

A workaround for using self-signed certificates is to insert the following code before initialising your HttpClient in order to ignore SSL certificate errors:

ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;

Make sure to include System.Net.

Hope this helps.
