问题 This question already has answers here : Unrecognized SSL message, plaintext connection? Exception (19 answers) Closed 4 years ago . I am trying to setup a java application to connect to Hashicorp's vault and authenticate using the TLS backend (using an SSL Certificate) I am using apache httpcomponents 4.4 as follows: final CloseableHttpClient httpclient = HttpClients.custom().setSSLContext(mySslContext).build(); final CloseableHttpResponse response = httpclient.execute(myRequest) where

问题 I'd like to monitor the connection pool of a Apache httpComponents PoolingHttpClientConnectionManager but cannot find a way to access it. We create our HttpClient using the following builder: HttpClient httpClient = HttpClientBuilder.create() .setMaxConnTotal(maxConnections) .setMaxConnPerRoute(maxConnectionsPerRoute) .build(); This creates an instance of an InternalHttpClient , which holds an instance of a PoolingHttpClientConnectionManager , which holds an instance of a CPool . CPool would

问题 In previous versions of HttpClient target host was set up into client itself. In last version (for HttpAsyncClient it's 4.1.1) host is set up into HttpRequest ( HttpGet , HttpPost etc.) every time I do a request. I want to use persistent connection, so I use HttpAsyncClient . I create and use it like this: CloseableHttpAsyncClient client = HttpAsyncClients.createDefault(); client.start(); List<Future<HttpResponse>> responses = new ArrayList<>(); for (int i = 0; i < 10; i++) { HttpGet get =

问题 Why does the following Code returns -1? Seems that the request failed. public static void main(String[] args) { DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet httpGet = new HttpGet("http://www.google.de"); HttpResponse response; try { response = httpClient.execute(httpGet); HttpEntity entity = response.getEntity(); EntityUtils.consume(entity); // Prints -1 System.out.println(entity.getContentLength()); } catch (ClientProtocolException e) { e.printStackTrace(); } catch

问题 I'm trying to mimic my Browsers behaviour on a multipart/form-data POST request using org.apache.http.entity.mime.MultipartEntityBuilder My browser only sends Content-Disposition, but no Content-Type or Content-Transfer-Encoding Headers. I tried to use MultipartEntityBuilder.addPart() and addTextBody() but both add those Headers by default: What I want (what my chrome browser does): POST .../some.jsp HTTP/1.1 Host: ... Connection: keep-alive Content-Type: multipart/form-data; boundary=---

问题 I'm using org.apache.http.ssl.SSLContextBuilder to provide my certificate/keys in my HTTPS requests, but I would like to customize my SNI in TLS Handshake and I'm not sure where I can do this Does Apache Java Lib allow this customization? I found https://hc.apache.org/httpcomponents-client-4.5.x/httpclient/apidocs/org/apache/http/conn/ssl/SSLConnectionSocketFactory.html and How to enable SNI in HTTP request using Apache HTTPComponents HttpClient? but both does not have anything about methods

问题 I have been working around Google OAuth 2.0 with java and got struck with some unknown error during implementation. The following CURL for POST request works fine: curl -v -k --header "Content-Type: application/x-www-form-urlencoded" --data "code=4%2FnKVGy9V3LfVJF7gRwkuhS3jbte-5.Arzr67Ksf-cSgrKXntQAax0iz1cDegI&client_id=[my_client_id]&client_secret=[my_client_secret]&redirect_uri=[my_redirect_uri]&grant_type=authorization_code" https://accounts.google.com/o/oauth2/token And produces the

问题 I am converting some code from the Http Client 3.x library over to the Http Components 4.x library. The old code contains a check to make sure that the response is not over a certain size. This is fairly easy to do in Http Client 3.x since you can get back a stream from the response using the getResponseBodyAsStream() method and determine when the size has been exceeded. I can't find a similar way in Http Components. Here's the old code as an example of what I'm trying to do: private static

问题 I am in a weird situation, which I have no idea what's going on. The code was working, until I upgraded my Android SDK to r17. The code is able to compile, but during runtime, Eclipse throws ClassNotFoundException() , under findClass method, in PathClassLoader.class The class that not found are "org.apache.http.entity.mime.content.ContentBody" and "org.apache.http.entity.mime.content.StringBody" I already imported in the latest (4.1.3) http components jar file into project-> properties-> java
