studio添加的依赖
android {
useLibrary ‘org.apache.http.legacy’
}
post的方法
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(“http://cnivi.com.cn/login”);
post.setEntity(reqEntity);
post.setConfig(requestConfig);
HttpResponse response = client.execute(post);

    if (response.getStatusLine().getStatusCode() == 200) {  
        HttpEntity resEntity = response.getEntity();  
        String message = EntityUtils.toString(resEntity, "utf-8");  
        System.out.println(message);  
    } else {  
        System.out.println("请求失败");  
    }  

get方法
首先需要先创建一个DefaultHttpClient的实例

HttpClient httpClient=new DefaultHttpClient();
先创建一个HttpGet对象,传入目标的网络地址,然后调用HttpClient的execute()方法即可:

HttpGet HttpGet=new HttpGet(“http://www.baidu.com”);

httpClient.execute(httpGet);

If(httpResponse.getStatusLine().getStatusCode()==200){
//请求和响应都成功了
HttpEntityentity=HttpResponse.getEntity();//调用getEntity()方法获取到一个HttpEntity实例
Stringresponse=EntityUtils.toString(entity,”utf-8”);//用EntityUtils.toString()这个静态方法将HttpEntity转换成字符串,防止服务器返回的数据带有中文,所以在转换的时候将字符集指定成utf-8就可以了
}
