我正在寻找使用Android应用程序使用带有ssl的模拟网络服务器编写OkHttpClient的集成测试。我能够使用HeldCertificate和HandshakeCertificates实现此目的，但是我对使用自签名证书感兴趣。尝试使用自签名证书时，握手失败。下面是重现此内容的详细信息。
a。使用此命令创建的自签名证书
openssl req -x509 -out localhost.crt -keyout localhost.key -newkey rsa:2048 -nodes -sha256 -subj '/CN=localhost' -extensions EXT -config <( \
printf "[dn]\nCN=localhost\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:localhost\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")
b。转换为der for android。 openssl x509 -in localhost.crt -outform der -out localhost.der.crt
c。使用此处提供的代码https://gist.github.com/erickok/7692592来获取SSLSocketFactory，以将其传递给mockWebserver.useHttps（）和OkHttpClientBuilder..sslSocketFactory（）。
尝试发送和接收非常简单的请求时遇到握手失败。
