DefaultHttpClient 用 CloseableHttpClient

HttpResponse 用 CloseableHttpResponse

官方新api的樣例

Get方法：

????CloseableHttpClient?httpclient?=?HttpClients.createDefault();
????HttpGet?httpGet?=?new?HttpGet("http://targethost/homepage");
????CloseableHttpResponse?response1?=?httpclient.execute(httpGet);
????//?The?underlying?HTTP?connection?is?still?held?by?the?response?object
????//?to?allow?the?response?content?to?be?streamed?directly?from?the?network?socket.
????//?In?order?to?ensure?correct?deallocation?of?system?resources
????//?the?user?MUST?either?fully?consume?the?response?content??or?abort?request
????//?execution?by?calling?CloseableHttpResponse#close().

????try?{
????????System.out.println(response1.getStatusLine());
????????HttpEntity?entity1?=?response1.getEntity();
????????//?do?something?useful?with?the?response?body
????????//?and?ensure?it?is?fully?consumed
????????EntityUtils.consume(entity1);
????}?finally?{
????????response1.close();
????}

Post方法：

??????HttpPost?httpPost?=?new?HttpPost("http://targethost/login");
????//拼接參數(shù)
????List?<NameValuePair>?nvps?=?new?ArrayList?<NameValuePair>();
????nvps.add(new?BasicNameValuePair("username",?"vip"));
????nvps.add(new?BasicNameValuePair("password",?"secret"));
????httpPost.setEntity(new?UrlEncodedFormEntity(nvps));
????CloseableHttpResponse?response2?=?httpclient.execute(httpPost);

????try?{
????????System.out.println(response2.getStatusLine());
????????HttpEntity?entity2?=?response2.getEntity();
????????//?do?something?useful?with?the?response?body
????????//?and?ensure?it?is?fully?consumed
????????//消耗掉response
????????EntityUtils.consume(entity2);
????}?finally?{
????????response2.close();
????}

導(dǎo)入httpclient 4.2.5

導(dǎo)入httpcore 4.2.4

我跟你遇到過同樣的問題，親測有效

CloseableHttpClient httpClient = HttpClients.createDefault();
