如何在Retrofit请求里添加Cookie

你可以自定义一个RequestIntercaptor:

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);

从服务器读取cookies再交给cookie manager管理：

OkHttpClient client = new OkHttpClient();CustomCookieManager manager = new CustomCookieManager();client.setCookieHandler(manager);RestAdapter adapter = new RestAdapter.Builder()    .setClient(new OkClient(client))    ...    .build();

CustomeCookieManager如下:

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;          }        }      }    }  }}
