无法弄清楚何时打破循环 [英] Can't figure out when break the loop

问题描述

所有链接都指向此:

all links point on this:

while((c = is.read()) != -1) {
   // do something with the response
}

但是这种想法似乎是错误的，因为此循环是ENDLESS，我也尝试在响应后通过服务器"-1"发送-无济于事.我很困惑.
[只是试图从服务器接收响应]

but this conception seems like wrong, because this loop is ENDLESS, I also tried to send by server "-1" after response - not helped. I confused.
[Just trying to receive a response from the server]

推荐答案

井-1与"-1"不同.你在读什么? is.read()到达EOF时返回什么?

well -1 is not that same as "-1". What are you reading? What does is.read() return when it reaches EOF? that is what you want to look for.

是什么.当到达EOF时，read()返回?
字符串结束时is.read()返回255，但是:

What does is.read() return when it reaches EOF?
is.read() returns 255 when string was ended, but:

- 
while((c = is.read()) != 255) {
   // do something with the response
}

不是一个好的解决方案.
我认为唯一的方法是由服务器先传输字符串的LENGTH，然后再传输字符串.

is not a good solution.
I think the single way is to transfer by server LENGTH of string, and then, the string.
