apache-httpclient-4.x

问题 I am using Apache Http client 4.0.1 for communicating with the server. I already have a secure/non secure client code that works just fine. Recently the new addition being to add proxy to this code, so i added the following piece of code to do that (currently non secure proxy), HttpHost proxy = new HttpHost("localhost", 5555); httpClient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy); This has worked fine with a non secure request. However i am having trouble with a secure

问题 Apache HttpClient 4.3b2, HttpCore 4.3. I use PoolingHttpClientConnectionManager to manage 5 connections concurrently: PoolingHttpClientConnectionManager connectionManager; HttpClient httpclient; connectionManager = new PoolingHttpClientConnectionManager(); connectionManager.setDefaultMaxPerRoute(5); httpclient = HttpClientBuilder.create().setConnectionManager(connectionManager).build(); Server have 5 seconds keep-alive time. When server initiate close connection process it is staying in FIN

问题 I am accessing a URL that's redirecting me to a URL with spaces in it.

问题 I am shifting my REST client module from HttpClient.executeMethod(method) to RestTemplate.postForLocation(uri, obj) . With the HttpClient, I would explicitly release the connection of the method: deleteMethod.releaseConnection(); I cannot find anything equivalent within the Spring RestTemplate. Does it automatically release connections? Another way to ask would be, I suppose, is it safe to not do anything after calling the RestTemplate.postForLocation ? 回答1: One of the goals of spring

问题 I am using Apache HttpClient in one of my project. I am also using PoolingHttpClientConnectionManager along with my HttpClient as well. I am confuse what are these properties mean. I tried going through documentation in the code but I don't see any documentation around these variables so was not able to understand. setMaxTotal setDefaultMaxPerRoute setConnectTimeout setSocketTimeout setConnectionRequestTimeout setStaleConnectionCheckEnabled Below is how I am using in my code: RequestConfig

问题 I am using httpClient version 4.5 to connect with our external vendor site. We do not need any connection pool or persistent connection, so I am using the BasicHttpClientConnectionManager to create the HttpClient. This works fine for minimal number of requests, but if I test this for 1TPS for 1 hour, by the end of the test, we start seeing intermittent connection resets. (guessing request count > 100) I/O exception (java.net.SocketException) caught when processing request to {s}->https:/
