okhttp3: java.lang.IllegalStateException: closed

苦惱了一天，看了這篇文章https://blog.csdn.net/ucxiii/article/details/52447945終于找到問題所在了，感謝部落客。，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的時候遇到這個問題，原因是使用了兩次response.body().string(),解決方法自然是隻用一次就可以了。
