I have developed a REST Web service to get resources, I am able to access it through Java/Spring Template and even the xml response is coming if I type the URI on browser.
But when I invoke the same URI using XMLHttpRequest in Java script I am getting the below error.
"XMLHttpRequest cannot load URI(actual uri with server name ..etc) . Origin file:// is not allowed by Access-Control-Allow-Origin."
Uncaught Error: NETWORK_ERR: XMLHttpRequest Exception 101.
My JS code is as below.
xmlHttp = new XMLHttpRequest();
xmlHttp.open( "GET", "http://localhost:8080/rest/apps", false );
xmlHttp.send( null );
Please let me know what would be the problem and help me to resolve this.

here Origin is the local file system, that you're loading the HTML page, that load call via a file:/// . the request is from the same origin. If you're trying to load from somewhere else then you will not get the Error.

I'm getting an Exception when running this, but Jenkins actually executes the requested action:
URL url = new URL("https://somehost.com/jenkins/quietDown");
HttpURLConnection c= (HttpURLConnection) url.openConnection();
c.setRequestMethod("POST");
c.setRequestProperty("Authorization", "Basic " + Base64.getEncoder().encodeToString(("user:apiToken").getBytes()));
c.getInputStream().close();
Exception:
Exception in thread "main" java.io.IOException: Server returned HTTP response code: 403 for URL: https://somehost.com/jenkins/
at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1894)
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1492)
at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:263)
at build.JenkinsClient.main(JenkinsClient.java:102)
Testing with Jenkins 2.164.3 and Java 8.
Setting this gets rid of the Exception:
connection.setInstanceFollowRedirects(false);
After hours I noticed how the stack trace contained a slightly different URL than the one I was posting to:
https://somehost.com/jenkins/
vs
https://somehost.com/jenkins/quietDown
It seems like Jenkins answers with a redirect (302 Found), which the HttUrlConnections follows by default to read from, which then for some reason caused that exception.
For the longest time, I tried to figure out a way to issue the POST request without calling connection.getInputStream(), but that seems to be the only call which actually triggers the request. If anyone knows a different way to issue a POST request with pure Java, please let me know.
I knew my URL and username:token stuff was correct because I tested with curl (which doesn't complain, even with the follow redirect option turned on):
curl -X POST https://somehost.com/jenkins/quietDown -u admin:token
curl -L -X POST https://somehost.com/jenkins/quietDown -u admin:token
I am facing an error and I don't known what to do. Whenever I try to save user to my ionic user service using the following code:
Ionic.io();
var user = Ionic.User.current();
if (user.id) {
user.set('name', username);
//user.set('image',image_name);
}
user.save();
and then I get this error:
Ionic User: Error: CORS request rejected
XMLHttpRequest cannot load https://api.ionic.io/auth/users/null.
Response for preflight has invalid HTTP status code 404
OPTIONS https:// api .ionic .io /auth /users /null
[cors request rejected][1]
[coding][2]
Ionic has a cordova plugin that sorts out all CORS issues called "cordova-plugin-whitelist". When you test through the browser, the Cordova plugins are not active, hence it's not sorting out your issues. Only when you deploy your app to android/ios/windows will the Cordova plugins work.
Rather get "Allow-Control-Allow-Origin" chrome plugin to allow you to make requests if you want to test on your browser.
My coldfusion version is 10 and configured with iis. I have configured Rest service using the following code
<cfset restInitApplication(getDirectoryFromPath(getCurrentTemplatePath()), "myservicename") />
My cfc which is in same directory looks something like that
component restpath="test" rest="true" produces="application/json"
{
remote array function getResult(
required string tmpID restargsource="path",
string startDate restargsource="query",
string endDate restargsource="query"
)
httpmethod="GET"
restpath="{tmpID}"
{
return arguments.tmpID;
}
}
I am trying to access the rest service by url but it is giving me 404 not found error. Here is url which i have tried.
http://localhost:8500/rest/myservicename/test/10221
http://example.com/rest/myservicename/test/10221
http://127.0.0.1/rest/myservicename/test/10221
But all three is not working for me. When i try to refresh the service from coldfusion administrator, it is giving me following error.
Unable to refresh REST service.
Application myservicename could not be initialized.
Reason: The application does not contain any rest enabled CFCs.
The application does not contain any rest enabled CFCs.
I have save my cfc to webroot of iis and update the root path of rest service through coldfusion administrator. Then above error is gone and got the green message 'Server has been updated successfully'. But still not accessible through any url. Still getting 404 error. Can any one point me where i am doing wrong? Or help me to resolve this issue.
Using either locally installed openui5-sdk-1.18.10 or here https://openui5.hana.ondemand.com/#resources/testsuite/welcome.html, when trying to access the testsuite, the response is HTTP Status 404 - Resource could not be found!
It seems the referenced link is currently invalid. Try the following instead:
SAPUI5:
https://sapui5.hana.ondemand.com/sdk/resources/testsuite
OpenUI5:

I have a problem downloading particular file types by WebClient. So there are no problems with usual types - mp3, doc and others, but when I rename file extension to config it returns me:
InnerException = {System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.
at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult)
when I'm trying to access this file in browser (http://localhost:3182/Silverlight.config) - it's a usual xml file within - server returns me following error page:
Server Error in '/' Application.
This type of page is not served.
Description: The type of page you have requested is not served because it has been explicitly forbidden. The extension '.config' may be incorrect. Please review the URL below and make sure that it is spelled correctly.
Requested URL: /Silverlight.config
So I suppose this hapens because of some server configuration, which blocks files of unknown type.
downloading code is simple:
WebClient webClient = new WebClient();
webClient.OpenReadCompleted += new OpenReadCompletedEventHandler(webClient_OpenReadCompleted);
webClient.OpenReadAsync(new Uri("../Silverlight.config", UriKind.RelativeOrAbsolute));
completted eventhandler omitted for simplicity.
I'm not sure this is possible.
The .config extension is handled by the ASP.NET engine, for security reasons (sensitive data like connection strings need to be kept safe and hidden from unauthorized viewers).
This means that visitors cannot view your web.config file's content by simply entering "www.example.com/web.config" into their browser's adress bar.
EDIT : actually you can but I don't recommand it. If you really need to do it, you have to remove the mapping between the .config extension and ASP.NET ISAPI filter in IIS.
