如果临时字符串非常大,我会得到 java.io.IOException: Error writing to server at getInputStream
String tmp = js.deepSerialize(taskEx);
URL url = new URL("http://"
+ "localhost"
+ ":"
+ "8080"
+ "/Myproject/TestServletUpdated?command=startTask&taskeId=" +taskId + "'&jsonInput={\"result\":"
+ URLEncoder.encode(tmp) + "}");
URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream();
这是为什么?此调用转到 URL 中提到的 servlet。
