使用java获取网络响应内容--Get请求方式

使用java获取网络内容--Get请求方式

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.entity.ContentType;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.protocol.BasicHttpContext;
import org.apache.http.util.EntityUtils;

public class HttpUtils {

    /**
     *  @Method: 获取浏览器访问内容--get请求
     *  @Result: 浏览器响应内容
     */
    public String GetHttpResponseBody(String URLStr){
        HttpClient httpClient = new DefaultHttpClient();
        BasicHttpContext httpContext = new BasicHttpContext();
        HttpGet httpGet = new HttpGet(URLStr);
        try {
            //将HttpContext对象作为参数传给execute()方法,则HttpClient会把请求响应交互过程中的状态信息存储在HttpContext中
            HttpResponse response = httpClient.execute(httpGet, (org.apache.http.protocol.HttpContext) httpContext);
            org.apache.http.HttpEntity entity = response.getEntity();
            if(null != entity){
                String httpResponseBody = EntityUtils.toString(entity, ContentType.getOrDefault(entity).getCharset());
                if(httpResponseBody!=null) {
                    return httpResponseBody;
                }
                EntityUtils.consume(entity);
            }
        } catch (Exception e) {
            return e.getLocalizedMessage();
        }finally{
            httpClient.getConnectionManager().shutdown();
        }
        return null;
    }
