解析响应内容

//执行请求
CloseableHttpResponse response = httpClient.execute(httpPost);
//获取所有响应头
//Header[] getAllHeaders()
//Header[] getHeaders(name)
Header[] allHeaders = response.getAllHeaders();
for(Header header : allHeaders){
    System.out.println(header.getName()+" : " + header.getValue());
}

//获取响应状态行，进而获取响应状态码
int statusCode = response.getStatusLine().getStatusCode();
System.out.println("状态码：" + statusCode);

//获取响应的MIME类型
String contentMimeType = ContentType.getOrDefault(response.getEntity()).getMimeType();
System.out.println("媒体类型：" + contentMimeType);

//获取响应的内容，这里只演示简单的文本内容，实际开发中并不总是这么简单，后面详细地讲解
String bodyAsString = EntityUtils.toString(response.getEntity(),"UTF-8");
System.out.println("响应内容：" + bodyAsString);
