java.lang.IllegalStateException: closed

使用okhttp3的时候遇到的异常：java.lang.IllegalStateException: closed。原因是流已经关闭，所以无法再进行操作。

public abstract class myCallback extends Callback<Bundle> {@Overridepublic Bundle parseNetworkResponse(Response response, int id) throws Exception {//打印log，查看Log.d("test", response.body().string());//获取body进行逻辑处理String result = response.body().string();backJsonObject = new JSONObject(result);}
}

public final String string() throws IOException {BufferedSource source = source();try {Charset charset = Util.bomAwareCharset(source, charset());return source.readString(charset);} finally {Util.closeQuietly(source);}}

注意finally中的Util.closeQuietly(source);它是一个关闭流的工具方法，所以此时你再次调用这个方法，就会报文章开头的错误：流已经关闭。所以请不要多次调用response.body().string()；
