When creating a web hook within TFS (to access an external rest service url), I get a 401 error when testing (within the TFS application). I think call is not hitting API at all.
Below is the response I can see
Status Code: 401
Reason Phrase: Unauthorized
HTTP Version: 1.1
Headers:
{
Server: Microsoft-IIS/7.5
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM

}
Any help would be appreciated!
The error ID 401 usually related to the authorization.
You could first use postman to double check user ID access to the API.
Also use week hook to access some other rest service url such as the example in Web Hooks. This will narrow down if the issue related to rest service url.
Besides try to use Basic Authentication, you can use alternate account instead. How to please take a look at:Protecting a VSTS Web Hook with Basic Authentication
First time asking a question here. I'm a beginner at this, but i'm truly stumped at the problem i'm facing.
Browsers in use:
Safari and Firefox (both on Mac OS Sierra)
Firefox (Linux - Ubuntu 16.04.2)
I am registered as an Uber Developer and have registered an App in the Dashboard. I'm only using the Server Token for authentication at the moment. In the Dashboard, I have set the following entries in the "Authorizations" tab of the App for CORS (Optional URI for CORS Support):
http://localhost:8000 <-- web server in my PC
https://subdomain.mydomain.com <--- remote web server
A few months ago i created a web app using HTML, CSS and JS (with Jquery v2.2.4) to play around with the Ride Estimates API and was able to get it to report data for many locations in my area successfully. Somehow it no longer works. I'm trying to fix that and improve the functionality. However, i just can't get past the initial query to the API because of CORS issues that were not existent before.
My API URL is:
https://api.uber.com/v1/estimates/price?start_latitude=8.969145&start_longitude=-79.5177675&end_latitude=8.984104&end_longitude=-79.517467&server_token={*********SERVER*TOKEN**********}
When i paste that in the address bar of the browser i get valid JSON:
{"prices":[{"localized_display_name":"uberX","distance":1.58,"display_name":"uberX","product_id":"811c3224-5554-4d29-98ae-c4366882011f","high_estimate":3,"surge_multiplier":1.0,"minimum":2,"low_estimate":2,"duration":420,"estimate":"2-3\u00a0$","currency_code":"USD"},{"localized_display_name":"X English","distance":1.58,"display_name":"X English","product_id":"8fe2c122-a4f0-43cc-97e0-ca5ef8b57fbc","high_estimate":4,"surge_multiplier":1.0,"minimum":3,"low_estimate":3,"duration":420,"estimate":"3-4\u00a0$","currency_code":"USD"},{"localized_display_name":"uberXL","distance":1.58,"display_name":"uberXL","product_id":"eb454d82-dcef-4d56-97ca-04cb11844ff2","high_estimate":4,"surge_multiplier":1.0,"minimum":3,"low_estimate":3,"duration":420,"estimate":"3-4\u00a0$","currency_code":"USD"},{"localized_display_name":"Uber Black","distance":1.58,"display_name":"Uber Black","product_id":"ba49000c-3b04-4f54-8d50-f7ae0e20e867","high_estimate":6,"surge_multiplier":1.0,"minimum":4,"low_estimate":4,"duration":420,"estimate":"4-6\u00a0$","currency_code":"USD"},{"localized_display_name":"Uber SUV","distance":1.58,"display_name":"Uber SUV","product_id":"65aaf0c2-655a-437d-bf72-5d935cf95ec9","high_estimate":7,"surge_multiplier":1.0,"minimum":5,"low_estimate":5,"duration":420,"estimate":"5-7\u00a0$","currency_code":"USD"}]}
I then proceed to set up JS (w/ JQuery) code in webpage...
var url = "https://api.uber.com/v1/estimates/price?start_latitude=8.969145&start_longitude=-79.5177675&end_latitude=8.984104&end_longitude=-79.517467&server_token={*********SERVER*TOKEN**********}";
$.getJSON(url, function(result){
console.log(result);
});
Uploading the HTML and JS to my remote web server and then loading the webpage in any of my browsers yields a 200 status from Uber API. However, the console log shows CORS blocking my request (PROBLEM #1):
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.uber.com/v1/estimates/price?start_latitude=8.969145&start_longitude=-79.5177675&end_latitude=8.984104&end_longitude=-79.517467&server_token={*********SERVER*TOKEN**********}. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).
Then, in the Inspector view of both Mac Browsers, under the Network / Resources areas, i see the 200 Status message from the GET request. However, along with the Response message (PROBLEM #2):
SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data
The Request Headers are:
GET /v1/estimates/price?start_latitude=8.969145&start_longitude=-79.5177675&end_latitude=8.984104&end_longitude=-79.517467&server_token={*********SERVER*TOKEN**********} HTTP/1.1

