httpclient 使用方式介绍

第一：Get方式请求

package com.hct;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONObject;

public class GetPort {

	public static JSONObject getUrl(String url) throws ClientProtocolException, IOException {
		 // 创建HttpClient实例
        DefaultHttpClient httpclient = new DefaultHttpClient();
        JSONObject son = new JSONObject();
        // 创建Get方法实例
        HttpGet httpgets = new HttpGet(url);
        HttpResponse response = httpclient.execute(httpgets);
        HttpEntity entity = response.getEntity();
        if (entity != null) {
            InputStream instreams = entity.getContent();
            String str = convertStreamToString(instreams);
            son = new JSONObject(str);
            System.out.println("以下是响应结果:");
            System.out.println(str);
            // Do not need the rest
            httpgets.abort();
        }
        return son;
    }  

    public static String convertStreamToString(InputStream is) {
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();      

        String line = null;
        try {
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                is.close();
            } catch (IOException e) {
               e.printStackTrace();
            }
        }
        return sb.toString();
	}

}

第二：post请求方式

package com.hct;

import java.io.IOException;
import java.util.Map;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import org.json.JSONObject;

public class PostPort {

	public JSONObject postResponse(String url,String json,Map<String, String> headers) throws ClientProtocolException, IOException {
		HttpClient httpclient = new DefaultHttpClient();
		String uri = url;
		HttpPost httppost = new HttpPost(uri);
		if(!headers.isEmpty()){
			for(String key : headers.keySet())
			{
				// 遍历map对象添加http头信息
				httppost.addHeader(key, headers.get(key));
			}
		}
		JSONObject parameters = new JSONObject(json);
		//将参数添加进请求url中
		httppost.setEntity(new StringEntity(parameters.toString()));

		HttpResponse response;
		//执行请求
		response = httpclient.execute(httppost);
		//获取状态码
		int t = response.getStatusLine().getStatusCode();
		if(t==200){
			String rev = EntityUtils.toString(response.getEntity());
			System.out.println(rev);
			parameters =new JSONObject(rev);
		/*	测试使用
			String orderId = (String) parameters.get("orderId");
			System.out.println(orderId);*/

		}
		return parameters;
	}

	public JSONObject postResponse1(String url,String json) throws ClientProtocolException, IOException{
		String uri =url;
		String para = json;
		JSONObject jso = null;
		jso = postResponse(uri, para, null);
		return jso;

	}

}

第三：使用testng进行测试

package com.hct118;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import org.apache.http.client.ClientProtocolException;
import org.json.JSONObject;
import org.testng.Assert;
import org.testng.annotations.Test;

public class TestPortCase {
  //核保接口测试
  @Test
  public void testPost() throws ClientProtocolException, IOException {
		String uri = "http://10.253.10.226:8080/invest/mvc/m/clients/underwriter";
		Map<String, String> map = new HashMap<String, String>();
		map.put("token", "9802525003ff40d1a39863722371f8c1");
		map.put("Content-Type", "application/json");
		String json = "{\"phoneNo\":18234560012,\r\n" +
				"\"tradeAccount\":\"test8887\",\r\n" +
				"\"name\":\"谭宝玲\",\r\n" +
				"\"certNo\":\"440681198610152044\",\r\n" +
				"\"amount\":\"40000.11\",\r\n" +
				"\"channelRequestNo\":\"test00044442\",\r\n" +
				"\"productOffingCode\":\"101001048364\"\r\n" +
				"}";
		PostPort pp = new PostPort();
		JSONObject jso = pp.postResponse(uri, json, map);
		System.out.println(jso.get("channelOrderNo"));
		Assert.assertEquals(jso.get("returnMsg"), "成功");
  }
  @Test
  public void testGet() throws ClientProtocolException, IOException
  {
	  String url = "http://10.253.10.226:8080/invest/mvc/commons/sms/otp/new?phoneNo=18234560012&token=9802525003ff40d1a39863722371f8c1";
	  JSONObject js =  GetPort.getUrl(url);
	  Assert.assertEquals(js.get("status"), "SUCCESS");
  }

}
