Hy,
I'm working on a jsFiddle with a openlayers example in it.
http://dev.openlayers.org/releases/OpenLayers-2.11/examples/snapping.html
At the moment it's not working because it's not getting a response for the http request to get data. How do I fix that?
The jsFiddle is here: http://jsfiddle.net/TcuxA/6/
Go to the line "// create three vector layers" in the script.
There are 3 requests for data. If you type the URLs in your browser you get the JSON, but my firebug gives 3 errors when I run the jsFiddle.
I tried fixing with jsFiddle echo ( http://doc.jsfiddle.net/use/echo.html ), but that didn't work. I don't know how to change the script to load the data otherwise.
Why can't I get the json by these URLs? What are good sollutions?
What you are experiencing is an exception being thrown by the XMLHttpRequest object, because you are using AJAX to call elements from different domain. This is better said, for example, in here:
"The XMLHttpRequest object is prevented from calling web services from outside its own domain. This is sensible given that if you called a script in one place and it, in turn, called a script on another server, it could leave an application open to all sorts of malicious scripts, hacks and exploits."
So the easiest way to do is to code it locally and call a local copy of the files (poly.json, line.json and point.json) that would reside on your local server. For testing if all displays on a map you could hard-code the files into your code. I am not sure how it could be achieved otherwise.
A good solution can be this : using github responses . You can store your example in github, along with the predefined XHR requests responses.

The following code used to work but not anymore and I'm seeing junk HTML with success code of 200 returned.
response = urlopen('https://www.tipranks.com/api/stocks/stockAnalysisOverview/?tickers='+symbol)
data = json.load(response)
If you open the page in chrome you will see the JSON file format. But when opened in python I'm now getting:
f1xx.v1xx=v1xx;f1xx[374148]=window;f1xx[647467]=e8NN(f1xx[374148]);f1xx[125983]=n3EE(f1xx[374148]);f1xx[210876]=(function(){var
P6=2;for(;P6 !== 1;){switch(P6){case 2:return {w3:(function(v3){var
v6=2;for(;v6 !== 10;){switch(v6){case 2:var O3=function(W3){var
u6=2;for(;u6 !== 13;){switch(u6){case 2:var o3=[];u6=1;break;case
14:return E3;break;case 8:U3=o3.H8NN(function(){var Z6=2;for(;Z6 !==
1;){switch(Z6){case 2:return 0.5 - B8NN.P8NN();break;}}.....
What should I be doing to adapt to the new backend change so that I can parse the JSON again.
It is a bot protection, to prevent people from doing what you are doing. This API endpoint is supposed to be used only by the website itself, not by some Python script!
If you delete your site data and then freshly access the page in the browser, you'll see it first loads the HTML page that you see which loads some JavaScript, which then executes a POST to another URL with some data. Somewhere in the process a number of cookies get set and finally the code refreshes the page which then loads the JSON data. At this point visiting the URL directly returns the data because the correct cookies are already set.
If you look at those requests, you'll see the server returns a header server: rhino-core-shield. If you google that, you can see that it's part of the Reblaze DDoS Protection Platform.
You may have luck with a headless browser like ghost.py or pyppetteer but I'm not sure how effective it will be, you'll have to try. The proper way to do this would be to find an official (probably paid) API for getting the information you need instead of relying on non-public endpoints.
I am new to wso2 API Manager, trying to set it up expose my plain HTTP POST back end calls as a REST API. I am sure this is not a new pattern that I am trying to achieve here. The requirement is to convert the JSON data coming in (has array structures) into the HTTP URL query string parameters.
After some research through the documentation and other posts on this forum, decided to go with the script mediator that would parse the JSON data and convert it to a string that can be appended to the endpoint URL. Some how I am not able to achieve this.
I have followed the following post that seems to be very straight forward. As the original poster suggested, I am also not able to use getPayloadJSON() method. Even have trouble using the work around suggested there due to JSON.parse() not working.

Also, this approach of editing the service bus configuration from source view does not sound like the correct option. Is there another elegant solution to achieve this? Thanks for the help in advance.
