//不传参数
public String clientPost(String url){
String result = null;
try {
HttpClient client = new HttpClient();
client.getHostConfiguration().setProxy("127.0.0.1", 8080);
HttpMethod method = new PostMethod("http:www.baidu.com");
client.executeMethod(method);
result = method.getResponseBodyAsString();
// 释放连接
method.releaseConnection();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}

//不传参数
public String clientPostPara(String url,String json){
//封装参数
NameValuePair[] data = {new NameValuePair("json" ,json)};
url ="http:www.baidu.com";
//访问路径
PostMethod postMethod = new PostMethod(url);
//加入参数
postMethod.setRequestBody(data);
String result=null;
int statusCode;
try {
HttpClient httpClient = new HttpClient();
statusCode = httpClient.executeMethod(postMethod);
if (statusCode == 200) {
result = postMethod.getResponseBodyAsString();
}
System.out.println(new String(Base64.decodeBase64(result.getBytes())));
// 释放连接
postMethod.releaseConnection();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
