.net core c# 忽略证书解决解决 The SSL co

在自己电脑能正常访问，在远程服务器上部署发现无法访问微信https网址。
检查了远程服务器的时间也是正常的，具体啥原因就懒得钻研了
测试用exe直接打开的方式部署正常，那么估计问题出在iis的部署方式的配置问题了，和之前遇到的配置跨域无效问题类似。
如果以web.config iis启动 则这么配置

<configuration>
  <system.net>
    <settings>
      <servicePointManager
          checkCertificateName="false"
          checkCertificateRevocationList="false"
      />
    </settings>
  </system.net>
</configuration>

代码中忽略证书

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

可以解决这个WebClient写法

         ServicePointManager.ServerCertificateValidationCallback = IgnoreCertificateValidationCallback;
            using WebClient MyWebClient = new();
            Encoding encode = Encoding.UTF8;
            MyWebClient.Headers.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.84 Safari/537.36");
            MyWebClient.Credentials = CredentialCache.DefaultCredentials;//获取或设置用于向Internet资源的请求进行身份验证的网络凭据
            String url = @$"https://baidu.com";
            Byte[] pageData = MyWebClient.DownloadData(url);
            String result = encode.GetString(pageData);

或者如果是HttpClient则可以细则么忽略

   using (var httpClientHandler = new HttpClientHandler())
            {
                httpClientHandler.ServerCertificateCustomValidationCallback = (message, cert, chain, sslPolicyErrors) =>
                {
                    if (sslPolicyErrors == SslPolicyErrors.None)
                    {
                        return true;   //Is valid
                    }

                 /*   if (cert.GetCertHashString() == "99E92D8447AEF30483B1D7527812C9B7B3A915A7")
                    {
                        return true;
                    }*/
                    return true;
                };
                using (var client = new HttpClient(httpClientHandler))
                {

     client.DefaultRequestHeaders.Add("User-Agent", "MyUserAgent");
                    client.DefaultRequestHeaders.Add("Authorization", "Bearer YourAccessToken");

}

}

}

web iis启动配置

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="coreapi.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
    </system.webServer>
  </location>
  <system.net>
    <settings>
      <servicePointManager
          checkCertificateName="false"
          checkCertificateRevocationList="false"
      />
    </settings>
  </system.net>
</configuration>
