SpringBoot使用HttpClient远程调用

Posted 2021-02-06 我爱si搬砖

一.　　Get请求

try {
            //拼接url
            url = url+"access_token="+token+"&department_id=1&fetch_child=1";
            //解决证书明匹配问题
            SSLSocketFactory.getSocketFactory().setHostnameVerifier(new     
                    AllowAllHostnameVerifier());
            //根据地址获取请求
            HttpGet request = new HttpGet(url);
            //获取当前客户端对象
            HttpClient httpClient = new DefaultHttpClient();
            //通过请求获取相应对象
            HttpResponse response = httpClient.execute(request);
            // 判断网络连接状态码是否正常(0--200都数正常)
            String result=null;
            if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                result= EntityUtils.toString(response.getEntity(),"utf-8");
            }    

} catch (Exception e) {
       e.printStackTrace();
 }                           

 

二.　　Post请求

 try{
        String url = userMapper.getValue(urlId);
        url = url + "access_token=" + token;
        //主机证书明不匹配问题
        SSLSocketFactory.getSocketFactory().setHostnameVerifier(new AllowAllHostnameVerifier());

　　　　 //获取请求地址
        HttpPost post = new HttpPost(url);
　　　　 //获取当前客户端对象
        HttpClient httpClient = new DefaultHttpClient();

        // 设置超时时间
        httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 2000);
        httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 2000);
　　　　　//设置参数
        StringEntity s = new StringEntity(jsonObject.toString());
        s.setContentEncoding("UTF-8");
        s.setContentType("application/json");
        post.setEntity(s);
　　　　　//通过请求获得相应的对象　　　
        HttpResponse res = client.execute(post);
　　　　 //判断是否成功

　　　　 if(res.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
    　　　　HttpEntity entity = res.getEntity();
    　　　　String result = EntityUtils.toString(res.getEntity());// 返回json格式：
　　　　}

} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
