HttpClient通过HttpPost传递参数，Connection reset by peer: socket write error

原文链接：HttpClient通过HttpPost传递参数

 

发起客户端请求，直接请求路径url后带大量参数报错：Connection reset by peer: socket write error

解决方法：把参数放到请求体中。

 

HttpClient新版本（新老版本没有做明确界定，Sorry!） 

package http;

import java.util.ArrayList;
import java.util.List;

import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

public class HttpTests {

    /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost("******/abc");
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("username", "vip"));
        nvps.add(new BasicNameValuePair("password", "secret"));
        httpPost.setEntity(new UrlEncodedFormEntity(nvps));
        httpclient.execute(httpPost);
        httpclient.getConnectionManager().shutdown();
    }

}

HttpClient 老版本： 

package http;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;

public class HttpTests {

    /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        HttpClient httpclient = new HttpClient();
        PostMethod httpPost =new PostMethod("******/abc");
        NameValuePair[] param = { new NameValuePair("username", "vip")};
        httpPost.setRequestBody(param);
        httpclient.executeMethod(httpPost);
    }

}
