okhttp3: java.lang.IllegalStateException: closed

苦恼了一天，看了这篇文章https://blog.csdn.net/ucxiii/article/details/52447945终于找到问题所在了，感谢博主。，04-06 20:26:55.461 7632-7675/com.littlegold.littlegoldweather E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher

                                                                                    at java.lang.Thread.run(Thread.java:841) 使用okhttp3的时候遇到这个问题，原因是使用了两次response.body().string(),解决方法自然是只用一次就可以了。
