import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;

// HTTP GET request
public static String SendGet(String url) {
    HttpClient client = new HttpClient();
    GetMethod method = new GetMethod(url);
    
    try {
        int statusCode = client.executeMethod(method);

        if (statusCode != HttpStatus.SC_OK) {
            logger.error("获取SendGet失败:" + method.getStatusLine());
        }
        
        return method.getResponseBodyAsString();
    } catch (HttpException e) {
        logger.error("获取SendGet失败: Fatal protocol violation", e);
    } catch (IOException e) {
        logger.error("获取SendGet失败: transport error", e);
    } finally {
          method.releaseConnection();
    }
    
    return "";
}

2，post请求

// HTTP POST
public static String SendPOST(String url) {
    HttpClient client = new HttpClient();
    PostMethod method = new PostMethod(url);
    
    try {
        int statusCode = client.executeMethod(method);

        if (statusCode != HttpStatus.SC_OK) {
            logger.error("获取SendPOST失败:" + method.getStatusLine());
        }
        
        return method.getResponseBodyAsString();
    } catch (HttpException e) {
        logger.error("获取SendPOST失败: Fatal protocol violation", e);
    } catch (IOException e) {
        logger.error("获取SendPOST失败: transport error", e);
    } finally {
          method.releaseConnection();
    }
