使用HttpClient实现接口测试

使用HttpClient4.2.5做了一个简单的接口测试的实验，记录下来以后参考。

package cn.test;import java.io.IOException;import org.apache.http.HttpResponse;import org.apache.http.HttpStatus;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.HttpClient;import org.apache.http.client.methods.HttpGet;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.util.EntityUtils;import org.json.JSONArray;import org.json.JSONException;import org.json.JSONObject;import org.testng.Assert;import org.testng.annotations.AfterClass;import org.testng.annotations.BeforeClass;import org.testng.annotations.Parameters;import org.testng.annotations.Test;public class MobileLibInterfaceTest {private static final int SUCCESS_CODE = 1;private static final String PRODUCT_ID = "326610";private static final String PRODUCT_NAME = "三星 GALAXY Note II N7100（16GB）";//初始化httpClientHttpClient httpClient = new DefaultHttpClient();@BeforeClasspublic void beforeClass() {}@Parameters({"URL"})@Test public void productInfo(String URL) throws ClientProtocolException, IOException, JSONException {//获取httpGetHttpGet httpGet = new HttpGet(URL);//执行get请求HttpResponse response = httpClient.execute(httpGet);//判断服务器响应的状态码System.out.println(response.getStatusLine().getStatusCode());Assert.assertEquals(HttpStatus.SC_OK, response.getStatusLine().getStatusCode(),"状态码不是200，请求没成功");//读取返回数据String entity = EntityUtils.toString(response.getEntity());//返回的数据类型为json，使用org.json jar包来解析JSONObject json = new JSONObject(entity);System.out.println(json.get("code"));Assert.assertEquals(SUCCESS_CODE, json.get("code"),"返回的code不为1，请求失败");//返回的结果中，data为数组，将其转换为list，获取指定key的值JSONArray array = json.getJSONArray("data");for(int i=0; i<array.length(); i++) {JSONObject data = array.getJSONObject(i);String phoneID = data.getString("id");Assert.assertEquals(phoneID, PRODUCT_ID, "返回的产品 型号ID不一致");String phoneName = data.getString("name");Assert.assertEquals(phoneName, PRODUCT_NAME, "返回的产品名称不一致");System.out.println(phoneID+", "+phoneName);}}@AfterClasspublic void afterClass() {//断开连接httpClient.getConnectionManager().shutdown();}}

请求成功后，页面返回的是的json格式的数据

{"code":1,"data":[{"id":"326610","name":"\u4e09\u661f GALAXY Note II N7100\uff0816GB\uff09","picture":"http:\/\/y1.ifengimg.com\/iproduct\/p1\/pics_big\/240\/ceK6fPqR05Yp6_top.jpg","marketPrice":"4699","score":"9","marketTime":"1349020800","mobileStyle":"3G\u624b\u673a\uff0c\u667a\u80fd\u624b\u673a\uff0c\u62cd\u7167\u624b\u673a\uff0c4G\u624b\u673a\uff0c\u5e73\u677f\u624b\u673a","screenSize":"5.500","isTouchScreen":"\u7535\u5bb9\u5c4f\uff0c\u591a\u70b9\u89e6\u63a7","screeType":"HD Super AMOLED","screeLong":"1280x720\u50cf\u7d20","networkType":"\u5355\u5361\u591a\u6a21","GSM":"GSM\uff0cWCDMA\uff0cLTE","dataService":"GPRS\uff0cEDGE\uff0cHSPA","supportfrequency":"2G\uff1aGSM 850\/900\/1800\/1900\r\n3G\uff1aWCDMA 850\/900\/1900\/2100","KeyboardType":"\u865a\u62dfQWERTY\u952e\u76d8","color":"\u4e91\u77f3\u767d\u8272\uff0c\u949b\u91d1\u7070\u8272\uff0c\u94bb\u77f3\u7c89\u8272","long":"151.1x80.5x9.4mm","weight":"180g"}],"msg":null}

最后需要解析json的数据，参考了下面这两篇文章：

接口名称

手机对比

接口示例

http://digi.tech.ifeng.com/mobile/compare/api?ids=id1_id2_id3

接口描述

使用手机id进行参数对比

接口协议

HTTP[POST]

参数说明

ids

要对比的手机id序列，用下划线_分隔

必填

返回值约定(json格式)

注册失败时，显示相应的失败信息

成功时：{"code":1,"message":"\u64cd\u4f5c\u6210\u529f","data":["id1":{“name”:”iphone5”,”price”:4570,”pic”: “http://y1.ifengimg.com/iproduct/p1/top/pics/753/ceLBceL0LElec_top.jpg ”},“id2”:{“name”: “iphone5”, “price”:4570, “pic”: “http://y1.ifengimg.com/iproduct/p1/top/pics/753/ceLBceL0LElec_top.jpg ”},“id3”:{“name”: “iphone5”, “price”:4570, “pic”: “http://y1.ifengimg.com/iproduct/p1/top/pics/753/ceLBceL0LElec_top.jpg”}]}

备注

返回数据说明

code：接口调用结果 0-失败 1-成功

message：错误信息

data：手机信息数组  包括手机id和多个属性
