its seems i have a bug but i cant find any clue in google.
i have the following code:
DefaultHttpClient httpClient = new DefaultHttpClient();
setupHTTPS(httpClient);
HttpContext context = new BasicHttpContext();
// set proxy data, if available
if (proxyHost != null) {
httpClient.getCredentialsProvider().setCredentials(new AuthScope(proxyHost, proxyPort), new UsernamePasswordCredentials(proxyUsername, proxyPassword));
HttpHost proxy = new HttpHost(proxyHost, proxyPort);
httpClient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
}
RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();
httpClient.setRedirectStrategy(redirectStrategy);
HttpGet request = new HttpGet(url);
// allow circle redirect with limiting the numbers of redirects
httpClient.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
httpClient.getParams().setParameter(ClientPNames.MAX_REDIRECTS, 50);
// set userAgent , if available
if(userAgent!=null){
setUserAgentForHttpClient(userAgent,httpClient);
}
HttpResponse response = httpClient.execute(request, context);
RedirectLocations locations = (RedirectLocations) context.getAttribute(DefaultRedirectStrategy.REDIRECT_LOCATIONS);
and i tried to run it on url: http://annemergmed.com/action/consumeSharedSessionAction?JSESSIONID=aaaiJSrshFbnYctW3Q4Rv&MAID=I1JsdfY3Lc%2FzCjqdBXuiSQ%3D%3D&SERVER=WZ6myaEXBLHj3ZzqSv9HPw%3D%3D&ORIGIN=378011271&RD=RD&acw=&utt=
but i got different location from what i see in firebug. totaly different! (i am runing firebug on privat browsing)
how can it be? what am i missing?

I can get to https://pushover.net/ using chrome browser, but when i try to get to the same website using java to connect to the api and send data it fails.
this is my code
HttpClient httpClient = (HttpClient) HttpClientBuilder.create()/*.setProxy(proxy)*/.build();
HttpPost post = new HttpPost("https://api.pushover.net/1/messages.json");
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("token", apiToken));
nvps.add(new BasicNameValuePair("user", userKey));
nvps.add(new BasicNameValuePair("message", message));
post.setEntity(new UrlEncodedFormEntity(nvps, Charset.defaultCharset()));
//point A
HttpResponse deviceResponse = httpClient.execute(post);
//point B
it gets to point A, but then takes ages to get to point B and it gives an exception when it does.
The Exception is
org.apache.http.conn.HttpHostConnectException: Connect to api.pushover.net:443 (api.pushover.net/108.59.13.232] failed: Connection timer out: connect.
I have tried using a proxy with the below code above the rest
HttpHost proxy = new HttpHost("url",9090,"https");
httpClient = (HttpClient) HttpClientBuilder.create().setProxy(proxy).build();
This gives me a
javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
I then also tried adding
Authenticator.setDefault(
new Authenticator() {
#Override
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(
authUser, authPassword.toCharArray());
}
}
);
System.setProperty("http.proxyUser", authUser);
System.setProperty("http.proxyPassword", authPassword);
but it gives the same SSLHandshakeException.
I have seen things on creating keystores, but that will only work on my machine, I want something that will work in code and allow me to deploy this app to 1000's of machines, without having to do extra manual config to each.
Is there anything Better i should be doing?
I have fixed it with this code in place of the httpClient at the beginning.
HttpHost proxy = new HttpHost(PROXY_URL, 8080);
DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
AuthCache authCache = new BasicAuthCache();
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(PROXY_URL, 8080, AuthScope.ANY_HOST, "ntlm"), new NTCredentials(authUser, authPassword, "",PROXY_DOMAIN));
HttpClientContext context = HttpClientContext.create();
context.setCredentialsProvider(credsProvider);
context.setAuthCache(authCache);
httpClient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).setRoutePlanner(routePlanner).build();
I am trying to use httpclient to make make a call to Jenkins to get a list of jobs.
When I run my code, I get an UnknownHostException.
I tried to make the same request using curl and I was able to get the result. I am not sure how to interpret this.
void nwe() throws ClientProtocolException, IOException {
HttpHost target = new HttpHost("https://<JENKINS_URL>/api");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope(target.getHostName(), target.getPort()),
new UsernamePasswordCredentials("username", "password"));
CloseableHttpClient httpclient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
HttpGet httpGet = new HttpGet("/json");
httpGet.setHeader("Content-type", "application/json");
BasicScheme basicAuth = new BasicScheme();
HttpClientContext localContext = HttpClientContext.create();
CloseableHttpResponse response1 = httpclient.execute(target, httpGet, localContext);
System.out.println(response1.getStatusLine());
}
The CURL command on the same URL gives me the expected output
Thanks,
Amar
Read the JavaDoc for HttpHost:
Parameters: hostname - the hostname (IP or DNS name)
So you should use just (omit the protocol and context):
HttpHost target = new HttpHost( "<JENKINS_URL>" );
and then HttpGet the /api/json part.
