http忽略证书错误

使用HttpClient请求https的url,但又没有本地证书,这时候可以用下面的方法忽略警告

  var httpclientHandler = new HttpClientHandler();
    httpclientHandler.ServerCertificateCustomValidationCallback = (message, cert, chain, error) => true;
    var httpClient = new HttpClient(httpclientHandler);

.nerCore IHttpClentFactory下

 //注入HttpClient，并且全局禁用cookie
        serviceCollection.AddHttpClient(typeof(ServiceProxy).FullName)
            .ConfigurePrimaryHttpMessageHandler(() => new HttpClientHandler
            {
                CookieContainer = new CookieContainer(),
                UseCookies = false
            });
