httpclient的post方式请求，收不到请求数据

Question

HttpClient client = new HttpClient();
PostMethod post = new PostMethod(url);
post.setRequestHeader("content-type", "application/x-www-form-urlencoded");
NameValuePair[] pare = new NameValuePair[]{new NameValuePair("class","FtpAgereementInfoCache")};
post.setRequestBody(pare);
client.executeMethod(post);

在另请求的jsp中用String[] className = request.getParameterValues("class");获取数据得到的是null，
不过有些门户可以收到，有些门户收不到。为什么？？？？

Answer 1

请求数据时你试试这个方法
StringEntity reqEntity = new StringEntity("class=FtpAgereementInfoCache");
// 设置类型

reqEntity.setContentType("application/x-www-form-urlencoded");

// 设置请求的数据

postMethod.setEntity(reqEntity);

//执行请求
httpclient.execute(postMethod);
