Set custom cookie в Retrofit

Question

Есть ли способ установить пользовательский файл cookie для запросов на модернизацию?

Любое использование RequestInterceptor или любым другим способом?

Answer 1

Через retrofit.RequestInterceptor:

@Override 
public void intercept(RequestFacade request) {  
    request.addHeader("Cookie", "cookiename=cookievalue"); 
} 

Вы можете установить пользовательские RequestInterceptor следующим образом:

String cookieKey = ... 
String cookieValue = ... 

RestAdapter adapter = new RestAdapter.Builder() 
    .setRequestInterceptor(new RequestInterceptor() { 
     @Override 
     public void intercept(RequestFacade request) { 
     // assuming `cookieKey` and `cookieValue` are not null 
     request.addHeader("Cookie", cookieKey + "=" + cookieValue); 
     } 
    }) 
    .setServer("http://...") 
    .build(); 

YourService service = adapter.create(YourService.class); 

И читать любые куки, установленные на сервере, присоединить диспетчер печенья, как это:

OkHttpClient client = new OkHttpClient(); 
CustomCookieManager manager = new CustomCookieManager(); 
client.setCookieHandler(manager); 

RestAdapter adapter = new RestAdapter.Builder() 
    .setClient(new OkClient(client)) 
    ... 
    .build(); 

, где CustomCookieManager может выглядеть как t его:

public class CustomCookieManager extends CookieManager { 

    // The cookie key we're interested in.  
    private final String SESSION_KEY = "session-key"; 

    /** 
    * Creates a new instance of this cookie manager accepting all cookies. 
    */ 
    public CustomCookieManager() { 
    super.setCookiePolicy(CookiePolicy.ACCEPT_ALL); 
    } 

    @Override 
    public void put(URI uri, Map<String, List<String>> responseHeaders) throws IOException { 

    super.put(uri, responseHeaders); 

    if (responseHeaders == null || responseHeaders.get(Constants.SET_COOKIE_KEY) == null) { 
     // No cookies in this response, simply return from this method. 
     return; 
    } 

    // Yes, we've found cookies, inspect them for the key we're looking for. 
    for (String possibleSessionCookieValues : responseHeaders.get(Constants.SET_COOKIE_KEY)) { 

     if (possibleSessionCookieValues != null) { 

     for (String possibleSessionCookie : possibleSessionCookieValues.split(";")) { 

      if (possibleSessionCookie.startsWith(SESSION_KEY) && possibleSessionCookie.contains("=")) { 

      // We can safely get the index 1 of the array: we know it contains 
      // a '=' meaning it has at least 2 values after splitting. 
      String session = possibleSessionCookie.split("=")[1]; 

      // store `session` somewhere 

      return; 
      } 
     } 
     } 
    } 
    } 
} 

Answer 2

Я только начал с дооборудования, но так, как он обрабатывает куки, кажется, не быть на одном уровне с остальной частью библиотеки. Я ликвидируется делать что-то вроде этого:

// Set up system-wide CookieHandler to capture all cookies sent from server. 
final CookieManager cookieManager = new CookieManager(); 
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL); 
CookieHandler.setDefault(cookieManager); 

// Set up interceptor to include cookie value in the header. 
RequestInterceptor interceptor = new RequestInterceptor() { 
    @Override 
    public void intercept(RequestFacade request) { 
    for (HttpCookie cookie : cookieManager.getCookieStore().getCookies()) { 
     // Set up expiration in format desired by cookies 
     // (arbitrarily one hour from now). 
     Date expiration = new Date(System.currentTimeMillis() + 60 * 60 * 1000); 
     String expires = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz") 
      .format(expiration); 

     String cookieValue = cookie.getName() + "=" + cookie.getValue() + "; " + 
      "path=" + cookie.getPath() + "; " + 
      "domain=" + cookie.getDomain() + ";" + 
      "expires=" + expires; 

     request.addHeader("Cookie", cookieValue); 
    } 
    } 
}; 

RestAdapter restAdapter = new RestAdapter.Builder() 
    .setEndpoint("https://api.github.com") 
    .setRequestInterceptor(interceptor) // Set the interceptor 
    .build(); 

GitHubService service = restAdapter.create(GitHubService.class);

Это, как это делается для retrofit2

Gradle:

compile 'com.squareup.retrofit2:retrofit:2.1.0' 

Код:

static final class CookieInterceptor implements Interceptor { 
      private volatile String cookie; 

      public void setSessionCookie(String cookie) { 
       this.cookie = cookie; 
      } 

      @Override 
      public okhttp3.Response intercept(Chain chain) throws IOException { 
       Request request = chain.request(); 
       if (this.cookie != null) { 
        request = request.newBuilder() 
          .header("Cookie", this.cookie) 
          .build(); 
       } 
       return chain.proceed(request); 
      } 
} 


class Creator { 

    public static MyApi newApi() { 
     Gson gson = new GsonBuilder() 
       .setDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'") 
       .create(); 

     OkHttpClient okHttpClient = new OkHttpClient.Builder() 
       .addInterceptor(new CookieInterceptor()) 
       .build(); 

     Retrofit retrofit = new Retrofit.Builder() 
       .baseUrl(MyApi.URL) 
       .callFactory(okHttpClient) 
       .addConverterFactory(GsonConverterFactory.create(gson)) 
       .build(); 
     return retrofit.create(MyApi.class); 
    } 
}