In Firefox for Linux i sometimes don't get the Syntax Error; i always seem to get it on the Mac Browsers. In Linux, when i do get that error, then clicking on the "Edit and Resend" Headers button (resending the Headers but without really editing the Headers), the Syntax Error disappears and the Response text actually shows the Uber API Object that is supposed to be there... but i still get the CORS Blocked message on the Console Log. I really don't understand why this is, but it seems contradictory. In the end, i am unable to get to use the API data that, using the same method months ago, i could get for several dozens of locations.
I have looked for answers in similar questions but so far have found none that apply to my case. Any help will be greatly appreciated. Getting really frustrated... really stuck here.
This issue was caused by the API not including the header correctly. This issue is resolved and the api is now working as expected. Also, the allow origin header will only be returned in a response if an origin is specified in the request.
I am building a Flask-based REST API and using Flask-JWT to handle JWT auth. I also want to use the built in roles management with Flask-Security. However, Flask-Security's #roles_required() decorator assumes I am showing a Flask view when it fails.
Here is my token endpoint (which is working as I want):
$ http POST localhost:5000/auth/token username='test' password='test'
HTTP/1.0 200 OK

}
Here is a successful response to a resource that does not have any role requirement (using only #jwt_required) This is also working as I want:

When I do the same for a resource that has roles required (such as admin in this example), it seems to assume I have a page to display such as /login which I do not since it is a headless REST API:
$ http GET localhost:5000/admin Authorization:'JWT eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE0NDcwMDQ3NDYsIm5iZiI6MTQ0NzAwNDc0NiwiZXhwIjoxNDQ3MDA1MDQ2LCJpZGVudGl0eSI6MX0.RFIeaLuvJNM9fDjFYFQ7sh_WaDVU-_aM7e46tVJzlBQ'

I know Flask-Security uses Flask-Principal behind the scene for its roles management (#roles_required, etc.) and it ties into the RoleMixin and UserMixin for the datastore which is very nice. However, if there is no way to get Flask-Security to just allow the resource through without using my JWT header, then maybe the best bet is to build my own decorators which uses Flask-Principal to manage the roles.
Does anyone have any experience with this? The idea is that the entire front end can and will be built in whatever language we need and that means it may not be Flask's templates/views which is what Flask-Security appears to be doing.
Thank you for any insight anyone can provide!
Instead of a redirect, you would want to respond with an HTTP status code 403.
Your best bet is indeed to create your own decorator to manage the roles, and move away from using Flask-Security entirely.
The author of Flask-Security has mentioned that there are better ways to secure APIs, and it makes even more sense as the library is not maintained.
Flask-JWT or Flask-JWT-Extended are perfect candidates for this task. The former would require a bit more boilerplate to get things going. There is a stale PR suggesting an API to support roles, that you could use to create your own decorator if you decide to go with Flask-JWT.
The Flask-JWT-Extended docs suggest a simpler solution that might fit your case. You should follow the custom decorators section of the documentation for the full example, but here's the decorator in the nutshell:
from functools import wraps
from flask import jsonify
from flask_jwt_extended import (
verify_jwt_in_request, get_jwt_claims
)
def admin_required(fn):
#wraps(fn)
def wrapper(*args, **kwargs):
verify_jwt_in_request()
claims = get_jwt_claims()
if claims['roles'] != 'admin':
return jsonify(msg='Admins only!'), 403
else:
return fn(*args, **kwargs)
return wrapper
This code looks for a roles claim in the JWT, and returns a 403 response if it is not admin.
I was trying to use it for Single sing on. I was able to successfully secure my web services/pages and want to extend it to my REST APIs (services) as well. I am using CAS 4.0.0.
I followed this link http://jasig.github.io/cas/4.0.0/protocol/REST-Protocol.html and change the web.xml as suggested and added the following jar to my CAS deployment WEB-INF/lib folder:
cas-server-integration-restlet-4.0.0.jar
org.restlet.jar
org.restlet.ext.spring.jar
org.restlet.ext.servlet.jar
The Call to the "v1/tickets" is reaching the restlet-frame work but I am getting a 404 error to my rest client

Can you Please help me identify the issue with the set-up or point me to a detailed documentation.

The endpoint is in lower-case: can you try: /v1/tickets?
I am trying to install a custom service using these instructions and these commands to add the service. When I issue the curl command, instead of getting added, I get this error:

What is going on here? My cluster is installed perfectly and I can see the dashboard and metrics and stuff. Just can’t seem to add a custom service. Please help out. Thanks!
I figured out what was wrong. When using Ambari 1.6.1, it automatically downloads and uses HDP 2.1. The folder structure in the link says: cd /var/lib/ambari-server/resources/stacks/HDP/2.0.6/services. I changed it to: cd /var/lib/ambari-server/resources/stacks/HDP/2.1/services. Problem solved. So stupid. So simple. So much frustration. Such hopeless documentation.
