【四：httpclient的使用】

1、Demo案例

public class MyHttpClient {@Testpublic void test1() throws IOException {//用来存放我们的结果String result;HttpGet get = new HttpGet("http://www.baidu.com");//这个是用来执行get方法的HttpClient client = new DefaultHttpClient();HttpResponse response = client.execute(get);result = EntityUtils.toString(response.getEntity(),"utf-8");System.out.println(result);}
}

2、请求一个带cookies的get请求

需要结合mock服务

public class MyCookiesForGet {private String url;private ResourceBundle bundle;//用来存储cookies信息的变量private CookieStore store;@BeforeTestpublic void beforeTest(){bundle = ResourceBundle.getBundle("application", Locale.CHINA);url = bundle.getString("test.url");}@Testpublic void testGetCookies() throws IOException {String result;//       从配置文件中 拼接测试的urlString uri = bundle.getString("getCookies.uri");String testUrl = this.url+uri;//        测试逻辑代码书写HttpGet get = new HttpGet(testUrl);DefaultHttpClient client = new DefaultHttpClient();HttpResponse response = client.execute(get);result = EntityUtils.toString(response.getEntity(),"utf-8");System.out.println(result);//获取cookies信息this.store = client.getCookieStore();List<Cookie> cookieList = store.getCookies();for (Cookie cookie : cookieList){String name = cookie.getName();String value = cookie.getValue();System.out.println("cookie name = " + name+ ";  cookie value = " + value);}}@Test(dependsOnMethods = {"testGetCookies"})public void testGetWithCookies() throws IOException {String uri = bundle.getString("test.get.with.cookies");String testUrl = this.url+uri;HttpGet get = new HttpGet(testUrl);DefaultHttpClient client = new DefaultHttpClient();//设置cookies信息client.setCookieStore(this.store);HttpResponse response = client.execute(get);//获取响应的状态码int statusCode = response.getStatusLine().getStatusCode();System.out.println("statusCode = " + statusCode);if(statusCode == 200){String result = EntityUtils.toString(response.getEntity(),"utf-8");System.out.println(result);}}
}

3、请求一个带cookies的post请求

需要结合mock服务

public class MyCookiesForPost {private String url;  //定义成全局变量private ResourceBundle bundle;//设置成全局变量//用来存储cookies信息的变量private CookieStore store; //定义成全局变量@BeforeTestpublic void beforeTest(){bundle = ResourceBundle.getBundle("application", Locale.CHINA);url = bundle.getString("test.url");}@Testpublic void testGetCookies() throws IOException {String result;
//       从配置文件中 拼接测试的urlString uri = bundle.getString("getCookies.uri");String testUrl = this.url+uri;//        测试逻辑代码书写HttpGet get = new HttpGet(testUrl);DefaultHttpClient client = new DefaultHttpClient();HttpResponse response = client.execute(get);result = EntityUtils.toString(response.getEntity(),"utf-8");System.out.println(result);//获取cookies信息this.store = client.getCookieStore();List<Cookie> cookieList = store.getCookies();for (Cookie cookie : cookieList){String name = cookie.getName();String value = cookie.getValue();System.out.println("cookie name = " + name+ ";  cookie value = " + value);}}@Test(dependsOnMethods = {"testGetCookies"})public void testPostMethod() throws IOException {String uri = bundle.getString("test.post.with.cookies");//拼接最终的测试地址String testUrl = this.url + uri;//声明一个Client对象，用来进行方法的执行DefaultHttpClient client = new DefaultHttpClient();//声明一个方法，这个方法就是post方法HttpPost post = new HttpPost(testUrl);//添加参数JSONObject param = new JSONObject();param.put("name","huhansan");param.put("age","18");//设置请求头信息 设置headerpost.setHeader("content-type","application/json");//将参数信息添加到方法中StringEntity entity = new StringEntity(param.toString(),"utf-8");post.setEntity(entity);//声明一个对象来进行响应结果的存储String result;//设置cookies信息client.setCookieStore(this.store);//执行post方法HttpResponse response = client.execute(post);//获取响应结果result = EntityUtils.toString(response.getEntity(),"utf-8");System.out.println(result);//处理结果，就是判断返回结果是否符合预期//将返回的响应结果字符串转化成为json对象JSONObject resultJson = new JSONObject(result);//获取到结果值String success = (String) resultJson.get("huhansan");String status = (String) resultJson.get("status");//具体的判断返回结果的值Assert.assertEquals("success",success);Assert.assertEquals("1",status);}}

案例一，案例二的properties的配置

test.url=http://localhost:8899
dev.url=http://localhost:8899getCookies.uri=/getCookies
test.get.with.cookies=/get/with/cookies
test.post.with.cookies=/post/with/cookies
login=/login
