Java.IO.EOFException 승인을 통해 프록시를 통해 OkHttpClient를 읽는 중

Question

HttpUrlConnection (InputStream에 액세스 할 때)에서 데이터를 읽으려고 할 때 Java.IO.EOFException이 발생합니다. OkHttp 라이브러리에서 xamarin을 사용하면 응용 프로그램이 genymotion 안드로이드 4.2.2

와 에뮬레이터 다음은 샘플 코드 (C#을)입니다 :

// ... 
     var okHttpClient = CreateHttpClient(); 
     var conn = okHttpClient.Open(new URL(address)); 
     var inputStream = conn.InputStream; //here is the exception 
    // ... 

    private OkHttpClient CreateHttpClient() 
    { 
     OkHttpClient client = new OkHttpClient(); 
     client.SetProxy(new Proxy(Proxy.Type.Http, new InetSocketAddress(Host, Port))); 
     client.SetAuthenticator(new MyAuthenticator(User, Password));    

     return client; 
    } 

    private class MyAuthenticator: Java.Lang.Object, IOkAuthenticator 
    { 
     private readonly string _user; 
     private readonly string _password; 

     public MyAuthenticator(string user, string password) 
     { 
      _user = user; 
      _password = password; 
     } 

     public OkAuthenticatorCredential Authenticate(Proxy p0, URL p1, IList<OkAuthenticatorChallenge> p2) 
     { 
      return OkAuthenticatorCredential.Basic(null, null); //this is never called 
     } 

     public OkAuthenticatorCredential AuthenticateProxy(Proxy p0, URL p1, IList<OkAuthenticatorChallenge> p2) 
     { 
      return OkAuthenticatorCredential.Basic(_user, _password); 
     } 
    } 

인증 모든 작동하지 않고 프록시는

. 나는 닷넷 모노 웹 클라이언트를 사용하는 경우

("가까운", "연결")는 프록시 인증과 함께 작동 (하지만 가능하면 모노 WebClient를 사용하지 않는 이유가)

해결 conn.SetRequestProperty을; 도움이 안돼.

Answer 1

은 터널을 구축해야하는 HTTPS URL을 달성하기 위해 HTTP 프록시를 사용합니다. 이것은 실패하고있다. 프록시가 터널을 생성하지 않습니다. 사용중인 프록시가 도달하려는 URL을 지원하는지 확인 했습니까?

Answer 2

오늘 같은 오류가 발생했습니다. 내 URL 문자열에 공백이 있습니다. % 20 (으)로 변경 한 후 문제가 사라졌습니다.
