无法信任ubuntu 18.04.2 LTS中的开发https自签名证书

Question

我创建了一个REST API项目，并且正在尝试使用curl这样访问https端点：

$ dotnet new angular

$ curl -I -X GET 'https://localhost:5001/api/SampleData/WeatherForecasts'
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

我四处搜寻，这是我从dotnet提取证书并将其添加到我信任的CA证书存储库中的步骤：

这是我尝试添加证书的步骤

# export netcore development certificate
$ dotnet dev-certs https -ep ~/tmp/localhost.pfx -p somepassword

# convert it to crt
$ openssl pkcs12 -in ~/tmp/localhost.pfx -clcerts -nokeys -out ~/tmp/localhost.crt

# copy to a folder in /usr/local/share/ca-certificates/ 
$ cd /usr/local/share/ca-certificates/
$ sudo mkdir dotnet_devel
$ sudo chmod -R 755 dotnet_devel
$ mkdir dotnet_devel
$ cd dotnet_devel
$ sudo cp ~/tmp/localhost.crt .
$ sudo chmod -R 644 localhost.crt

# update CA trusted certificates repository
$ sudo update-ca-certificates
Updating certificates in /etc/ssl/certs...
1 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...

done.

我也尝试过这样设置CURL_CA_BUNDLE env var：

$ export CURL_CA_BUNDLE=/usr/local/share/ca-certificates/dotnet_devel/localhost.crt

我一直收到相同的卷曲错误，而且，Firefox和Chrome告诉我连接不安全

services.AddScoped(s =>
                {
                    // Creating the URI helper needs to wait until the JS Runtime is initialized, so defer it.
                    var uriHelper = s.GetRequiredService<NavigationManager>();
                    var handler = new HttpClientHandler();
                    handler.ServerCertificateCustomValidationCallback += (message, xcert, chain, errors) => true;
                    return new HttpClient(handler)
                    {
                        BaseAddress = new Uri(uriHelper.BaseUri)
                    };
                });
