啓用認證手動

Question

目前我的客戶只有401響應的情況下，認證要求：

this.client.authenticator(new okhttp3.Authenticator() { 

     public Request authenticate(Route route, Response response) throws IOException { 
     String credentials = authenticator.getCredentials(); 
     if (credentials.equals(response.request().header("Authorization"))) { 
      throw new TraversonException(401, "Unauthorized", response.request().url().toString()); 
     } else { 
      defaultHeader("Authorization", credentials); 

      Request.Builder newRequest = response.request().newBuilder() 
           .headers(Headers.of(defaultHeaders)); 

      return newRequest.build(); 
     } 
}); 

但我想改變這種行爲，並能夠手動或每一次調用自動調用它呢？以某種方式可能嗎？

如果身份驗證是可預測需要的並且與代理無關，那麼解決方案是實現Interceptor而不是Authenticator。

OkHttpClient.Builder clientBuilder = ...; 
clientBuilder.networkInterceptors().add(0, myInterceptor); 
client = clientBuilder.build();

N.B.圍繞https://github.com/square/okhttp/pull/2458這個用例的可能支持進行了討論。當前Authenticator API的一個問題是它假定來自失敗（401）請求的響應。
