我需要知道如何添加授权饼干头的改造。我已经看到了类似的建议使用请求截取器等下面是什么，我想，但是这是正确的？首先，我已经需要一个RequestAdatper在第一时间获取会话ID左右。这只能通过请求适配器构建器来设置。但是，我需要做的请求只是为了获取会话ID在首位。我是否需要其余两个适配器之一获得的SessionID，我已经得着了一个又一个。我真正需要的是在接口的方法来设置cookie后，我得到它，但它似乎并没有出现这样的方法。这是越来越尴尬。这个问题很简单，普通不过。如何设置在改造授权cookie？我没有看到这个FAQ或教程。

  RequestInterceptor requestInterceptor =新RequestInterceptor（）
{
   @覆盖
   公共无效拦截（RequestFacade要求）{
        request.addHeader（设置Cookie，的sessionId =+ sessionIdentifier）;
   }
 };


RestAdapter.Builder（）setServer（serverURL使用）.. setRequestIntercepter（requestIntercepter）.build（）。

//但是我没有的sessionId时，这是首次发布?????
 

解决方案

请引用拦截器，并把它作为一个单身，就像您是 RestAdapter 本身。

 公共类ApiHeaders实现RequestInterceptor {
  私人字符串的sessionId;

  公共无效setSessionId（字符串的sessionId）{
    this.sessionId =的sessionId;
  }

  公共无效clearSessionId（）{
    的sessionId = NULL;
  }

  @覆盖公共无效拦截（RequestFacade要求）{
    如果（的sessionId！= NULL）{
      request.setHeader（...）;
    }
  }
}
 

现在，只要您的验证通话后称 setSessionId 。所有后续请求将包含头。

I need to know how to add an authorization cookie header in retrofit. I have seen advice like using request intercepter etc. Below is what I am trying, but is this correct? First of all I already needed a RequestAdatper to get the session id the first time around. This can only be set by the builder of the request adapter. But I needed to make a request just to get the session id in the first place. Do I need two rest adapters one to get the sessionId and another one after I have obtained it. What I really need is a method on adapter to set the cookie after I get it but it does not appear to be such a method. This is getting awkward. The question is simple and common enough. How do I set authorization cookie in retrofit? I don't see this in FAQ or tutorials.

RequestInterceptor requestInterceptor = new RequestInterceptor()
{   
   @Override
   public void intercept(RequestFacade request) {
        request.addHeader("Set-Cookie", "sessionId="+sessionIdentifier);
   }
 };


RestAdapter.Builder().setServer(serverURL)..setRequestIntercepter(requestIntercepter).build();  

// but I don't have sessionId when this is first issued ?????

Keep a reference to the interceptor and treat it as a singleton like you would be RestAdapter itself.

public class ApiHeaders implements RequestInterceptor {
  private String sessionId;

  public void setSessionId(String sessionId) {
    this.sessionId = sessionId;
  }

  public void clearSessionId() {
    sessionId = null;
  }

  @Override public void intercept(RequestFacade request) {
    if (sessionId != null) {
      request.setHeader(...);
    }
  }
}

Now, simply call setSessionId after your authentication call. All subsequent requests will include the header.
