## GetMethod ##

1.  简单的一个Test

package com.etc.task;
    
    import net.sf.json.JSONObject;
    import org.apache.commons.httpclient.HttpClient;
    import org.apache.commons.httpclient.methods.GetMethod;
    import org.apache.commons.httpclient.methods.PostMethod;
    
    import java.io.IOException;
    import java.net.URLEncoder;
    
    public class Test { 
        public static void getG(){ 
            //1.创建 HttpClient
            HttpClient client = new HttpClient();
            String s = null;
            try { 
                //中文转码
                s = URLEncoder.encode("A有限公司", "UTF-8");
                //2.构造GetMethod的实例
                GetMethod getMethod = new GetMethod("http://192.xxx.xxx.xx:8088/GetBlist.query_blist_info?customer_name="+s);
                
                getMethod.addRequestHeader("Content-Type", "text/html; charset=UTF-8");
                int i = client.executeMethod(getMethod);
                
                //getMethod.getResponseBodyAsString()获取返回的json
                System.out.println(i+","+getMethod.getResponseBodyAsString());
                
                JSONObject jsonObject = JSONObject.fromObject(getMethod.getResponseBodyAsString());
                String data = jsonObject.getString("data");
                JSONObject jsonData = JSONObject.fromObject(data.substring(1,data.length()-1));
                String cstFlag = jsonData.getString("cst_flag");
                System.out.println("cst_flag="+cstFlag);
            } catch (IOException e) { 
                e.printStackTrace();
            }
        }
    
        public static void main(String[] args){ 
            getG();
        }
    }

## PostMethod ##

1.  一个简单的Test例子

package com.etc.task;
    
    import net.sf.json.JSONObject;
    import org.apache.commons.httpclient.HttpClient;
    import org.apache.commons.httpclient.methods.GetMethod;
    import org.apache.commons.httpclient.methods.PostMethod;
    
    import java.io.IOException;
    import java.net.URLEncoder;
    
    public class Test { 
        public static void getP(){ 
        
        	//1.创建 HttpClient
            HttpClient client = new HttpClient();
            
            String url = "192.168.xxx.xx:8080/xxx"
            //2.构造PostMethod 的实例
            PostMethod postMethod = new PostMethod(url);
            
            postMethod.addRequestHeader("Content-Type", "application/x-www-urlencoded; charset=UTF-8");
            
            //3.请求参数,方式一(简单)
            postMethod.addParameter("customer_name","xxxxx");
            /* //请求参数方式二 NameValuePair[] data = { new NameValuePair("customer_name","xxxx"), new NameValuePair("customer_name2","yyy") }; postMethod.setRequestBody(data); */
            
            try { 
                int i = client.executeMethod(postMethod);
                System.out.println(i+","+postMethod.getResponseBodyAsString());
            } catch (IOException e) { 
                e.printStackTrace();
            }
        }
        public static void main(String[] args){ 
            getP();
        }
    }
