【四:httpclient的使用】

目录

1、Demo案例

json 复制代码
public class MyHttpClient {
    @Test
    public 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

java 复制代码
public class MyCookiesForGet {

    private String url;
    private ResourceBundle bundle;
    //用来存储cookies信息的变量
    private CookieStore store;
    @BeforeTest
    public void beforeTest(){
        bundle = ResourceBundle.getBundle("application", Locale.CHINA);
        url = bundle.getString("test.url");
    }

    @Test
    public void testGetCookies() throws IOException {

        String result;
        //       从配置文件中 拼接测试的url
        String 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

java 复制代码
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
    @BeforeTest
    public void beforeTest(){
        bundle = ResourceBundle.getBundle("application", Locale.CHINA);
        url = bundle.getString("test.url");
    }

    @Test
    public void testGetCookies() throws IOException {

        String result;
//       从配置文件中 拼接测试的url
        String 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header
        post.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

java 复制代码
test.url=http://localhost:8899
dev.url=http://localhost:8899

getCookies.uri=/getCookies
test.get.with.cookies=/get/with/cookies
test.post.with.cookies=/post/with/cookies
login=/login
