certificatePinner 无法使用 okhttp 抛出 SSLHandshakeException：CertPathValidatorException 未找到证书路径的信任锚

Question

我已从Square's own github Readme:获取代码

 @Throws(Exception::class)
 fun run() {
      val client = OkHttpClient.Builder()
                .certificatePinner(CertificatePinner.Builder()
                          .add("api.somewebsite.nl", "sha256/SOME_KEY/SOME_KEY")
                          .build())
                .build()

      val request = Request.Builder()
                .url("https://api.somewebsite.nl")
                .build()

      try {
           val response = client.newCall(request).execute()
           if (!response.isSuccessful) {
                Log.i("TestCode","is Not Successful")
                throw IOException("Unexpected code $response")
           } else {
                Log.i("TestCode","is Successful")
           }

           for (certificate in response.handshake()!!.peerCertificates()) {
                println(CertificatePinner.pin(certificate))
           }

      } catch (e: SSLHandshakeException) {
           e.printStackTrace()
      }
 }

当使用 Chrome 访问该网站时，它可以正常工作，表明该应用在特定手机上具有 Comodo CA 证书。对于 SHA256 引脚值，我选择了to this site。 this excellent walkthrough也提到了这个网站。

我使用了最新版本的库：

implementation "com.squareup.retrofit2:retrofit:2.5.0"
implementation "com.squareup.retrofit2:converter-moshi:2.5.0"
implementation "com.squareup.okhttp3:okhttp:3.14.1"
