Retrofit 自定义Cookies

自定义Cookies拦截器：

public class CookiesInterceptor implements Interceptor{
    private Context context;

    public CookiesInterceptor(Context context) {
        this.context = context;
    }
    //重写拦截方法，处理自定义的Cookies信息
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        Request compressedRequest = request.newBuilder()
                .header("cookie", CookieUtil.getCookies(context))
                .build();
        Response response = chain.proceed(compressedRequest);
        CookieUtil.saveCookies(response.headers(), context);
        return response;
    }
}

CookieUtil则是一些自定义解析和生成方法以及SharedPreferences的存取，代码略
使用：

//设置拦截器，以用于自定义Cookies的设置
                mOkHttpClient.networkInterceptors()
                            .add(new CookiesInterceptor(context));

详细设置：

public abstract class BaseApi {
    public static final String API_SERVER = "服务器地址"
    private static final OkHttpClient mOkHttpClient = new OkHttpClient();
    private static Retrofit mRetrofit;

    protected static Retrofit getRetrofit() {
            if (Retrofit == null) {
                Context context = Application.getInstance().getApplicationContext();
                //设定30秒超时
                mOkHttpClient.setConnectTimeout(30, TimeUnit.SECONDS);
                //设置拦截器，以用于自定义Cookies的设置
                mOkHttpClient.networkInterceptors()
                            .add(new CookiesInterceptor(context));
                //设置缓存目录
                File cacheDirectory = new File(context.getCacheDir()
                                        .getAbsolutePath(), "HttpCache");
                Cache cache = new Cache(cacheDirectory, 20 * 1024 * 1024);
                mOkHttpClient.setCache(cache);
                //构建Retrofit
                mRetrofit = new Retrofit.Builder()
                        //配置服务器路径
                        .baseUrl(API_SERVER + "/")  
                        //设置日期解析格式，这样可以直接解析Date类型
                        .setDateFormat("yyyy-MM-dd HH:mm:ss")  
                        //配置转化库，默认是Gson
                        .addConverterFactory(ResponseConverterFactory.create())
                        //配置回调库，采用RxJava
                        .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                        //设置OKHttpClient为网络客户端
                        .client(mOkHttpClient)
                        .build();
            }
            return mRetrofit;
        }
}
