本文介绍了三种解决HTTP请求中中文乱码问题的方法：通过设置BufferedReader的字符集为UTF-8；将InputStream转换为UTF-8编码的String；以及将GBK编码的字符串转换为UTF-8编码。

方法一、解决中文乱码的问题(新)

//5.读取内容
//String responseMsg = postMethod.getResponseBodyAsString().trim();
//########################################################//
//解决报警告的问题WARN : org.apache.commons.httpclient.HttpMethodBase -
//Going to buffer response body of large or unknown size.
//Using getResponseBodyAsStream instead is recommended.
InputStream is = postMethod.getResponseBodyAsStream();
//like12 modified,20220530,解决中文乱码的问题
//BufferedReader br = new BufferedReader(new InputStreamReader(is));
BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
StringBuffer sb = new StringBuffer("");
String str= "";
while((str = br.readLine()) != null){
	sb.append(str);
}
String responseMsg = sb.toString();
//########################################################//
System.out.println("responseMsg:" + responseMsg);

方法二、解决中文乱码的问题

//解决中文乱码的问题
// InputStream转String(UTF-8)
public String inputStream2String(InputStream in) throws IOException {
	StringBuffer out = new StringBuffer();
	byte[] b = new byte[4096];
	for (int n; (n = in.read(b)) != -1;) {
	//like12 modified,20180713,解决中文乱码的bug
	//out.append(new String(b, 0, n));//默认GBK编码(系统编码)
	out.append(new String(b, 0, n, "UTF-8"));//指定编码格式
	}
	return out.toString();
}

方法三、GBK转UTF-8

//GBK转UTF-8
msg = new String(msg.getBytes("GBk"),"UTF-8");
System.out.println("msg2:" + msg);
