apache-httpclient-4.x

问题 I have trouble adding NTLM authentication to my existing application that uses Jersey and Apache HttpClient. I was only able to authenticate using JCIFS, the default NTLM authentication from HttpClient does not work (I get 401 ). The example from Apache HttpClient page shows how to use CloseableHttpClient: https://hc.apache.org/httpcomponents-client-4.5.x/ntlm.html Registry<AuthSchemeProvider> authSchemeRegistry = RegistryBuilder.<AuthSchemeProvider>create() .register(AuthSchemes.NTLM, new

问题 I am trying to use Apache HTTPClient 4.5.1 to do some rest requests. Unfortunately every second request ends up in "java.net.SocketTimeoutException: Read timed out" (or hangs forever if the socket timeout is not set). I am building my client like this: ConnectionSocketFactory sf = new PlainConnectionSocketFactory(); Registry<ConnectionSocketFactory> r = RegistryBuilder.<ConnectionSocketFactory> create() .register("http", sf) .build(); Lookup<AuthSchemeProvider> authProviders = RegistryBuilder

问题 I am trying to use REST calls to Neptune SPARQL on existing Java code which already uses Apache HTTP clients. I'd like to not mix and match AWS SDK1 and SDK2 (which I use for the S3 portion of loading owl to Neptune). I see these solutions: AWSRequestSigningApacheInterceptor that works with SDK1, but can't find the equivalent in SDK2. aws-request-signing-apache-interceptor on github for building an adaptor class so it can be used in SDK 2 with mix-and-match SDK 1 & 2 javaquery/Examples where

问题 I'm trying to use apache httpclient to load images with caching. After request the file is saved but after repeating same request it begins to download again and new file saved as cache. So cached images not reused. And not deleting. File names differ only by hash 1389449846612.0000000000000001-3f1e8b88.localhost.-images-goods-212250-7841874.jpg 1389449952782.0000000000000001-5720e341.localhost.-images-goods-212250-7841874.jpg I want, that image will be loaded once and be able to show cached

问题 I am trying to access another service by Http to fetch data using HttpClient. The uri should look like endpoint:80/.../itemId. I am wondering if there is a way to make a batch call to specify a set of itemIds? I did find someone suggests to .setHeader(HttpHeaders.CONNECTION, "keep-alive") when creating request. Via doing this, how could I release the client after getting all data? Also, seems like this method still need to get one response then send another request? Is this possible to do it

问题 Looking at the quick start guide it gives the following code example: CloseableHttpClient httpclient = HttpClients.createDefault(); HttpGet httpGet = new HttpGet("http://targethost/homepage"); CloseableHttpResponse response1 = httpclient.execute(httpGet); // The underlying HTTP connection is still held by the response object // to allow the response content to be streamed directly from the network socket. // In order to ensure correct deallocation of system resources // the user MUST call

问题 I want to upload a file using HttpClient 4.3.1. I need to add to form multipart an inputstream (to control upload progress.) instead of a File object. This is my code: byte[] dump = ...; HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(SENDLOG_URL); MultipartEntityBuilder meb = MultipartEntityBuilder.create(); meb.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); // THIS WORKS!! meb.addBinaryBody("log", new File("C:\\temp.zip"), ContentType.APPLICATION_OCTET

问题 I am using Apache Http client for making use of ElasticSearch Rest Api, but I am always getting HTTP error code as 200. Please help Java code import java.io.BufferedReader; import java.io.File; import java.io.IOException; import java.io.InputStreamReader; import java.net.MalformedURLException; import java.util.Scanner; import org.apache.http.HttpResponse; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client

问题 I have what I would think was a typical use case. I am using Apache HttpClient to make a POST to a remote (internal) server. The response from the server is XML. I get the response from the entity as a stream and parse it directly to an XML Document. This code snippet shows what I am doing. HttpResponse response = httpClient.execute(request); int code = response.getStatusLine().getStatusCode(); if(code != 200) { returnValue.addParameter("msg", "Recieved invalid status code '" + code + "'"); }
