HttpClient

看了几天的HttpClient，写了一点代码，留到以后用。

使用的是common-httpclient.jar

public void SendHttpRequest(){
        PostMethod method=null;
        String url="http://localhost:8080/com.isoftstone.iics.bizsupport.epps/epolicy/create";
        String xmlString="";
        method=new PostMethod(url);
        client.getParams().setContentCharset("utf-8");
        try
        {
            client.getHttpConnectionManager().getParams().setConnectionTimeout(6000);
            RequestEntity entity=new StringRequestEntity(xmlString,"text/xml","utf-8");
            method.setRequestEntity(entity);
            client.executeMethod(method);
            String response=method.getResponseBodyAsString();
            System.out.println(response+"------");
            method.releaseConnection();
        } catch (Exception e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
//        RequestEntity entity = new StringRequestEntity(xmlString, "text/xml", encoding);
    }
    public void SendBaidu(){
        //创建HttpClient实例
        /*HttpClientParams params=new HttpClientParams();
        params.setConnectionManagerTimeout(6000);
        params.setContentCharset("utf-8");
        HttpClient client=new HttpClient(params);*/
        HttpClient client=new HttpClient();

        method.getParams().setContentCharset(charset);

        }

        int statu=0;
        try

        }

    }

HttpClient就先看到这把！
