My Code is , import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.List; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client

问题 First of all, I'm not trying to start a flame-war here. I know Jersey sufficiently well, but have hardly used httpclient. What are the key differences between jersey-client and Apache's httpclient? In what areas is one better than the other? Is there a good comparison chart somewhere? Which one performs better with larger files (say 2048 MB)? Many thanks for your comments! 回答1: These two things probably should not be compared directly. Jersey is a REST-client, featuring full JAX-RS

问题 I have been searching how to implement Conscrypt SSL provider using conscrypt-openjdk-uber-1.4.1.jar for jdk8 to support ALPN for making a http2(using apache httpclient 5) connection to a server as jdk8 does not support ALPN by default or the other solution is to migrate to jdk9(or higher) which is not feasible for now as our product is heavily dependent on jdk8 I have been searching extensively for some docs or examples to implement but I could not find one. I have tried to insert conscrypt

问题 There's an api I need to perform octet-streaming from which does not have a length. It is just a stream of real time data. The issue that I'm having is that when I make my request, it seems to try to wait out for the end of the content before reading information into the inputstream, however it's not seeing the end of the content and timingout with NoHttpResponse exception. Below is a simplified version of my code: private static HttpPost getPostRequest() { // Build uri URI uri = new

问题 How would I send a string data ( JSONObject.toString() ) to a url. I want to write a static method in a util class to do this. I want the method signature to be as follows public static String postData (String url, String postData) throws SomeCustomException What should be the format of the string url The return String is the response from the server in as a string representation of json data. EDIT Present connection util package my.package; import my.package.exceptions.CustomException;

问题 I'm studying an application developed by our company. It uses the Apache HttpClient library. In the source code it uses the HttpClient class to create instances to connect to a server. I want to learn about Apache HttpClient and I've gone trough this set of examples. All the examples use CloseableHttpClient instead of HttpClient . So I think CloseableHttpClient is an extended version of HttpClient . If this is the case I have two questions: What is the difference between these two? Which
