HttpClient、CloseableHttpClient请求接口

HttpClient Get方式请求接口

    public JSONObject getProducts(String token) {
        JSONObject jsonObject = null;
        //创建HttpClient对象
        HttpClient objClient = new HttpClient();
		
		//设置传递的编码格式，防止出现乱码错误
        objClient.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
		
		//创建GetMethod 对象，参数为请求的地址
        GetMethod method = new GetMethod("https://XXXXX.com/");
        
        //设置请求头
        method.setRequestHeader("token", token);

        try {
        	//执行方法请求接口
            objClient.executeMethod(method);
            //打印服务器返回的状态
            System.out.println(method.getStatusLine());
            //获取返回值信息
            String strResponseBody = new String(method.getResponseBody(),"UTF-8");
            System.out.println(strResponseBody);
            jsonObject = JSONObject.parseObject(strResponseBody);
        } catch (IOException e) {
            e.printStackTrace();
        }
        //释放连接
        method.releaseConnection();
        return jsonObject;
    }

HttpClient Post方式请求接口

    public JSONObject getProducts(String token) {
        JSONObject jsonObject = null;
        //创建HttpClient对象
        HttpClient objClient = new HttpClient();
		
		//设置传递的编码格式，防止出现乱码错误
        objClient.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
		
		//创建PostMethod 对象，参数为请求的地址
        PostMethod method = new PostMethod("https://XXXXX.com/");
        
        //设置请求头
        method.setRequestHeader("token", token);

CloseableHttpClient Get方式请求接口

        //设置请求头
       method.setHeader("token", token);

        try {
        	//执行方法请求接口得到响应
        	HttpResponse response = httpclient.execute(method);

            String content = EntityUtils.toString(response.getEntity(), "UTF-8");
            //转为json格式
            jsonObject = JSON.parseObject(content);
            System.out.println(jsonObject.toString());

CloseableHttpClient Post方式请求接口
