I am calling microsoft Azureurl with restTemplate in springboot application
Url:-https://login.microsoftonline.com/{{tenantId}}/oauth2/v2.0/token
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, String> map = new LinkedMultiValueMap<>();
map.add("grant_type","client_credentials");
map.add("client_id","xxxxxxxxxxxxxxxxxxxxxxxxxx");
map.add("client_secret","xxxxxxxxxxxxxxxxxx");
map.add("scope","https://graph.microsoft.com/.default");
HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(map, headers);
ResponseEntity<String> response =
restTemplate.exchange("https://login.microsoftonline.com/xxxxxxxxxx-xxxxxx-c666dbeda42c\n/oauth2/v2.0/token",
HttpMethod.POST,
entity,
String.class);
if (response.getStatusCode() == HttpStatus.OK) {
System.out.println("Request Successful");
} else {
System.out.println("Request Failed");
}
While running the above sample call to connect with Azure, we are getting the Exception as : Caused by: java.net.UnknownHostException: login.microsoftonline.com
Later tried at home, where there is no Proxy to connect to the internet, and then am able to successfully get output without this "UnknownHostException" error.
So how to resolve the issue.
Your url seems to be not specification https://login.microsoftonline.com/xxxxxxxxxx-xxxxxx-c666dbeda42c\n/oauth2/v2.0/token, try to change it to: https://login.microsoftonline.com/xxxxxxxxxx-xxxxxx-c666dbeda42c/oauth2/v2.0/token . Remove \n.
I have the same error for a missing proxy configuration. (I was googling for solutions for a specific case)
"Host not found" has nothing to do with the url parameters, but as said just before, having "\n" in an url is never a good idea.

I am trying consume a SOAP web Service and I have written my SOAP client using Spring-ws. This also included a message signing. However when I am trying to trigger a request I am getting the exception. From the server standpoint, the server is sending a successful response but I am not able to unmarshall it.
I followed quite a few suggestion including one from this
UnmarshallingFailureException, unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault")
Following the above link however removed the exception but in turn I am getting a null response object and I could not trace out where the response went missing.
This is my Config class methods:
public WebServiceTemplate accountsInquiryWebServiceTemplate() throws Exception {
WebServiceTemplate webServiceTemplate = new WebServiceTemplate();
Jaxb2Marshaller accountsInquiryMarshaller = accountsInquiryMarshaller();
webServiceTemplate.setMarshaller(accountsInquiryMarshaller);
webServiceTemplate.setUnmarshaller(accountsInquiryMarshaller);
ClientInterceptor[] clientInterceptors = new ClientInterceptor[1];
clientInterceptors[0] = wsClientSecurityInterceptor();
webServiceTemplate.setInterceptors(clientInterceptors);
webServiceTemplate.setCheckConnectionForFault(true);
webServiceTemplate.setDefaultUri(serviceURL);
return webServiceTemplate;
}
private Jaxb2Marshaller accountsInquiryMarshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPaths(new String[]{
"com.accounting.integrationservice"
});
return jaxb2Marshaller;
}
private Wss4jSecurityInterceptor wsClientSecurityInterceptor() throws Exception {
Wss4jSecurityInterceptor wss4jSecurityInterceptor = new Wss4jSecurityInterceptor();
wss4jSecurityInterceptor.setSecurementActions("Signature");
wss4jSecurityInterceptor.setSecurementUsername(username);
wss4jSecurityInterceptor.setSecurementPassword(password);
wss4jSecurityInterceptor.setSecurementSignatureCrypto(clientCrypto());
wss4jSecurityInterceptor.setValidationActions("Signature");
return wss4jSecurityInterceptor;
}
private Crypto clientCrypto() throws Exception {
CryptoFactoryBean cryptoFactoryBean = new CryptoFactoryBean();
cryptoFactoryBean.setKeyStoreLocation(resourceLoader.getResource("classpath:accountsInquiry/keystore/" + keyStoreLocation));
cryptoFactoryBean.setKeyStorePassword(keyStorePassword);
cryptoFactoryBean.afterPropertiesSet();
return cryptoFactoryBean.getObject();
}
The client calls as below:
Response response = accountsWebServiceTemplate.marshalSendAndReceive(request);
The exception stack that I am getting is as below : Its similar to the referred link above, so not putting the entire exception stack
org.springframework.ws.soap.security.AbstractWsSecurityInterceptor.handleResponse(AbstractWsSecurityInterceptor.java:247)
- Could not validate request: No WS-Security header found
org.springframework.oxm.UnmarshallingFailureException: JAXB unmarshalling exception; nested exception is javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault").

Ok So, I was trying to use "Signature" to validate the Security Header of the response even though there was no header. But thing is if I didn't specify the ValidationAction it was throwing NullPointerException so it was expecting at least one ValidationAction.
To counter all this I told the Spring security not to validate the response by this piece of code.
wss4jSecurityInterceptor.setValidateResponse(false);
Thanks to this article

