Can we send POST HTTP requests in Google Chrome when using Rest Services?
I have tried few extensions but I need directly from Chrome browser
I think, using the URL bar will always result in a GET.
To send POST requests from a browser, set up an HTML <form> with method="POST", use the action attribute for the REST-URL and input tags for other parameters.
You can do the post and get in the same way as the browser does.
You can use the header to put in information in key, value pair.
Here is a tutorial on how you can do it - Send POST data using XMLHttpRequest
But it would be better if you use chrome extension POSTMAN which is very extensive and clean for testing REST services.

I'm trying to replicate a post request done normally by a website form via postman but the server returns 500 error.
the form website URL that I'm dealing with is here.
what I have done so far is investigate the network request using chrome or safari dev tools, copy the request as cURL, import the cURL in postman and do the request.
what can be the possible reasons for the failure and what are the alternative ways to achieve the same result?
Postman Headers:
Most probably you must have used invalid request body. The browser shows parsed json body and you might have copied incomple request body.
To get full body click view source and copy the full content.
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.
I'm very new to API testing.
I'm trying to make use of Google Chrome's developer tools to understand and explore this subject.
Question 1:
Is it possible to get the response (possibly in JSON format) of a simple GET request using chrome developer tools?
What I'm currently doing is:
Open chrome developer tools
Go to Network tab
Clear existing logs
Send a post request simply by hitting a URL. e.g. https://stackoverflow.com/questions/ask
Check the corresponding docs loaded
Question 2:
What are the relevance "Reponse Headers" shown on the image above? I mean, am I correct to think that this is the response I am getting after doing the GET request?
Any help or references you can give are much appreciated!
If you want to test a rest api I sugest you get postman which is meant for that purpose.
Going to your questions:
Question 1: Is it possible to get the response (possibly in JSON
format) of a simple GET request using chrome developer tools?
The first point to make clear is that it is the server who will or will not send a json response to the browser. Not the browser who can choose to see any response as json.
If you send a GET request that the server responds with a json object or json array and the Content-type header is set to application/json, you will see that response already formated in the main window of the browser.
If the Content-type is set to text/html, for example, then you will still get the a json text as response in the main window but it won't be nicely formated. Depending on how the response was sent, sometimes you can see it nicely formatted by left clicking the browser window and selecting view source page.
For this you don't need developer's tools unless you want to see how long did it take to receive the response, or check the headers for some specific value, etc, but nothing to do with receiving the response or rendering it on screen.
Developer's tools is more usefull if you are working with javascript/jquery and/or if you are sending ajax requests (GET or POST). In these cases you can debug the function and also see the ajax request to check what actually went out from your browser and what was received as a response.
Question 2: What are the relevance "Reponse Headers" shown on the
image above? I mean, am I correct to think that this is the response I
am getting after doing the GET request?
In the response you get the two things, the headers, and the content. The json objects you see are part of the content not the headers.
The headers will tell the browser, for example, that the body is json (vs. an html documenet or something different), besides of other information like cache-control, or how long the body is.
Search for http headers for more information on which are teh standard headers.
To answer your questions narrowly:
Is it possible to get the response (possibly in JSON format) of a simple GET request using chrome developer tools?
Yes! Just click the Response tab, which is to the right of the Headers tab that's open in your screenshot.
What are the relevance "Reponse Headers" shown on the image above? I mean, am I correct to think that this is the response I am getting after doing the GET request?
Yes, these are the HTTP headers that were sent with the response to your request.
The broader question here is "how do I test a REST API?" DevTools is good for manual testing, but there are automated tools that can make it more efficient. I'll leave that up to you to learn more about that broad topic.
Neo4j API url is: http://localhost:7474/db/data
When I use Chrome visiting this url, which is a GET request. This is the response I got
But when I use the restful client such as POSTMAN to make a g request.
This is the response I got.
My questions are
Both are GET request to the same url. Why Chrome browsing get a html page in return but Postman Request get JSON Response in return.
How Neo4j does that?
Is Neo4j using user agent detection, and if it is a browser visiting, it will give HTML page as response. And if it is a rest client request, it will give json response?
Thanks!
They use media type negotiation header. For example when requesting this site my browser sends a header like that:
Accept: "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
As you can see it accepts primarily html, if that's not available then xhtml, then pure xml, and if that's not available - it accepts whatever the server can throw at it. Neo4j's website tries to serve content in that order. Postman likely just specifies application/json, or nothing at all (the application determines the default media type then), hence the response.
I have written my own API which requires basic authentication, such as:
user:james
pass:1111
I can call resources using urls such as:
http://api.james.com/myapi/orders/get
I wish to be able to use the REST client in PHPStorm but I cannot work out how to send my authentication details. Does anyone know how to do this? Do you have to setup a Proxy server, or can you pass the authentication somehow in the URI above?
Any help would be appreciated.

For usage Basic Auth you will need send header 'Authorization', for example:
Authorization: Basic amFuc29uQG1haWwucnU6MTIzNDU2
Value of this header you can get from debug console of your browser (firebug in FireFox or developer tools in Chrome). Start GET request from your browser, when you will need authorize - do it. Than open debug console 'network' tab and try this request one more time.
Now you will find in headers new one 'Authorization', that formed by browser when you was authorized.
Just copy content of this header and use it in PhpStorm REST-client.
