httpclient几种请求方式

一、httpclient 模拟get请求，并获取cookie信息

public class MyCookiesForGet {

    private String url;
    //用来读取.properties的配置文件
    private ResourceBundle bundle;
    private CookieStore store;
    @BeforeTest
    public void beforeTest() {
        //读取加载.properties的配置文件
        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;

        //HttpGet 相当于在浏览器地址栏输入一个地址
        HttpGet get = new HttpGet(testUrl);
        //DefaultHttpClient 相当于一个浏览器，先new一个浏览器
        DefaultHttpClient client = new DefaultHttpClient();

        //client.execute(get) 相当于用浏览器打开网页了，获得一个response结果
        HttpResponse response = client.execute(get);

        //response.getEntity() 打印请求的实体内容 返回json格式
        //EntityUtils.toString() 将json格式实体内容转换成字符串String
        result = EntityUtils.toString(response.getEntity(),"utf-8");

        System.out.println(result);

        //获取cookies信息
        this.store = client.getCookieStore();
        List<Cookie> cookieList = this.store.getCookies();

        for (Cookie cookie : cookieList) {
            String name = cookie.getName();
            String value = cookie.getValue();
            System.out.println("cookie name = "+name+",cookie value = "+value);
        }

    }
}

二、httpclient 模拟携带cookie信息进行的get请求

public class MyCookiesForGet {

    private String url;
    //用来读取.properties的配置文件
    private ResourceBundle bundle;
    private CookieStore store;
    @BeforeTest
    public void beforeTest() {
        //读取加载.properties的配置文件
        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;

        //HttpGet 相当于在浏览器地址栏输入一个地址
        HttpGet get = new HttpGet(testUrl);
        //DefaultHttpClient 相当于一个浏览器，先new一个浏览器
        DefaultHttpClient client = new DefaultHttpClient();

        //client.execute(get) 相当于用浏览器打开网页了，获得一个response结果
        HttpResponse response = client.execute(get);

        //response.getEntity() 打印请求的实体内容 返回json格式
        //EntityUtils.toString() 将json格式实体内容转换成字符串String
        result = EntityUtils.toString(response.getEntity(),"utf-8");

        System.out.println(result);

        //获取cookies信息
        this.store = client.getCookieStore();
        List<Cookie> cookieList = this.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 {
        //测试url拼接，使用ResourceBundle bundle 来读取.properties文件配置内容
        String uri = bundle.getString("test.get.with.cookies");
        String testUrl = this.url + uri;

        //HttpGet 相当于在浏览器中输入url
        HttpGet get = new HttpGet(testUrl);

        //DefaultHttpClient 相当于创建打开一个浏览器
        DefaultHttpClient client = new DefaultHttpClient();

        //设置cookies信息
        client.setCookieStore(this.store);

        //HttpResponse 相当于浏览器打开网页，并或得了响应结果
        HttpResponse response = client.execute(get);

        //获取响应状态码
        int statusCode = response.getStatusLine().getStatusCode();
        System.out.println("statusCode = "+statusCode);

        if(statusCode == 200) {
            //获取响应格式为json的实体内容，并转换为字符串
            String result = EntityUtils.toString(response.getEntity(),"utf-8");
            System.out.println(result);
        }
    }
}

三、httpclient模拟携带cookie信息的post请求（请求格式为json）

public class MyCookiesForPost {
    private String url;
    //用来读取.properties的配置文件
    private ResourceBundle bundle;
    private CookieStore store;
    @BeforeTest
    public void beforeTest() {
        //读取加载.properties的配置文件
        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;

        //HttpGet 相当于在浏览器地址栏输入一个地址
        HttpGet get = new HttpGet(testUrl);
        //DefaultHttpClient 相当于一个浏览器，先new一个浏览器
        DefaultHttpClient client = new DefaultHttpClient();

        //client.execute(get) 相当于用浏览器打开网页了，获得一个response结果
        HttpResponse response = client.execute(get);

        //response.getEntity() 打印请求的实体内容 返回json格式
        //EntityUtils.toString() 将json格式实体内容转换成字符串String
        result = EntityUtils.toString(response.getEntity(),"utf-8");

        System.out.println(result);

        //获取cookies信息
        this.store = client.getCookieStore();
        List<Cookie> cookieList = this.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;相当于打开一个浏览器
        DefaultHttpClient client = new DefaultHttpClient();
        //声明一个方法，这个方法就是post方法;相当于在浏览器中输入一个请求地址
        HttpPost post = new HttpPost(testUrl);
        //添加参数(json格式类型的请求参数)
        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,将参数绑定到请求信息中
        StringEntity entity = new StringEntity(param.toString(),"utf-8");
        post.setEntity(entity);
        //声明一个对象用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，判断返回结果是否符合预期
        //将返回的响应结果字符串转换成json对象
        JSONObject resultJson = new JSONObject(result);
        //判断具体的返回结果值
        String success = (String) resultJson.get("huhansan");
        String status = (String) resultJson.get("status");
        Assert.assertEquals("success",success);
        Assert.assertEquals("1",status);

    }
}

四、httpclient模拟携带cookie信息的post请求（请求格式为表单）

public class MyCookiesForPost {
    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("wms.login.url");
    }

    @Test
    public void testGetCookies() throws IOException {
        String result;
        String uri = bundle.getString("wms.login.uri");
        String testUrl = this.url + uri;

        //测试逻辑代码编写
        HttpGet get = new HttpGet(testUrl);
        DefaultHttpClient client = new DefaultHttpClient();
        HttpResponse response = client.execute(get);
        System.out.println(response);
        result = EntityUtils.toString(response.getEntity(),"utf-8");
        //System.out.println(result);

        //获取cookies信息
        this.store = client.getCookieStore();
        List<Cookie> cookieList = this.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("wms.login.validate");
        //拼接最终测试地址
        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
        List <NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("username","ldcx"));
        nvps.add(new BasicNameValuePair("password","123456"));
        //设置请求头信息 设置header
        post.setHeader("content-type","application/x-www-form-urlencoded");
        //将参数信息添加到方法中
        HttpEntity entity = new UrlEncodedFormEntity(nvps,"utf-8");
        //StringEntity entity = new StringEntity(nvps.toString(),"utf-8");
        post.setEntity(entity);
        System.out.println("请求url地址"+post.getURI());
        //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请求
        HttpResponse response = client.execute(post);
        //获取响应结果
        result = EntityUtils.toString(response.getEntity(),"utf-8");
        System.out.println(result);

    }
    @Test(dependsOnMethods = {"testPostMethod"})
    public void testGetWareHouse() throws IOException {
        String result;
        String uri = bundle.getString("wms.warehouse");
        String testUrl = this.url + uri;

        //测试逻辑代码编写
        HttpGet get = new HttpGet(testUrl);
        DefaultHttpClient client = new DefaultHttpClient();
        client.setCookieStore(this.store);
        HttpResponse response = client.execute(get);
        System.out.println(response);
        result = EntityUtils.toString(response.getEntity(),"utf-8");
        System.out.println(result);
    }
}
