使用“Flurl library”（在我的开发机器上）调用 https 端点时出现错误，所以我添加了“着名”

ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

跳过证书验证。

这似乎不适用于 Flurl（但适用于其他库，如“RestSharp”）

这是我的代码：

public async Task<object> MyMethod()
        {

            var client = new Url(baseUrl)
                                .AppendPathSegment(_endpoint)
                                .SetQueryParam("mbxId", 7)
                                .WithBasicAuth(username, password)
                                .WithHeader("cache-control", "no-cache")
                                .WithHeader("contenttype", "application/json; charset=utf-8")
                                .WithHeader("Accept", "text/html, application/xhtml+xml, image/jxr, */*");


            return await client.GetAsync();
        }

如果在拨打电话之前我打开“fiddler”并确认有关证书问题的消息警告（在这种情况下有效，如果我不先打开 fiddler，则不要）

ServicePointManager.ServerCertificateValidationCallback 是否具有全局范围？为什么 flurls 不考虑这个配置？

内部异常：

[System.Exception {Flurl.Http.FlurlHttpExceprion}]

信息：

   {"Security Error"} Request to https://demo.xxxxx.xxxxxxxxxxxxx.com:8181/dmlm4ws/ws/sessions/sessions?mbxId=7 failed. An error occurred while sending the request.

在此处查看此解决方案，该解决方案DefaultHttpClientFactory通过覆盖CreateMessageHandler 

public override HttpMessageHandler CreateMessageHandler() {
        return new HttpClientHandler {
            ServerCertificateCustomValidationCallback = (a, b, c, d) => true
        };
    }
