  • 【转】HttpClient使用Post和Get提交参数

    package httpclient;
    
    import java.io.IOException;
    import java.net.URLEncoder;
    
    import org.apache.commons.httpclient.HttpClient;
    import org.apache.commons.httpclient.HttpMethod;
    import org.apache.commons.httpclient.NameValuePair;
    import org.apache.commons.httpclient.methods.GetMethod;
    import org.apache.commons.httpclient.methods.PostMethod;
    
    public class HttpClientTest {
    
    	public static void main(String[] args) throws Exception{
    		String url = "/webservices/DomesticAirline.asmx/getDomesticAirlinesTime";
    		String host = "www.webxml.com.cn";
    		String param = "startCity="+URLEncoder.encode("杭州", "utf-8")+"&lastCity=&theDate=&userID=";
    		HttpClient httpClient = new HttpClient();
    		httpClient.getHostConfiguration().setHost(host, 80, "http");		
    		
    		HttpMethod method = getMethod(url, param);
    		//HttpMethod method = postMethod(url);
    		
    		httpClient.executeMethod(method);
    		
    		String response = method.getResponseBodyAsString();
    		//String response = new String(method.getResponseBodyAsString().getBytes("ISO-8859-1"));				
    		System.out.println(response);
    	}
    	
    	private static HttpMethod getMethod(String url,String param) throws IOException{
    		GetMethod get = new GetMethod(url+"?"+param);
    		get.releaseConnection();
    		return get;
    	}
    		
    	private static HttpMethod postMethod(String url) throws IOException{ 
    		PostMethod post = new PostMethod(url);
    		post.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=gbk");  
    		NameValuePair[] param = { new NameValuePair("startCity","杭州"),
    				new NameValuePair("lastCity","沈阳"),
    				new NameValuePair("userID",""),
    				new NameValuePair("theDate","")	} ;
        	post.setRequestBody(param);
        	post.releaseConnection();
    		return post;
    	}
    }
    

     
    如果PostMethod提交的是中文字符,需要加上相应的编码格式:  post.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=gbk");  
    如果GetMethod提交的参数有中文字符,需要先转换成utf-8格式:  URLEncoder.encode("杭州", "utf-8");
