请帮我整理一下。我在哪里失踪?在哪里更改我的代码
在wise趋势文档页面中提供的c代码的帮助下,我产生了这段代码
有问题的行是System.out.println(response.toString())。这基本上只读取一次响应。由于它直接脱离导线,因此无法重新读取。移除SOP,它应该可以工作 有问题的行是System.out.println(response.toString())。这基本上只读取一次响应。由于它直接脱离导线,因此无法重新读取。移除SOP,它应该可以工作 我忘了发送

看起来,您还有一个无限循环,因为有一个while(true)没有退出条件。看起来,您还有一个无限循环,因为有一个while(true)没有退出条件。
