Android:HttpGet与HttpPost的相关文章

Android中使用HttpGet和HttpPost访问HTTP资源

需求:用户登录(name:用户名,pwd:密码) (一)HttpGet :doGet()方法//doGet():将参数的键值对附加在url后面来传递 [java] view plaincopy public String getResultForHttpGet(String name,String pwd) throws ClientProtocolException, IOException{ //服务器  :服务器项目  :servlet名称 String path="http://192.

HTTPClient模块的HttpGet和HttpPost

无论是使用HttpGet,还是使用HttpPost,都必须通过如下3步来访问HTTP资源. 1.创建HttpGet或HttpPost对象,将要请求的URL通过构造方法传入HttpGet或HttpPost对象. 2.使用DefaultHttpClient类的execute方法发送HTTP GET或HTTP POST请求,并返回HttpResponse对象. 3.通过HttpResponse接口的getEntity方法返回响应信息,并进行相应的处理. 如果使用HttpPost方法提交HTTP POS

java最简单的方式实现httpget和httppost请求

java实现httpget和httppost请求的方式多种多样,个人总结了一种最简单的方式,仅仅需几行代码,就能够完美的实现. 此处须要用到两个jar包,httpclient-4.3.1.jar.httpcore-4.3.jar,各位能够到网上自己下载,或者到我的附件里下载,以下先贴上httpget请求的代码: String url = ""; HttpGet request = new HttpGet(url); try { HttpResponse response = HttpC

原文链接:浅谈HTTP-GET . HTTP-POST 和SOAP 1.HTTP-GET 和 HTTP-POST HTTP-GET和HTTP-POST是标准协议,他们使用HTTP(超文本传输协议)谓词(谓词是指条件表达式的求值返回真或假的过程.)对参数金星编码并将参数作为名称/值对传递,还使用关联的请求语义.每个协议都包含一系列HTTP请求标头,HTTP请求标头及其他一些信息定义客户端向服务器请求哪些内容,哪个服务器用一系列HTTP响应标头和所请求的数据进行响应. HTTP-GET 使用 MIM

.net在Controller里的方法添加[HttpGet]和[HttpPost]

前端用post过来,Controller就要用[HttpPost],前端用get,Controller就要用[HttpGet],或者不管前端用什么,Controller都不加这些. 前端用post $.ajax({ url: "/CommRecord/LockSendESMS", type: "post", data: { id: data.ID, isLock: isLock }, success: function (data) { } }); Controll
