Question

我必须发送HTTPS POST请求。我创建了一个库类来发送HTTPS POST请求。我有2个程序调用此库类：

我的主程序（IdentityServer）
我的考试班

两个程序都只使用给定参数调用库类（将在POST正文上使用），然后库类执行请求。

问题是，当在我的测试类上运行它时，它可以正常工作。但是，对于IdentityServer，它会引发以下错误“ System.Net.Http.WinHttpException”。

我注意到测试类和IdentityServer之间的唯一区别是它们的“目标框架”：

IdentityServer（.NET Core 2.0）
测试类（.NET Framework 4.6.1）
类库（.NET Framework 4.6.1）

这是我发送请求的简单代码：

public static async Task<HttpStatusCode> Send(String destination, String message, String accountUsername, String accountPassword, String senderPhoneNumber)
    {

        var values = new Dictionary<string, string>
        {
            { "username", accountUsername },
            { "password", accountPassword },
            { "src", senderPhoneNumber },
            { "dst", destination },
            { "text", message },
            { "srr", "3" }
        };

        var content = new FormUrlEncodedContent(values);

        HttpStatusCode responseStatus = HttpStatusCode.NotAcceptable;

        try
        {
            HttpClient client = new HttpClient();

            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;

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

            var response = await client.PostAsync("TARGET_URL", content);
            var responseString = await response.Content.ReadAsStringAsync();
            responseStatus = response.StatusCode;
        }
        catch (WebException we)
        {
            string error = we.ToString();
        }
        catch (Exception e)
        {
            string error = e.ToString();
        }
        return responseStatus;
    }

我忽略了来自目标服务器的证书，因为它们的证书无效。

但是，正如我所说的，用我的测试类调用它就可以了。

从IdentityServer调用时引发的完整错误如下：
