我在用HttpURLConection发送POST请求时，并未包含中文，但自己测试时收到的请求前面总是包含几个乱码，
求高手解决！
代码如下：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.ObjectOutputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class HttpUtil {
/**
* 发送http POST请求
* @param httpUrl 请求URL
* @param httpContext 请求报文主体内容
* @return
* @throws IOException
*/
public static String sendPost(String httpUrl,String httpContext) throws IOException{
URL url = new URL(httpUrl);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
// 设置是否向httpUrlConnection输出，因为这个是post请求，参数要放在http正文内，因此需要设为true,默认情况下是false;
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type","application/json; encoding=utf-8");
connection.setRequestProperty("Connection", "keep-alive");
OutputStream out = connection.getOutputStream();
// 现在通过输出流对象构建对象输出流对象，以实现输出可序列化的对象。
ObjectOutputStream objOut = new ObjectOutputStream(out);
objOut.writeObject(httpContext); // 向对象输出流写出数据，这些数据将存到内存缓冲区中
out.close();
objOut.close(); // 关闭对象输出流
InputStream in = connection.getInputStream();
InputStreamReader inr = new InputStreamReader(in);
BufferedReader reader = new BufferedReader(inr);
StringBuffer result = new StringBuffer();
String temp;
while((temp = reader.readLine()) != null){
result.append(temp);
}
in.close();
return result.toString();
}
}
