致命异常：java.lang.NullPointerException 在com.richrelevance.internal.net.HttpUrlConnectionExecutor.getConnection（HttpUrlConnectionExecutor.java:87）在com.richrelevance.internal.net.HttpUrlConnectionExecutor.execute（HttpUrlConnectionExecutor.java:40）在com.richrelevance.internal.net.WebRequestManager.execute（WebRequestManager.java:172）在com.richrelevance.internal.net.WebRequestManager $ 1.run（WebRequestManager.java:193） at java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1112） at java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:587）在com.richrelevance.internal.net.WebRequestManager $ 2 $ 1.run（WebRequestManager.java:219）在java.lang.Thread.run（Thread.java:841）