Cheers,
My problem is i'm trying to get into scopus using a crawler but it requires my crawler to enter the site through my school proxy server. I tried authenticating but it keep responding with 401 status.
public void testConnection() throws ClientProtocolException, IOException {
DefaultHttpClient httpclient = new DefaultHttpClient();
List<String> authpref = new ArrayList<String>();
authpref.add(AuthPolicy.NTLM);
httpclient.getParams().setParameter(AuthPNames.TARGET_AUTH_PREF, authpref);
NTCredentials creds = new NTCredentials("username","password","ezlibproxy1.ntu.edu.sg","ntu.edu.sg");//this is correct
httpclient.getCredentialsProvider().setCredentials(AuthScope.ANY, creds);
HttpHost target = new HttpHost("ezlibproxy1.ntu.edu.sg", 443, "https");//this is correct
// Make sure the same context is used to execute logically related requests
HttpContext localContext = new BasicHttpContext();
// Execute a cheap method first. This will trigger NTLM authentication
HttpGet httpget = new HttpGet("http://www-scopus-com.ezlibproxy1.ntu.edu.sg/authid/detail.url?authorId=14831850700");
HttpResponse response = httpclient.execute(target, httpget, localContext);
HttpEntity entity = response.getEntity();
System.out.println(EntityUtils.toString(entity));
int statusCode = response.getStatusLine().getStatusCode();
System.out.println("Status Code:" + statusCode);
}
The status code respond is 401 (unauthorised).
Any suggestion on this?
I'm trying to access a RESTful web service through the Android Emulator on my PC, which uses a proxy to connect to the internet.
I have code working fine to access the web service on an actual Android device that has its own data connection with the following code:
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpGet request = new HttpGet("http://mytesturl.com/services/serviceName");
UsernamePasswordCredentials creds =
new UsernamePasswordCredentials("username", "password");
request.addHeader(BasicScheme.authenticate(creds, "UTF-8", false));
HttpResponse response = client.execute(request);
I've tried a number of approaches to try to get the Emulator to allow connection through the proxy, but none have worked.
Note, I do have the INTERNET enabled in AndroidManifest.xml:
<uses-permission android:name="android.permission.INTERNET" />
Attempt 1 - Setting Properties:
This produces an UnknownHostException for the URL of my service at the execute() call
Properties props = System.getProperties();
props.put("http.proxyHost", "httpproxy.mycompany.com");
props.put("http.proxyPort", "80");
Attempt 2 - Setting the proxy in the DefaultHttpClient:
This produces an UnknownHostException for the actual proxy
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpHost proxy = new HttpHost("httpproxy.mycompany.com", 80);
client.getCredentialsProvider().setCredentials(
new AuthScope("httpproxy.mycompany.com", 80),
new UsernamePasswordCredentials("username", "password"));
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
HttpGet request = new HttpGet("http://mytesturl.com/services/serviceName");
UsernamePasswordCredentials cred =
new UsernamePasswordCredentials("username", "password");
request.addHeader(BasicScheme.authenticate(cred, "UTF-8", false));
HttpResponse response = client.execute(request);
Attempt 3 - Setting the proxy in the HttpGet
This produces an UnknownHostException for the URL in my HttpGet
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpGet request = new HttpGet("http://mytesturl.com/services/serviceName");
UsernamePasswordCredentials cred =
new UsernamePasswordCredentials("username", "password");
request.addHeader(BasicScheme.authenticate(cred, "UTF-8", false));
Header bs = new BasicScheme().authenticate(
new UsernamePasswordCredentials("username", "password"),
request);
request.addHeader("Proxy-Authorization", bs.getValue());
HttpResponse response = client.execute(request);
I'm not sure what else to try. I'm open to any suggestions.
Having the same problem, I succeeded with a variation on attempt 3 (code below), the cruicial difference being the setProperty statements. Note that the web service I am calling does not require authentication so I'm only setting the proxy authorization header.
System.setProperty("java.net.useSystemProxies", "false");
System.setProperty("http.proxyHost", "123.56.7.9");
System.setProperty("http.proxyPort", "8080");
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpGet request = new HttpGet("web service url");
Header bs = new BasicScheme().authenticate(
new UsernamePasswordCredentials("NETWORKID", "netpassword"),
request);
request.addHeader("Proxy-Authorization", bs.getValue());
HttpResponse response = client.execute(request);
did you use -http-proxy http://: emulator command line option or "Settings" -> "Wireless & Networks" -> "Mobile Networks" -> "Access Point Names" -> "Telkila" or Home > Menu > Settings > Wireless Controls > Mobile Networks > Access Point Names?
I am trying to make a simple GET request for a website, but I am getting unknown host exception.
Given below is my code--
DefaultHttpClient client = new DefaultHttpClient();
HttpHost targetHost=null;
targetHost= new HttpHost("google.com/", 80, "http");
HttpGet httpget = new HttpGet("about-us.html");
BasicHttpContext localcontext = new BasicHttpContext();
try {
HttpResponse response = client.execute(targetHost, httpget, localcontext);
It looks like you have a simple problem here.
The URL for your 'HttpHost' object is malformed. You need to drop the '/' from "google.com/".
It should work after that. I used your code with that single modification & it worked.
DefaultHttpClient client = new DefaultHttpClient();
HttpHost targetHost = new HttpHost("google.com", 80, "http");
HttpGet httpget = new HttpGet("about-us.html");
BasicHttpContext localContext = new BasicHttpContext();
HttpResponse response = null;
try { response = client.execute(targetHost, httpget, localContext);
System.out.println(response.getStatusLine()
}
catch(Exception e){
// Enter error-handling code here.
}
