[英]Java Buffered Reader Reads In Part of the URL to String then Hangs (Is there a size limit?)
I am trying to read a URL into a String and it starts reading in the URL and then just stops at the same line every time and hangs. 我正在尝试将URL读入字符串,它开始在URL中读取,然后每次都停在同一行并挂起。 This happens with any URL and it happens when I run the program from the command line on Windows 7. When I run the same program in Eclipse it never hangs and reads in the entire website.
任何URL都会发生这种情况,当我在Windows 7上从命令行运行该程序时就会发生这种情况。当我在Eclipse中运行相同的程序时,它永远不会挂起并读取整个网站。
It always gets to "got to line 2" and inside of the while loop but never to "line 3". 它总是在“进入第2行”和while循环内部,而从不进入“第3行”。
Here is the code I am using below. 这是我在下面使用的代码。 Is there some type of a size limit or something when doing it right through Windows on the command line?
通过命令行在Windows上执行大小限制时是否有某种类型的限制?
URL link = new URL("http://www.yahoo.com");
System.out.println("got to this line 1");
BufferedReader in = new BufferedReader(new InputStreamReader(link.openStream()));
System.out.println("got to this line 2");
//InputStream in = link.openStream();
String inputLine = "";
int count = 0;
while ((inputLine = in.readLine()) != null)
{
site = site + "\n" + inputLine;
System.out.println(inputLine);
}
System.out.println("exited the while loop.");
in.close();
System.out.println("got to this line 3");
I took that code, put it in a main method, added a site
variable as String site = "";
我获取了该代码,并将其放在main方法中,并添加了一个
site
变量,如String site = "";
, compiled it with IntelliJ, and ran it from a Windows 7 command prompt, and it worked fine: ,并使用IntelliJ对其进行编译,然后从Windows 7命令提示符下运行它,效果很好:
> java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
Output of the program: 程序输出:
got to this line 1
got to this line 2
<all of the page source>
exited the while loop.
got to this line 3
Does it work the same if you comment out the line that prints out each line as its read in? 如果您注释掉在读入时打印出每一行的行,它的工作原理是否相同?
