httpClient post请求并传送form-data数据

public static void main(String[] args) {
        String urle="http://192.168.1.107:12811/oauth/check_token";
        String token="RlNzMtODRmNC0yMTGrBQVIBhh435qCYveTOQV6OQwyyCnADUIKQn_yQ";
        String s = doPost( urle, token );
        System.out.println(s);
    }
    
    public static String doPost(String url,String token){
        HttpClient client = new HttpClient();
        client.getHttpConnectionManager().getParams().setConnectionTimeout(3000);
        client.getHttpConnectionManager().getParams().setSoTimeout(3000);
        PostMethod method = new UPostMethod(url);//UPostMethod继承PostMethod，见下所示
        String result = "";
        try {
            method.addParameter("token",token);
            client.executeMethod(method);
            byte[] response = method.getResponseBody();
            result = new String(response,"UTF-8");//返回值解析时用的编码格式
        } catch (Exception e) {
            throw new RuntimeException("创建连接失败" + e);
        }finally{
            method.releaseConnection();
        }

        return result;
    }

设置发送参数的编码格式

package com.bfdb.untils;

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

public class UPostMethod extends PostMethod {
    public UPostMethod(String url){
        super(url);
    }
    @Override
    public String getRequestCharSet(){
        return "UTF-8";//设置发送参数的编码格式
    }
}