I need to create an SOAP client with JAX-WS on JBoss.
The Problem is I cannot get past the authentication.
I have a test implemented in SoapUI which works when I set the request properties username and password
With the following code
URL kbaURL = new URL("http://...");
IkfzService ikfzService = new IkfzService(kbaURL);
IkfzPortType ikfzPortType = ikfzService.getIkfzSOAP();
Map<String, Object> requestContext = ((BindingProvider)ikfzPortType).getRequestContext();
requestContext.put(BindingProvider.USERNAME_PROPERTY, "...");
requestContext.put(BindingProvider.PASSWORD_PROPERTY, "...");
Where URL, username und password are the same like in SOAPUI I am getting
javax.xml.ws.WebServiceException: org.apache.cxf.service.factory.ServiceConstructionException:
Failed to create service.
...
Caused by: javax.wsdl.WSDLException: WSDLException: faultCode=PARSER_ERROR:
Problem parsing 'http://..'.: java.io.IOException: Server returned HTTP response code:
401 for URL: http://..
What am I missing?
This should be a basic example of what you're trying to accomplish - let me know if you need more help or clarification
//the WSDL/webservice endpoint
private static final String WSDL_URL = "http://localhost:8080/MyWebService/MyWebService?wsdl";
URL url = new URL(WSDL_URL);
QName qname = new QName("http://ws.mycompany.com/", MyWebServiceImpl");
Service theWSService = Service.create(url, qname);
//returns the interface for MyWebServiceImpl
TheWSServiceIF port = theWSService.getPort(TheWSServiceIF.class);
//Setup Security
Map<String, Object> requestContext = ((BindingProvider)port).getRequestContext();
requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, WS_URL);
Map<String, List<String>> requestHeaders = new HashMap<String, List<String>>();
requestHeaders.put("Username", Collections.singletonList("myUserName"));
requestHeaders.put("Password", Collections.singletonList("myPasword"));
requestContext.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
/**********************************************************************/
//actually call the web service method, print results
System.out.println(port.getMyWebServiceData());
Im not sure if this should just go direct to the github but I thought id check here first if anyone has encountered this issue before.
I recently have upgraded one of my apps to use dot net 2.0.3 From 1.1.4.
Everything works fine locally but when I deploy to my app service in azure I get the following exception.
System.Text.DecoderFallbackException: Unable to translate bytes [8B] at index 1 from specified code page to Unicode.
The code that calls it is a httpclient that talks between the apps.
public async Task<T1> Get<T1>(string url, Dictionary<string, string> urlParameters = null) where T1 : DefaultResponse, new()
{
var authToken = _contextAccessor.HttpContext.Request.Cookies["authToken"];
using (var client = new HttpClient().AcceptJson().Acceptgzip().AddAuthToken(authToken))
{
var apiResponse = await client.GetAsync(CreateRequest(url, urlParameters));
T1 output;
if (apiResponse.IsSuccessStatusCode)
{
output = await apiResponse.Content.ReadAsAsync<T1>();
//output.Succeeded = true;
}
else
{
output = new T1();
var errorData = GlobalNonSuccessResponseHandler.Handle(apiResponse);
output.Succeeded = false;
output.Messages.Add(errorData);
}
return output;
}
}
public static HttpClient AcceptJson(this HttpClient client)
{
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
return client;
}
public static HttpClient Acceptgzip(this HttpClient client)
{
// Commenting this out fixes the issue.
//client.DefaultRequestHeaders.AcceptEncoding.Add(StringWithQualityHeaderValue.Parse("gzip"));
client.DefaultRequestHeaders.AcceptEncoding.Add(StringWithQualityHeaderValue.Parse("deflate"));
return client;
}
public static HttpClient AddAuthToken(this HttpClient client, string authToken)
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authToken);
return client;
}
Im a bit stumped as to whats going on.
So I have 2 apps which we call client and server from now on.
Client uses the above code to talk to the server.
Locally this is fine on azure not so, this all worked fine before upgrading.
So I setup the client locally to talk to the server on azure I was able to replicate the issue.
I had a look at the response in fiddler and it is able to correctly decode it.
If anyone has any idea where I should look and has seen it before any info would be great :D.
UPDATE 1
So after some more digging I decided to remove gzip and then everything started working.
client.DefaultRequestHeaders.AcceptEncoding.Add(StringWithQualityHeaderValue.Parse("gzip"));
Can anyone explain this?
8B can be a second byte of multi-byte UTF8 character. The DecoderFallbackException tells that you’re interpreting the data as some other encoding. Probably Latin-1 which doesn’t have 8B character.
In fiddler, you should look at the content-type HTTP header in the response. If it says application/json or application/json; charset=utf-8, it’s probably a bug in .NET, because even without charset=utf-8 RFC 4627 says the default encoding is already UTF-8.
If it says something else, I would try changing the server so it sends the correct content-type header in the response.
I'm using Volley to send an http post request with parameters from my android app to my local server running in http://192.168.1.4:3000/battery_signal_report
I'm pretty sure the server is running properly (I checked it with Postman successfully).
also, I successfully sent the request through Android Studio's Emulator using ip 10.0.2.2
Trying to make it work, i used various request implementations including JsonObjectRequest, StringRequest and the custom request described here: Volley JsonObjectRequest Post request not working
Also, I've read somewhere that Volley post requests have some problems with the request header, so i tried to override it in different ways.
Nothing works. onErrorResponse is called every time with an empty VolleyError input.
I've fairly new to android development, so any insights would be much appreciated.
Thanks in advance.
For anyone else coming across this, you need to forget about the header override and setup your own getBodyContentType() and getBody() methods. Follow this pattern:
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, successListener, errorListener) {
#Override
public String getBodyContentType() {
return "application/json; charset=utf-8";//set here instead
}
#Override
public byte[] getBody() {
try {
Map<String, String> params = yourObject.getMappedParams();
JSONObject json = new JSONObject(params);
String requestBody = json.toString();
return requestBody == null ? null : requestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
return null;
}
}
};
I am trying to get back a profile for myself but I only get back a successful http response...no data. This is the code I am using.
try {
RestClient restClient = new RestClient("https://apps.na.collabserv.com","my.email","my.password");
Response<AtomFeed> responseFeed = restClient.doGet("/profiles/atom/profileService.do").asAtomFeed();
System.out.println(responseFeed.getData().toXmlString());
} catch(Exception e) {
e.printStackTrace();
}
If I try to add a email= to the url I get a 403 forbidden return.
Not really sure what the issue is,
Thanks!
