为什么我在 Windows 中将 \r\r\n 作为换行符而不是 \r\n 作为换行符 [英] Why I get \r\r\n as newline instead of \r\n as newline char in Windows
问题描述
我有下面的 readfile() java 函数来读取 .htm 文件
I have below readfile() java function to read .htm files
private String readfile(String inputDoc) throws IOException {
FileInputStream fis = null;
InputStreamReader isr = null;
String text = null;
//open input stream to file
fis = new FileInputStream(inputDoc);
isr = new InputStreamReader(fis, "UTF-8");
StringBuffer buffer = new StringBuffer();
int c;
while( (c = isr.read()) != -1 ) {
buffer.append((char)c);
}
text = buffer.toString();
isr.close();
return text;
}
这是输入文档的示例片段
Here is example snippet of input doc
<?xml version="1.0" encoding="utf-8"?><html>
<head>
出于某种原因，从 readfile() 返回的文本字符串是 <?xml version="1.0" encoding="utf-8"?><html>\r\r\n<head>
For some reason text string returned from readfile() is <?xml version="1.0" encoding="utf-8"?><html>\r\r\n<head>
但我希望它是 <?xml version="1.0" encoding="utf-8"?><html>\r\n<head>
正如其概述 此处 Windows 中的换行符 \r\n
as it is outlined here newline char in windows \r\n
我在 Windows 7 上的 IntelliJ Idea 中运行了上述函数.(IDEA 默认编码设置为 UTF-8)
I ran above function in IntelliJ Idea on Windows 7. (IDEA default encoding is set to UTF-8)
有谁知道为什么我从换行的 readfile(String inputDoc) 函数中得到这个奇怪的结果
Does anyone know why I get this weird result from readfile(String inputDoc) function for newline
推荐答案
你得到这个是因为它在输入文件中是这样的.尝试在十六进制编辑器中打开输入文件进行验证.
You get this because it is like this in the input file. Try to open the input file in a hex editor to verify.
