问题 I'm trying to implement digest auth with an HTTP client, but this does not work at the moment. Can someone check if this code is correct? For testing purpose I use http://httpbin.org/, but all I get is HTTP/1.1 401 Unauthorized . Here is the example code: private static void doDigestAuth() throws ClientProtocolException, IOException, AuthenticationException, MalformedChallengeException { HttpHost target = new HttpHost("httpbin.org", 80, "http"); CredentialsProvider credsProvider = new

问题 I am trying to test this method. @Override public JSON connectResource() throws IOException { //get the location and credentials for the certificates System.setProperty("javax.net.ssl.trustStore", "C:/Program Files/Java/jdk1.7.0_40/jre/lib/security/cacerts"); System.setProperty("javax.net.ssl.trustStorePassword", "changeit"); HttpRequest httpRequest = new HttpGet(url); System.out.println("hello"); httpRequest.addHeader("Accept", "application/json"); HttpResponse response = httpClient.execute(

问题 I'm reading large documents from which I only need top 5%, can I do the following with HttpClient 4?

问题 My java application which resides in AWS private subnet connects to an http server via AWS Nat gateway. I am calling a POST request via httpclient to the HTTP server. That request will take more than 10 minutes to complete. I have configured a socket time out and connection timeout of 1 hour as this this a background task . But the intermediate AWS NAT gateway will send back a RST packet after 300 secs [5 mins] and cause the connection to get resetted , there is no way i can increase the NAT

问题 I am facing a weird issue wrto Apache HTTPS client. I am trying to connect to an external HTTPS website which has basic authentication turned on (SSL server authenticaion only). Here is the summary of my tests and conclusions.

问题 I want to perform this command with Apache http-components (4.1.2) curl --data "strings[]=testOne&string-keys[]=test.one&strings[]=testTwo&string-keys[]=test.two&project=Test" https://api.foo.com/1/string/input-bulk The target api need strings and string-keys parameters as array , which mean repeating strings[] and string-keys[] for each parameter. This curl command works fine but with Http-component, while I got exactly the same parameters. Maybe I'm doing something wrong. List<NameValuePair

问题 I am having a problem getting the Apache HttpClient to connect to a service external to my virtualised development environment. To access the internet (e.g. api.twitter.com) I need to call a local URL (e.g. api.twitter.com.dev.mycompany.net), which then forwards the request to real host. The problem is, that to whatever request I send, I get a 404 Not Found response. I have tried debugging it using wget, and it appears the problem is, that the destination server identifies the desired

问题 I have an HTTPS proxy set up so that HTTP clients can send plain HTTP requests securely to the proxy. For example, a client can send an encrypted HTTP GET request to the proxy, which will remove the encryption and send the plain HTTP GET request to the end-site. I learned that this is not a common set up and only Google Chrome has in-built features to support such a scenario. (Info here - http://wiki.squid-cache.org/Features/HTTPS#Encrypted_browser-Squid_connection). I have made Google Chrome

问题 I am using the answer here to try to make a POST request with a data upload, but I have unusual requirements from the server-side. The server is a PHP script which requires a filename on the Content-Disposition line, because it is expecting a file upload. Content-Disposition: form-data; name="file"; filename="-" However, on the client side, I would like to post an in-memory buffer (in this case a String) instead of a file, but have the server process it as though it were a file upload.
