HttpClient发送Post，Get请求demo

一.Get请求

    /**
     * 通过httpclient到指定的uri来get数据
     */
    public static String getData(String url){    
        HttpClient httpClient = new HttpClient();
        //设置代理
        httpClient.getHostConfiguration().setProxy(Config.getProxyHost(), Config.getProxyPort());
        GetMethod getMethod = new GetMethod(url); //get指定url的数据
        try {
            int status = httpClient.executeMethod(getMethod);
            if (status == HttpStatus.SC_OK) {  //请求url后，服务器返回的执行状态
                return getMethod.getResponseBodyAsString();
            }else{
                return null;
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

二.Post请求

    /**
     * 通过httpclient send数据到指定的url【无参数类型】
     */
    @SuppressWarnings("deprecation")
    public static String sendData(String url, String content){    
        HttpClient httpClient = new HttpClient();
        //设置代理
        httpClient.getHostConfiguration().setProxy(Config.getProxyHost(), Config.getProxyPort());
        //post数据到该url
        PostMethod postMethod = new PostMethod(url);  
        //设置参数编码为gbk
        postMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET,"gbk");    
            
        // 无参数类型，把内容放入postMethod中
        postMethod.setRequestBody(content);        
        
        try {
            //执行
            int status = httpClient.executeMethod(postMethod);
            return postMethod.getResponseBodyAsString();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    /**
     * 通过httpclient send数据到指定的url【含参数类型】
     */
    @SuppressWarnings("deprecation")
    public static String sendData(String url){    
        HttpClient httpClient = new HttpClient();
        //设置代理
        httpClient.getHostConfiguration().setProxy(Config.getProxyHost(), Config.getProxyPort());
        //post数据到该url
        PostMethod postMethod = new PostMethod(url);  
        //设置参数编码为gbk
        postMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET,"gbk");
        
        //有参数类型，需要设置构造键值对参数
        NameValuePair[] data = { new NameValuePair("id", "10"), 
        new NameValuePair("name", "Helen") }; 
        // 把参数值放入postMethod中 
        postMethod.setRequestBody(data);     
           
        try {
            //执行
            int status = httpClient.executeMethod(postMethod);
            return postMethod.getResponseBodyAsString();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
