如何用RequestConfig替换弃用的httpClient.getParams（）CoreProtocolPNames.USE_EXPECT_CONTINUE？

Question

我继承的代码

HttpPost httpPost = new HttpPost(url); 
    httpPost.getParams().setBooleanParameter(
       CoreProtocolPNames.USE_EXPECT_CONTINUE, false); 
     StringEntity entity = new StringEntity(parameter, "utf-8"); 
    httpPost.setEntity(entity); 
     if(headers != null){ 
      Set<String> headersKey = headers.keySet(); 
      for (String key : headersKey) { 
       httpPost.setHeader(key, headers.get(key)); 
      } 
     } 
     return httpclient.execute(httpPost); 

httpClient.getParams()被@Deprecated和写着“

有用于RequestConfig没有类的文档，我不知道应该用什么方法来代替httpPost.getParams().setBooleanParameter和CoreProtocolPNames.USE_EXPECT_CONTINUE

创建httpClient时可以设置，试试这个：

RequestConfig defaultRequestConfig = RequestConfig.custom().setConnectTimeout(CONN_TIMEOUT) 
         .setExpectContinueEnabled(false).build(); 
HttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig) 
         .build();
