Retrofit+OkHttp实现Cookie持久化，RxJava方式

通过Interceptor实现cookie持久化，相关三方库：PersistentCookieJar

将cookie存储到本地

public class ReceivedCookiesInterceptor implements Interceptor {

    @Override
    public Response intercept(@NonNull Chain chain) throws IOException {
        Response originalResponse = chain.proceed(chain.request());
        if (!originalResponse.headers("set-cookie").isEmpty()) {
            final StringBuffer cookieBuffer = new StringBuffer();
            Observable.from(originalResponse.headers("set-cookie"))
                    .map(new Func1<String, String>() {
                        @Override
                        public String call(String s) {
                            String[] cookieArray = s.split(";");
                            return cookieArray[0];
                        }
                    })
                    .subscribe(new Action1<String>() {
                        @Override
                        public void call(String cookie) {
                            cookieBuffer.append(cookie).append(";");
                        }
                    });
            SpUtil.setString(GlobalConstant.COOKIES, cookieBuffer.toString());
        }
        return originalResponse;
    }

}

将本地的cookie追加到http请求头中

public class AddCookiesInterceptor implements Interceptor {

    @Override
    public Response intercept(@NonNull Chain chain) throws IOException {
        final Request.Builder builder = chain.request().newBuilder();
        Observable.just(SpUtil.getString(GlobalConstant.COOKIES))
                .subscribe(new Action1<String>() {
                    @Override
                    public void call(String cookie) {
                        //添加cookie
                        builder.addHeader("cookie", cookie);
                    }
                });
        return chain.proceed(builder.build());
    }

}

OkHttp配置

OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .addInterceptor(httpLoggingInterceptor)

                .addInterceptor(new ReceivedCookiesInterceptor())
                .addInterceptor(new AddCookiesInterceptor())

                .connectTimeout(15, TimeUnit.SECONDS)
                .build();
