httpclient 中文乱码的解决方案

最近写个httpclient post的方法如下
 
public static void sendData(String url, String value[], String key[])throws IOException {HttpClient client = new HttpClient();// 设置代理服务器地址和端口 client.getHostConfiguration().setProxy("172.17.18.80",8080);// client.getHostConfiguration().setHost(host, port, "http");PostMethod postMethod = new PostMethod(url);NameValuePair p1 = new NameValuePair(key[0], value[0]);NameValuePair p2 = new NameValuePair(key[1], value[1]);postMethod.setRequestBody(new NameValuePair[] { p1, p2 });postMethod.setRequestHeader("Content-Type", "text/html;charset=gb2312");// 使用POST方式提交数据client.executeMethod(postMethod);// 打印服务器返回的状态logger.info("服务器返回的状态=" + postMethod.getStatusLine());// 打印结果页面String response = new String(postMethod.getResponseBodyAsString().getBytes("gb2312"));// 打印返回的信息logger.info("返回的信息=" + response);// 释放连接postMethod.releaseConnection();} 
 使用 postMethod.setRequestHeader("Content-Type", "text/html;charset=gb2312");  客户端接受的值是个null
 后改成  postMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "gb2312"); 问题解决 很是奇怪
 
完整代码如下
public static void sendData(String url, String value[], String key[])throws IOException {HttpClient client = new HttpClient();// 设置代理服务器地址和端口// client.getHostConfiguration().setProxy("172.17.18.80",8080);// client.getHostConfiguration().setHost(host, port, "http");PostMethod postMethod = new PostMethod(url);postMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "gb2312");NameValuePair p1 = new NameValuePair(key[0], value[0]);NameValuePair p2 = new NameValuePair(key[1], value[1]);postMethod.setRequestBody(new NameValuePair[] { p1, p2 });// 使用POST方式提交数据client.executeMethod(postMethod);// 打印服务器返回的状态logger.info("服务器返回的状态=" + postMethod.getStatusLine());// 打印结果页面String response = new String(postMethod.getResponseBodyAsString().getBytes("gb2312"));// 打印返回的信息logger.info("返回的信息=" + response);// 释放连接postMethod.releaseConnection();}