I was able to get both methods working by using an external script instead of the inline java script. Thanks
I'm trying to replicate a request I make on a website (ie zoominfo.com) using the same http POST parameters using chrome rest console, but it fails for some reason. I'm not sure if there is a missing field or it's not working because the origin of the request isn't valid.. can someone point me out in the right direction? Below is a detailed explanation of the experiment:
ORIGINAL CASE
basically if I go to zoominfo.com (registered and all) I see a form page that I need to fill:
if I hit enter.. the site makes an ajax call. If I open the chrome web dev tools, and open the network tab, I see the details of the ajax call:
notice the body of the POST has the name John Becker in it:
{"boardMember":{"value":"Include","isUsed":true},"workHistory":{"value":"CurrentAndPast","isUsed":true},"includePartialProfiles":{"value":true,"isUsed":true},"personName":{"value":"john%20becker","isUsed":true},"lastUpdated":{"value":0,"isUsed":true}}
the response is shown under the respones tag:
WHAT I'M TRYING TO DO
basically replicate what i've done above using a REST console (note: so there is nothing illegal here.. i'm just replacing a chrome browser action with a rest client action.. i'm not hacking anyone and i'm not getting information I can't get the normal way, but if someone feels otherwise.. please let me know)..
so I plug in the same parameters as above into the rest console:
now i'm not sure about authentication.. but just to be safe, i entered the same user name and pwd i have for the site into the REST console:
but then I keep on getting an error as a response to my rest console's request:
UPDATE: CORRECT ANSWER:
so according to JMTyler's answer.. I had to simply include criteria in the RAW body, and convert it to url encoding.. in addition to that, I had to explicitly set the encoding in the rest console body..
looking at the chrome inspector more closely, it turns out that I simply had to click on view source:
to get the url-encoded value that I needed to put in the RAW body in the rest console:
I also had to set encoding to gzip,deflate,sdch and things worked fine!
The form is posting all that JSON under the field criteria. You can see this in the screencap of the chrome dev console you posted.
Just start your raw body in rest console with criteria= and make sure the json has been url-encoded. That should do it.
No authentication is needed because none is passed through the headers in your screencap. Any cookies you have when you load the page normally will also be loaded through rest console, so you don't need to worry about explicitly setting them.
Reading your problems I'll make an educated guess:
zoominfo does not provide an RESTful API.
Rest-Console understands and uses HTTP Authentication, which is different from the authentication handler zoominfo implemented.
A possible way to work around may be:
Make a call to the login-page via rest console. you'll get back cookies and a lot more.
In subsequent requests to zoominfo be sure to include those cookies (likely holding some session information) in your request, therefore acting like a browser.
I am trying to understand how POST and/or GET methods work in terms of the actual browser.
I am attempting to contact an API which requires API key, method you wish to use on their side, and an IP address at the minimum.
My original idea was to do something like this:
I feel like I'm on the right track, it does something and gets an error as opposed to telling me the page does not exist. I'm expecting either JSON or XML in response as the API supports both but instead I get this error:
This page contains the following errors:
error on line 1 at column 1: Document is empty
Below is a rendering of the page up to the first error.
Upon studying the documentation of the API more, I found something saying that methods are called using HTML form application/x-www-form-urlencoded and the resuource models are given as form elements.
I tried researching what that means to see what the problem was and found this site http://www.w3.org/TR/xforms11/ but I'm still unclear.
Ideas?
It seems to mean that the application is expecting a POST method but you're doing a request with a GET method (when you use the querystrings).
Since you can't just do browser requests using POST using the address bar, you may need to:
Construct a simple JS function that does a xmlhttprequest request using that method instead, and running it from the console;
Create a simple HTML page that automates the above process, allowing you do make POST calls;
Using CURL instead, which is a great tool for testing those kinds of requests.
I have a simple RESTful web service and I wish to test the PUT method on a certain resource. I would like to do it in the most simple way using as few additional tools as possible.
For instance, testing the GET method of a resource is the peak of simplicity - just going to the resource URL in the browser. I understand that it is impossible to reach the same level of simplicity when testing a PUT method.
The following two assumptions should ease the task:
The request body is a json string prepared beforehand. Meaning, whatever is the solution to my problem it does not have to compose a json string from the user input - the user input is the final json string.
The REST engine I use (OpenRasta) understands certain URL decorators, which tell it what is the desired HTTP method. Hence I can issue a POST request, which would be treated as a PUT request inside the REST engine. This means, regular html form can be used to test the PUT action.
However, I wish the user to be able to enter the URL of the resource to be PUT to, which makes the task more complicated, but eases the testing.
Thanks to all the good samaritans out there in advance.
P.S.
I have neither PHP nor PERL installed, but I do have python. However, staying within the realm of javascript seems to be the simplest approach, if possible. My OS is Windows, if that matters.
I'd suggest using the Poster add-on for Firefox. You can find it over here.
As well as providing a means to inspect HTTP requests coming from desktop and web applications, Fiddler allows you to create arbitrary HTTP requests (as well as resend ones that were previously sent by an application).
It is browser-agnostic.
I use the RESTClient firefox plugin (you can not use an URL for the message body but at least you can save your request) but also would recommend curl on the command line.
Maybe you should also have a look at this SO question.
