apache http client 4.3 - 如何设置协议版本

Question

如果现在不推荐使用setParams和getParams，如何使用http client 4.3在CloseableHttpClient对象或HttpPost对象上设置协议版本？

Answer 1

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

Answer 2

或使用他们如今喜欢的那种建筑师模式：

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()
