我有一个奇怪的故障,我不能两次拨打同一个网络电话。
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
try {
HttpResponse response = client.execute(post, new BasicHttpContext());
我第一次运行网络调用它工作得很好,数据被返回。我第二次运行网络调用(我在这里运行断点)它到达 HttpResponse 对象,运行网络调用,但随后立即跳转到IOException
catch。
post
对象每次都有相同的数据,cookies都包括在内。
我周围没有任何了解服务器(运行drupal)的人,但这似乎是服务器问题。
有人可以解释为什么会发生这种情况吗?为什么我会被禁止第二次取回数据?
为了进一步说明问题,如果我突破响应对象,我可以看到它可能会返回""
而不是数据。如果这有帮助的话
