Does Syncfusion Dashboard web data source support POST http methods? - rest

Does Syncfusion Dashboard web data source support POST http methods?
If yes, so how set it up?
Thanks!

HTTP Post requests additional data from client to server in the message body, where message body will be like JSON, XML, TEXT etc. This may result in the creation of a new resource or the updates of existing resources or both. In contrast, HTTP Get requests include all required data in the URL. So we support HTTP Get method since POST method is not valid use case.

WWW::Mechanize::Chrome capture XHR response

I am using Perl WWW::Mechanize::Chrome to automate a JS heavy website.
In response to a user click the page among many other requests, requests and loads a JSON file using XHR.
Is there some way to save this particular JSON data to a file?
To intercept requests like that, you generally need to use the webRequest API to filter and retrieve specific responses. I do not think you can do that via WWW::Mechanize::Chrome.
WWW::Mechanize::Chrome tries to give you the content of all requests, but Chrome itself does not make the content of XHR requests available ( https://bugs.chromium.org/p/chromium/issues/detail?id=457484 ). So the approach I take in (for example ) Net::Google::Keep is to replay the XHR requests using plain Perl LWP requests by copying the cookies and parameters from the Chrome requests-
Please note that the official support forum for WWW::Mechanize::Chrome is https://perlmonks.org , not StackOverflow.

Using JSON Search Queries with a GET request in JMeter

My org is trying to use JMeter as part of a test automation suite to test some back end REST APIs. Currently one of them supports using JSON queries as a way to get filtered results back from a GET request.
We are using the JMeter UI to create these tests and since all the other API calls work under the HttpClient3.1 HTTP Request implementation that is the implementation that I am currently using to get this to work. With this implementation I get the following when looking at the failure in the results tree (response data portion) I have made the error slightly more generic to protect some IP:
java.lang.IllegalArgumentException: Invalid uri 'https://server:port/restservice/v1/users?firstname_query={"in":["User1FirstName","User2FirstName"]}': Invalid query

I have also tried the same request using the Java implementation and get a similar result.
If anyone has any ideas or if you need more information let me know and thank you again in advance for any help you may be able to provide.
Your HTTP Request configuration is a little bit incorrect. JSON entities contain braces {} which are not allowed in URLs so you need to encode them.
Configure your HTTP Request sampler like:
Make sure "Encode" box is ticked.
And this way you will be able to send JSON with HTTP GET Requests. You can use View Results Tree listener to inspect request and response details:
You might also need to add HTTP Header Manager to your Test Plan and configure it to send Content-Type header with the value of application/json. See Testing SOAP/REST Web Services Using JMeter article for more details on properly configuring JMeter for testing REST APIs.

Backbone Request Payload

Hi,
I am a newbie to Backbone, My Rest Server Components Accept Only XML Requests, can Anybody show an example how do i send a xml to a rest api put request.
Backbone uses JSON by default, so to use XML you need to overwrite Backbone.sync. Take a look at this answer: How to override Backbone.sync?

How to deal with this situation building a REST API?

I got this problem, I have built a rest api and I don't know how to deal with this:
When the javascript client (Marionette.js) is in charge of making the views, I don't have problems, because as it is known, it just requests an url (e.g. example.com/user/37), the server retrieves a json with {id:'37', name:'Peter', age:'24'} (there is one controller class named User) and Marionette shows that data in the view. But if the user enter to example.com/user/37 by the browser it will show just {id:'37', name:'Peter', age:'24'} without any view. What can I do if I want to see the same view in both cases?
If you're trying to serve up HTML or JSON from the same endpoint then your server should be making that decision based on the request's Accept header. If the request's Accept header is application/json then your server should return just the JSON ortherwise return the HTML.
You can see that SoundCloud uses the same technique for returning XML or JSON from their API:
Resources are returned as XML by default, or JSON if a .json extension is appended to the resource URI. We encourage you to use JSON. You can also send an appropriate Accept header specifying the format you would like. For example, a request with the header Accept: application/json will return resources represented as a JSON document.
What you are trying to do is pratically impossible.
why ?
When your first enter the url example.com it's the server that responds with all the artifacts that compose your application (html, js, css ...) and the browser display it.
Now, when you enter ther url example.com/user/37 the server only sends the JSON data without any html, js or css, so the browser display the raw data he received.
What you are trying to do is to force the server to give two responses (JSON or html/js/css) depending on the user request.
You can do it, but it would be so complicated that's not worth the efforts.

Can I change the headers of the HTTP request sent by the browser?

I'm looking into a restful design and would like to use the HTTP methods (POST, GET, ...) and HTTP headers as much as possible. I already found out that the HTTP methods PUT and DELETE are not supported from the browser.
Now I'm looking to get different representations of the same resource and would like to do this by changing the Accept header of the request. Depending on this Accept header, the server can serve a different view on the same resource.
Problem is that I didn't find a way to tell my browser to change this header.
The <a..> tag has a type attribute, that can have a mime type, looked like a good candidate but the header was still the browser default (in Firefox it can be changed in about:config with the network.http.accept.default key).
I would partially disagree with Milan's suggestion of embedding the requested representation in the URI.
If anyhow possible, URIs should only be used for addressing resources and not for tunneling HTTP methods/verbs. Eventually, specific business action (edit, lock, etc.) could be embedded in the URI if create (POST) or update (PUT) alone do not serve the purpose:
POST http://shonzilla.com/orders/08/165;edit
In the case of requesting a particular representation in URI you would need to disrupt your URI design eventually making it uglier, mixing two distinct REST concepts in the same place (i.e. URI) and making it harder to generically process requests on the server-side. What Milan is suggesting and many are doing the same, incl. Flickr, is exactly this.
Instead, a more RESTful approach would be using a separate place to encode preferred representation by using Accept HTTP header which is used for content negotiation where client tells to the server which content types it can handle/process and server tries to fulfill client's request. This approach is a part of HTTP 1.1 standard, software compliant and supported by web browsers as well.
Compare this:
GET /orders/08/165.xml HTTP/1.1
or
GET /orders/08/165&format=xml HTTP/1.1
to this:
GET /orders/08/165 HTTP/1.1
Accept: application/xml
From a web browser you can request any content type by using setRequestHeader method of XMLHttpRequest object. For example:
function getOrder(year, yearlyOrderId, contentType) {
var client = new XMLHttpRequest();
client.open("GET", "/order/" + year + "/" + yearlyOrderId);
client.setRequestHeader("Accept", contentType);
client.send(orderDetails);
}
To sum it up: the address, i.e. the URI of a resource should be independent of its representation and XMLHttpRequest.setRequestHeader method allows you to request any representation using the Accept HTTP header.

I was looking to do exactly the same thing (RESTful web service), and I stumbled upon this firefox addon, which lets you modify the accept headers (actually, any request headers) for requests. It works perfectly.

I don't think it's possible to do it in the way you are trying to do it.
Indication of the accepted data format is usually done through adding the extension to the resource name. So, if you have resource like
/resources/resource
and GET /resources/resource returns its HTML representation, to indicate that you want its XML representation instead, you can use following pattern:
/resources/resource.xml
You have to do the accepted content type determination magic on the server side, then.
Or use Javascript as James suggests.
ModHeader extension for Google Chrome, is also a good option. You can just set the Headers you want and just enter the URL in the browser, it will automatically take the headers from the extension when you hit the url. Only thing is, it will send headers for each and every URL you will hit so you have to disable or delete it after use.
Use some javascript!
xmlhttp=new XMLHttpRequest();
xmlhttp.open('PUT',http://www.mydomain.org/documents/standards/browsers/supportlist)
xmlhttp.send("page content goes here");
