HttpClient方式調用接口的實例

　　使用HttpClient的方式調用接口的實例。

 

public class TestHttpClient {

    public static void main(String[] args) {
        // 請求接口地址
        String url = "";
        // 請求參數
        String userid = "";

        HttpClient httpclient = null;
        PostMethod post = null;
        try {
            //創建連接
            httpclient = new HttpClient();
            post = new PostMethod(url);
            // 設置編碼方式
            post.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
            // 添加參數
            post.addParameter("userid", userid);
            // 執行請求
            httpclient.executeMethod(post);
            // 接口返回信息
            String info = new String(post.getResponseBody(), "UTF-8");
            System.out.println(info);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 關閉連接，釋放資源
            post.releaseConnection();
            ((SimpleHttpConnectionManager) httpclient.getHttpConnectionManager()).shutdown();
        }
    }
}
