apache http client 4.3 - 如何设置协议版本

Question

如何设置协议版本在具有http客户端4.3的CloseableHttpClient对象或HttpPost对象上，现在setParams和getParams已被弃用？

Answer 1

HttpPost post = new HttpPost("/"); 
post.setProtocolVersion(HttpVersion.HTTP_1_1); 

Answer 2

，或者使用生成器模式，他们是如此喜欢这些天：

final HttpUriRequest request = RequestBuilder.post() 
    .setVersion(HttpVersion.HTTP_1_1) 
    .setUri(requestURI) 
    .addHeader(key, value) 
    .... <whaterver more you want to add to the request>   
    .build()
