使用OKHTTP3认证固定进行改造

Question

I am using Retrofit 1.9 with OKHTTP3 client and I am trying to add certification pinning. Below is the relevant code:

String hostname = "xxxxxx.xx";

CertificatePinner certificatePinner = new CertificatePinner.Builder()
    .add(hostname, "sha1/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=")
    .build();

OkHttpClient client = new OkHttpClient.Builder()
     .certificatePinner(certificatePinner)
     .build();

return new RestAdapter.Builder()
     .setRequestInterceptor(request -> {
         request.addHeader("CONTENT-TYPE", "application/json");
     })
     .setEndpoint("https://xxxxxxxxxxxx").
     .setClient(new Ok3Client(client))
     .build();

Unfortunately it doesn't seem to be working. I don't have the

"javax.net.ssl.SSLPeerUnverifiedException: Certificate pinning failure!"

exception and even my host or SHA is incorrect. Can anyone explain why?

Answer 1

A couple things to check, since you've redacted the parts were mistakes are common, I can't tell for certain if these are you issue, but both mistakes will cause no pinning with no logs.

1) For hostname in your CertificatePinner , make sure it is just the host name, like "www.example.com", and not a url " https://www.example.com ".
2) For .setEndpoint("xxxxxxxxxxxx") , make sure you endpoint is https , there are no certs checked on http so no logs.
