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();

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 am a newbie attempting to send data from an Android app to a MySQL database set up on a localhost server via xampp. This method is supposed to put a name, username, password, phone number, and age into an arraylist of type NameValuePair.
#Override
protected Void doInBackground(Void... params) {
ArrayList<NameValuePair> dataToSend = new ArrayList<>();
dataToSend.add(new BasicNameValuePair("name", user.name));
dataToSend.add(new BasicNameValuePair("age", user.age + ""));
dataToSend.add(new BasicNameValuePair("username", user.username));
dataToSend.add(new BasicNameValuePair("password", user.password));
dataToSend.add(new BasicNameValuePair("phoneNumber", user.phoneNumber));
HttpParams httpRequestParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpConnectionParams.setSoTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpClient client = new DefaultHttpClient(httpRequestParams);
HttpPost post = new HttpPost("localhost/Register.php");
try{
post.setEntity(new UrlEncodedFormEntity(dataToSend));
client.execute(post);
}catch(Exception e){
e.printStackTrace();
}
return null;
}
When I run the application, I receive the following exception:
Target host must not be null, or set in parameters. scheme=null, host=null, path=localhost/Register.php
My research leads me to believe that there's a problem with the url string, but I don't know specifically what the issue is.
Thanks in advance.
(P.S. I am also aware of the awful security implications of storing a password in plain text on a database. Just trying to learn how to interact between apps and databases. Thx)
Try this code to post data if the localhost replacement doesn't work for you.
HttpParams params = new DefaultHttpParams(); // setup whatever params you what
HttpClient client = new DefaultHttpClient(params);
HttpPost post = new HttpPost("someurl");
post.setEntity(new UrlEncodedFormEntity()); // with list of key-value pairs
client.execute(post, new ResponseHandler(){}); // implement ResponseHandler to handle response correctly.
My issue was simply that I was using the wrong ip address. For some reason or another, localhost does not work. I figured out my system's ipv4 address (not 10.0.2.2) and used that and it worked.
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,
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 develop a java http client with apache httpcomponents 4.0.1. This client calls the page "https://myHost/myPage". This page is protected on the server by a JNDIRealm with a login form authentication, so when I try to get https://myHost/myPage I get a login page. I tried to bypass it unsuccessfully with the following code :
//I set my proxy
HttpHost proxy = new HttpHost("myProxyHost", myProxyPort);
//I add supported schemes
SchemeRegistry supportedSchemes = new SchemeRegistry();
supportedSchemes.register(new Scheme("http", PlainSocketFactory
.getSocketFactory(), 80));
supportedSchemes.register(new Scheme("https", SSLSocketFactory
.getSocketFactory(), 443));
// prepare parameters
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "UTF-8");
HttpProtocolParams.setUseExpectContinue(params, true);
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params,
supportedSchemes);
DefaultHttpClient httpclient = new DefaultHttpClient(ccm, params);
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
proxy);
//I add my authentication information
httpclient.getCredentialsProvider().setCredentials(
new AuthScope("myHost/myPage", 443),
new UsernamePasswordCredentials("username", "password"));
HttpHost host = new HttpHost("myHost", 443, "https");
HttpGet req = new HttpGet("/myPage");
//show the page
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String rsp = httpClient.execute(host, req, responseHandler);
System.out.println(rsp);
When I run this code, I always get the login page, not myPage. How can I apply my credential parameters to avoid this login form?
Any help would be fantastic
HttpClient doesn't support form login. What you are trying to do is Basic Auth, which does't work with form login.
You can simply trace the form post for login page and send the POST request from HttpClient.
